Our Products

The HE Series make-up air units offer the most efficient method available to heat make-up air. Direct fired make-up air heaters may be considered to be 100% efficient because no heat is vented to the atmosphere.

The theoretical 100% efficiency should be reduced to 92% due to water vapor being formed as a natural by-product of the combustion process. Units are available with heating capacities up to 14,000 MBH and air capacities up to 100,000 CFM. Units are also available in variable capacity, dual capacity, air curtain, and / or heat recovery configurations.

Space Temp Air Turnover Systems offer a solution to the universal problems of heating high bay areas: stratification, uneven temperature, and high energy costs. Other heating systems, most notably unit heaters and infrared heaters, tend to intensify stratification, and provide “spot” heating. These systems cannot provide a uniform space temperature and increase the amount of energy required to heat the space. Learn More

Engineered Air manufactures a variety of products that can be used for dehumidification.

Our PD Series of Pool Dehumidifier units cool, dehumidify and reheat air from pool areas. They can also incorporate heat recovery of the exhaust air for additional operating cost savings.

PD Series

Indoor / Outdoor Pool De-Humidifiers

 

 

Features


  • Indoor or outdoor models are available
  • Corrosion resistant Heresite coating is used on DX cooling and condenser coils
  • Compressor energy (heat) is reclaimed and used to heat pool water
  • Latent heat loss from the pool a water evaporates is reclaimed and rejected back into pool water and the pool supply
  • Auxiliary remote air cooled condensers are available which allows the system to provide space air conditioning
  • A variety of control options are available

Options


  • Return air fans and/or mixing boxes can be provided when required.
  • Auxiliary Engineered Air heating components (DJ, DG, electric, water, or steam coils) can be added to give a complete package.
  • Free cooling packages including motorized dampers (outside air, return air and exhaust air), as well as all economizer controls are available.
  • Whirlpool de-superheaters (selected for higher pool water temperature) are available.
  • Exhaust air heat reclaim systems using air to air, or heet pipe coils air available.

Benefits


Evaporating from the surface of an indoor swimming pool causes two major concerns. The first and most obvious problem relates to the resulting high relative humidity level.

During periods of low outside air temperatures, high indoor humidity causes problems with condensation and frost on windows.

A more serious problem could result if moisture penetrates into the building structure, where it could condense and freeze thereby causing structure damage.

The second major concern is heat loss from the surface of the swimming pool. As moisture evaporates from the surface of the pool, a large amount of heat is lost as the latent heat of evaporating is carried away by the moisture. If the humid air was simply exhausted, all of this latent heat would be lost and would have to be replaced by heating the pool water.

This discussion makes the benefits of an Engineered Air PD Series pool de-humidifier obvious. These benefits can be summarized as follows:

  1. Reduced pool heating costs due to reclamation of latent heat of evaporating from pool surface.
  2. Reduced space humidity levels prevents possible structural damage due to condensation.
  3. Space comfort conditions are also obviously improved by the lower relative humidity level. If a remote (outdoor) air-cooled condenser is used, the resulting space cooling ability also has obvious benefits.

Engineered Air manufactures a variety of products that can be used for dehumidification. Our CD Series of Ice Rink Dehumidifier units solve the condensation problems frequently encountered in skating and curling rinks.

CD Series

Ice Rink De-Humidifiers

 

 


Application


A common problem encountered in skating or curling rinks is fog and / or moisture condensing and dripping from the structure. This occurs during periods when the space temperature is low and moisture content of the air relatively high. Condensation problems can occur throughout the year but more frequently occur during the spring and fall seasons.

In pool environments, outside air can often be used to condition the space and reduce the moisture level. This approach cannot be used in a rink environment because the outdoor air contains moisture with a higher dewpoint level than the indoor temperature of the rink. As a result, bringing in outdoor air for ventilation only adds to the fog and condensation problems.

The solution is to remove moisture from the ice rink air by using an Engineered Air dehumidifier. Our CD Series is one option. One alternative is the DWD Desiccant Gas Fired De-humidifier by Engineered Air.

  • High efficiency Engineered Air 20:1 high turndown Green Burn direct-fired burner used for desiccant wheel regeneration.
  • EngA air mixer enhances moisture removal by providing thorough air coverage onto the face of the desiccant wheel.
INTERTEK - C US - Listed

Applications


  • Ice rink
  • Critical temperature storage such as library archive storage
  • Production lines for pharmaceuticals
  • Production lines for plastic products
  • Dehumidification at fertilizer plants
  • Food drying
  • Museum
  • Environmental test room
  • Powder filinh applications

Fundamentals of Operation


  • The Engineered Air HE/DWD Series gas fired desiccant dehumidifier uses vapor pressure differential to absorb moisture on the relatively cool process air side and then drive this moisture off in the hot regeneration airstream. The process air is hence dehumidified.
  • The desiccant wheel rotates constantly through the process air and the regeneration airstreams.
  • The ambient regeneration air is heated by an Engineered Air direct fired burner (HE Series). The water molecules transferred from the process air are then discharged to the ambient.

Benefits


  • Gas fired dehumidification units do not have a DX coil and inherent freezing problems associated with a low temperature DX coil. With mechanical cooling dehumidification, the condensed moisture will freeze on the surface of the evaporating coil when the coil surface is below 32°F as is sometimes necessary to reach low dewpoint levels. As a result, the minimum achievable dewpoint is limited by frosting on the DX coil.
  • Lower operating cost — especially in areas where the electricity cost is high and the natural gas cost is low. Mechanical cooling compressors require a significant amount of electricity to provide dehumidification.
  • No water condensation issues — the mechanical cooling dehumidification evaporator will condense water which will promote undesired microbial growth in the system/
  • Lower maintenance cost — gas fired desiccant dehumidifier has fewer components to service than mechanical cooling dehumidification units.

Options


  • Mixing boxes can be provided if required.
  • Auxiliary Engineered Air cooling components (FW mechanical cooling or chilled water coil) can be added to re-cool dehumidified process air to neutral condition.
  • A sensible heat wheel can be added to re-cool the process air down stream of desiccant wheel and preheat the regeneration air upstream of Engineered Air's burner.
  • High temperature process exhaust heat (approximately 125°F to 280°F) from the building, steam or electric heat, if available, can be used in the regeneration air to reduce the required heating capacity or eliminate the direct fired burner.
  • A cooling coil (DX or chilled water) could be used as an option to re-cool the warm dehumidified air.

Optional Features


  • Piping enclosures, insulated and weather proofed for outdoor installations
  • Pipe insulation
  • Exhaust coil wash-down plenum and drain pan
  • Steel tube, aluminum fin coil
  • Special dimensions and configurations

Where should HRG Series be used?


  1. Commercial and industrial buildings, where exhaust and makeup are required for many hours of the year, the more hours the better.
  2. In installations where exhaust air temperatures are from 80°F to 200°F and where the air is not particularly corrosive. Exhaust air temperatures below 80°F tend not to be an economic source of heat, particularly where outdoor air temperatures are sub zero, and the possibility of circulating glycol at temperatures below 32°F exists, thus creating certain frosting conditions on the exhaust coil, which is a dehumidifying coil. While the control system can automatically prevent frost from forming, the efficiency of the system is low while operating in a "frost prevention" mode and energy savings may be less than anticipated.
  3. Areas of the country where the normal energy source is relatively expensive will be attractive for heat reclaim systems: the relative cost of energy seems to be rising at an alarming rate throughout all of Canada, so few areas will not find the reclaim of heat a wise economic move.

Why a HRG Series System instead of an Air to Air System?


The reclaim of heat, as developed so far, while saving heating energy, does demand the expenditure of energy in another form; fan motor horsepower to overcome the reclaim device air pressure drop. A glycol run around system requires about the same amount of extra energy to run the two fans and one pump, than an air to air system does for its two fans. However, in the glycol system, the pump may be shut off at a point when it is determined that heating savings no longer outweigh the cost for pump power.

The SI Series Oxidizer Units are self-contained air purification products designed to reduce high concentrations of odor & VOCs. They are a very economical solution, using minimal power consumption & requiring no additional chemicals or high priced media for operation and have extremely low maintenance.

The Oxidizer process is simple. High static voltage ionizes oxygen and then using basic principles of organic chemistry it naturally breaks down (oxidizes) gaseous compounds, leaving CO2, H2O and O2 as the primary end products.

For maximum results, the Oxidizer units should be connected to the suction side of any ducted system to maximize contact time between the oxidant and odorous gases.

The Oxidizer units are easily adaptable to the A-TAC1 system to create an automated air purification system, continually balancing oxidant levels with load levels for the air.

The Oxidizer will treat air problems in spaces where there are no existing air ducts2 or can be used to inject ozone into ducted air systems.

1 A-TAC is a series of IAQ sensors for air sampling on equipment regulation
2 recommended use with A-TAC system if used in occupied space.

Oxidation Process


Oxidation technology can be effectively employed to break down odorous gases formed in wastewater facilities or any industrial site that causes problems for those living or working nearby. The oxidation process allows a form of oxygen (ozone) to combine with odorous molecules to break down the chemical structure and reform the atoms into simple compounds. Ozone is found naturally in the outdoors. Ozone is created by ultra violet rays from the sun or by high voltage electrical discharge during lightning storms. EngA’s Oxidizer 2000 copies nature by using high voltage to create a concentrated ozone discharge.

The TRI MED® Patented Process


The Oxidizer 2000 produces concentrated ozone within high voltage modules. A powerful fan draws the ozone from the modules combining them with the odorous gas molecules. The mixture of ozone and odorous gases is discharged into a specially designed reaction chamber. Chemical reactions take place that result in a deodorized mixture that is discharged to atmosphere. This patented process is completed with minimal operating cost, no hazardous waste to dispose of and no costly consumables to replace.

The first HERESITE coating application to the exterior surfaces of finned tube coils took place in the early 1950s. Since that time the HERESITE baking phenolic coating has effectively demonstrated its value in protecting heat transfer coils from corrosive attack, thereby appreciably increasing equipment service life.

The excellent chemical and temperature resistance coupled with the good heat transfer properties of the HERESITE coating have made possible the outstanding results being obtained.

Engineered Air, in searching for corrosion resistant coating for finned tube heat transfer products, realized that HERESITE baked phenolic resins were far superior to any other type of coating on the market, both in terms of heat transfer characteristics and resistance to corrosive attach from an extremely wide range of chemicals.

HERESITE

Corrosion Protection

 

 


Description


HERESITE is the registered trademark for pure phenol-formaldehyde thermosetting resinous coatings.

The HERESITE coating applied to finned tube coils is the P-413 Flexible Brown Baking Phenolic Coating. This coating is applied to either aluminum, copper or steel with equal results.

We feel it is important to emphasize that HERESITE baking phenolic coatings are manufactured and sold only by HERESITE PROTECTIVE COATINGS INC. Further, the application of the HERESITE baking phenolic coating to finned tube coils is performed at the HERESITE plant in Manitowoc, Wisconsin, USA, at Engineered Air in Calgary, Alberta, Canada and at other authorized facilities.

Advantages


Practically all typed of finned tube coils used for oil, water, air, gas and process cooling (and heating) as well as a large condensing coils can be HERESITE protected against damaging environments. Currently, the HERESITE coating of air-conditioning and industrial process coils exposed to corrosive fumes and salt atmosphere is in the increase, with many new applications being found.

HERESITE coating offers a more economical solution that special metals for these applications. Typically, aluminum fin coil coated with HERESITE are more economical than copper fin coils. Special metal casing materials are unnecessary since the HERESITE coating is applied to the casing as well as to the finned tubes. Additionally, HERESITE coated aluminum fins will resist attack from most cleaning agents more successfully than copper fin coils.

Application


The present day HERESITE coating of finned tube coils is the result of many years experience during which time application equipment and procedures have been constantly improved. Today, Engineered Air has one of the largest HERESITE facilities in the world. The enables us to HERESITE coat, on a routine basis, coils up to the following size and weight:

Maximum Fin Dimensions
240” long × 78” wide × 18” deep
Maximum Weight Per Coil
4,000 pounds per coil
Fin Spacing, 1 to 3 tube rows
16 per inch maximum
Fin Spacing, 4 to 6 tube rows
14 per inch maximum
Fin Spacing, 7 and 8 tube rows
12 per inch maximum

The HERESITE coating of finned tube coils is accomplished by a multiple coat application of dipping and baking resulting in complete coating coverage of the fins, tubes, headers, casings, etc. Consequently, protection against corrosion is provided for the entire coil. Due to specialized surface preparation techniques plus the good adhesive properties of the HERESITE P-413 coating, it is possible to efficiently HERESITE coat all the usual metals used in fabricating finned tube coils.

Heating cold outside air with steam or a hot fluid is a risky business at the best of times; there is always a potential for a freezeup! But with steam of hot water, there is nothing better than Engineered Air's LAMIFLO Integral Face and Bypass Heating Coils. In the more Northern climates, with a significant number of hours per year under 32°F (0°C) outdoor air temperature, Engineered Air does recommend the use of glycol solution instead of hot water, particularly in areas where power failures are prevalent.

Full flow is sent through the coil at all times, preventing freezeup. Temperature control is maintained by a series of Face and Bypass Dampers, spaced evenly over the face of the LAMIFLO. Face dampers are employed on both the entering and eliminate unwated heat pickup.

The use of LAMIFLO Face and Bypass Dampers for makeup air applications has a very distinct advantage over valve control. A coil is selected for the very worst condition possible - and then often oversized. When the outdoor air temperature is much warmer than the design point, but still below freezing, a control valve is often oscillating between cracked open and fully closed. In one of those fully closed moments, it doesn't take long to chill and then freeze the stationary fluid in the tubes.

With LAMIFLO Face and Bypass Dampers, the steam or fluid flow is constant during the period that the outdoor air temperature is below freezing. Temperature control is achieved by metering the incoming cold air through multiple narrow heating and bypass channels to mix at the control temperature. The bypass channels have been sized to provide a pressure drop when fully open that is equal to the pressure drop through the coil, or heating channel when fully open, to assure a constant volume of air. The air streams emerging from the narrow channels are LAMINATED and mixing is virtually complete within 36” (0.9m) of the LAMIFLO section.

The advantage of LAMIFLO over conventional internal or external face and bypass dampers is clean; the homogenous air temperature mix is far superior, and downstream devices, for example, reheat coils, cooling coils, or humidifiers, need not be spaced a great distance from the LAMIFLO section to retain even velocity loading. Air pressure drop is minimal on LAMIFLO coils. Conventional bypass dampers, with all the bypass air passing over top of the heating coil, create a system effect that demands extra horsepower.

The rate of heat transfer in a QDT heat pipe is dependent not only on the size, number of rows and fins, but also on the mounting angle. The Q-TRAC controller is designed to operate the tilt mechanism on a QDT heat pipe to control tilt angle.

Controlling the rate of heat transfer via tilt angle of the heat pipe has three objectives.

  • Temperature control: supply air temperature leaving the heat pipe.

  • Frost Prevention: maximizing heat transfer while preventing the formation of frost on the exhaust leaving side of the coil.

  • Heating-Cooling changeover: by reversing the tilt angle, the direction of heat transfer is also reversed to allow summer operation.


The Q-TRAC control is a stand alone solid state device that provides proportional-integral control for all three functions when mounted on a QDT heat pipe with tilt mechanism.

The rate of heat transfer in an Engineered Air heat wheel is dependent on the rotation speed of the heat wheel.

The W-TRAC controller is designed to provide variable speed control for an Engineered Air heat wheel. By controlling the rotational speed of the head wheel, and in turn controlling the rate of heat transfer, three functions can be accomplished.

  • Control of supply air temperature leaving the head wheel.

  • Prevention of frost formation on the exhaust side of the wheel while keeping heat transfer at the maximum allowable level.

  • Heating-Cooling changeover. In heating mode heat is carried from the warm exhaust to the cold outside air. In cooling mode heat transfers from the warm outside air to the cooler exhaust air. The wheel simply rotates in either case and as such there is no difference in operation between heating and cooling. By stopping the wheel completely a free cooling mode can be provided. This is desirable if cooling is required and outside air is colder than the exhaust air.


The W-TRAC controller is a stand alone solid state device that provides proportional / integral control for all three of the above functions when mounted with an Engineered Air wheel.

When combined with a DC drive motor the W-TRAC can provide exceptional high turndown speed control. DC drive motors offer the advantage of high torque ability at very low speeds. The W-TRAC can also provide a 0-10 vdc control signal to a variable frequency drive if conditions require the use of an AC drive motor.

The Engineered Air M-TRAC controller is designed to control Engineered Air HE Series direct fired burner on make up air units. M-TRAC controller is a programmed logic device that provides a stable PI (proportional + integral) temperature control and airflow monitoring system. A dual sensor option is built in the M-TRAC controller to provide an even discharge temperature.

The M-TRAC controller has eliminated many mechanical parts such as air proving switch, damper end switch, timers and relays. The M-TRAC provides interlock between the exhaust fan and the make up air unit. This allows the M-TRAC to prove the operation of both the exhaust fan and supply fan. Reverse interlock is also available. This feature is designed for use in buildings which should not go into a negative pressure condition during start up mode.

The Engineered Air M-TRAC controller is designed to be user friendly. The controller is equipped with five diagnostic LED lights. System status can be determined by the LED color and its flashing patterns. This features allows easier troubleshooting.

The M-TRAC in its various forms can operate as either a stand-alone controller, or it can be interfaced to a higher level controller such as a C-TRAC or programmable controller. When used as a stand-alone device the controller provides most of the control requirements of a make up air unit. Standard abilities include: discharge temperature control, supply blower control, burner management, inlet damper control, auto bypass low limit, and air flow monitoring.

The Engineered Air MC Series is a line of modular water-cooled and remote air-cooled chillers (packaged air cooled are available) that range in size from 20 to 80 nominal tons. They can operate as a stand alone unit or in combination of up to 12 chiller modules to increase cooling capacity as needed. Single stand-alone models are available in the 3 to 80 ton range.

The principle of modular chiller design is that a smaller individual chiller (a module) can be connected with other modules to create a larger cooling system, either initially or over time. Sections of 6" (152mm) diameter pipe connected with Victaulic couplings are used to form a common header. This allows the common header to be pre-shipped to the job site and piped into the building piping system before the rest of the equipment arrives.

Benefits


Expandability
Allows the system to grow with the cooling load. Modules can be added at a future date without doing any piping work.

Better Capacity Control Each individual circuit is operating at its optimum efficiency point, providing a high operating efficiency even though the overall assembly is operating at partial load.

Installation
Units are connected to the header using isolation valves and flex joints, meaning they can be mounted directly onto a concrete slab. Header sections are identical to one another. They can be pre-shipped ahead of the chillers, allowing the building piping system to be pre-built.

Flexible Installation Arrangements
The external common header means that modules can be located in different parts of the room or even in separate rooms. As long as the piping is connected so that the master controller measures the system fluid temperature, the system will work effectively.

Service While Under Full Operation
Designed to allow service to all the liquid line components on any of the chillers while the system is under operation.

Redundancy
Add one more module to the system for an "N + 1" capacity so that the overall cooling system capacity is not affected when a module is taken out for regular service or needs repair. Each unit has two independent circuits. If one is lost, only that circuit is affected while all others remain operational. Each module has a fully functioning dedicated logic controller. If communication is lost with the master controller, the individual controllers will automatically take over control of each module. By presetting and staging the set points on all the local controllers, they will then control the system.

Front Serviceability
Set up so that it is front serviceable making it easy to access components requiring routine maintenance.
