Direct Gas-Fired Heater Module, for use in tempering make up air. Direct fired modular heaters are designed for natural or propane gas applications. Heaters are rated for indoor or outdoor installations in commercial occupancies. A unique feature is the self-adjusting burner profile plates allowing 2-speed and variable-air-volume applications. The plates ensure proper air velocity and pressure drop across the burner for clean combustion. Spring loaded profile plates react to the momentum of the fresh air stream, therefore, no motors or actuators are needed to drive them. Nor do they need to be manually set to a specific position.

Packages start at 1000 CFM and go up to 21,000 CFM, with external pressures up to 2″ WG. Units have large doors on both sides to provide ample access to all internal components. Direct fired module consist of galvanized enclosure control panel and stainless steel burner.

Heating applications are most commonly used in hot fluid systems for comfort conditioning of a forced air stream and in process systems for drying processes. The collector header design with internal baffles provides circuiting flexibility while eliminating the need for return bends, while the splayed header design uses return bends for circuiting in lieu of a collection header. The term “splayed” means that the coil headers are offset outward from the coil tubes. The splayed header coil always has same end connections.

This Modular Hot Water Coil housing has been designed so that there is easy access to either side of the coil. Over sized doors offer plenty of room through which to clean and maintain the coil from either side of the housing. Blank off plates secure the coil and help maintain velocity across the coil. Modular design also lends its self to easier installations since modules bolt together on location.

Providing clean and tempered makeup air to meet your application needs. The push-through design ensures that combustion fumes will not enter the fresh air stream.

The Modular Indirect Fired Bent Module is designed to deliver clean air into an indoor environment. The IBT heater module is approved in the United States and Canada. The unit is listed to the ANSI Z83.8-2006 and CSA 2.6-2006 standards. Each furnace has a 6:1 Turndown Ratio and a maximum Turndown of 28:1 for the entire unit, depending on total required BTU Capacity and number of furnaces in the unit.

Every unit is programmed to start in high fire mode to ensure consistent light-off and is equipped with an electronic, Vernier-type fully-modulating control system. The duct furnaces are all type-409 stainless steel, and certified by the American Gas Association and approved by the Canadian Gas Association. Each model utilizes a single modulating stage, and between zero and three additional ON/OFF stages depending on the required heat output. In addition, the speed of its power-vent blower on the single modulating furnace is varied as the gas flow changes, thereby maintaining a constant 80% combustion efficiency over the entire gas-firing range of the unit.

Combination packages that include both exhaust and supply fans mounted on a single roof curb are also available; please contact your sales representative for more information.

Electric Heat Coils are used in modular housings or in ductwork applications. Electric heat coils are used for tempering make-up air for installations requiring frequent air changes. The units are rated up to 257KW with voltages and phases to meet all electrical requirements. Air volume range is 400 – 22,000 CFM and up to 3″ wg @ standard air density, depending on the heating requirements. The heaters are intended for indoor or outdoor installations in commercial kitchens, factories, foundries and similar commercial and industrial occupancies.

Uniform steam distribution to each of the coil core tubes is accomplished by proper header assembly design. The steam supply connection should be located in the center of the header, with a perforated plate type baffle located directly behind this connection. Properly sized orifices are located in each of the core tube entrances into the header.

Coils are “freeze resistant”, also known as the dual-tube design. It is important to note that any steam coil can freeze when exposed to freezing temperatures without the proper drainage of the condensate! This coil design utilizes a smaller inner tube, with precisely spaced, directional, orifice type perforations. This is to help direct condensate flow to the return header.
