Infrared Radiant Heating for Commercial / Industrial Applications

commercial / industrial > products > tube heater - ets / etu series

These series, with more than 80 different configurations and in capacities from 40,000 to 250,000 Btu/hr, offer optimum flexibility in custom designing an infrared heating system.

The ETS series is available in multiple configurations (straight, L, Z, and expanded U-shape) with lengths from 15' to 80' long. For added versatility, 90° elbows, corner reflectors, and side reflectors are available for close area mounting near walls, doors, and corners.

The ETU series is available in seven different configurations and provides more uniform radiant heat energy distribution. The ETU series is ideal for high heat loss areas and spot heating.

NOTE: The clearances specified above must be maintained to combustibles and other materials that may be damaged by temperatures 90ºF above ambient temperature. Clearances to combustibles are posted on the reflector near the control end of the heater. In locations used for storage of combustible materials where they may be stacked below the heater, NFPA 54 requires that the installer must post signs that will "specify the maximum permissible stacking height to maintain the required clearances from the heater to combustibles".

* When used indirect vented, the clearance to the ceiling from the top of the exhaust hood must be 12" for ETS/U40--ETS/U75, 18" for ETS/U80--ETS/U175, and 24" for ETS/U180--ETS/U250. If optional corner or U-bend reflectors are not used, clearance must be 18" (24" for ETS/U180--250).

** 72" clearance 20’ downstream from the Control Box

NOTE: Consult the factory if reduced clearances are required. Also, please note that this heater is NOT for residential use.
