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.
