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