The line of unitized, low-intensity gas-fired infrared tube heaters has been expanded to 19 different heaters in more than 100 configurations. The new ETS/ETU Series tube heaters now range in capacity from 40,000 to 250,000 Btuh and are available in both natural gas and propane gas models. These heaters feature a totally enclosed, heavy-duty, pull-through draft inducer, which pulls combustion products through the calorized aluminized steel combustion chamber for increased radiant efficiency and greater safety, the manufacturer states. The draft inducer can be rotated 45 degrees or 90 degrees for sidewall venting. Individual reflectors can be rotated 45 degrees to direct heat where needed. End, corner, side, and U-bend reflectors are optional.
