SunStar® Infrared Tube Heater - SIU Series - 75,000 BTU - 20' Tube
More about SunStar® Infrared Tube Heater - SIU Series - 75,000 BTU - 20' Tube
The perfect heater for hard-to-heat spaces like your warehouse or garage, the SunStar 75,000 BTU SIU Series Infrared Tube Heater with a 20' long tube provides both the fuel efficiency of radiant heat and the installation flexibility you need. This Tough Guy heater features an emitter tube perfect for high humidity/corrosive environments such as dairy barns, swimming pools, greenhouses, or water treatment plants.
The SIU Series of Infrared Tube Heaters from SunStar give you the same options you like from the SIS Series, but at a shorter length. The tube is bent in a U shape, so a 50' tube heater only measures 27'9" long.
