These Pro-Tough propane forced-air heaters from Desa are equipped with a high-capacity fan to circulate directional heat. The newest model from this company integrates an adjustable-height footing to angle heat upwards for specific spot heating. The control panel is mounted on the top of the heater for easier operation and servicing. The company has also incorporated a roll-cage design that is manufactured to withstand hard use and harsh work environments. Molded plastic end-caps protect the heater if it is dropped or knocked over. The heaters are available in Btu outputs of 30 to 55,000, 50 to 85,000, 75 to 125,000, and 125,000 to 170,000.
