Portable construction heater

The Safe Heat-500 portable construction heater from Topp Portable Air has a heating range between 100,000 to 500,000 BTU per hour while operating on a standard 120 volts. Safety features include a patented 100-percent stainless-steel burner with inner-lined heat shield that maintains a cool outer shell and a red indicator light located near the on/off switch to warn of potential problems. An enclosed, fan-cooled, industrial motor drives an eight-blade, high-efficiency axial propeller, and higher static pressures maintaining air movement. Large-diameter wheels and rubber-gripped handles are designed to provide easy handling and maximum portability of the SH-500.
