The Maxi-Heat portable heater is designed to eliminate the problems with moisture associated with direct-fired heaters. The enclosed twin heaters have a total output of 1,000,000 BTUs per hour and deliver a maximum of 5,600 cfm. Options include a lockable accessory/tool box and flexible ducting. A 191-gallon fuel tank permits unattended operation for more than 24 hours. A low-oil pressure, high-temperature shutdown system protects the engine from damage.
