Wacker Neuson Cub 300HD

Wacker Neuson added a larger fuel tank, beefier undercarriage and a removable center lifting bracket to create a heavy-duty version of its Cub 300 indirect fired heater. The Cub 300HD runs 26 hours at full load, and up to 50 hours when using the optional remote thermostat. Wacker Neuson says the heater's net efficiency is 81 percent with no open flame or combustion carbons or water. Maximum heat input is 302,000 Btu per hour. The fan produces  2,600 cubic feet of air flow per minute and can efficiently push heated air through flexible ducts for even site heating.
