Maximum Freeze Protection

Heat King® is the highest capacity dedicated transport heater available in the market today. Heat King delivers maximum uptime, ease of maintenance and long-term reliability with its heavy duty, rugged and simple design. The heart of the unit is a heavy-duty diesel engine which heats coolant that flows to a radiator inside the cargo space, where a high-capacity blower moves the heat throughout, keeping transported products above freezing in the coldest conditions.
