Proheat X45 Plus
Powerful & Rugged Auxiliary Coolant Heater for
Off-Highway Equipment

Proheat X45 Plus is a powerful, diesel-powered pre-heating solution for quick and reliable cold weather starting of 12 or 24-volt construction, logging or mining equipment. This versatile heater can be used to pre-heat the engine or prevent freezing of critical onboard fluids. Proheat X45 Plus makes starting easier while reducing start-up engine wear and cold weather troubles. An integrated pump circulates heated coolant to warm the engine block, hydraulic fluid, fuel tank, or provide additional heat for operator comfort. Proheat X45 Plus features an onboard control panel that displays heater status, while an optional digital timer can mount next to the operator to provide convenient timer-based starting of the heater. With more than 15 years in the field, its rugged and field serviceable design has proven reliable in even the most extreme temperatures.
