Proheat X45 Plus
Powerful and Rugged Auxiliary Coolant Heater
for Coaches

Proheat X45 Plus is a powerful, diesel-powered pre-heating solution for quick and reliable cold weather starting of coaches. This versatile heater becomes part of the coach heating system, supplying added heat for the driver and passengers while reducing fuel costs and emissions from unnecessary idling. Proheat X45 Plus also makes starting easier while reducing start-up engine wear and cold weather troubles. An integrated pump circulates heated coolant to warm the engine block. Proheat X45 Plus features an onboard control panel that displays heater status, while an optional digital timer can mount next to the driver seat 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.
