Proheat X45 is a powerful, diesel-powered school bus pre-heating solution for quick and reliable cold weather starting. The heater becomes part of the school bus heating system, supplying added heat for passengers while reducing fuel costs and emissions from unnecessary engine idling. An integrated pump circulates heated coolant to warm the engine block, making starting easier while reducing start-up engine wear. Proheat X45 features an onboard control panel that displays heater status, while an optional digital timer for inside the bus adds convenient timer-based starting of the heater. The heater also complies with National Highway Traffic Administration standards to ensure maximum safety for bus passengers. With more than 15 years in the field, its rugged and field serviceable design has proven reliable in even the most extreme temperatures.
