THERMOSTAT IMMERSION HEATERS Immersion heater with a thermostat which regulates heater’s operating hours. BENEFITS • Saves money by reducing electrical costs since the engine heater cycle time is reduced • Ensures engine start up since desired temperatures are maintained • Accommodates trucks entering or departing the bay since no preset timer is required • Efficient heater operation because the thermostat measures the coolant temperature rather than ambient air • Cost saving can be realized away from home base since the system stays on-board the truck HERE’S HOW IT WORKS TEST DATA The thermostat regulates the engine heaters by controlling coolant temperatures. The heater is cycled on and off according to temperature range settings. This ensures that a fleet owner or manager can control electric costs whether the truck is parked in the bay or on the road. • Tests were conducted across North America from extremely cold climates to moderate climates. The results reveal that the thermostat system reduces heater operating hours and electrical costs in the cold weather months.
