Working Principle: The preheater uses a 220V power supply to circulate and heat the antifreeze through the built-in pump and electric heating element, increasing engine temperature. Multifunction: Improves interior temperature, preheats engine coolant, and helps prevent engine wear in cold conditions. Supports interior thawing, easier vehicle starting, and windshield defrosting. Fast Preheating: 1500W heater with built-in thermostat provides efficient heating in approximately 30 minutes, enabling reliable operation even in temperatures below -30°C. Wide Application: Suitable for cars, trucks, buses, campers, caravans, engineering vehicles, and marine vessels with engine displacement under 1.5L. Durable Construction: Metal housing ensures long-term durability with a service life of no less than 2000 hours. Easy installation saves time and effort, allowing convenient parking near home or office.
