YUHUA PRE-HEATERALWAYS THE RIGHT ANSWER
Have to stay in the iced-up car to start and idle the engine to warm up the engine block and cab inside for over 15 minutes everyday in the cold winter? How much fuel cost would waste during the cold season? How much more maintenance cost would occur due to the engine’s additional wearing during the cold season year and year?
Frost or icicles on car glasses blocked your eyes from the landscape in the cold winter? How dangerous it is to the driver and the passengers? Want to keep the car window free of ice and do not fog up?
Want to provide pleasant comfortable warmth in the mobile workplaces for the employees? Then, they will be always ready and get down to work.
Want to provide comfortable temperature to the passenger compartment in your Van, bus or marine boat? Customers’ satisfaction is the best advertising for your business.
Want to provide an optimum warm environment to your transporter’s compartment for the sensitive cargos? Yes, it is a must.
Need to provide an optimum temperature to your special-purpose vehicle to ensure the equipments inside will work normally and staffs work comfortably inside?
The trailer’s driver needs to have a good sleep for over 8 hours in the cold night? Then, the comfortable warmth is necessary.
Want to preheat your vehicle fleets’ engine when you’re still at home or in your living room before they start working? What a big saving comparing to idle the main engine just to warm up its block to reach a working condition!
You’re still using electric heater to take power from the locomotive/train’s batteries to defrost the fog or ice on the window and warm up the locomotive cab in cold weather? The electric heater is too low efficient, and the electric heater is dependent of power supply.
Agree to adopt the green technologies to protect the environment? Yes, I do, because we have only one earth!
YUHUA gasoline/diesel fueled series Pre-heaters would be the perfect solution for all the above requirements. YUHUA pre-heater would be your smart and must choice!

HOW THE YUHUA AIR HEATER WORKS
Combustion air from the environment and fuel from the
vehicle tank are mixed and ignited in the combustion
chamber. Fresh or re-circulated air is heated by the thermal
energy and fed into the interior.

HOW THE YUHUA WATER HEATER WORKS
Combustion air from the environment and fuel from the vehicle tank are mixed and ignited in the combustion chamber. The water heater is connected with the vehicle’s engine radiator, coolant from the engine is heated by the heater and circulated in the engine’s cooling system, thus, the engine is warmed up while the engine is off, this make it very easy to start the engine in a very cold day in winter. Meanwhile, perfect warm air will be fed into the cabin interior once you start the A/C (warm blower).
