The HLN Aquano 5K coolant heaters can reduce the engine friction during the engine’s normal operations. In the cold weathers, the engine lubricant temperature can be lower than the optimal operating temperature range. It is particularly true if your vehicle has to idle most of the time to wait for the next task. With the improvement in efficiency of the modern engines, residual heat from the combustion reduces. Together with the low temperature environment and reduced load, the coolant / lubricant temperature can drop to below 60°C. If it happens, the viscosity of the lubricant would increase significantly compared to if it were operating at 90°C. As a result, more fuel would be consumed to keep the engine running. With the help of HLN Aquano 5K heaters, the engine can operate under a much more fuel-efficient condition, saving your fuel cost and protect your engine in a long run.


The HLN Aquano coolant heaters preheat the engines in cold weathers to reduce engine wear at the starting stage. At the initial engine starting stage, there is no lubricant on the engine cylinder bore and pistons. Low temperature causes lubricant to increase in viscosity, causing it hard to splash lubricant on to the engine cylinder or pistons. With HLN coolant heaters, the lubricant becomes warm before the engine starts, making the entire cylinder – piston system better lubricated and protected at the engine starting stage. Thus, engine wear reduces significantly and long-term vehicle maintenance cost also reduced.


Coolant heaters can heat cars without external power supply and it does not need to start to idle hot cars in winter.Heaters have its own water pump and oil pump.And they are installed between engine and ceramic heater’s tank.The electricity comes from vehicle battery.Then the oil pump lights after it extract a little fuel from oil tank which atomize in combustion chamber.It heat antifreeze by heater exchange system and circularly output to the engine. Making the engine and warm air blower’s temperature get higher gradually.When the temperature reaches 65 degrees,heaters will automatic stop and the remote will display that you have finished heating. This kind of heaters can be used in the heating equipment of the car and can not conflict with another devices.
