Product Overview:
HFW50 fuel auxiliary heating device is an intelligent fuel engine water heater. When the engine operation temperature is below 4ºC, engine liquid coolant/lubricating oil may be coagulated to solid state in starting phase and lose lubrication or cooling effects, so that it may damage the engine. Therefore, heater shall be installed for engine to ensure normal starting and running. This device is able to heat the coolant, when the heated coolant flows through the heat exchanger of the vehicle and heats up the space inside the unit. At the same time, the coolant also flows to the engine and heats it up. The preheated engine is capable of reaching the working temperature faster, so that the engine can go to normal running.
The OLED of the heater displays various parameters. The heating temperature can be set by users, and drying burning prevention, overheating protection and fault alarm functions are fitted
PERFORMANCE AND CHARACTERISCTICS
——Micro-processor design is applied, precise temperature sampling, the heating temperature can be set from control panel; operating mode, running phase, etc.;
——OLED display screen is applied, which can display the current water temperature, user defined temperature, accumulated running time, accumulated fuel consumption, current voltage,
——Circulation pump and heater are controlled separately; during heating, the water pump is firstly switched on, the heater starts after a delay for a period of time and enters the inertia phase when reaches to the setting temperature, the fuel pump is powered off first, then the water pump and fan will be powered off after a delay for a period of time, which prevents the heat concentration and extends usage life of the pump;
——Manual test function is fitted, which can force to work for 240s; check whether indicator, display screen and fuel pump are able to operate normally via panel button;
——Fine cast aluminum material is used for heater shell;
——Water drain valve is fitted at the bottom of the heater, which can be used on demand;
——This product can work normally at -40ºC environment.
