HWP30N is smart forced circulation water heater of engine. When 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.
It has lamp indication function, which can indicate all kinds of heater statuses. Heating temperature can be set by users, and dry burning prevention and overheating protection are fitted.
PERFORMANCE AND CHARACTERISTICS
Micro-processor design is applied for the control part, precise temperature sampling, heating temperature can be set from control panel.
4-bit digital tube display is applied, which can display current coolant temperature, user defined temperature, accumulated running time, accumulated energy consumption, current voltage parameters etc.
Water flow sensor is fitted, which can quickly detect shortage of water, pipe gas gathering, pipe clog, in order to prevent heater from dry burning, gas gathering etc. unhealthy phenomenon.
Circulation pump and heater are controlled separately; water pump is firstly started before heating, and then heater starts after delay for 5s; when it reaches pre-set temperature point, heater power is disconnected immediately; then water pump power is cut off after delay for 60s; this is to prevent heat gathering so that it can prolong pump life.
Manual test function is fitted, which can check whether heating body and water pump is able to operate normally through panel button.
Fine cast aluminum material is used for heater shell.
Stainless steel inner heating pipes.
Water drain valve is fitted at the bottom of the heating body, which can be used on demand.
This product can work normally at -40℃ temperature.
