HWP series forced circulation water engine heater is composed of 3 parts: control section, water pump and water heater.
If during cranking the outside temperature is lower than 4ºC, engine coolant and lubricant may condense into solid state and lose their lubricating and cooling properties, which can damage the engine. Engine heater should be installed to ensure normal starting and running of the engine when the outside temperature is lower than 4 ºC.
HWP series forced circulation water engine heater combines the following features: cast stainless steel inner pipes and end closure with high corrosion resistance; heating and overheat light indicators; user-defined thermostat set point; dry heating and overheat protection.
This product is suitable for various engine with (15~100)L displacement.
PERFORMANCE AND CHARACTERISTICS:
1. The circulating water pump adopts special customized pump with stainless steel pump head for good mute effect, reliable and safe and long lifetime.
2. Control section: microprocessor design; high sampling precision and accuracy control due to PT100 temperature sampling. Coolant temperature can be set via the control panel. Four digital LED display, coolant temperature and all kinds of set point temperature can be displayed clearly.
3. Dry heating and overheat protection.
4. Separately control of water pump and water heater: power on the water pump and water heater synchronously, once the set temperature has reached, water heater will be powered off firstly, after 3s, following is water pump. The goal is to prevent heat concentration and significantly prolong water pump lifetime.
5. Manual test: test the water heater and water pump are normally or not via panel button.
6. Fine cast aluminum enclosure and special surface treatment with high corrosion resistance and high/low temperature capability;
7. Stainless steel inner pipes and end closure with high corrosion resistance;
8. There is a water drain valve with seal ring on the bottom of the heater so as to be used when needed;
9. There is one-way inlet valve on the water inlet.
10. This product can work normally at -25℃ temperature.
