Unit-type coolant preheating and insulation system consisting of a pump, temperature sensor, and control panel [for 300L displacement engines].
The "CLM Coolant Heating System" is an integrated coolant preheating and insulation system consisting of a pump, PT-100 temperature sensor, and control unit. By forcibly circulating the coolant, it uniformly preheats and insulates the entire engine, improving the startability of the equipment and reducing the risk of engine wear, damage, and white smoke in low-temperature environments. The long lifespan of the heater element is also a notable feature. 【Features】 ■ Compatible with engines up to 300L displacement ■ Compliant with CE standards ■ Conforms to DNV maritime standards (design and testing) ■ DC 24V relay for automatic on/off ■ Remote monitoring connection available For more details, please refer to the catalog or feel free to contact us.
