In our normal use, the maintenance of refrigerated trucks and refrigerators is inseparable. Only by performing proper maintenance and upkeep on the Lengwang refrigeration unit can the normal use of the equipment be ensured and the service life of the equipment be extended.

In general, the chassis engine is maintained based on mileage, while the refrigeration unit is maintained based on engine operating time. Under normal circumstances, the refrigeration unit should be maintained every 500-700 hours by replacing the oil filter, fuel filter, and air filter; Check the tightness of the belt and the leakage of the refrigeration system;

To meet energy-saving needs, some brands of refrigeration units use synthetic engine oil or semi synthetic engine oil instead of ordinary engine oil to reduce environmental damage and harmful substance emissions, in order to extend the maintenance time of the engine. Usually, maintenance is carried out every 2000 hours.

Therefore, the discharge of waste oil has been reduced. In addition, scientific experiments have shown that using this good oil can not only reduce engine wear, but also lower engine fuel consumption.
