The generator set spray box belongs to
cooling system
, and its maintenance should pay attention to the following aspects (if you want to find one, please find one generator set maintenance company to maintain it instead of
p>Water treatment company
): A. Water quality requirements
p>Be sure to use clean water that meets the requirements of ASTM D4985. If this requirement is not met, the cooling system may be blocked, resulting in a reduction in the cooling effect. If the water quality does not meet these requirements, distilled water or coolant should be used. Total

Coolant Replacement: The coolant used in the cooling system must be able to protect the engine interior from corrosion and icing (if the climate requires it). Never use water alone. The efficiency of the coolant will decrease after a while. Therefore, the coolant must be replaced. As long as you follow FDI Kang's coolant recommendations, you can adopt the following replacement cycle. Coolant change intervals Coolant (glycol mixture) and coolant filter every 4 years or at least every 10,000 hours Coolant (glycol mixture) without coolant filter Every year or at least least every 5,000 hours Anti-corrosion agent Every year a. The systemcooling me must be rinsed. When replacing the coolant, do not replace the coolant filter (accessory). The coolant filter should be replaced 6 months after the first coolant replacement, then every 6 months. b. If there is a risk of freezing, use a mixture of 50% antifreeze and 50% pure water. Mix the glycol and water in a separate container before adding the mixture to the system; there is never any risk of frost. Use a mixture of water and preservative as a coolant. The mixing ratio is 1:30. After adding the coolant, allow the engine to run at operating temperature, which can maximize the effectiveness of the additive. If the annual operating time exceeds 500 hours, 1/2 liter of anti-corrosion agent should be added to the coolant every 500 hours. However, whatever the climate, we reorder to use a coolant mixture of ethylene glycol and purified water all year round. vs. Except in an emergency, do not open the water filler cap while the engine temperature is still very high. Otherwise, steam may escape. Check the coolant level daily before starting the engine and add more if necessary. The coolant level should be lower than the sealing surface of the water filler cap.5CM. If a split expansion tank is installed, add between the MIN and MAX marks. Notice! When adding, use the same coolant as the original coolant in the cooling system. Notice! Never mix antifreeze (ethylene glycol) and corrosion inhibitors. Mixing these two substances will create foam and significantly reduce the effectiveness of the coolant. Notice! Rfill the drained cooling system with coolant. Notice! Additives are harmful to the human body, please pay attention to safety when handling.
