Use and maintenance of hot and cold water coils 1. The maximum working pressure of the coil is 20kg, the normal water supply pressure is 2~4kg, and the overpressure operation is cut off; 2. In areas where winter freezes, the surface cooler should be emptied before winter comes, and the hot water coil should also be emptied during shutdown to prevent the coil from freezing and cracking; 3. Be sure to set a filter on the inlet pipe of the coil. If the coil is seriously blocked by debris, the cooling capacity will be significantly reduced, and the coil needs to be replaced; 4. After the hot and cold water coil is used for a period of time, there will be a layer of dust on its surface, which reduces the heat transfer coefficient. Please be sure to clean it regularly; Drain pipe precautions 1. The water trap should be insulated, otherwise there will be a lot of condensation; 2. The condensate drainage pipe must have a certain slope, otherwise it will lead to poor drainage; 3. The unit should make a suitable water trap, otherwise it will lead to poor drainage in the negative pressure section; 4. If there is water in the unit, please first confirm whether the condensate pipe is unblocked; Pump Operation Check 1. Whether the three-phase current of the water pump is normal, there is no phase bias and overcurrent; 2. Whether the water pressure and water volume of the pump in operation meet the requirements; 3. The leakage of each valve shall be repaired or replaced in time; 4. Whether the water filter is blocked. Water pump failure and treatment 1. The water pump does not produce water, and the pointer of the pressure gauge jumps violently; (there is air in the pump body, the suction pipe leaks, and the pipeline is blocked) 2. There is water pressure but the water pump does not produce water; (the outlet pipe is blocked or the valve is not opened, reversed, and the speed is low) 3. The flow rate of the pump is too small; (siltation, impeller wear) 4. The water pump is overheated; (the lubricating oil is too little, the bea

Industrial evaporator coils are one of the most important accessories in most complete refrigeration systems. The condenser condenses the refrigerant gas inside the coil and completes the heat exchange coil. This evaporative condenser is widely used in refrigeration, freezer, chemical, supermarket, etc. Detailed product information: 1) Tube type: connecting tube 2) Thickness: 1.2mm for stainless steel. Hot dip galvanized is 1.5mm. Can also be designed according to customer requirements. 3) Test pressure: 25 bar. Both test pressure and design pressure can be carried out according to customer's requirements. Our tubes are designed as oval tubes, but not round tubes, with the following advantages: The oval tube can reduce the inner diameter of the heat exchange tube, enabling a tighter tube arrangement to increase the heat exchange area by 65%. The special oval tube ensures better access to the water on the outer surface of the tube. The form can also be made tighter, the fill rate of the liquid is reduced, and the air flow resistance is reduced. The working principle of the condenser coil: 1) The coil section rejects the heat evaporating through the fresh air, and on the other hand the sensitive thermal effect of the spray water through the pre-cooling cycle. 2) Reduced evaporative cooling effect helps reduce the possibility of scaling on the coil surface.
