    Shipping Way of ATO Water Chiller

    Just confirm us the shipping way by email when place your order.

    1. Ship by Air: The compressed refrigerant inside the chiller is a dangerous item with the possibility of explosion, so it needs to release the compressed refrigerant before transportation. (It means that water chiller without refrigerant when choosing this shiping way. After the machine arrives at your destination, you need to add refrigerant by local professionals, the process is as simple as adding refrigerant for ordinary air conditioners.) Delivery time is about 15-30 days.

    2. Ship by Sea: The transportation time is longer (about 40-55 days), and there is no need to add refrigerant after the equipment arrives at the destination.


    1. The "cooling capacity" is tested based on: Inlet and outlet water temperature of freezing is 12℃/7℃, and the inlet and outlet water temperature of cooling is 30℃/35℃.

    2. Working temperature range: Chilled water temperature range is 5℃-35℃, inlet and outlet water temperature difference is 3℃-8℃, condensation temperature not higher than 35℃.

    3. Conversion of units: 1 ton cooling capacity=3024kcal/hr, 1kcal/hr=3.969BTU/hr, 1HP=0.735kW=2580kcal/hr

    Tips: Difference between air-cooled chiller and water-cooled chiller?

    Industrial chillers are divided into water-cooled industrial chillers and air-cooled industrial chillers. The difference between them is mainly due to the difference of condenser. The condenser of water-cooled chiller takes away heat mainly through circulating cooling water, so the condenser of water-cooled chiller is also commonly called water cannon. Different from the water-cooled type, the air-cooled industrial chiller uses fan as heat sink. Generally, the fin type condenser is used. The fin actually refers to the aluminum sheet. The aluminum sheet is installed outside the part requiring heat exchange to achieve efficient heat dissipation, and then the hot air is extracted by a powerful fan.

    Therefore, when the workshop temperature is high, the air-cooled chiller will not only be affected by itself (the high temperature of the condenser will directly lead to the high pressure alarm of the industrial chiller, and the cooling capacity will decline), but also have a direct impact on the workshop temperature. The water-cooled industrial chiller needs circulating cooling water from cooling tower to cool down, so it is rather complicated to install cooling tower, cooling water circulating pump and pipeline to use the water-cooled chiller. Comparatively speaking, the air-cooled industrial chiller can be easily moved.
