    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: 4 reasons for noise of industrial water chiller

    1. Compressor noise

    In the internal structure of the precision water chiller, the compressor is the core position of the chiller. Generally speaking, the compressor has two types: Scroll type and screw type. Once the compressor makes noise, first check whether the expansion valve is excessively opened, and then adjust it a little bit when it is opened. Next, check whether there is too much refrigerant. If it exceeds the limited range, remember to eliminate the redundant refrigeration agent.

    2. Noise of water pump

    Once the water pump makes noise, it is basically that the water quality is in question. The water quality shall be treated according to the requirements of the corresponding chiller.

    3. Lack of lubrication for accessories

    Most of the water chiller configurations are made of metal. Once the parts are lack of lubrication, there will be some friction and noise. In addition, we should also pay attention to maintenance at ordinary times, so that there will be fewer failures.

    4. Overload and oil shortage

    Once there is noise, check whether the compressor is short of oil. If it is found out, make up the oil immediately. Check the load of the compressor in time. If there is any problem, solve it in time.
