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: Wide application of industrial water chiller
1. Water chiller used in the cooling of plastic processing mechanical molding mold which can greatly improve the surface finish of plastic products, reduce the surface striation and internal stress of plastic products, and make the products not shrink or deform. It is convenient for demoulding of plastic products and accelerating the finalization of products, thus greatly improving the production efficiency of plastic molding machine.
2. Water chiller is applied to the lubrication of the spindle of CNC machine tools, coordinate boring machines, grinding machines, machining centers, modular machine tools and all kinds of industrial precision machine tools and the cooling of the transmission medium of the hydraulic system, which can accurately control the oil temperature, effectively reduce the thermal deformation of the machine tools and improve the machining accuracy.
