The good and bad of this brand, should look at the specific customer feedback, it just so happens that you said Shanghai Huizhuo, we hydrogen industry in use, the effect is not bad, ready to 2 period also on. This equipment has air-cooled and water-cooled two kinds. When choosing the need to pay attention to: important indicators to consider when looking for an industrial chiller, including the entire life cycle cost, power supply, cooling IP rating, chiller cooling capacity, evaporation capacity, evaporation materials, evaporator, condenser materials, capacitor capacity, ambient temperature, type of fan motors, noise level, internal piping materials, number of compressors, type of compressor, the circuit of the refrigerator, coolant requirements, number of fluid exhaust temperatures. For medium to large units should range from 3.5-7.0 high values to mean higher efficiencies. Chiller efficiency is often specified in tons of cooling per kilowatt (kW/round trip). Process pump specifications are important considerations including process flow, process pressure pump material, rubber, mechanical shaft seal material, motor voltage, motor electrical class, motor and pump IP rating. Chillers are priced at roughly $10,000 to $20,000 each, with cheaper ones costing a few thousand dollars and more expensive ones costing tens of thousands of dollars.
