Most air-cooled chiller systems used in small refrigeration equipment repair, large units are mostly water-cooled. Water-cooled units in terms of investment is less than the air-cooled. Air-cooled chiller uses air cooling, eliminating the need for cooling water systems are essential to the cooling tower, cooling water pump and piping systems, the water quality is too poor areas to avoid causing condenser fouling, clogging pipes, but also save water resources, is Currently chiller equipment products, the maintenance of the most economical and simple models. Air-cooled chiller water-cooled chiller than a one-time investment to be slightly higher, but easy to manage. Is the product of choice for small systems.
