Chiller equipment is one of the most widely used pieces of machines in the modern business world. But what exactly is a chiller and what does it do? To put it simply, chillers are machines that work to cool or freeze air, water, liquids and other materials for industrial and commercial applications. At their core, chillers have several interconnected components – compressors, evaporators and condensers – that remove heat from a building, product or process by running a refrigerant through its system. By providing cooling solutions, chillers are an essential part of many businesses’ operations. From temperature control for industrial machinery to keeping chilled food products fresh, chillers are an invaluable asset for successful enterprises.
