Industrial compressors are machines that increase the pressure of gases by reducing their volume. They are commonly used in various industries, including manufacturing, refrigeration, and air conditioning, to power tools, transport gases, and maintain equipment efficiency. These compressors come in different types, such as reciprocating, screw, and centrifugal, each suited for specific applications. They play a crucial role in processes like pneumatics, where compressed air is used to operate machinery, and in HVAC systems, where they help circulate refrigerants for temperature control.
