In business, a condensing unit is a self-contained mechanical appliance that compresses and cools a gas to provide cooling services. It aggregates components like the compressor, condenser, expansion valve, fan, and receiver in one metallic case for maximum efficiency. Depending on the particular application and product involved, condensing units can come with additional components like interconnecting piping, additional valves, and filters. The use of condensing units allows for more flexibility in the design of cooling systems since these units can fit into any kind of environment, and they are easy to maintain and replacable. Regardless of where they are used, all customers can benefit from their efficient, cost-effective operation.
