A stationary chiller is a chiller that does not have a pump or tank directly attached to it. The basic composition of a stationary chiller is a single chiller unit that stands alone. A connection from pipes to pump and a separate water reservoir are required in order for the stationary chiller to properly function.  A stationary chiller can be small or large, ranging from two tons to possibly more than 250 tons.

Typically, the stationary chiller system utilizes separate controls for the chiller itself and the pump or pumps it is connected to through piping. Each component has an electrical connection. In addition, the controls should be wired properly together. Proper wiring prevents the chiller from cooling before the circulating pump is up and running. If the chiller begins to cool before the circulating pump is on it could cause detrimental effects to the chiller. This could create a costly repair bill.

Stationary chillers are also known as central chillers. This means that the cooling happens centrally in the chiller and then is dispersed through piping. This can happen with single, dual or multiple pumps that pump water and compress refrigerants. Stationary chillers can be installed indoors or outdoors depending on the application for which it is intended. They can be used residentially, commercially and industrially. Stationary chillers can be air cooled through the use of ambient air or water cooled. Since stationary chillers are not a “one size fits all” product they can be custom made for companies and their specific application. This accommodation allows for companies to maximize their return on investment and turn a profit.

Chillers are used to remove heat from liquids and release it into the atmosphere through the process of refrigeration. They are used to cool process equipment, air or another liquid. They can be very large or very small and used for a multitude of applications.
