HVAC chillers can come with a local or a remote-control panel, which also indicates the chiller‘s pressure and temperature. Some HVAC models include emergency alarms, an integral pump and microprocessor controls. Some models are designed to be used only indoors while others are specifically designed for outdoor use and can be mounted on building exteriors or rooftops. Modular systems are also available and can be configured in various ways depending on the requirements of the application.
HVAC chillers can be used to pump water to coils in different parts of an industrial plant or building. They can also be used to cool plastics, laser cutting machines, printing equipment, or large-scale medical devices such as MRIs and CT scans. to the method they use to move the fluid: direct lift, displacement, and gravity pumps. Pumps must have a mechanism which operates them, and consume energy to perform mechanical work by moving the fluid. The activating mechanism is often reciprocating or rotary
