Low-temp Circulating Chiller

Laboratory chillers are currently on sale, with the favorable price and intimate service.

What is a Chiller?

A chiller can be regarded a cooling system that cools materials down by removing heat from a liquid via a vapor-compression or absorption refrigeration cycle. The liquid gets circulated through a heat exchanger to cool equipment. In a chiller system, there is always a liquid working as a refrigerant going through the heat exchanger in order to transfer the heat energy. When the heat gets absorbed by the liquid, materials get chilled.

A complete chiller is basically composed of the following components: a condenser, a compressor, an evaporator, an expansion valve, a power unit, water boxes and a control unit. The condenser can remove heat from the refrigerant, including air and water cooled condensers.

What are the Types of Chillers?

There are three major types of chillers in use based on the condenser type, which are air-cooled chillers, water-cooled chillers and evaporative condensed chillers. As their name suggests, the air-cooled chillers use air to remove heat in the condenser by using fans to force air across the exposed tubes of the condenser. While the water-cooled chillers use water to remove heat by using pumps to send water through a sealed condenser. The latter is generally more energy-efficient than air-cooled chillers. The evaporative condensed chillers can condense a substance from its gas state to its liquid state by cooling it. Then the heat is released by the substance and transferred to the surrounding environment. It is usually considered as an alternative device to air or water cooled chillers.
