Introduction to Chiller Unit
A chiller unit is a refrigeration system that removes heat from a liquid via a vapor – compression or absorption refrigeration cycle. This cooled liquid then circulates through a heat exchanger to cool equipment or other processes. Chiller units are widely used in various industries, including manufacturing, data centers, commercial buildings, and food and beverage processing. They play a crucial role in maintaining optimal temperature and humidity conditions, ensuring the smooth operation of equipment and the quality of products. Chiller Unit
