The precision air conditioners , also known as a CCU (close control units) or CRAC (computer room air conditioner) are refrigerating equipment specifically designed to provide precise control of temperature and humidity in all applications in which is required a very high degree of precision. The precision air conditioners are used in data centers, where the refrigeration loads required can vary from 5 to 20 kW, server rooms, data centers, mobile, laboratories and many other industrial applications

For a data center to maintain its efficiency, the cooling requirements must be met. Temperature limits are a critical consideration when designing a data center because they can cause serious server issues. Servers may not operate well when the temperature is too hot or too cold. The environment must be right for optimal performance. Furthermore, if the data center ends up generating too much heat, it could result in extremely high utility bills for the facility. Having proper cooling systems will not only allow you to ensure optimal performance of your servers but also minimize on the energy costs of the facility.
