There are PQ series, M series, and CRV series. Each with its own characteristics could be used in different places.Blade series is applicable for the server (horizontal blower type) with a surrounding air inlet and split system. It can meet the needs of a new generation of computer room and server center refrigeration standard. The refrigeration density for the blade series is very high (on the surface of 0.8mm2 reaches as high as 25KW). By using the modularized design including adaptive logic system can be managed through network, and the blade series is the best partner for the architecture of blade server and high density equipment. It is the ideal refrigeration system for the telephone, internet, data center, service center, and high density of buildings.
