VARISTAR LHX 20/40 series is based on air/water cooling system operating on the principle of horizontal circulation. These cabinets are based on VARISTAR cabinets equipped with air/water heat exchanger LHX20 with the capacity of 20 kW or LHX40 with the capacity of 40 kW. This system is designed for high-performance applications during which large amounts of heat are created; at the same time, operation of the system does not depend on the ambient conditions in the room where the whole system is to be located. LHX20/40 heat exchanger is mounted on the side panel of the cabinet or on left or right cabinet with the height of 800 mm, creating complete system. In addition, it is possible to combine two cabinets side-by-side, and LHX20 heat exchanger can then cool several cabinets combined in this way. With a width of 800 mm and lateral location of the heat exchanger, 19” plane can be used on its entire height of 42 U in the cabinet. The cooling system has its own housing and consists of heat exchanger, moisture absorber, 6 fans, three-way valve and control unit with a display.Thanks to high air flow rate and lateral location, equipped with six independent high-performance fans (which can be replaced individually, even during system operation in the event of failure of one or more of them), the heat exchanger cools the modules installed along the entire height of the cabinet very well. There is no water vapour condensation under normal operating conditions. However, it is possible if, for instance, the cabinet door was open for a longer time. In this case, a suitable system is activated and the generated moisture is collected in a special absorber and then removed outside the cabinet through a special tube. Thanks to the modified support frame, the cabinet has a static load-carrying capacity of up to 1000 kg. The cabinet dimensions are: height – 42 U, width – 800 mm and depth – 1200 mm. The cabinets are available in a single and double door version – front door is only available in the glazed version (rear is closed by plain steel door with a maximum opening angle of 180°). The cooling capacity of the applied air/water heat exchanger is 20/40 kW while maintaining a very low noise level of 50.7 dB(A) (when fans operate with a capacity of 80%). Cabinets are only available in the standard colour RAL7021. Degree of protection IP55.
