air to air heat exchanger

Yanxiang Electronic’s heat exchangers are temperature regulating equipments specially designed for installing on various types of communication and network cabinets or base stations. Using the heat exchange system with internal and external heat circulation effectively isolated, the equipment controls automatically according to preset modes, forming effective air circulation inside the cabinet which realizes dissipation of heat accumulated. The heat exchanger can ensure the inside of the cabinet is clean and not polluted by external air, and meanwhile allow the equipment work normally within constant temperature and humidity range, so that it can regulate temperature to the greatest extent and reduce energy consumption. Features: (1) Energy-efficient, intelligent control according to real temperature situation of internal and external circulation, reducing energy consumption to the greatest extent. (2) Environment-friendly, conforming to RoHS standard, low noise, no emission (3) High protection level (IP 55), for outdoor use (-40 65 ºc,-40 – 155 °F) (4) High air flow volume, , make sure overall heat transfer inside the protected equipment (5) Simple and convenient installation (6) High reliability, maintenance free (7) Custom design (8) With multiple patent designs and technologies Application: Communication, Electronics, wireless networks, mobile telecom base station, monitoring station, transmission equipment, communication equipment, computer, frequency converter, voltage transformer, switch equipment, automatic control equipment, high voltage control cabinet, cable TV equipment, machine tool power supply and control equipment, instrument laying rack/cabinet.
