Operational Principle: Indoor air becomes sterilized air by filter, photo-catalytic sterilizing and electro-static adsorption and then to calefaction antrum by fan. The air in calefaction antrum was heated forcibly to a scheduled temperature and later to a room to come into being a pressure difference to reach good xeransis and finally to medical dry cabinet to reach xeransis of instruments. Part of heated air imbibed the temperature of dew on the surface of instrument and increased the humidity of air to continue circulation and reduce quantity of heat expense. The other part of the heated air let out humid air to outdoor. The instruments are dried by this continuous circulation. Laoken medical dry cabinet makes use of SCM real-time high accuracy temperature and circulated wind controlling. The temperature and working time is displayed on LED screen simultaneously. The working temperature and time can be set manually according to different requirement. Product Description: The medical dry cabinet composed by filtration system, sterilization system, heating system, exhausting system. Laoken medical dry cabinet introduced into foreign high-tech and facilities, and invented by years of R&D from the technicians. The body adopts stainless steel and with remote controller to make operation convenient. Application scope: Xeransis for surgical instruments in hospitals and Health departments and it is especially an idealistic and high efficient equipment for glassware, stainless steel instruments and conduit)
