Knowledge and purification device using a safety test Wei a central air conditioning disinfection purification device) Power: Quote passenger compartment supply; b) Wiring: using connector type, easy accessibility; c) Safety: In the original back the throttle to increase the junction box 1P open space to prevent short circuits. d) work: As long as there is electricity, electrostatic dust removal device that is working. e) Working indicator: lights installed at the top of the throttle back. f) Recoverability: With plug sealed junction box plus open wiring hole to restore the original state. 5. The cleaning device safety tests u dry test: detecting the operating current, the work frame no leakage; u unit rain test: Test the rain when the rain after the device to work properly; u spray test: the device work When its fine water spray, it works fine; u simulation plush test: medication cotton plush fiber paste to live positive and negative cylindrical tip, such as positive and negative communication hospitals duct air purification devices, dry the device It can work, after a short-circuit water pipe air purification systems offer, stop working. Go dehumidification cotton, re-energized, it can work normally. Dongguan City Environmental Technology Co., Ltd. is an industrial area, Dongguan major support of high-tech R & D-oriented manufacturing enterprises, the new factory is located in Dongguan City Changan Wu Sha Hong Road on the 5th Village. Strong technical force, in the central air conditioning disinfection purification and environmentally friendly energy technologies has a number of patents; personnel with experts, engineers plus the exchange of scholars echelon configuration, in order to lead into the R & D, manufacturing, sales and construction as one of the new environmental protection equipment development companies. First, the central air-conditioning duct food, pharmaceutical and cosmetics factory pipeline disinfection purification equipment air purification systems, use of new technologies to meet the bid for the manufacture of customized health permits, QS, HACCP, 高标准 and other air quality standard equipment; Second, the use of the new return air mixing section to install permanent disinfection purification devices operating efficiency, achieve clean air pollution, blocking transmission of the virus hotel duct air purification systems, reducing air conditioning pipe wall dust accumulation; three new rural environmental protection equipment, professional farms, raising farms and other customized equipment sterilization in addition to taste, to solve the "how much pollution is the farm," the environmental problem fundamentally, the barrier effectively kill various types of infectious diseases (such as avian influenza, plague), gaseous organic pollutants. 300 kinds of indoor decomposition of gaseous pollutants, respirable particles, and a variety of bacteria, viruses. Various odor and particulates within the air due to the exclusion of decoration, including cigarette smoke, etc., protect people's health. Identified expert committee of the disinfection purification technology company in the world leading level.
