1.This product is suitable in the explosive atmospheres of chemistry, marine drilling platform, metallurgy, medicine, light industry,textile, foodstuff, biological engineering, aerospace engineering, war industry, etc. And 3phase 4wire system (380V/220V)Acdistribution system and all light current system.
2.Hazardous:division 1 &2
3.Explosive gas atmosphers:class ⅡA ⅡB ⅡC or inflammable dust environment;
4.Indoor or outdoor(IP65,IP66*);
5.Temperature class:T1~T4;
5.Widely using in the fields of oil, chemical industry, spaceflight, war ind-ustru and so on.
1. The principle adopts medium isolating ignition to avoid explosion of electrical equipments;
2. The products can be fixed with inspection meter, analysis meter, vision meter, monitor, Micro-computer touch screen,highpower transdducer and other electric components, the inside components are unlimited;
3. It is composed of board, body automatic control system, air arrangement ayatem, alarm system and distrbution systen, thebody is composed of positive pressure chanmber and subsidiary chamber, there is a self-control system, alarm system andcable in the subsidary chamber, other distribution system components are in the positive pressure chamber;
4. There are box style, musical plate style and board style, the board style are divided into fluctuated structure and right andleft structure. For the box style, the body is welded by steel plate and sprayed with plastic, operated through the front doorthe board shelf of musical plate and board style is welded by standard profiled bar, surface is sprayed with plastic, the jointplane is handled with sealing, treatment operating from frontal door and maintaining from back door, Normally we selectGB710-88 cold cast steel, also can select GB3280-84 stainless;
5. There are ventilation and compensation entry ways, ventilation entry is used for continue air feed, the heat in pressurechamber can be sent out. It's also with good heat diffusing function, the compensation entry is for dos continuity air feed,the prsee chamber is with perfact sealing and low gas comsumption functions;
6. The user must supply clear air or nitrogen, gas pressure: 02.Mpa~0.8MPa, satisfy the locale requirement, we can designthe gas supply system on request.
