Explosion Proof Pressurized HVAC

• This explosion proof HVAC is used for process analyzer shelters, analyzer houses,it can provide positive pressure air into the shelter, so it is also called explosion proof positive air conditioner.This explosion proof air conditioning system can keep the room’s air pressure higher than the outside air ,this can stop the outside dangerous air entering into the room,keeping the workers safe in inside the room.

• This type explosion prof HVAC units are designed to provide cooling, heating, pressurization, fresh air purging in one assembly. They are typically furnished for instrument control room, laboratory, measuring room, analyzer shelter etc in hazardous locations.

•  Case material:Carbon steel with corrosion-proof painting, Stainless steel (304 or 316).

• Customized alarm or control functions intend for meet control of analyzer shelter

• Copper tube copper finned coils, corrosion protection coating coils,Stream heating coils

• Full redundant heating, ventilation, air conditioning combined into single package is available

• Remote control interface is available.

• Medium efficiency particulate air filter, HEPA filter..

• This type of explosion proof HVAC is up to the standards of the products quality surveillance of national explosion-proof electrification, and has obtained the explosion proof certificate . Such explosion proof split wall mount air conditioners can be used in Used in the hazard area:

       Zone 1,Zone 2 ,Groups IIA,IIB,IIC (IEC hazard area classification),

Suitable used in the temperature range: T1,T2,T3,T4

Explosion-proof mark : Exdmbib Ⅱ BT4, Exdmbib Ⅱ CT4  .Explosion proof protection can be designed according to the ambient environment.

This explosion Proof air conditioning and air ventilating system is produced based on the explosion proof equipment standards as below:
