Brief introduction of explosion-proof units
The explosion-proof unit is a special air-conditioning equipment, and its components are manufactured in strict accordance with the relevant requirements of the national explosion-proof standard GB3836, and have obtained an explosion-proof certificate. It is suitable for use in flammable and explosive special dangerous places and general places. It is widely used in petroleum, chemical, textile, printing, medicine, food and many other industries.
H.Stars Explosion-proof Unit
According to the characteristics of the project, the explosion-proof type can be an explosion-proof type or a positive pressure type. Ex d IIB T4, Ex d IIC T4 can be selected for the explosion-proof grade, and other explosion-proof units can be customized according to user requirements.

Main components of explosion-proof unit
Explosion-proof compressor
The explosion-proof compressor is produced in accordance with the national standard GB3836 series standard. The explosion-proof mark is Exdib mb IIBT4Gb or Ex d e mb II BT4Gb. It has passed the inspection by the national authorized quality supervision and inspection department and obtained the product explosion-proof certificate. It is mainly suitable for places in Zones 1 and 2 where there are explosive gas mixtures in the air, such as petroleum, chemical, metallurgy, pharmaceutical and defense industries
Explosion-proof electrical box
Explosion-proof mark: Ex d ib II BT4 Gb
The electrical box is divided into explosion-proof type and positive pressure type. The outer wall is welded by steel plate, which has high strength, sturdiness and durability, and is equipped with NWN introduction device. Explosion-proof type: It is fully considered that when the explosive mixture invades its interior and explodes for some reason, it will not cause the explosive mixture outside the electric box to explode.
Positive pressure type: The positive pressure type ventilation and explosion-proof electrical control cabinet adopts dielectric isolation ignition source explosion-proof measures to achieve the purpose of explosion-proof.
Explosion-proof compressor Fan
It is produced in accordance with the requirements of the national standard GB3836 series, and the explosion-proof mark is Exd II CT4Gb. It has passed the inspection by the national authorized quality supervision and inspection department and obtained the product explosion-proof certificate.
