ZKG-P Polyamide Explosion-Proof Heated Cabinet for I&CPURPOSE AND SCOPE OF APPLICATION

ZKG-P series polyamide explosion-proof heated cabinets for I&C are used for protection of I&C against negative impact of low temperature, precipitation, dirt, dust and other aggressive environmental factors. The cabinets are located on open sites and in unheated rooms for installation of various Ex equipment, as well as enclosures of local control stations and cabinets if their installation in hazardous areas is required.

AGVANTAGES
- Resistant to petroleum products, chemical environment and UV radiation.
- High protection degree against moisture and dust IP66.
- Installation of various types of heating systems - electric heating, water and steam heating.
- Stainless steel hardware.
- 3 types of mount - suspension, on tripod, on pipe.
- Installation of viewing windows upon customer‘s specification.
- Option of installation of lock on the cover.

Area of application: depending in the chosen version and explosion protection marking, the products can be installed in zones 1, 2, 21, 22 and provide explosion protection in explosive mixtures of categories II, III of group IIA, IIB, IIC, IIIA, IIIB, IIIC.
