PURPOSE AND SCOPE OF APPLICATION
ZKG-N series explosion-proof anti-vandal heated cabinets for I&C are used for protection of I&C against negative impact of low temperature, dust, chemicals, mechanical damage and unauthorized access. The cabinets are located on open sites and in unheated rooms for installation of various Ex equipment, and also as enclosures of local control stations and cabinets if their installation in hazardous areas is required.
The stainless steel robust enclosure protects I&C against mechanical damage, while high level of protection IP66 protects the equipment against dust and moisture.
Various types of heating systems can be installed in the cabinet (electric heating, water and steam heating) that ensure appropriate conditions for the operation of I&C. An additional layer of flexible heat insulating material maintains heat for a long time.
The structure features the removable panels that were specially designed for the convenience of cable glands mounting. Drilling of holes and cable glands mounting can be performed on the work table.
I&C cabinets are available in 2 dimension types, non-standard dimensions of the enclosures and mounting plates are possible upon customer’s request.
Scope of application - hazardous indoor and outdoor areas in accordance with the assigned explosion protection marking - category II for gas subgroups IIA, IIB, IIC, zones 1, 2, category III for dust IIIA, IIIB, IIIC, zones 21, 22.
