ZKG-N Stainless Steel Explosion-Proof Heated Instrument Enclosures

Product Description

ZKG-N heated instrument enclosures are used to protect control and measuring instruments from the negative effects of low temperatures, dust, chemicals, mechanical damage, and unauthorized access. These cabinets are ideal for outdoor installations and unheated spaces, housing various explosion-proof equipment, and also for use as control cabinets and control panels when installed in hazardous areas.

The robust stainless steel enclosure of the thermal cabinet protects control and measuring instruments from mechanical damage, while the high IP66 protection rating helps protect equipment from dust and moisture.

The heating cabinet can be equipped with various heating systems (electric, water, and steam), ensuring comfortable operating conditions for control and measuring instruments. An additional layer of flexible thermal insulation ensures long-term heat retention.


A unique design feature is the inclusion of removable panels, specifically designed for easy installation of cable glands. Drilling holes and installing cable glands can be performed on the workbench.

ZKG-N heated instrument enclosures are manufactured in 2 standard sizes; upon customer request, non-standard sized housings and removable plates can be manufactured.

Advantages

  • Resistant to aggressive environments, alkalis, and drops of sulfuric and hydrochloric acid. Various heating types are available. Inspection windows can be installed according to customer specifications. Removable plates for cable glands are available. Models with classic, diagonal, and split openings are available. A lid lock is optional.
  • Custom made

The Ex marking of an instrument cabinet is determined based on the installed explosion-proof components. The temperature class and maximum surface temperature in the explosion protection marking depend on the temperature class and maximum surface temperature of the installed equipment. Ex marking of I&C cabinet is formed taking into account Ex components installed. The temperature class and maximum surface temperature in explosion protection marking depend on the temperature class and maximum surface temperature of the equipment installed.
