Explosion-proof stainless steel boxes of SHORV-N type (CCFE/SS) (flameproof enclosures)


SHORV-N explosion-proof stainless steel boxes are stationary devices that are intended for operation in hazardous areas and arrangement of electrotechnical components, such as terminals, control, signaling elements, etc. at the enterprises of food, chemical, oil and gas and other infustries.

The type of explosion protection - flameproof joint. At the design stage, the enclosures undergo mathematical modelling and tests in order to ensure the conformity to declared explosion protection markings.

Solid cast explosion-proof enclosures of SHORV-N series are approved by the Russian Maritime Register of Shipping and are suitable for application on ships and at the facilities supervised by the maritime register. The enclosures have the certificate of the Customs Union and IEC Ex international certificate.

- Seamless solid cast enclosure made from stainless steel is a unique product in the domestic and foreign markets. It is manufactured uniquely by explosion-proof equipment plant "ZAVOD GORELTEX" Co. Ltd.
- Shape of boxes ensures easy access for installation of equipment inside the enclosure.
- SHORV-N boxes have external flange - tight connection is reached with the adjusting part.
- The box cover is fastened by bolts with hexagonal head and has sealing gasket along the perimeter.
- Areas for grounding connection are provided - outer wall, inner wall and inner side of the box cover.
- The box base has 4 mounting ears for wall mounting.
The design is highly strong and resistant to high temperatures, corrosion and aggressive operating environment, including alkali, salt spray and drops of hydrochloric acid and sulfuric acid.

- Seamless enclosure and technology of molding allows producing an enclosure of increased non-deforming geometrical accuracy and achieve parameters required for explosion protection class IIC (except acetylene atmospheres).

- Service life of the enclosure - 30 years.
Full production cycle from design engineering, foundry patterns to finished products is carried out by explosion-proof equipment plant "ZAVOD GORELTEX" Co. Ltd. in the territory of the Russian Federation.

Новая усиленная конструкция, без изменения веса и габаритных параметров оболочек, позволила расширить область применения оборудования для подгруппы IIC."Х" sign specified after Ex marking indicates that is is prohibited to use the device in explosive mixtures of acetylene and air.

Scope of application - outdoor and indoor hazardous areas, as per explosion protection marking - category II for gas subgroup IIA, IIB, IIB+H2; category 1, 2; category III for dust IIIA, IIIB, IIIC, zones 21, 22; category I for firedamp and dust РВ, РП, zones 1, 2; mines and pits non-hazardous with gas (methane) and coal dust; areas non-hazardous with dust and gas.
