PURPOSE AND SCOPE OF APPLICATION

In accordance with Safety Rules in Russia, the restrictions on application of local control stations with EExe and 2EExed type of protection are in force for Zone 1, application of local control stations with Exd type of protection is required. Explosion-proof local control stations and indicating devices series PKIVA is a reliable control and signaling equipment for hazardous zone 0 (only in intrinsically safe version 0Ex ia IIC или 0Ex ia I), zone 1 (without limitations as per Safety Rules).

Each individual product undergoes thorough acceptance in accordance with accurate quality control plan GOST R ISO 9001-2015 (ISO 9001:2015). Compliance with norms and technical specifications of the customer is verified in accordance with special procedure. inspections are carried out stepwise throughout the entire production cycle. Local control stations are produced according to the latest European and Russian technology, and their price can compete even with outdated samples produced in Russia.

Ready standard modular Exd local control stations  are highly resistant to hydrogen sulphide which is confirmed by TR CU certificates. Service life of flameproof joints of Exd explosion-proof enclosures is more than 25 years. One of the distinctive features of explosion-proof equipment produced by "ZAVOD GORELTEX" Co. Ltd. (former "CORTEM-GORELTEX" Co. Ltd.) is ergonomic design of control, indicating and signaling elements.  Large size of control elements makes it possiple to work in gloves (which is important for outdoor operation at low temperatures). Indicating elements have large diameter (40 mm) and are equipped with reflector, which makes the signal clearly visible at large viewing angle and various degrees of surface dirtiness. A wide range of control, indicating and signaling elements of standard version are offered, a version upon customer’s request can also be produced.

Full production cycle starting from casting molds and to ready product is performed at the explosion-proof equipment plant “ZAVOD GORELTEX” Co. Ltd. (former “CORTEM GORELTEX” Co. Ltd.) on the territory of the Russian Federation.

Scope of application - underground mines and pits hazardous with gas (methane), coal dust; hazardous indoor and outdoor areas in accordance with explosion protection marking, GOST 30852.13-2002 (IEC 60079-14:1996) and areas hazardous with combustible dust ignition, as per GOST IEC 61241-3-2011, dangerous production facilities of I, II, III, IV hazard classes under supervision of Rostekhnadzor and national supervisory bodies of the CU and the CIS countries.
