Explosion-proof local control stations as per customer's specification

"ZAVOD GORELTEX" Co. Ltd. makes use of its extensive experience in the technology of manufacturing of local control stations, indicating and signaling devices as per customer‘s diagram and has been the reliable supplier of explosion-proof systems around the world for decades. The leading Russian companies trust us: Gazprom, Gazprom Neft, Rosneft, LUKOIL, Surgutneftegas, leading international companies Total, BP, Shell, Eni and many other. The manufactured equipment fully meets the requirements of Gazprom and Rosneft. The experience of operation in Russia and former USSR republics from the mid-1970s. The equipment of "ZAVOD GORELTEX" Co. Ltd. is operated from Sakhalin to Kaliningrad and from Murmansk to the Black Sea, in Arctic conditions and in deserts of Turkmenistan.

GoreltEx computer-aided design system is developed for automatic creation of drawings of explosion-proof local control stations and terminal boxes. The program does not require special skills in designing of explosion-proof equipment or deep knowledge of current standards. The system contains special algorithms, which prevent occurrence of mistakes in the process of drawing creation....>>

This section contains the description of explosion-proof local control stations, indicating and signaling devices, rotary switches manufactured in accordance with the customer‘s requirements. These local control stations are intended for sending indication and alarm signals at site and remotely (for example, at the field command station). This equipment is manufactured in Ex d and Ex d e versions.

Explosion-proof local control stations, indicating and signaling devices of "ZAVOD GORELTEX" Co. Ltd. are used in chemical, pharmaceutical and other branches of industry, where explosion-proof equipment is required.

Each product undergoes careful inspection in strict accordance with quality plan GOST R ISO 9001-2015 (ISO 9001:2015). The conformity to codes and customer‘s specifications is regulated as per special procedure. Control measures are carried out consecutively during the whole production cycle of the product. Local control stations are manufactured according to the state-of-the-art European and Russian technologies. They can compete with old-fashioned samples manufactured in Russia in terms of cost.

Local control stations, indicating and signaling devices with "flameproof joint" type of explosion protection are made from modified corrosion-resistant aluminum-silicon alloy resistant to salt spray and other chemical substances, including hydrogen sulfide and hydrochloric acid fumes, salty and acidic mine waters, frictionally intrinsically safe. Ex d enclosures flameproof joint service life is more than 25 years.

Local control stations, indicating and signaling devices with Ex d type of explosion protection are made from  polyester, armored with long fibers of glassfiber with additives of graphite or from stainless chrome-nickel steel or stainless steel grade 08Х18Н10 as per GOST 5632-2014 (AISI 304), resistant to alkali, drops of hydrochloric acid and sulfuric acid, high temperature and corrosion.

IT IS IMPORTANT TO KNOW

Technical Regulation TR CU 010/2011 "On the safety of machinery and equipment". 

Annex 1. General regulations of safety machines and equipment. Clause 15 :

«…Controls devices of a machine and (or) equipment must be constructed so that their form, sizes and contact surfaces of the user correspond to a capture way (fingers, hand) or pressing (hand finger, palm, foot)…»

For the equipment intended for operation at ambient temperatures below zero or in aggressive environment, control elements of the equipment must have the increased size, since the user operates the equipment in protective gloves. It is prohibited to use the control elements that do not meet this requirement.

The combination of buttons, locks and signal lamps, buttons with LED illumination, double-headed buttons, rheostats, pointer indicators, sound sirens, sockets, auxiliary terminals and power sources helps to develop various local control stations and signaling devices based on the customer‘s needs. One of the advantages of local control stations is bright colors of buttons and lamps of the control and indicating modules.

Completing of local control stations with explosion-proof cable glands is carried out based on the customer‘s requirements.

Scope of application – underground mines and pits hazardous with gas (methane), coal dust; outdoor and indoor hazardous areas as per explosion protection marking, GOST 30852.13-2002 (IEC 60079-14:1996), areas with presence of combustible dust, as per GOST IEC 61241-3-2011, dangerous production facilities of I, II, III, IV hazard class supervised by Rostechnadzor of the RF and national technical supervision bodies of the Customs Union and CIS countries.

X sign placed after Ex marking indicates that it is prohibited to use the device in hazardous mixtures of acetylene with air.

Nameplates for buttons and signal lamps are manufactured upon customer‘s request.

Viewing windows made from heat- and impact-resistant glass, multilayer impact-resistant glass or impact-resistant polycarbonate for visual control and sending signals on the sign may be installed on the surface of local control stations.

We design and manufacture typical standard and non-typical non-standard local control stations, indicating and signaling devices in explosion-proof and all-weather general industrial versions of various levels of complexity according to customer’s specification or sketch drawings.

Manufacturing is possible using customer‘s components and components produced and purchased by our company. We use the components of such leading manufacturers as Schneider Electric, Siemens, General Electric, etc. All products are completed in accordance with the documentation provided by the customer. Upon the customer‘s request, we can modify the project using both Russian and foreign components. Upon the customer‘s approval, engineers of "ZAVOD GORELTEX" Co. Ltd. can modify the design documentation in order to apply warehouse components and to replace overpriced equipment. Such measures will help to reduce the term of production, cost of the product and operating costs.

UNIQUE DRAWING NUMBER
Each product configuration has its unique drawing number  - article number which defines the version of the product. Design version of each product is defined by the design documentation which is prepared for a particular version based on requirements of technical conditions TU, GOST R, Electrical Installation Code, Unified System for Design Documentation, as well as other regulatory documents.

For the convenience of consumers, "ZAVOD GORELTEX" Co. Ltd. has developed a unique program for accounting of developed customized equipment. A unique identification code  UVG is assigned to the customized equipment. Engineers of "ZAVOD GORELTEX" Co. Ltd. approve all equipment parameters in the project at different order stages. When ordering, it is sufficient to specify only UVG unique identification number.
