PURPOSE AND SCOPE OF APPLICATION Новая усиленная конструкция, без изменения весо-габаритных параметров оболочек, позволила расширить область применения оборудования для подгруппы IIC.

Explosion-proof lighted sign PGS-IT35 is used as informational signs, for issuing light alarm signals indoors and on open production sites in hazardous areas, in presence of explosive and combustible gases in order to regulate a person‘s behavior under normal conditions and in emergency situations, it is applied in fire alarm systems and automatic fire suppression systems.

Enclosure of lighted sign PGS-IT35 is made of modified corrosion-resistant aluminum-silicon alloy resistant to salt spray and other chemical substances. Anti-static polymer-epoxy powder coating. Color RAL 7035. Window of explosion-proof lighted sign is made of impact-resistant tempered glass. LED light source for text backlighting.

Thickness of ready product is just 85 mm which enables its usage in containers, container units, in rooms with narrow corridors and passsages, and above main and emergency exits etc.

Chemical substances used for production of explosion-proof lighted signs PGS-IT35 such as glue, compound, conformal coating, greases and seals do not have a negative impact on performance and service life and they do not deteriorate luminous flux level. Suitability of these materials for production of LED circuit board was confirmed by longtime bench testing carried out in own laboratory of "ZAVOD GORELTEX" Co. Ltd.

Design of enclosure of LED signs has a hermetically sealed air filled light indication unit with installed LED circuit boards. This airtight circuit is not disrupted during installation and operation of sign on customer‘s site and prevents ingress of dust, moisture, aggressive atmosphere and gases (e.g. hydrogen supfide) and prevents condensation in case of change of temperature and moisture.

Design features of explosion-proof LED sign PGS-IT35 and materials used for its production enable continuous protection of light-emitting diodes against exposure to aggressive harmful substances on customer‘s site during long-term service life.

3D models of devices are provided upon request.

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.
