PURPOSE AND SCOPE OF APPLICATION

Explosion-proof LED light fixtures SGU01 are the 4th generation light fixtures with ultra-bright light-emitting diodes with high efficiency and luminous flux ~155 lm per 1 W.

Explosion-proof LED light fixtures SGU01 are intended for illumination of industrial premises and open production sites and other places, where explosive atmospheres may be present. Low pulsation coefficient helps to use light fixtures not only as ambient lighting, but also as lighting of working areas of control operators and other service personnel.

Enclosures of explosion-proof LED light fixtures SGU01 are made from modified corrosion-resistant aluminum-silicon alloy, resistant to salt spray and other chemical substances. Antistatic polymer epoxy coating is used to paint the enclosure. Color of painting - RAL 7035. Light-transmitting part of the light fixture - heat- and impact-resistant glass, which is characterized by high mechanical strength, wear-resistance and thermal-resistance in case of rapid change of temperature, chemical resistance, high light-transmitting capability.

Original structure of bodies of Goreltex LED light fixtures increase functional capabilities of the product, the radiator ensures high heat output. The light fixture body does not have such disadvantages as chemical and physical aging of polymers. The service life of the light fixture is more than 25 years.

The body of LED light fixtures SGU01 has two entries for installation of explosion-proof cable glands. Terminals for connection of feeding cables are installed inside the inlet box. Additional terminals inside the inlet box ensure transit connection of the light fixture to cabling.

Universal mounting helps to arrange the light fixture in any working position in space: ceiling, wall or support mounting.

Modular lighting devices with various preset configuration can be designed on the base of SGU01 light fixtures:

– single-row 2-5 SGU01 light fixtures;

– double-row 4-10 SGU01 light fixtures.

Manufacturing of modular stationary and portable lighting devices is possible as per configuration preset by the customer.

Explosion-proof LED light fixtures SGU01 are manufactured on the base of sun-white ultra-bright light-emitting diodes of the last generation "Cree LED" (USA).

Chemical substances used for manufacturing of explosion-proof LED light fixtures SGU01, such as glue, compound, conform coating, lubricants and sealants, do not have negative impact on their performance and service life, as well as do not worsen the luminous flux. The applicability of these materials for manufacturing of LED plates has been proved by tests carried out in GORELTEX own testing laboratory.

The structure of explosion-proof LED light fixtures SGU01 has hermetically sealed and air filled chamber with installed LED plates. This chamber is not destroyed during mounting and operation of the light fixture at the customer‘s site and prevents ingress of dust, moisture, aggressive atmospheres and gases (e.g. hydrogen sulfide), and prevents condensation in case of temperature and humidity change.

Structural features of LED light fixtures SGU01 and materials used for their manufacturing enable to continuously protect LEDs from impact of aggressive substances at customer‘s sites and during the whole period of operation.

Full production cycle from foundry patterns to finished products is carried out by explosion-proof equipment plant “ZAVOD GORELTEX” Co. Ltd. (former “CORTEM-GORELTEX” Co. Ltd) in the territory of the Russian Federation.
