ATEX Certified Lighting 70W - 400W

Cooper Crouse-Hinds H.I.D. Hazardous Area Lighting

 

A range of Ex pendant light fittings for HID lamps has been launched, which are robust but compact and lightweight, making them ideal for use in hazardous area gas (Zone 2) and hazardous area dust (Zone 21 and Zone 22) environments.

The NVMV series Ex pendant light fittings from Cooper Crouse-Hinds are explosion protected light fittings in IEC metallic design, which are suitable for use in harsh or hazardous area industrial environments, particularly where there are high levels of moisture or dust, or where there is a risk of mechanical hazards or impact. The hazardous area luminaires are designed and approved in accordance with IEC/EN 60079, which covers the latest requirements for Ex apparatus.

The Cooper Crouse Hinds NVMV series is available in two sizes for hazardous area lighting: a small enclosure version with power outputs ranging from 70W up to 250W and a large enclosure version is also available with power outputs from 250W up to 400W. All Ex pendant light fitting versions can be used for HPS lamps and MH lamps.

The Cooper Crouse Hinds NVMV Ex pendant light fittings can be installed as wall, ceiling or pole-mounted units, at low or medium heights. Due to their high degree of protection (IP66) and the large permissible ambient temperature range (-45 deg C to +55 deg C), the Cooper Crouse Hinds NVMV range can be used in almost any harsh industrial environment.

Chemical and UV resistant materials are used in the design of the light fittings. The relatively low weight of the Ex light fittings also means easier mounting and handling. Replacement is also made easier, resulting in reduced maintenance life costs for hazardous area lighting installations. A variety of optional external globes and reflectors (symmetrical and asymmetrical) are available, which means customers can select the appropriate light distribution for their application. Safety guards are also available.

Features

The Champ family has the required IEC and ATEX certifications to provide solutions for specification requirements around the world Restricted breathing (Ex nR) protection is standard Provides an integrated ballast with thermal cut-off functionality incorporated into the control gear Identical mounting cover for IEC and NEC applications HPS lamps restrike in 10-30 seconds with the instant restrike option (IR) should lamp extinguish due to system voltage drop or momentary loss Available with the Champ Quick-Clip

Applications

In manufacturing plants, refineries, chemical, petrochemical, and other industrial process facilities, waste or sewage treatment facilities, dockside and other heavy industrial applications In areas where combustible dusts or fibers may be present In areas where ignitable concentrations of flammable gases or vapors will be present In installations where moisture, dirt, dust, vibration, corrosion, and rough usage are problematic

Gordon Low, OEM Sales Engineer at Cooper Crouse-Hinds (UK) Ltd commented: "The Cooper Crouse Hinds NVMV Ex pendant light fittings are designed to our usual high quality. This particular hazardous area series incorporates a hinged top hat with single point fixing. The control gear housing hinges on the mounting and termination cover and is held in position by just a single screw. This enables easy access and closure of the lamp for installation and maintenance purposes.“

“A Quick-Click option is also available, which is designed to increase safety, simplify mounting and installation and reduce the time required to maintain the hazardous area luminaire. After connecting the wires, the Quick-Clip holds the weight of the housing, supporting the luminaire whilst the cover screw is tightened,“ explained Low.

As Gordon Low concluded: “Compared to other competing Ex pendant light fittings currently available on the market, the Cooper Crouse Hinds NVMV series utilise high power factor ballasts, with a minimum PF of 0.9. The hazardous area lamps are also much lighter and more compact, making it easier in terms of installation, transportation and maintenance. The hinge hook is also unique to our product, which also further simplifies mounting and replacement for the installer and end user."
