Emerson Upgrades Appleton Mercmaster LED Luminaires

Emerson

November 14, 2017

Emerson has announced major upgrade of its Appleton Mercmaster LED series, the most trusted LED luminaries for harsh industrial and hazardous environments. Building upon legacy features and setting an even higher bar for lighting versatility, the new Mercmaster Generation 3 LED offers four light distribution patterns, seven lumen output levels, expanded color temperature options, and a wide choice of replaceable globes and mounts.

“Today’s announcement is a continuation of our aggressive strategy to make harsh and hazardous LED luminaires more versatile than ever before and to help Electrical and Design Engineers give their clients energy-efficient, low maintenance lighting with uniformity and comfort at the lowest total cost of ownership,” said Ellen Helm, Manager Appleton Lighting, Emerson. “The Mercmaster Generation 3 LED is highly configurable so it will meet the most demanding task and general lighting requirements, making it a single luminaire solution for new and expansion projects, as well as HID retrofits.”

Engineered to provide long lasting, maintenance-free lighting, the enclosed and gasketed luminaires withstand harsh industrial environments without compromising reliability. Delivering a compartmentalized, durable design for minimizing the effects of elevated ambient temperatures, this luminaire’s single-piece driver housing features separate sections for the terminal block and driver to ensure thermal efficiency; making both installation and wiring easier and promising a long luminaire life. Additionally, the Mercmaster Generation 3 LED’s silicone rubber gaskets seal out moisture, dirt and dust, staying flexible and withstanding high temperatures, while the Extra-High Hinge provides additional protection against accidental ballast housing disengagement during installation or maintenance. Its rugged and corrosion-resistant design is rated for Class I, Division 2 and Class II hazardous locations, marine and wet locations, and is also certified for ATEX/IECEx Zone 2 – 21 and 22 to provide a globally-rated, lighting solution for all harsh industrial and hazardous illumination needs.

Suggested applications are oil refineries, petrochemical facilities, chemical plants, power generation plants, and other areas where flammable gasses and vapors may be present. Non-hazardous models of the Appleton Mercmaster Generation 3 LED are also available and can be used in locations where severe weather conditions, excessive moisture, dirt, dust, corrosive atmosphere or where high ambient temperatures are encountered.

UNMATCHED VERSATILITY

Thanks to the versatility of the Mercmaster Generation 3 LED, hard to illuminate areas such as walkways, wide passageways or decks, no longer need to suffer from poor light levels and uneven uniformity.

For example, the luminaire’s secondary optics are engineered to create four unique types of light distribution patterns (Type I, Type III, Type V, or Type V Wide). Specifically designed to meet customer’s needs, these light distribution patterns maximize fixture spacing, while minimizing the number of total fixtures needed and improving uniformity. As a result, overall project cost is dramatically reduced and employee safety, a critical concern in a hazardous location, is improved. Light distribution pattern versatility is especially important in greenfield and brownfield projects demanding luminaire flexibility due to tough to illuminate spaces and the variety of lighting needs.

In addition, the Mercmaster Generation 3 LED offers four replaceable globe options of Clear Polycarbonate, Diffused Polycarbonate, Clear Glass, and Prismatic Glass to provide application versatility. These high-quality globes help to diffuse glare, reduce hot spots, soften illumination, and increase fixture adaptability.

Seven lumen outputs levels, ranging from 3,500 to 17,500 Lumens (HID Equivalences of 70W to 600W) allow for mounting height and illumination level flexibility. By providing a selection of lumen levels, the Mercmaster Generation 3 LED helps engineers achieve precise foot-candle levels to meet target illumination levels. Expanded color temperature options of warm 3000K, neutral 4000K, and cool 5000K CCT assure the preferred color of light for any working environment.

A new, larger variety of mounting hoods offers the convenience to hang luminaries how and where lighting is needed most. With the Mercmaster Generation 3 LED’s six choices of mounting hoods engineers no longer have to compromise on fixture placement. Wall, pendant, ceiling, and stanchion choices are available to make installing lighting around cabling, pipes and process equipment as easy as possible.

SMART RETROFIT FOR HIDs

Retrofitting HIDs with the Mercmaster Generation 3 LED luminaires ensures important maintenance and energy cost-savings, and can utilize competitor mounting adapters. With a service life of over 100,000 hours and a virtual maintenance-free design, coupled with the convenience of instant-on lighting and superior color rendering, the luminaires are a smart retrofit lighting solution. Most importantly, LED solutions deliver energy savings of up to 70% when compared to HID alternatives.
