Marley Engineered Products Introduces Latest Generation of Explosion-Proof Unit Heaters

BENNETTSVILLE, S.C. — Marley Engineered Products, a manufacturer of heating and ventilation solutions, announced the release of its latest generation of explosion-proof unit heaters, designed under the QMark and Berko brands.

The unit heaters feature rugged construction and cold rolled steel powder-coated cabinets and are built to endure harsh environments, including areas with a potential for explosion or fire due to the presence of flammable gasses, vapors, pulverized dust or ignitable fibers in the atmosphere commonly found in food and beverage processing facilities, Marley Engineered Products said. 

The GUX Series from QMark and the RUX Series from Berko have been designed to meet the safety standards for hazardous locations, including Class I, Divisions 1 and 2, Groups C & D, and Class II, Divisions 1 and 2, Groups E, F & G. These units are also compliant with Class I, Zones 1 and 2, Group II. Optional 316 stainless steel and Heresite coating can offer additional protection in corrosive settings common in food processing areas, according to the manufacturer. 

The explosion-proof unit heaters are designed to operate reliably and efficiently across a range of temperatures, said Marley Engineered Products. The T3C temperature rating of 320 degrees Fahrenheit can provide additional reliability and safety. Built with automatic and manual reset overtemperature cutouts, as well as a low 70 PSIG relief valve setting, the manufacturer reported that the heaters also provide an added layer of safety by preventing overheating and controlling pressure release.

The explosion-proof unit heaters feature industrial-grade, corrosion-resistant cabinets and louvers. The IP55 motor and type 4 outdoor-rated enclosure further aid in reliability in wet locations. These heaters also have airflow capabilities ranging from 550 to 3850 CFM. 

"We are thrilled to introduce these advanced explosion-proof unit heaters to the market," said Andrew Martin, manager of product management, Marley Engineered Products." Our design team has used their decades of experience and created products that not only meet the highest safety standards but also deliver exceptional performance and durability in the most challenging environments.”

Martin also added: "We understand the critical importance of safety and reliability in hazardous locations, and our new heaters are built to exceed expectations. With these units, our customers can be confident in their ability to maintain a reliably comfortable environment, no matter how harsh the conditions.”
