Marley Engineered Products, a manufacturer of high-performance heating and ventilation solutions, has released its latest generation of Explosion-Proof Unit Heaters, designed under the esteemed QMark and Berko brands.
Featuring rugged construction and high-quality cold rolled steel powder-coated cabinets to ensure long-lasting performance, the heaters are built to endure the harshest of environments, including areas with a potential for explosion or fire due to the presence of flammable gases, vapours, pulverised dust or ignitable fibres in the atmosphere.
The GUX Series from QMark and the RUX Series from Berko are built to meet stringent 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, making them ideal for a wide range of industrial applications such as chemical plants, oil refineries and rigs, grain elevators, and more.
With an understanding of the damaging effects of corrosive environments, these heaters are equipped with advanced corrosion-resistant coatings and materials, ensuring durability and longevity in harsh conditions.
Optional 316 stainless steel and Heresite coating offer additional protection in corrosive settings.
The Explosion-Proof Unit Heaters are designed to operate reliably and efficiently across a range of temperatures.
The T3C temperature rating of 320°F provides additional reliability and safety, ensuring optimal performance in applications from freezing cold to scorching heat.
Equipped with automatic and manual reset overtemperature cutouts, as well as a low 70 PSIG relief valve setting, the heaters 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, making them suitable for various installation scenarios.
The IP55 motor and type 4 outdoor-rated enclosure further ensure reliability in wet locations. With airflow capabilities ranging from 550 to 3850 CFM, these heaters efficiently distribute warm air across large areas, providing consistent and comfortable heating.
Marley Engineered Products manager, Andrew Martin, said the design team used their decades of experience to meet the highest safety standards and deliver exceptional performance and durability in the most challenging environments.
“The design team engineered these heaters to offer versatile solutions, tailored to projects’ specific requirements in those hard-to-reach areas,” he said.
The new Explosion-Proof Unit Heaters are perfect for use in aircraft hangars and service areas, chemical storage and handling areas, coal preparation plants, compressor stations, paint storage areas and spray booths, and sewage pump stations and treatment plants.
"We understand the critical importance of safety and reliability in hazardous locations, and our new heaters are built to exceed expectations," Martin said.
