Explosion-Proof Heaters FE1

FE1 series of explosion-proof electric forced air heaters are ATEX approved to directive 94/9/EC and designed to provide space heating in areas where flammable mixtures of air and gasses, vapours or mists are present. These rugged and corrosion-resistant heaters are a safe, reliable heat source for demanding industrial applications that include:

  • Petroleum refineries, gasoline storage and dispending areas
  • Sewage or wastewater treatment plants
  • Dry-cleaning plants where cleaning fluid vapours may be present
  • Petrochemical plants
  • Hazardous waste storage facilities
  • Aircraft hangars and fuel servicin areas
  • Paint storage facilities
  • Utility and natural gas plants

 

All FE1 heaters utilize the VacuCore liquid-to-air heat exchanger. The induced vacuum within the sealed core provides greater effciency, even distribution of heat across the face of the exchanger and faster warm-up. When necessary, the entire core can be safely and easily replaced with a new or factory reconditioned exchange unit.

The heater core assembly is contained in a sturdy, epoxy-coated, 2 mm thick steel cabinet which also carries the motor and fan assembly. Adjustable louvres allow directional control of the airflow. A narrow gap, two-piece fan guard is provided to shield all moving parts. All fasteners are zinc plated for corrosion protection.

Ruffneck heaters are built to last. All aspects and details of Ruffneck products are subjected to exhaustive technical analysis and testing during design and development, and are manufactured under a registered quality assurance program. As a result, they have consistently proven their safety and reliabilly.

For mounting the explosion proof fan heaters a number of mounting kits are avaliable. Ask our technical support team for detailed information.
