FE2 heaters are CE Marked & ATEX Approved to Directive 94/9/EC for use in hazardous locations. They are designed for dry indoor industrial applications such as oil refineries, petrochemical plants, pulp and paper mills, hazardous waste storage facilities, wastewater treatment plants, etc., where specific explosive gases or dusts maybe present. IP55 rated units available.
All FE2 heaters utilize the VacuCore® liquid-to-air heat exchanger. The induced vacuum within the sealed core provides greater efficiency, even distribution of heat across the face of the exchanger, and a faster warmup. When necessary, the entire core can be safely and easily replaced with a new exchanger or core.
The heater core assembly is contained in a sturdy, epoxy-coated, 12-gauge 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.
All aspects and details of the FE2 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 reliability.
