Electric duct heater
Marc Climatic Controls
Explosion proof fan-forced unit heaters are third party certified and are primarily used in large spaces such as warehouses and compressor station buildings.
To provide heating for multiple rooms, single or multi-stage finned-tubular explosion proof duct heaters are designed for slip-in or flanged connection in a duct system.
For applications requiring a large amount of heat output or for installation outside of the heated space, custom frame-mounted forced air heaters can be designed.
Marc can design and manufacture explosion proof controls for single or multiple stage duct or frame-mounted heaters and include SCR proportional control when required.
