Heating element assemblies mounted in a frame that fits inside the duct or air handling unit to deliver air at a controlled temperature, up to 260 °C. Designed to match the duct and the airflow.
A metal frame holds several tubular elements, plain or finned, arranged so the air flows evenly through them. The frame is sized to fit the duct or air handler exactly, and the power is split into stages to control the outlet temperature.
