Regulated Velocity Electric Blower Heaters
Product Overview

Print this page

Dexon Regulated Velocity Electric Blower Heaters provide continuous, tempered and regulated positive air pressure ventilation where filtration is required. They will maintain both an adjustable preset airflow velocity to compensate for obstructions to intake or discharge air and an adjustable preset discharge temperature. Large units, 6 kw and up, have staged heating elements to minimize power supply and demand billing charges.

Blower Heaters are easy to install, simply mount unit to structure, then run appropriate conduit for power, remote status and optional features used, run power to unit and make any adjustments if required to fan speed. For easy servicing of units the controls, elements and in most cases the blowers are mounted on a single removable panel. This series also has a built in filter track in the air inlet section.

All Electric Regulated Velocity Blower Heaters are CSA certified or approved for Ordinary Location or for Class 1, Div. 2, Group C & D Locations, outdoor freestanding units are certified or approved for Enclosure Type 3R.

CSA Certification or Approval for Ordinary Location is identified by a -1 at the end of the model number. If a -1 is not present the unit will be CSA Certified for Class 1 Div.2 Locations.
