Electric Blower Heaters
Product Overview

Print this page

Dexon Electric Blower Heaters provide positive air pressure ventilation (where tempered air is required) to equipment or storage vaults, pumping stations, or other confined spaces where a safer, dryer, less corrosive environment is desired for equipment and operator safety. They will maintain 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 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.

All 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.

IMPORTANT:

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.


Examples:
MDH3 -1 would be for ordinary location
