ASB Series Dual-Energy Duct Heater

Duct heaters use forced air to send heat through ductwork. Duct heaters can sometimes function as a primary heating source or work with other heating systems as a supplementary heat source.

Stelpro offers two duct heating options: the ASB series dual-energy duct heater and the SDHR series round duct heater. The ASB series features a dual-energy mode while the SDHR series features a round duct heater.

The Stelpro ASB duct heater comes equipped with a temperature sensor for consistent temperature and to detect overheating. Each element contains manual and automatic thermal cut-outs. They also come equipped with an electromechanical coupling interlock device to prevent two heating sources from starting up simultaneously.

The Stelpro dual-energy duct heater offers these heating modes:

• Dual Energy Mode - heating mode automatically changes depending on the outdoor temperature

• Electric Mode - only the duct heater used

More features include:

• Monopiece galvanized steel cabinet
• Pilot light to identify selected modes
• Diagnostic pilot lights
• 16" X 18" and 19" X 19" sizes
• Modulating elements - separately framed for easy replacement
