Round and Custom Duct Heaters

Made-to-order comfort

SDHR-SDHx

As practical as they are efficient, duct heaters supply the energy required to raise a room's temperature to the desired setpoint. Their modulation system and temperature sensor deliver precise and efficient performance, while their modular design makes for easy installation and maintenance. Customize your ventilation system with our standard or custom duct heaters.
