UL Listed Outdoor Duct HeaterMade in the USA

Custom UL listed duct heaters for Outdoor Applications.

Consult factory for pricing and panel size.

  • Heater is UL listed for Outdoor Applications
  • All of the limit controls in all TUTCO duct heaters are
    automatic resets or are manually resettable. There are
    no devices that have to be replaced when tripped.
  • In a horizontal airflow application, the airflow direction is not
    specific; it can go either direction without any modification.
  • With our wire rack element suspension system, the heater
    coil is less susceptible to airflow shading and allows a very
    small pressure drop across the coils.
  • All TUTCO duct heaters carry a zero clearance rating for
    installations into ducts.
