High performance Finned Tubular Duct Electrical Heater UL
We are the premier fabricator of tubular heating elements for
various applications in the appliance and comfort conditioning
industries. Our products have been custom designed and sold to
original equipment manufacturers, wholesalers, and distributors.
Our reputation as a supplier of electro mechanical assemblies and
sub-assemblies to major consumer
products manufacturers since 1938 has been constantly upgraded
through our ISO 9001, 14001, and 18001 Registrations and our state
of the art research and development facility.
Increasingly sophisticated technology and personnel have allowed us
to hold over 30 key U.S. and foreign patents for the industry and
be certified to participate in the UL client test data program
Each heater is dielectrically tested at 1,000 volts plus twice the
rated voltage times 120%. The resistance of all heaters is measured
and must be within ± 5% of the rated value. A functional electrical
test is performed on every heater by applying control voltage and
energizing all control circuits.
1. Heater is UL listed for Outdoor Applications
2. 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.
3. In a horizontal airflow application, the airflow direction is
not specific; it can go either direction without any modification.
4. 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.
5. All TUTCO duct heaters carry a zero clearance rating for
installations into ducts.
