General Information
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 (CTDP).
Quality Control
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.
Why TUTCO
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.
