China manufacturer Industrial Cartridge Heater with Thread UL
General Information
A cartridge heater is a tube-shaped, heavy-duty, industrial joule heating element (electrical resistance) used in the process heating industry, usually custom manufactured to a specific watt density, based on its intended application. Highly compacted they reach a surface watt density of up to 30 w/cm².
It may be used to heat any kind of substance or material, such as oil, air, or sugar. However, a common application is plastic pellets, which are melted in order to form molded plastic parts. An example of such a process is the "hot runner" process. Cartridge heaters resemble tubular heaters structurally but tend to have higher watt densities.

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.
