Finned Channel Strip Heaters

Finned channel strip heaters are highly efficient heating cells that are utilized in many air heating applications like driers, duct heaters, curing ovens, dehumidifiers and shrink tunnels. These heaters are designed to function in forced as well as natural convection air heating applications.

The core of these heaters are channel strip heaters that have 0.375” x 1.5” cross section. In order to make their exposed surface area relatively larger, finned channel strip heaters utilize 2” x 1.375” aluminized steel fins (Stainless Steel is optional) that are designed in such a way that they grip the channel heater housing and dissipate heat efficiently.

Finned channel strip heaters are made with slotted mounting tabs.

Finned channel strip heaters that operate at a potential difference of more than 300V between their line voltage and the ground,

should be isolated from the surface of an application by secondary isolating ceramic bushings. Bucan offers insulators that are adequate for Ø 1/4” screws. To be able to use these ceramic insulators, strip heaters should have 1/2” x 5/8” mounting slots (factory pre-punched upon request).
