TUBULAR HEATERS - FINNED TUBULAR HEATERS

Finned Tubular Heaters

Description
Finned construction is ideal for transferring heat to air or other gases. Finned tubular heaters are manufacturted in a very wide range of dimensions and power ratings. They can be shaped into any pattern, depending on the application. Complete air heating batteries, that incorporate finned tubular heaters, are designed and built to meet the requirements of any civil or industrial-process air conditioning installation.

Applications
Air and gas heating applications.
