Forced Circulation – Oil
HOTSTART's Forced Circulation Heaters feature integrated pumps to continuously circulate heated oil — ensuring optimal oil viscosity is maintained throughout the entire oil sump or compressor frame. Heated fluid is kept at a more consistent temperature when it is continuously circulated, resulting in reduced maintenance and improved energy efficiency. HOTSTART Forced Circulation Heaters are available in weathertight or hazardous location models for a wide range of installation environments.
