Panoramica
The Fan Motor Space Heater Interface provides a reliable, integrated solution for coordinating fan motor space heaters with fan motor control systems, including Variable Frequency Drives (VFDs). Designed to protect motors from condensation-related damage, the interface automatically energizes space heaters only when the fan motor is off and ensures they remain de‑energized whenever the motor or VFD is operating. Compatible with any control system capable of providing a normally closed relay contact when the fan motor is not running, the interface offers flexible integration across a wide range of installations. The Remote version is supplied in a dedicated enclosure for stand‑alone mounting, while the Integral version is factory incorporated into the cooling tower control panel assembly.
