Cool Logic Fan Drives

Cool Logic heavy-duty, variable speed fan drives are a breakthrough in engine cooling technology. Not only are they electronically controlled and maintenance-free, they provide improved fuel economy while meeting the needs of the stringent North American heavy duty truck emissions requirements.

Cool Logic drives feature electronic modulating speed control. This means precise temperature control all the time, extending the life of the entire cooling system including the radiator and charge air cooler. Couple that feature with the fuel saving fan speed control scheme and the maintenance-free design, and you’re well on your way to cool savings.​
