Recently, Ruiyin Hydraulics launched its intelligent fan motor integrated with an automatic speed control unit. This product combines a high-performance fan motor, a proportional relief valve, and the GHC12 controller into a single unit, achieving intelligent closed-loop control of the cooling system.

Its core technology is the automatic speed adjustment function: the system continuously monitors the operating temperature and feeds this data back to the GHC12 controller. Based on the difference between the set value and the actual reading, the controller outputs a PWM signal to dynamically regulate the motor flow, enabling smooth variation of the fan speed. This approach enhances cooling efficiency, reduces energy consumption and noise, and extends equipment lifespan.

Designed specifically for construction machinery like concrete pump trucks and pavers, where space is limited and cooling demands are high, this product provides OEMs with a reliable, energy-efficient, and easy-to-integrate thermal management solution.
