With over 30 years of expertise in hydraulic systems, Guorui Hydraulics specializes in providing hydraulic components and system solutions. The company adheres to its business philosophy: "Winning markets through quality, entering markets with integrity, securing markets via service, and dominating markets by brand." It has obtained China Quality Certification Center (CQC) certification and established a four-stage quality assurance system covering raw material selection, manufacturing monitoring, finished product inspection, and continuous product optimization. Its products hold international certifications including EU CE and classification society approvals.

Recently, Guorui launched an integrated smart fan motor with an automatic speed controller. This product combines a high-performance fan motor, proportional relief valve, and GHC12 controller into a single unit, enabling intelligent closed-loop control of cooling systems.

The core technology features automatic speed regulation: The system monitors fan speed in real-time and feeds data to the GHC12 controller. Based on the variance between setpoints and actual values, the controller outputs PWM signals to dynamically adjust motor flow, achieving smooth fan speed transitions. This enhances cooling efficiency while reducing energy consumption, noise levels, and extending equipment lifespan.

Designed for compact construction machinery with demanding cooling requirements – such as concrete pump trucks and pavers – it provides OEMs with reliable, energy-efficient, and easily integrated thermal management solutions.
