Multi-Wing America (Burton, OH) is a single-source provider for fan and fan clutch systems. The viscous clutches are either electronically-controlled or air-sensing via bi-metal sensor. These fan-drive systems are suitable for off-highway and stationary equipment, including agricultural tractors, skid steers, excavators, construction equipment, pavers, articulated dump trucks and power generators. Available for small- to large-quantity orders, these products help meet stringent emissions requirements, provide fuel savings and significantly reduce noise. The fan clutches have a broad modulation range, low off-speed and flexible mounting options. This line of products reduces cooler clogging and is maintenance-free with a long operating life. Paired with an innovative customized Multi-Wing fan, the electronically controlled fan clutches are available in a wide torque range, respond quickly with precise modulation and are suitable for low-temperature operating conditions. Lightweight and durable, the bi-metal fan clutches have high temperature sensitivity and a fast response time.
