Horton's Modulator LCV40 fully variable fan drive and WindMaster plastic LS11 fan that were previewed at ConExpo consist of an engine cooling solution that delivers optimized efficiency and cooling in a wide variety of agricultural, construction, and transportation equipment. Compact and lightweight, Modulator LCV40 and WindMaster LS11 provide improved fuel economy. Controlled by the engine’s electronic control unit, the Modulator LCV40 has high torque and a faster response time. The fan drive’s variable-speed operation and lower off-speed result in more usable epower for auxiliary systems. The fan drive is completely sealed with durable construction for long, maintenance-free operating life. Designed for a broad range of operating conditions, WindMaster LS11 blades can be trimmed to the appropriate size for radiator and airflow requirements. The LS11 blades are computer optimized for minimum deflection, reduced fan stress, and increased airflow stability. Constructed with UV-stabilized materials, the Modulator LCV40 and WindMaster will be available to the market this spring.
