Horton presents the Modulator RCV250 Fully Variable Fan Drive, a more efficient engine cooling solution for global applications. It is an integrated belt-driven fan drive of lighter, compact design, engineered to turn larger fans that require higher torque.
- Variable operation reduces fan noise while increasing fuel efficiency and available horsepower
- Directly controlled and managed by engine’s electronic control unit (ECU)
- Can be combined with Horton’s Di Controller for precision cooling
- Includes an integral fan speed sensor for closed-loop control
- Magnetic design speeds reaction time, which in turn increases modulation and cooling
- Dynamically stable with a scalable design
- Features high built-in thermal capacity
- Reservoir, actuator and valve system allows faster response time and lower off-speed to maximize efficiency
- Bearing and product life is increased due to reduced bearing load
- Stationary magnet coils eliminate need for a bearing which reduces manufacturing and materials costs
- Front-located cover bearing reducestemperature of the bearing, increasing grease life and supporting fan weight
- Lower parts count results in reduced initial, replacement and maintenance costs when compared to a viscous fan drive and drive hub combination
- Eliminates need for anti-rotation strap which simplifies customer assembly and makes an extra component unnecessary
- Offers opportunities for advanced diagnostics capabilities
- Meets increased cooling and airflow requirements of today’s hotter-running engines
- At end of its life cycle, the product can be returned to Horton for remanufacturing
- Compatible with Horton’s various fan technologies
