Belt-Driven Fan Drive

Posted on March 14, 2013

Horton has developed a new integrated belt-driven fan drive designed for use with larger fans used in trucks and other larger engine applications. The Modulator RCV250 fully variable fan drive is engineered to be light and compact, yet still provide enough torque to drive larger diameter fans, the company said.

The Modulator RCV250 system’s variable operation reduces fan noise, increases fuel efficiency and available horsepower. Its proprietary design and lower parts count results in reduced initial, replacement and maintenance costs when compared to a viscous fan drive and drive hub combination, the company said. In addition, at the end of its life cycle, Horton said it can be returned to the company for remanufacturing.

The new fan drive is directly controlled and managed by the engine’s electronic control unit (ECU) and can also combined with Horton’s Di Controller for more precision cooling requirements. It incorporates  an integral fan speed sensor for close-loop control and a magnetic design that speeds reaction time, which in turn increases modulation and cooling, Horton said.

The bearing and product life of the Modulator is increased due to reduced bearing load. Stationary magnet coils eliminate the need for a bearing which Horton said reduces manufacturing and materials costs.  It is compatible with Horton’s fan technology, including WindMaster Revolution high-efficiency, hybrid-flow fans.

The Modulator RCV250 will be displayed at the Horton booth (34165) at the upcoming Mid-America Trucking Show. It is scheduled to be in full production and available this summer.
