MAINTENANCE MATTERS Hennessy, vice president of marketing and product management. "Modulator RCV250 fan drives are for use with larger fans that have more torque and inertia. They are integrated to work smarter and to save fuel." The Modulator RCV250 will be featured at the Mid-America Truck Show in Booth #34165. It will be available in full production this summer. Product features include an integral fan speed sensor for close-loop control and a magnetic design that speeds reaction time, which in turn increases modulation and cooling. The Modulator is dynamically stable with a scalable design and features a high built-in thermal capacity. Its innovative reservoir, actuator and valve system allow faster response time and lower off-speed to maximize efficiency. 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 reduces manufacturing and materials costs. Also, the front-located cover bearing reduces the temperature of the bearing, increasing grease life and supporting fan weight. There is no need for an integrated antirotation strap which simplifies customer assembly and makes an extra component unnecessary. The Modulator offers opportunities for advanced diagnostics capabilities. For information, visit www.hortonww. com/variable or call +1 651.361.6400 or 1.800.621.1320.
