Horton Inc. has introduced VMaster and Stratis Di viscous fan drive and controller systems, which it describes as an economical choice for customers who seek the flexibility of variable speed along with optimal engine cooling, reduced fuel consumption, decreased noise and more available horsepower for auxiliary components.
J1939 compatible, the controller combines with either viscous fan drive to complete the plug-and-play Di systems.
“Electronic viscous fan drives have clear benefits over the alternatives ¾ direct drive and hydraulic systems—and we’re pleased to be able to provide the controller as well as the fan drive,” says Neal Shawaluk, director of sales for off-highway, industrial and specialty markets for Horton Inc. “Direct drive systems run at full speed 100% of the time, unnecessarily consuming fuel, using horsepower and creating fan noise. Hydraulic systems, while variable speed, are expensive to purchase and maintain and can cause safety hazards if they leak hydraulic fluid. Viscous fan drives, on the other hand, are not only economical but also deliver excellent variable-speed performance and maintenance-free operation ¾ all important features in today’s economy.”
Both viscous fan drives and controller are compatible with many Horton and competitive 20- to 44-in.-diameter plastic, metal and composite fans. Both systems offer precision fan control and improved cooling performance.
VMaster Di is endurance-tested and responds rapidly to changing cooling requirements, has greater torque transmission and provides optimum fan idling speed, its maker said. The fan drives are equipped with a double-row bearing for increased durability and longer product life, and feature an improved fluid flow return path for significantly better heat removal and extended product life. These viscous fan drives also feature a rear electrical connection harness shielded from the fan blades. The fan drives are completely sealed and durably constructed with no maintenance.
The Stratis Di viscous fan drive and controller cools hotter running, reduced-emission engines, according to Horton, and feature a reservoir, actuator and valve system that deliver faster response time on the front of the fan drive to increase airflow and improve cooling. In addition, the unit is equipped with a rear-mounted cable harness. An integral fan speed sensor provides closed-loop control capabilities, and an optimized magnetic design speeds up reaction time for better modulation and cooling, the company said. The fan drive’s housing and cover also feature optimized fins for better heat dissipation.
Both products are designed for off-highway equipment, vehicles and buses, including skid steers, truck cranes, cement mixers, refuse trucks, medium-duty trucks, agricultural equipment and generators.
