Modulator® RCV2000

RCV2000 Fully Variable Fan Drives

Precision Cooling for Large-Bore Diesel Applications

Horton designed the first viscous fan drive specifically for high horsepower off-highway applications with 50-Liter engines and larger.

Designed to boost fuel efficiency, reduce noise and extend engine life, the RCV2000 boasts innovations throughout all aspects of the design to improve reaction time and control of modulation to bring the fuel savings, productivity and reliability solutions required by the tough off-highway environment.

Benefits

  • Full-range variable speed control reduces operating noise and lowers fuel costs

  • Lower off-speed decreases parasitic loss to preserve horsepower and provide effective cooling

  • Smooth fan engagements and fan modulation
  • Precise fan control

  • Belt-driven unit is economical to install, reliable and maintenance-free
  • Air-cooled design doesn’t require engine oil or hydraulic oil circulation

Features

  • Innovative reservoir, actuator and valve system delivers a faster response time for maximum cooling efficiency

  • Smooth fan engagements and fan modulation

  • Precise fan control

  • Provides customers fuel savings, noise reduction, and cold weather performance advantages.

  • Integral fan speed sensor for closed-loop control managed by the engine ECU

  • Stationary magnet coil eliminates the need for a bearing, reducing manufacturing and materials cost
  • Front-located fan bearing reduces temperature of pulley bearing, increases grease life and supports fan weight
  • Optimized fins on housing and cover for greater heat dissipation

Applications

  • Mining haul truck and excavators

  • Remote radiator packages

  • Power generation – Diesel generators

  • Construction excavators and wheel-loaders
