Keep Engine Temperatures Under Control with a Derale PWM Electric Fan Controller

Take complete control of your engine temperature with Derale’s new Pulse Width Modulation (PWM) Electric Fan Controller. The PWM adjusts fan speed to maintain the engine temperature you select. The controller’s Soft Start technology continuously monitors your engine's temperature and runs the fans at the optimum speed. It ramps up the fans slowly, which eliminates harmful amperage spikes and reduces electric motor wear. In fact, Derale says fans often only run between 40-60% of capacity with the PWM.

PWM Controller Features
• Adjustable temperature setting between 160° and 210° F
• Controls fan(s) speed from 0-100%
• Constantly adjusts fan speed to maintain the desired temperature
• Controls multiple electric fans up to 65 amps combined capacity
• Includes automatic reset circuit breaker
• Built-in air conditioning override circuit
• Finned aluminum control box

The Derale PWM Electric Fan Controller unit works with single or dual electric fans and comes with a push-in radiator temperature probe and all necessary wiring and installation hardware. You can use a Derale temperature probe adapter (DER-16737) to locate the probe directly in a 3/8 inch NPT engine block water jacket port. This will give the controller a very accurate temperature reading.

This video will show you how the PWM Electric Fan Controller operates.
