Our Company

Over 3 decades ago an Electrical Engineer left a secure corporate career to pursue an idea. Building on decades of experience solving acoustical noise control problems, Warren Kundert invented the fan speed controller. Three patents later Control Resources and its SmartFan® technology began earning a reputation for technically innovative and reliable controls.

As customers began requesting modifications to the SmartFan designs the company found its niche designing and manufacturing custom fan speed controllers and alarms. Then motor and pump speed controllers.

Our customer remains the same: Original Equipment Manufacturers. What we do has broadened to include designing and manufacturing a wide mix of custom and off-the-shelf microcontroller-based and analog power electronics.
