Control Resources specializes in providing cost-effective, unique fan controllers and alarms to the electronics cooling and HVAC industries. With over 250 custom fan control projects completed for top Fortune 500 companies, CRI has the know-how to tackle your next project.
In addition to our custom fan control design capabilities, we offer the off-the-shelf SmartFan® line, which includes 14 AC and DC fan speed controllers and fan alarms that satisfy a wide variety of applications.
Custom Parameters for Off-the-Shelf Fan Speed Control
Many parameters of our off-the-shelf SmartFan® models can be easily modified via firmware or component values to meet custom applications. Some of these parameters include:
- Idle speed
- Control slope (sensitivity)
- Control input (temperature, humidity, pressure, other…)
- Alarm trigger points
- Alarm signal output
- Custom I2C or MODBUS communications
