Benefits of AC motor speed control and cooling solutions
Benefits of using SmartFan AC motor speed controls and air mover controls include acoustical noise reduction, energy savings, environmental (humidity, temperature, pressure, flow) regulation, greater system reliability and improved safety. |
Applications
for our AC Motor Speed Control Solutions |
 |
 |
 |
Pump Control
SmartFan AC controls are capable of controlling small AC pumps based on a control signal (0-10 VDC, 0-20 mA), remote transducer or temperature sensor input. Typical applications include fan coil heating, hot water circulation, solar heating and radiant heating |
Clean Room Pressurization
SmartFan AC controls can be used to help keep positive pressure in clean rooms. By connecting a pressure transducer to a SmartFan control, fans can automatically speed up when a drop in pressure is sensed (door open, clogged filter) and slow down as pressure is returned to normal.
|
Humidity Control
When a humidity sensor is connected to a SmartFan AC control, the relative humidity in indoor pools, spas, locker rooms and bathrooms can be regulated automatically. |
 |
 |
|
Ventilation
SmartFan AC controls can be used in conjuction with a ceiling fan, attic ventilator or duct fan to remove hot air or noxious fumes. Here at Control Resources, we use our own Nimbus fan control to sense heat from our wavesolder and reflow ovens, turn a duct fan on or off automatically and vary fan speed to reduce HVAC costs and increase fan life. |
Electronics Cooling
All of Control Resources' AC & DC Controls can be used in electronics cooling applications to regulate air mover speed to control temperature and reduce acoustical noise. Typical applications include file servers, ATE products, storage subsystems, medical devices and telecommunications equipment. |
