	SmartFan Applications

	Pump Control The SmartFan Stratus and Nimbus-HP are capable of controlling 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. The SmartFan Nimbus can be used for small AC pumps commonly found in hydronic heating applications.

	Clean Room Pressurization The SmartFan Nimbus, Nimbus-HP or AC-VX can be used to help keep positive pressure in clean rooms. By connecting a pressure transducer to a SmartFan control, fans would automatically speed up when a drop in pressure is sensed (door is opened, clogged filter) and slow down as pressure is returned to normal.

	Electronics Cooling Control Resources offers the VariCool™ fan tray line, 12 families of off-the-shelf fan controls and alarms and 11 off-the-shelf sensors that cover most electronics cooling applications. However as no one can anticipate all customer applications Control Resources offers custom design/build services as well. Since 1984, Control Resources has designed custom controls and alarms for over 200 custom applications. If you don't see exactly what you need in our catalog, let us quote you on a tailor made product.

	Humidity Control When a humidity sensor is connected to the SmartFan Nimbus, the relative humidity in indoor pools, spas, locker rooms and bathrooms can be regulated automatically.

	Medical Equipment & Power Supplies Controlling the speed of cooling fans in medical equipment such as laser and ultrasound systems will reduce acoustical noise for patient comfort and regulate temperature for improved system performance and reliability. The SmartFan Wisp is a temperature sensor, control and temperature alarm circuit contained in a ½"D x 3" probe that can be mounted in the exhaust or inlet of any heat producing equipment. For controlling multiple fans or unusual fan types, the Wisp is a cost effective choice.

	Telecommunications Equipment Control Resources specializes in fan controls for the telecommunications industry. The Fusion, Vortex, Multi SR , Multi SD controls and VariCool™ fan tray were specifically designed for telecom applications. Features of the Multi SR or SD include. Accepting diode OR'd dual power feeds from 10 to 75 VDC Soft start and current limiting Controls 12, 24 or 48 VDC fans Speed control can be based on temperature, a PWM DC signal or via a serial communication (I2C) bus.< Multiple programmable alarm and fan status outputs. Voltage boost circuit that will maintain required voltage to fan even when supply voltage drops below that required. approved and certified ATCA compliance is available The Fusion, Vortex, Multi SR and Multi SD are very versatile. However, should your application not be met by one of these standard products, Control Resources can offer you a complete custom design/build solution which will be sure to address your needs. Since 1984, Control Resources has designed custom controls and alarms for over 200 custom applications. Long time customers include; Lucent, Cisco, NorTel, Ciena, Marconi, Sonus, EMC, Hewlett Packard and Fujitsu . If you don't see exactly what you need in our catalog, let us quote you on a tailor made product.

	Fan Failure Alarms If cost, and safety are your overriding concern, the SmartFan family of tach sensing alarms (TachScan or TachStrip) can fit the bill. These alarms will monitor fan speed or equipment temperature and send an electrical signal that can light a LED, sound an audible alarm, send a logic signal or flip a relay.

	Ventilation SmartFan Nimbus and Nimbus-HP can be used in conjunction 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.
