Control Resources
Fan Monitoring & Fan Failure Alarms
Should a fan or blower in a ventilation application fail, the results can be disastrous. In computer and telecommunication equipment, failure of an air mover may cause operational failure or even permanent damage. In ventilation applications, contaminants may build to dangerous levels, equipment may fail or livestock may perish.
Over the past 2 decades, Control Resources has become the leading OEM supplier of fan monitoring and fan failure alarm products to the electronics, telecommunications and HVAC industries. Control Resources offers the SmartFan line of off-the-shelf and custom fan monitoring and fan failure alarms to meet your requirements in the most efficient and cost effective manner.
These fan monitoring and fan failure alarm technologies are available on many standard SmartFan OEM control products and can be provided in custom control and alarm designs.
