Varifan

Varifan is an advanced thermal management system which provides controlled air cooling of enclosures in an infinitely variable manner.

As well as protecting critical equipment against heat overload other benefits include:

Low power consumption, therefore onsiderable savings on electricity expenditure
Varifan can pay for itself very quickly and boost profit thereafter
Very low noise
Fan life is extended
Alarms will alert management of fan failure
Over temperature alarms provide critical warnings
The smart electronics will increase the speed of fans to compensate for a failing fan thus maintaining air flow
N+1 redundancy with Dual Power Supply option
When integrated with CannonGuard the system will provide alarm alerts over the WorldWideWeb using SNMP
Diagnostics via CannonGuard and CannonView provide 1000 lines of operational history for system management
The Varifan may be integrated into the CannonGuard full environmental control and access system - Click Here for further details

Cannon Varifan - Underside

When the heat load is low the fans are controlled to run at idle or low rpm. As temperature rises the fan speed adjusts steplessly to increase the flow of cooling air, maintaining equipment operating temperatures at pre-determined levels.
