Variable Speed Fan Controller (FC-3-2)
Geist Variable Speed Fan Controller (FC-3-2)
With Data Centre managers looking to "green" their installation they are typically drawn to cooling. Cooling often constitutes up to 40% of their energy bill, but making changes to cooling systems to reduce energy costs has to be done in such a way that maintains optimal operating conditions for servers. The Variable Speed Fan Controller (FC-3-2), from Geist, sits at the critical cross section of a successful "greening" strategy. The Variable Speed Fan Controller takes real-time temperature measurements and can automatically adjust fan speed to protect your IT equipment, reduce fan noise and conserve energy.
