Power Efficiency Control -

Energy savings up to 30% without power loss

Oil diffusion pumps require a certain minimum oil temperature for operation. Commonly, 100% of the installed heating power is constantly utilized. The innovative Leybold power efficiency control unit for diffusion pumps cuts power consumption by up to 30% since the supplied power is significantly reduced after the pump has attained its operating temperature. Further savings result from the utilization of the standby mode at a reduced temperature.

■ Cost reductions through energy-savings (up to 30%)
■ Increased service life of oil and heating cartridges
■ Excellent operating convenience and simple use
■ Fast ROI (< 2 years)
■ Simple, visual monitoring of the parameters
■ PLC driven
■ USB Interface and Ethernet
