G120P variable speed drive – boost efficiency, cut costs

Why a variable speed drive?

Without a variable speed drive, a motor is running at maximum speed and the required flow is regulated by for example a butterfly valve. This means for your customers: high energy costs.

In standard applications, pumps or fans are running in part-load operation (most of the time between 40 to 80%). Due to the physical dependency between flow rate and power needed, significant energy savings are possible.

The G120P variable speed drive possesses important prerequisites for efficiency class A. In fact, the G120P provides a number of strategies for controlling fans and pumps that can achieve up to 60% energy savings compared to conventional control methods.

What customers say

Typical applications for the G120P variable speed drive are fans and pumps in HVAC plants.

Installation and commissioning was incredibly easy. Now, our clients’ systems use a lot less energy. And Siemens is always on call if we need support. What more could we ask for?

Applications – pumps and fans

Smart ventilation-specific functions for all types of events Investment security through

intelligent monitoring, e.g. power consumption Detection of a variety of events –

from belt failure to worn bearing

Smart features tailored to pump installations Integrated real-time clock with

three programmable timers Detection of a variety of events –

from blocked pumps to running dry

Pump application – managing the flow Fan application – bringing in fresh air


System uses the in-built functions of G120P like PID control or hibernation mode to provide up to three zones for CO monitoring and ventilation control No external controls are needed

besides the control switches, sensors and an audio-visual alarm
