Pump technology and PEM

PEM - Intelligent control that reduces CO2 emissions and saves costs.

The innovative Pump Efficiency Module (PEM) is a speed control, monitoring and analysis concept specifically designed for heating and cooling processes.

Depending on the plant variant, the PEM consists of:

• Sensors and pump speed controllers
• Data on the current energy consumption of the pump
• Innovative control and analysis algorithms, e.g. with a control concept based on ΔT, fixed value in %, flow rate in l/min or fixed value in %.

PERIPHERAL PUMP

• Steep characteristic curve for lower flow rates and high pressures
• Energy consumption increases with increasing pressure
• Previous market standard in TCU in the volume business
• Solid, compact design
• Operating flow rate significantly lower than maximum flow rate
• Moderate efficiency

CENTRIFUGAL PUMP

• Flat characteristic curve, for higher flow rates and medium pressures
• Centrifugal principle, rotodynamic
• Energy consumption increases with increasing volume
• Previously found in high efficiency TCU series
• Robust but larger design
• Flow partially possible up to maximum flow rate
• Very good efficiency
