Energy-saving

Zoom in

Fully automatic, non self-priming, frequency-controlled duplex pressure boosting system made from stainless steel (1.4301) for particle-free water. Due to frequency adjustment, the system keeps the selected operating pressure extremely constant even with changing flow requirements. Pressure surges in the system are avoided by the intelligent control system, thus continuous partial load operation is provided in wide flow ranges. The system operates much more energy-efficiently and quietly than unregulated systems. The set pressure can be adjusted with the optionally available programming device (communication adapter for Android and iOS devices). If the water consumption increases, the second pump switches on automatically, so that double the nominal flow rate is available.

Benefits

• Reduction of energy demand and operating costs by up to 30 % compared to unregulated systems
• Lower maintenance costs and longer unit service life by avoiding pressure surges in the system
• Very quiet operation due to frequency control
• Operating voltage and frequency suitable for almost all international networks
• Integrated control of media temperature
• Energy Efficiency Class IE5
• Redundancy of the pumps and sensors enables maximum operational reliability

Applications

• Increases the pressure in the water supply pipe to a constant value, can be installed upstream or downstream of water softening, reverse osmosis or other water treatment installations
