The SCALA2, by Grundfos Singapore, maintains water pressure in all taps, even with multiple taps and showers running at the same time. The pump, motor, tank, sensor, drive and non-return valve have been built into one unit. The SCALA2 automatically adjusts performance to both inlet pressure and water consumption in the home. Thanks to a water-cooled motor permanent magnet, SCALA2 claims that their water pressure unit is one of the lowest noise levels of any booster. SCALA2 features a built-in sensor, which constantly measures the discharge pressure. If the pressure drops below the desired level, SCALA2 boosts its operation immediately to compensate for the loss of pressure.
