Pressure boosting system, in accordance with DIN 1988/T5 standard.
The speed of all pumps is adjustable.
Starting from 0.37 and up to 22 kW, all stations are equipped with CR, CRE pumps, with motors with an integrated frequency converter and high-efficiency permanent magnets. The overall efficiency of these electric motors is better than that of engines conforming to the IE4 standard according to IEC60034-31, although this standard applies only to electric motors.
From 3 to 22 kW, the stations are equipped with CR, CRE pumps, with built-in frequency converters. The overall efficiency of these electric motors, including those with a frequency converter, is higher than class IE3 according to IEC60034-31, although this standard applies only to electric motors.
