Energy saving solutions from Norwater AS
Norwater AS has over years used the Danfoss APP High Pressure pumps as a vital part of our reverse osmosis units. These pumps are specially designed for RO and consumes by nature 50% less electric power than the average centrifugal pump.
As a further step to cut operational costs and power consumption, Norwater recently finished testing of 2 x 150 ton systems, including the energy recovery system offered by Danfoss – the «I-Save». This can be offered as an optional extra on most Norwater systems and reduces required electric power to feed the system minimum 40% relative to applying an APP pump without I-Save. For the 2 x NWS4-150 systems tested end of May at the workshop, electric power required (with I-Save) was 12,8 kW. The same model previously required 22kW (without I-Save), a saving of 41,8 %.
