Radisson Blu Lisbon makes radical savings with state-of-the- art Grundfos technology
Radisson Blu Lisbon covers an area of 23,000 m2 with 221 rooms
and an annual water consumption of 28,105.00 m3. Their water pump
system was under-performing, wasting energy and costing too much
money. Grundfos was employed to make a calculation of future
savings on a replacement pumping system including a full evaluation
of the entire building and its pump system.
Grundfos suggested replacing the three obsolete pumps with one
state-of-the-art Hydro Booster MPC-E system. This pump ensures that
flow and pressure adapt to demand for reliable water supply to all
221 rooms in the hotel, meaning greater energy efficiency and
The new solution uses just 0,66 kWh to raise 1 metre of water
compared to the old system, which used 3,25 kWh to raise the same
amount of water. That is a massive 80% saving. The guest experience
in the hotel is also optimised thanks to minimal noise emissions
and constant pressure control.
