Task

The main priorities when selecting the pumping systems for the shopping centre were to guarantee the highest possible levels of comfort and increased energy efficiency. It was for this reason that Grundfos was selected as one of the suppliers, as the equipment Grundfos presented offered the best value for money, explains Bruno Rodrigues of the Electromechanical Installation Department at Pinto & Cruz, part of the group TEJO - J. J. Tomé - Sousa Pedro - Pinto & Cruz, ACE, the organisation responsible for the special water, electricity, air conditioning and security facilities.

"As a result, we have a functional system whose strengths include energy savings due to the use of speed-variable equipment where consumption can be adjusted when needed. We also must not forget Grundfos' extensive experience in this field, the high quality of the equipment and the specialist technical team, who are able to respond to any situation", he adds.

Result

"To date, I can only say that the drinking water supply pumps, ground water supply for the cooling towers and the irrigation system have worked extremely well, without any fault signals or evidence of performance defects during their intended use.Fortunately we have not been forced to test the fire safety system in practice, however we conducted a few trial runs with excellent results. In general, the equipment supplied by Grundfos has proven to be sturdy and of a high quality, as well as extremely reliable.

With regard to the pumping units linked to the air conditioning system, the excellent performance of the Grundfos pumps provides a sense of confidence and peace of mind. Time spent on corrective maintenance of this equipment is downtime, and the periods in which the equipment is functioning properly therefore equals excellent value for money."
