A Dubai building owner is saving money, energy and carbon from the pumps in his air conditioning systems after a Grundfos energy check.
The customer purchased new, state-of-the-art equipment, extended the life of its system and is providing a better environment for its residents with 50-80% energy savings across three buildings.
It all started when residents of Indigo Tower started saying they were hearing a constant loud noise above their ceilings and in turn, the owner was also experiencing unusually high electricity costs in two of its other buildings, Green Tower (commercial) and Falcon Tower (residential), in Dubai’s Deira district.
Faced with this situation, he worked with Grundfos to determine the problems around the existing HVAC (heating, ventilation and air conditioning) pumping systems, and concluded that the buildings were equipped with oversized pumps, inefficient operation and poor balance in their constant primary cooling systems, and resolved.
After Grundfos’ intervention, at Indigo Tower, pumps using 36 kW per hour were running between 7-10 kW/h. Two years later, the pumps use 81% less electricity than before.
