OPTIMIZE HVAC SYSTEM PERFORMANCE WITH DEMAND-DRIVEN DISTRIBUTION Replacing control valves throughout the building with smaller pumps, will allow you to reduce the size of your building’s primary pumps and save energy by reducing overall horsepower and providing chillers with targeted flow to meet the exact demands of the building.

Pump programming is easy during installation, and fine-tuning can be done later via the building management system (BMS). SEAMLESS INTEGRATION Distributed Pumping easily integrates with your BMS. Many flexible control options are available to ensure seamless integration based on your operation sequence. Grundfos and their team of knowledgeable partners are available to consult and advise during the design process. AUTOMATIC BALANCING During operation, the pump serving each zone, continuously measures the air duct temperature and automatically adjusts the pump speed to achieve the desired set-point — each zone achieves set-point without over pumping, and wasting energy. IMPROVED DELTA T An unbalanced water loop can lead to a low Delta T, causing the chillers to work outside the best efficiency point (BEP) and over pumping the loop. Distributed Pumping improves Delta T, which ultimately reduces energy consumption. See how in the case study on page 6.
