The Solution

Grundfos energy consultants were approached to study the performance of existing HVAC & pressure-boosting systems. With thorough energy audit, it was revealed these operational issues were due to oversized and outdated pumps in the HVAC and pressure-boosting systems. 

To tackle pressure-boosting challenges in the hydropneumatic system, fixed speed pumps were replaced with highly efficient CRE pumps with built-in variable frequency drives (VFD).
