Pools and Commercial Aquatic facilities depend on motors to perform a variety of applications, critical to their day to day operations. From Public Leisure facilities, to Schools, to Council Pools, a large number of motors provide the backbone to their facilities, and can typically contribute between 50 – 80% of their total energy costs.
A MASSIVE OPPORTUNITY TO SAVE ENERGY
Pool Filtration motors are designed to operate at only one speed, which is 100% output, regardless of fluctuations in demand. However, the flow requirements for every commercial pool are highly variable, and often, aquatic pumps and motors are ‘oversized’ to perform their given application. Variable Speed/Frequency application can save considerable energy. In each application, FW provides custom VFD solutions specifically attuned to each motor, maximizing energy saving potential.
Incorporating FW’s Variable Frequency Drive system matches the motor’s specific load and frequency to the flow rate required for adequate filtration. FW’s specialised solution not only allows the pump to operate at its maximum efficiency, but in turn, reduces the costly power wastage associated with running at a constant maximal speed. This enables clients to take advantage of reduced demand periods (including non-operational hours), allowing variable flows to be implemented for significant energy savings. This combination often translates in energy savings of between 30 – 65%.
A VFD ALONE IS NOT A COMPLETE SOLUTION
Suppliers of Variable Frequency Drives who install in Aquatic facilities often do so without adequate knowledge in commercial pool filtration. This can create a range of serious issues within the filtration system and ancillary equipment. It is critical the application of Variable Frequency operation in the filtration system is in harmony with performance and energy savings.
Together with the support services of a commercial pool filtration specialist – Aquatics Projects Pty Ltd, and water engineering company – Roejen Services , FW’s technical team has the ability to optimize each motor’s energy saving potential by matching the motor’s specific load and frequency to the flow rate required for adequate filtration – ensuring performance and commissioning of the pool filtration system is maintained.
Typical Applications in Aquatics:
- Filtration Pumps (1ph – 3ph) (30-70% Savings)
- Heat Pumps (20-50% Savings)
- Spa Pumps (20-50% Savings)
- Water Features (30-60% Savings)
- Air Handling Units (AHU’s) (30-70% Savings)
