QuantumFlo, in DeBary, Fla., a manufacturer of pump systems for industrial as well as commercial applications, has released an efficiency-ramping software, iQFlo, which monitors and predicts water demand and shuts the pump when no demand is present, eliminating standby losses. The operating system leverages pump regulation from the PLC to deliver greater efficiency and cost-savings in booster pumps, according to the company.
“iQFlo is a software solution, residing on our controller PLC which has algorithms embedded that provide for all pressure control, sequencing and shutdown,” says David Carrier, CEO of QuantumFlo. “iQFlo is exclusive to QuantumFlo products and is part of a ‘turn-key’ pump package solution.”
Carrier adds, “While variable speed control is more energy efficient than constant speed, iQFlo takes the technology further by relying not on PID algorithms built into the variable frequency drive itself, but by centralizing all decision-making on the PLC.”
Taking the control off the drive itself and putting it within the programmable logic controller (PLC), decision-making benefits from operating speeds 100 times faster than the firmware loaded on the variable frequency drive.
Based on the company’ past experience with variable speed versus constant flow systems, the iQFlo technology capitalizes on measuring and accommodating to variable speed water pressure processes, resulting in noticeable cost and energy savings, according to the company. The automated process is designed to optimize pressure to the inconsistent demands of facilities’ contingent pumping situations.
QuantumFlo’s operating system uses a proprietary algorithm that is said to eliminate typical PID problems in variable speed pressure control. It enhances power savings and system energy performance. The iQFlo technology is said to ensure short payback periods on both pump retrofits and new pump packages for decision-makers such as project managers and system architects.
