A continuous and reliable water supply is essential for medical departments, which is why an “Invertek Drives Optidrive Eco” frequency inverter with “Optiflow” technology solution is used in a Middle Eastern hospital.

It previously used two water pumps, which also supplied water to an emergency water tank when the main network supply was interrupted or failed due to a power outage.

“Solcon Industries Ltd”, an “Invertek” sales partner in the country, installed two additional water pumps, controlled by four Optidrive Eco variable frequency drives, to manage and control the supply while saving energy.

“By installing two additional pumps controlled by “Optidrive Ecos”, we were able to implement better supply management. The drives’ Optiflow technology ensures flexible pump control. Thus, when demand is low, it reduces the number of pumps required, but ensures a constant flow at all times,” said Avi Even from “Solcon”.

“Individual pumps do not have to operate at full capacity all the time, which reduces energy consumption, water consumption, and wear and tear, which in turn reduces maintenance costs and downtime.”

Using “Optiflow” allows more than one frequency inverter to operate simultaneously to ensure optimal flow. The first “Optidrive Eco” is the master drive, and the other three are slaves. The master controls and dictates the speed and operating time for the slave drives.

The system is intelligently controlled based on demand, using the internal PID function of the “Eco” drives. The system never experiences mechanical overload, resulting in cost savings due to reduced wear and tear or downtime.

The outlet pressure is continuously measured and sent to the master drive. The master drive then intelligently determines the on/off status and speed of all drives based on its internal PID and “Optiflow” functions.

Four 22 kW, three-phase, size four IP55 “Optidrive Eco” frequency inverters are installed to control four 22 kW pumps.

“This system means the hospital can rely on a continuous and reliable water supply to all parts of the building.”

“Optidrive Eco” frequency inverters can control AC induction (IM) motors, AC permanent magnet (PM) motors, brushless DC (BLDC) motors, and synchronous reluctance (SynRM) motors. The drive product range includes 200-600 V single-phase and three-phase input, and from 0.75 kW to 250 kW, 1 HP to 350 HP.

They are produced in three enclosure variants – IP20, IP55 / NEMA 12, and IP66 / NEMA 4X – and seven frame sizes, with IP55 and IP66 models featuring OLED displays.
