Toronto Hospital Boosts Water Supply and Saves Energy

Overview

Toronto East General Hospital on Coxwell Avenue needed to replace an outdated and oversized constant speed booster system. The existing booster system consisted of one 20 hp lead and two 40 hp lag pumps. The 20 hp lead pump was constantly running, even when the hospital required little water. In order to control the water flow throughout the entire hospital, the system was using an old technological method of applying a brake to the pumps, resulting in water and energy wastage. On top of that, the pumps were very costly to operate.

TVS Pump Supply recommended and installed an economic solution: a Grundfos BoosterpaQ pumping system MPC-F-3CR32-3 15 HP 575/3/60. The new BoosterpaQ system consists of three CR vertical inline multistage pumps for variable speed operation, with three 15 hp motors. The variable frequency drive (VFD) located in the multi pump controller slows the pumps down so that they only run at a speed suitable to supply the hospital with the amount of water it needs, while maintaining a constant pressure. If no water is needed, the BoosterpaQ will turn off completely and resume again once there is demand.

The BoosterpaQ system was chosen for the following reasons:

1. The multi pump controller (MPC) alternates between the lead and lag pumps. This, in combination with the pumps running at a slower speed, reduces wear and tear and maintenance costs.

2. The pumping system will consume less power since it requires less horse power and has variable speed.

3. The CR multistage pumps are known for their economical and quiet operation, with one of the highest efficiencies in the market.

4. The package includes a corrosion-free stainless steel base frame, panel brackets and manifolds, which make for reliability, durability and cleanliness.

5. The system is a compact unit, requiring approximately a 20-sq.ft. footprint. It comes preassembled for easy installation and is tested prior to delivery.

6. The control panel is extremely user friendly. It enables manual settings and a change of parameters.

7. The system also includes high system pressure protection, low suction protection, and an Ethernet connection for remote desktop monitoring, as well as a variety of communication modules.

Immediately after the BoosterpaQ’s installation in November 2008, the Toronto East General Hospital began to see an energy savings of 75,000 kilowatts per hour and $5,500 per year. The hospital is extremely satisfied. In addition to the energy and cost savings, staff were able to turn off a second 100 hp constant speed booster system that was operating in another wing and supply the entire hospital with water from the Grundfos BoosterpaQ alone.
