WATER ENGINEERING

The Hilton Hotel, situated in Africa's richest square mile - Sandton, selected Grundfos booster pumps.

When the Hilton Hotel in Sandton was looking to upgrade the water pumping system for its buildings, it wanted a solution that was good for its staff, the business as a whole, and the broader environment; a Grundfos pump set ticked all these boxes.

A ccording to Charmaine Spasojevic, chief engineer at the Hilton Hotel, the company’s focus when investing in new plant is not on short-term economy. “Our prime responsibility is to take care of our team members, the environment and the business itself, so we do not necessarily choose the cheapest item from an initial capital perspective,” she says. The solution selected was a Grundfos Hydro MPC-E booster pump set with four 7,5 kW motors and CIM 500 control system. This provides a complete system which is engineered to offer energy efficient operation with a high level of control capability. The pump set meets all the requirements of the Hilton’s 12-floor, 329-room Sandton hotel, while delivering significant savings in electricity costs. “This new energy efficient installation

“From a management and monitoring perspective, the system integrates seamlessly with our building management system (BMS) and allows us to extract all the available information, and allowing us full control over our service,” she says. The hotel can now monitor various aspects of the pump set, including its running hours, energy consumption and discharge pressure, as well as any power supply problems or water shortages. In addition, the system will alert management when services are required. The new equipment is also exceptionally quiet, notes Spasojevic, enhancing the ergonomics of the working environment. “The pump set runs at such low noise levels that there is no

has allowed us to reduce our carbon footprint, helping us to combat climate change and help fulfil our value of social responsibility,” she says. “Over and above the monetary saving on energy costs, the reduction in size and the added intelligence of the pump set, we will also achieve lower maintenance costs by eliminating separate variable speed drives (VSDs) and thereby reducing the quantity of items in our plant portfolio needing maintenance.” Real-time control Spasojevic points out that the data and communication capabilities of the Grundfos CIM 500 control system add substantial value by providing real-time insight into the pump set’s operation.
