A NEW COOLING SOLUTION FOR MISSION CRITICAL PROJECTS
ARMSTRONG FLUID TECHNOLOGY has launched Design Envelope EVERCOOL, a new solution for rapid deployment in mission-critical cooling applications.

Design Envelope EVERCOOL is an automation platform for mission-critical cooling systems. The EVERCOOL platform offers pre-engineered, featurerich options that can be configured on-site. The platform meets the stringent requirements of the Uptime Institute for Tier III data centres, while avoiding the traditional requirements of extensive site programming and customisation. The platform integrates with all brands of chillers, pumps, and automation systems and installs directly with chiller plant equipment. If preferred, the solution can work with any data centre information management (DCIM) system or central building automation system (BAS).
EVERCOOL is said to reduce site commissioning time by up to 30% and reduces overall energy consumption, coordinating cooling system operation to reduce energy costs by as much as 40%.
EVERCOOL uses an innovative design with internal redundancy and a hot-standby controller for continuous uptime. This design approach ensures seamless transfer (in less than 200 milliseconds) between controllers in the event of a failure.
Peter Thomsen, Director, Building Systems Solutions with Armstrong comments, “EVERCOOL is a great approach to accelerate project deployment and reduce project costs on any mission-critical project, including Tier 1, 2, 3 or 4 data centres.”

HEALTHY OUTLOOK FOR HOSPITAL SITE
THE FORMER ROYAL INFIRMARY site in Edinburgh’s Lauriston Place is entering a new era as home to the Edinburgh Futures Institute (EFI). Grundfos Pumps, in association with Balfour Beatty Kilpatrick, has taken up the M&E challenge to ensure that this historic location will continue to encourage yet more ground-breaking achievements. Grundfos is delighted to have been selected as the pump supplier and has already supplied a range of pumps, pressurisation units and packaged boosting equipment to phase one of the development.
When it is fully completed in 2022, the £120m project will see Lauriston Place sensitively restored, extended and upgraded. Not only will it be ready to face the next 300 years but, with the help of many forward-thinking partners such as Grundfos Pumps, it will carry the momentum that it has become famous for, to forge new quests.

MAKE THE MOST OF EXCESS WATER PRESSURE
IT HAS LONG BEEN UNDERSTOOD that small-scale hydro-electric power production can provide a convenient, cost-effective source of renewable energy. This is something that has been explored by the water and wastewater treatment sector for some time. But more recently, the opportunity to harness unused pressure in the potable water pipelines of larger buildings is also being seen as a route to energy savings.
A centrifugal pump, fitted with an impeller of the correct geometry, can operate in reverse rotation mode as a turbine. It works on the same principle as a Francis Turbine. The energy is recovered from the pressure differential (head) while the water flow is passed back into the existing system. A Pump as Turbine (PaT) can be used to generate electricity to the grid network or be directed for local supply. Or, it can be used to drive additional rotating equipment directly.
SPP Pumps has found that, in water supply applications, the technique can help to dampen excess pressure, balance pressure in supply lines or tanks at different elevations, control pressure in closed-loop systems and extract excess pressure at the outlet of a water supply line.
Supported by many years of advanced turbine engineering experience, SPP Pumps has developed a range of field-proven, affordable, low maintenance products based on simple, readily-available components and spares. The company can supply, install and commission split case, end suction and multistage pumps for vertical or horizontal mounting. And it says that, compared with other renewable energy options, the return on investment can be relatively short.
