PRODUCTS & services Sweps two-stage heat exchanger CoolTherm flying high with two HVR awards Substations in heat network installations can be arranged in a parallel or two-stage set-up. The two-stage system is commonly used to reduce the returned water temperature. Returned water from the radiator circuit heat exchanger is used topreheat the domestic hot water. The proportion of heat used for preheating and post-heating respectively are set in such a way as to make the most efficient use of the return temperature fromthe radiator circuit. If the building concerned has a substantial demand for hot water, this connection arrangement generally results in a lower return temperature than would be the case from a parallel connection.

Offering four faculties that serve nearly 8,000 students and with a worldrenowned reputation it is fully committed to achieving the highest standards. These ambitions can be seen in every aspect of the universitys operation, which includes aspiring to reach stringent environmental and energyefficiency objectives. Grundfos Pumps has been working closely with the university and key estate specialists to achieve some impressive savings. An upgraded installation at one site alone will save 206,978kWh, which is equal to 22,768 per year. Savings of this nature are achievable when assessing the whole life-cycle cost relating to a pump or pumping. As much as 85% of the total life-cycle cost of any pump system is attributable to the energy that is required to run the pumps, so this is the area that should be focused on.

The facility opened in 2005 and is named in honour of the clubs late life president, and former owner, Sir Jack Hayward. It features two high-quality, undersoilheated pitches, an indoor pitch, a fully equipped gymnasium and a hydrotherapy pool. In addition, the medical and physiotherapy facilities mean the club is the first in Britain to establish a fully accredited, onsite professional sports laboratory. West Midlands contractor Lord Combustion Services proposed replacing existing PU equipment with a precommissioned Mikrofill pressurisation package. This included two 700-litre expansion vessels, two service-drain valves, and a Mikrofill 3 PU unit. The precommissioning involved setting the nitrogen/air charge in each of the vessels to match the cold-fillparameter on the Mikrofill unit. This ensures thatthevessels absorb the correct amount of volumetric expansion.

The electronically controlled ModuSat can be connected over the internet to remote servers, enabling Evinox to check the operation of each unit remotely and adjust settings where required. Evinoxs SmartTalk communication system allows it to carry out scheduled maintenance checks remotely over the internet. The system in each apartment including timings and settings can be fully controlled remotely, with remotediagnostic capability and client support. This can avoid unnecessary call-outs as a result of user error. Fault alarms can also be checked by testing the operation of components. Evinox offer after-care service and maintenance plans with one- or two-year contracts, providing flexibility. It also offers combined packages for energy billing and maintenance, all under one roof and with discounts available.
