PRODUCTS & SERVICES Aquatech Pressmain offers new pressurisation unit with degassing options The Aquapack AP pressurisation unit with degassing options maintains pressure in heating and chilled water in domestic and commercial systems. The unit can be placed on the floor or wall-mounted, and contain up to 50,000 litres, for temperatures from 3C to 90C and fill pressures 0.8bar to 14.0bar. The unit can operate a chilled and heating system simultaneously. It comes with twin pumps and an optional degasser, protecting the system and saving space.

The academys coal-fired boilers have been replaced by two 48kW Aerotop M commercial heat pumps and two 120kW Thision L ECO wallmounted condensing gas boilers. The sustainable heat pumps will provide the majority of heating, while the gas boilers act as a low-emission backup if the outside temperature falls below a certain level. After connecting the building to the gas mains, West Midlands-based BSN Group worked with ELCO to integrate the new equipment. The hybrid heating system, combined with the restoration of the roof, funded by the Public Sector Decarbonisation Scheme, will save 134 tonnes of carbon per year for the academy. The new Aerotop M reversible heat pumps are available in outputs from 24kW to 48kW. All models are supplied with flow and return manifolds for arrangements of up to four heat pumps, while 16 units can be managed by a cascade controller.

The additions are the DrainMinor S Shower Waste Pump and DrainMinor C Combi Oven Pump, which incorporate Jung U3KSL submersible pumps. A training course on wastewater and sewage pumping will also take place at the Jung Pumpen centre in Germany from the 30 November to 2 December. The event is jointly sponsored by Pump Technology and Jung Pumpen.

The free-cooling system activates when air temperature drops 1C below the chillers return water temperature, reducing the need for mechanical cooling. A partial free-cooling option is available for computer suites and healthcare with a constant residual cooling need, while total free cooling can be used for industrial processes with a cooling need throughout the year. The heat-recovery system enables chillers to produce hot water up to 80C and provide cooling for use in hotels and hospitals.

It is now in the Smithsonian Institution Tel: 020 7880 6245 Email: cibsedirectory@redactive.co.uk The first centrifugal chilling machine was unveiled in a sheet-metal shop in New Jersey, USA, 100 years ago. Created by Willis Haviland Carrier, the chiller was a precursor to the large-scale air conditioning of theatres, offices and hospitals. Carriers chiller assembled a centrifugal refrigeration compressor, with a shell, a condenser and a chiller in one frame. The units were installed in a Philadelphia chocolate factory and, eventually, a Detroit department store in 1924. This technology is now used in more than 200 industries. Air regulation has made food production safer and hospitals more sanitary. It has enabled digital advancements in semiconductor chips, data centres and robotics. Today, Carrier continues to develop its original chillers. The AquaEdge 19DV water-cooled chiller has efficient free-cooling and heat-recovery options, and the AquaEdge 19MV chiller combines multiple operations in a compact machine. Both feature the energy-saving EquiDrive two-stage, back-to-back compressor technology. Visit carrier.com or follow @Carrier on Twitter www.cibsejournal.com August 2022 59
