SOLARFLO – THE SOLAR THERMAL WATER HEATING SOLUTION
OLARflo is Andrews’ complete ready- to-fit solar thermal water heating solution for commercial applications. The package includes high quality evacuated tube or glazed flat plate collectors, single coil or twin coil duplex stainless steel cylinders, pump station, control unit and system expansion vessels. Evacuated tube collectors are ideal for larger commercial water heating applications as they have a high thermal efficiency of 83%. This is due to the vacuum which insulates the collector’s absorber surface from heat loss via convection. Evacuated tubes can also fulfill different specification requirements in terms of optimising efficiency where surface area is limited. They are available in 20 or 30 tube options with gross collector areas of 2.83m2 respectively.
S and 4.25m2
SOLARflo evacuated tubes are of the direct flow type, which allows the collectors to be positioned flat on a roof or vertically on a façade, offering increased installation possibilities in locations which may be unsuitable for flat plate collectors. In addition, the evacuated
tubes may be rotated by +/- 25°, optimising their position relative to due South in order to gain maximum advantage from solar irradiation. The glazed flat plate alumium tray solar collectors have a 4mm thick durable clear solar glass transparent cover and gross collector area of 2.55m2
. This
results in a high transmission efficiency of approximately 91%, a high absorption efficiency of around 95% and low emission loss of 5%. In common with the evacuated tube collectors and stainless steel unvented cylinders in the range, SOLARflo glazed flat plate collectors carry a 10 year guarantee.
Single solar coil cylinders are offered for use with direct-fired water heaters where the stored solar energy is used to pre-heat the cold water inlet into the heater. Twin-coil cylinders are also available where the lower coil is heated by the solar collector array and the top-coil by a commercial boiler. The single and twin-coil cylinder options offer flexibility with respect to the integration of the solar solution for differing heating system designs and configurations.
The controls for
the SOLARflo system are
designed so that the coil for the solar heat transfer fluid and that for the primary heat source operate in complete harmony to optimise the use of the solar energy. The control unit will prevent the primary heat
source from firing up too quickly and thereby preserve the energy saving benefit of the solar heated water.
SOLARflo can be installed with an Andrews primary heating appliance such as the MAXXflo condensing storage water heater, a continuous direct-fired condensing water heater such as the Supa-Flo, or a commercial condensing boiler such as the Paramount two from Potterton Commercial, also part of Baxi Commercial Division.

Data centre solutions firm set to reduce big spenders’ carbon emissions following further investment
ata centre solutions provider, Unite Technologies Ltd, is aiming to help businesses achieve substantial reductions in their energy consumption and carbon emissions following a further investment round from Finance Wales. The £700,000 equity and debt
D
investment, Finance Wales’ third investment in the company since 2001, will enable Unite Technologies to accelerate the further development of its innovative power and environmental monitoring solutions and expand the company’s presence into North America. Unite Technologies’ power and environmental monitoring solutions can help companies reduce the annual energy consumption of their data centres and IT infrastructures by around 25 per cent. Unite’s monitoring solutions enable companies to make informed decisions about reducing overall energy costs. The company’s solutions provide a consolidated view of energy consumption
and can report this over a network in real-time.
“Companies managing large data centres are under increasing pressure to reduce their energy consumption as well as their carbon emissions in line with government legislation,” explained Simon Terry, Chief Executive of Unite Technologies. “Our power and environmental monitoring solutions help companies minimise their energy consumption and achieve real savings. In most cases, we can help reduce annual energy consumption by about 25 per cent and have a significant impact on their bottom line and green credentials.” Terry added: “Finance Wales’ investment will help us to achieve our plans to further develop our integrated energy consumption monitoring system and break into global markets.” James Henderson, Portfolio Development Executive at Finance Wales,
said: “Finance Wales’ third investment round will enable Unite Technologies to continue developing its innovative power and environmental monitoring solutions. “We are pleased to be able to provide the right level of additional investment at the right time to support a company with such a strong track record for innovation and the ability to break into global markets.”
