CONDAIR
The Condair RO-A reverse osmosis water fi lter is designed for use with humidifi cation systems. It removes 95% of dissolved solids from a humidifi er’s supply water to reduce maintenance, improve energy consumption and limit running costs. When operating on regular mains water, a steam humidifi er frequently needs to drain hot water and replace it with fresh to dilute mineral
levels in the boiling chamber. This requires more energy to heat incoming cold water and impacts humidity control, as when the boiling chamber’s temperature drops, so does the steam output. By operating a steam humidifi er on reverse osmosis (RO) water from a Condair RO- A, these drain cycles are reduced by up to 97%. This reduces the energy and water consumption of the humidifi er and enables a close humidity control of up to ±1%RH.

MHG
MHG Gassero has supplied three Superbox gas- fi red condensing boilers to Exeter College to provide space heating and hot water at the college’s Laurence Building. The 2 x 1MW and 1 x 500kW Superbox boilers, along with ancillary equipment, were installed in a packaged plant room that was delivered to site in two halves. The Laurence Building provides hospitality, hair and beauty courses, so heating and hot water demands are variable through the day depending on occupancy and the courses being taught. The Superbox boilers are integrated with the college’s building management system and have a turndown from 2,500kW to 37kW across the three boilers. This ensures excellent load matching and optimum effi ciency. The new packaged plant room is located alongside an existing packaged unit which will be redundant once the changeover of services is complete.

OVENTROP
Located in Sheffi eld, Graves Tennis and Leisure Centre off ers six indoor and 12 outdoor tennis courts and a range of leisure facilities. The centre uses a huge amount of hot water and, as such it was the clients brief that a mixture of renewable energy systems were used to help meet demands and cut carbon emissions. Oventrop was
selected by mechanical contractors NG Bailey to deliver the full design, supply and installation of a ‘Solcos’ Solar Thermal Hot Water system. 20 square metres of Oventrop MQ high effi ciency, commercial fl at plate collector was selected and mounted on pre-fabricated mounting frames. The collectors were connected to the 1000l storage cylinder using a single length of pre-insulation stainless steel pipe. Control was provided by a Regusol ELH 130 pumpset with a built in pre-wired Regtronic controller.

NORTEK
Warm air heaters are subject to Lot 21 of the ErP Directive, and radiant heaters Lot 20. Minimum effi ciency for warm air is now 72%, while for radiant heaters it is 74%. Crucially, these minimum criteria are applicable for both new installations and when replacing existing products. Nortek’s ErP compliant range includes PREEVA EC,
a unit which provides combined heating and ventilation with optional cooling. The units are available with a wide range of heat outputs and cooling capacities, and as non- condensing heaters with thermal effi ciencies above 91% or fully condensing heaters with thermal effi ciencies of 102%. The design combines high thermal effi ciency, quality components and ease of maintenance. The PREEVA EC range incorporates an EC plug fan for a wide range of air duties and external static pressures. The optional mixing box enables air fi ltration.

VIESSMANN
The Viessmann Vitovalor 300-P fuel cell boiler has been reduced in price from £18,000 to £9,990 after Viessmann’s participation in the new European PACE project. It has gained MCS certifi cation, entitling owners to claim approximately £6,000 over 10 years from the Government’s feed-in tariff . The 45% price reduction makes the world’s fi rst mass-produced fuel cell boiler as aff ordable as a heat pump, while producing electricity and domestic heat. To generate both within a single household, the Vitovalor 300-P comprises a fuel cell unit, peak load boiler, and hot water tank in a single visual unit which requires just 0.65 square metres of fl oor space. Energy savings up to 36% are possible compared to separate heat and power generation and CO2 emissions are reduced by over 30% compared to a conventional heating boiler.

WEATHERITE
Weatherite Air Conditioning has designed, manufactured and installed two new chillers at a Marks & Spencer store in Kensington, London. The contract included the replacement of two 15 year-old York Chillers, which had reached the end of their useful life. The two new Weatherite Chillers were designed and pre-assembled at Weatherite’s manufacturing facility, before being dismantled and then re-built in situ
onsite in a small internal plantroom at the store. Synergy Building Services Consultancy was employed to design the system. Synergy then produced a scope of works to tender the replacement of the chillers. Synergy’s project consultant, Peter Simms, said: “We faced a number of hurdles with this job and Weatherite was the only company that developed a technical design solution that met those challenges.”
