Co-operation between leading pump manufacturer Wilo UK and Burton-upon-Trent based MCS approved installation company Renewable Heat UK has seen an existing anaerobic digestion plant on a livestock farm expanded and extended to maximise the benefits it offers the farm– Broom House Farm at Oakethorpe, north of Derby.

Renewable Heat UK saw a number of opportunities in the project and with the support of Wilo products, set about introducing new elements to the existing system to show huge improvements in the systems’ output. The newly expanded system saw the inclusion of nine energy saving pumps – Wilo Yonos-MAXO and Wilo Stratos models – that are amongst the most energy efficient pumps on the market.

The new improved anaerobic digestion system offers a raft of benefits that are all making a huge difference to the farm. Now all organic matter produced on the farm can go directly into the digester. This includes cow muck, old bedding, old feed, hedge clippings from around the farm and any other organic matter generated. The system draws methane off the top of the system using it to fire an engine generator that generates 250mW of electricity – 10% of which powers all the electricity required by the farm with the other 90% going to the grid – producing enough electricity theoretically, to supply a small village. The engine in the system has no radiator – it directly heats a large header tank to dissipate the heat, and this water is then pumped around the site using the Wilo pumps to share the heat across the site.

The low methane slurry that is the waste product of the anaerobic digestion can then be spread on the fields, benefitting from an 80% reduction in smell as a result of the anaerobic process that has resulted in a major reduction in complaints from the farms neighbours. In addition the fertiliser is activated far more quickly on the fields after digestion, rather than having to lie on the fields for some time waiting to start the assimilation process.

But the benefits don’t stop there. The heat generated by the system’s engine sees the drinking water for the cows heated to 30 degrees C which has resulted in an 8-10% better milk yield and the cow shed is heated to 20 degrees C resulting in faster growing, healthier calves on the farm as well. Healthier animals require far less antibiotics, reducing cost and other fears regarding the long term use of such drugs on animals which contribute to food supplies for human consumption. The cows also benefit from better quality feed as in the past feed was put out and left for the cows to eat. Now fresh food is put out every day and the old feed goes into the digester.

Rob Ridley says the partnership with Wilo has paid off handsomely: “We were delighted by the help Wilo was able to provide and the farm is benefitting hugely from the newly extended anaerobic digestion system. It’s a model for livestock farms across the UK that could be benefitting from a similar holistic approach to raising stock, maximising milk yields, generating high quantities of electricity, much of which goes to the grid providing additional income for the farm. It’s not just a win, win situation it’s a ‘win to the power of four or five situation’ when you step back and take a closer look at all the benefits the system offers the farm.”

“We were delighted to be involved in the project,” says Wilo UK’s Morgan Warren-Ross. “It’s always rewarding to be involved in a project that offers something slightly different, and the success of this one is far reaching and offers serious opportunities for other livestock farms to learn from the installation and to benefit from additional income streams.”

Micronics flowmeters were used at Heathrow’s Terminal 4 to survey the energy usage in the heating system. The facilities staff at Heathrow Airport, Terminal Four have a five year plan running from 2014 to 2019, entitled Quinqennium 6 and this plan included the redesign of the heating system, which currently runs at medium temperature hot water (120oC). They required the system to run at a lower temperature in order to be more cost effective, more environmentally friendly, and crucially, safer. To enable this, they needed to log all data during the winter of 2014 so they called in Balfour Beatty, the Delivery Integrator for all building works for Heathrow Airports Ltd, to carry out an energy flow investigation.

Luke Hirst, Balfour Beatty’s Project Manager heard of Micronics from Nick Wells of Power Plan Limited, a Kent company who specialise in the supply, planning and installation of secondary power systems who had used  Micronics flowmeters at Terminal 5 and was particularly impressed that there was no need to cut into the pipework. This would have been extremely disruptive to the Airport, necessitating the temporary shutting down of the whole Terminal heating system. Micronics recommended the use of the U1000 and U3000 flowmeters, with energy calculators and data loggers. They offer a quick and reliable flow measurement solution. They are configured for pipe size so only nominal configuration on site is required, minimising intervention. The easy to follow menu made it a very cost-effective alternative to a traditional in-line meter. Furthermore, dry servicing is possible so that downtime is kept to a minimum which is especially important for the smooth running of such a busy terminal.

Luke Hirst was enthusiastic about Micronics flowmeters. “Operation has proved exceptional. The surveys were carried out without affecting the terminal. As a result of the survey the design of the replacement heating system is being carried out now. We will definitely use Micronics flowmeters on future occasions when the need arises to carry out another survey.”

REHAU has posted a new animation on its dedicated YouTube channel to show specifiers that, while its Polytec composite curtain walling system might look just like aluminium systems from the outside, its real secret lies underneath.

The animation literally lifts the aluminium exterior off the curtain walling to reveal the steel sections which are at the core of the system and the PVC-U which is on the inside.

It explains the structural benefits which come from using steel, which is up to three times stronger than aluminium sections with the same geometry, and the fact that the PVC-U interior is low maintenance, warm to the touch and available in any RAL colour.

Malcolm Taylor, REHAU’s Product Manager, explained: “REHAU Polytec is a triple strength glazed curtain walling system which is unlike any other on the market. It combines the inherent benefits of three materials to deliver real performance benefits over conventional aluminium systems but retains the slim sightlines and huge range of colour options which specifiers demand.

“For large spans in particular, it offers huge benefits and this quick one minute animation perfectly illustrates that.”

REHAU Polytec is a Passivhaus Trust A Plus certified product and has successfully been tested to the CWCT (Centre for Window and Cladding Technology) standards for severe weather performance.

ETAF Management (Energy, Training and Facilities), are experts in the specialist field of Energy Management. In February 2015 they were confronted with the need to verify for tax claim purposes the ‘useful heat’ used for a 778kW combined heat and power unit in a major hotel group. Alvaro Alvarez, ETAF’s Architecture Technician searched the internet for a solution and discovered the Micronics U3000 which seemed to fit the requirements exactly. The Wiltshire-based company aims to optimise plant operations to achieve proven energy savings of as much as 30% in hotels throughout Europe, working for major groups such as the Carlson Rezidor Group, Jury’s Inn, Marriott and Hyatt as well as smaller groups, and their contribution to the bottom line is highly valued by their clients. The Micronics flow meter allows accurate flow measurement from outside the pipe so there is no need to cut into pipework making measurement quick and simple. The Ultraflo’s easy to follow menu and simple set up makes the calculation of liquid flow effortless and reliable. The whole Micronics range of fixed and portable clamp-on flow meters provide a cost-effective alternative to traditional in-line meter installation for a wide range of applications. In addition, dry servicing means minimum downtime saving both cost and time. Compact, rugged and reliable, the Ultraflo has been designed to provide sustained performance in industrial environments and was ideal for Alvaro’s needs.

“I wanted to try an alternative flow measurement and have been delighted with my choice of the Micronics U3000 which offered exactly what I was looking for. We deal with very big volumes so wanted relatively easy, surface mounted installation. The U3000 offered exactly the features we needed and I would have no hesitation using it in other projects where precise flow measurement is required.”

The potential for similar use is significant and ETAF’s experience is an example of how Fixed Ultrasonic technology can be successfully implemented to gather information on water and energy use.

Leading air conditioning manufacturer LG Electronics is working with Bristol based contractor Sugoi Solutions to fulfil a contract they won from B&Q for an R22 refrigerant replacement programme. It’s a programme that is seeing air conditioning equipment in more than 250 stores across the country replaced with new equipment that meets the ‘F’ Gas regulations.

It’s a significant contract worth in the region of £1.4 million, and one that has had complex logistical ramifications. B&Q will not only end up with fully compliant air conditioning systems in all their ‘back of house’ store areas – the staff areas and administrative offices – but with a full asset list with every detail they need for the future. For each branch Sugoi has provided a list of the replacement units, a signed permission to undertake the work, a risk assessment, a health and safety assessment, an F Gas Logo Sheet, pressure test sheet, evacuation test sheet, a commissioning record sheet and photography of each unit, internal and external before and after, so B&Q has a photographic record of every one of the more than 1000 LG air conditioning systems installed in their stores.

Sugoi director Ben May says it’s been the most comprehensive package of information they have ever provided as part of a replacement equipment contract: “We’ve undertaken the work in B&Q stores across the UK from the north of Scotland down to the Channel Islands! We’ve attended all the sites and organised access to the air conditioning systems, organised for the safe disposal of the R22 refrigerant in each case, sorted the removal and disposal of the existing kit and reinstalled like for like equipment. We’ve audited the work throughout the process and achieved 96% scores on the on-site audits of our work and as a result of the work we’ve done we’ve secured the maintenance contracts on all the equipment we’ve installed. We’ve provided comprehensive documentation for every store and for every piece of equipment we’ve installed.

“This is the biggest single contract we’ve ever undertaken and we’re very proud of the outcome. LG equipment is excellent to work with and the support we’ve had from LG has been first class.”

Andy Reed, Head of Air Conditioning and Energy Solutions at LG says he’s been impressed with the work Sugoi Solutions has undertaken: “We were delighted to win this contract from B&Q but clearly needed an installation partner who was up to the task. We’ve been impressed by the work Sugoi has undertaken in two phases of the project either side of a period when B&Q did not want any contractors on site working in their branches. The information packs they have provided to each and every B&Q branch and their head office have been excellent.

The equipment selected by B&Q for its stores included a selection of split and multi split systems, wall mounted units and ceiling mounted cassette units. The contract was won by LG due to the company’s technical capability, the product energy efficiencies, along with the ability to supply the units to a very tight time schedule and the agreement to an extended warranty on the products.
