SAV Systems, CHP Technical Specifications

  1. 1. Load Tracker CHP SpecificationsEC Power is SAV Systems’ chosen partner for CHP. We were attracted to theiraward-winning LoadTracker CHP because of the flexibility it offers to makeCogeneration work well in a wide range of applications.
  2. 2. LoadTracker CHP Technical SpecificationsLoadTracker background and CHP Technical SpecificationsEC Power started off in 1994. Backed by serious R & D funding fromenergy giant Statoil, a series of high performance Combined Heat andPower Units were developed.These have since benefited from a programme of continuousimprovement. The XRGI 15G CHP unit was launched in 2008, and hasdone well in European markets. As from 2012, the XRGI 20 has beenadded to the product range.
  3. 3. LoadTracker CHP Technical SpecificationsIn early 2009, EC Power formed a joint venture with SAV Systems UnitedKingdom Ltd. This enterprise has enabled the technical strength of ECPower to be combined with the practical expertise and service-ledapproach of SAV. There are over 150 LoadTracker combined heat andpower installations that are up and running in the UK.
  4. 4. LoadTracker CHP Technical SpecificationsLoadTracker CHP Units are powered by a Toyotagas engine of proven reliability. It is designed forlow maintenance and operates for 8,000 hoursbetween services (for the XRGI 15G) or 6,000hours (for the XRGI 20). The generator canmodulate output down to 40% of maximum; thisis very significant to continuing Combined Heatand Power operations during periods of lowelectric demand.
  5. 5. LoadTracker CHP Technical SpecificationsThe CHP heat exchanger circuits are arranged to maintain flow water at constanttemperature (usually 80C), regardless of return temperature. This makes forsteadier operation. Every LoadTracker CHP unit comes with a thermal storagevessel, and the contents of this are kept as close as possible to flow temperature.When site demand falls away, hot water is diverted to build up unused storagevolume.This means that LoadTracker CHP thermal storage is highly effective in dealingwith peaks in site demand.
  6. 6. CHP and carbon footprints Buildings account for nearly half of the UK’s carbon emissions, and domestic housing accounts for around 27% of the UK total. Action to reduce this pollution continues through Building Codes and Regulations. The use of combined heat and power within district heating systems is a good example of this - it can produce large benefits. The Code for Sustainable Homes (CSH) awards 6 possible ratings (or levels of attainment) for dwellings. These are strongly influenced by the expected energy and CO₂ emissions. Determination of Level is also related to the %age improvement in the benchmark Dwelling Emission Rate (DER) which can be achieved by the use of low carbon technologies like Combined Heat and Power.
  7. 7. Domestic Combined Heat and PowerBy incorporating combined heat and power in community heating schemes, a rating ofCSH Level 3 is eminently achievable.This Level has been mandatory in the public sector for 2 years, prior to being applied tohousing in the private sector as from April 2010. As moves towards a Low/Zero Carboneconomy continue in future, consultants will in due course have to consider theimplications of designing to Level 6.
  8. 8. Working with SAP and BREEAM on CHP assessments SAV do not act as SAP or BREEAM assessors as such. However, there have been fruitful exchanges between SAV and accredited SAP and BREEAM assessors on numerous district heating CHP projects. Such discussion helps consultants to get the best possible carbon reductions from LoadTracker. On a series of 16 school projects that SAV contributed to in the previous year, carbon reductions of between 12 – 25% were estimated for Load Tracker Combined Heat and Power systems. The equivalent figure for 29 care home projects was 9% – 24%.
  9. 9. Working with SAP and BREEAM on CHP assessmentsRegardless of project type, SAV’s CHP consultants have built up wide-rangingexpertise to help with the assessment of CO₂ reduction.Regional weather profiles, property type benchmarking and typical loadpatterns are all used to provide CHP system carbon footprint reductionestimates that are grounded, thorough and clearly explained.
