Built Sector: DrainMiser®

DrainMiser® products harvest waste thermal energy from waste water to reduce the energy used for heating water. A few years ago recycling of waste was unusual, but now this is commonplace. The availability of cost effective DrainMiser® units to efficiently recycle waste thermal energy from water, means that this too can become the norm, resulting in reduced energy use and reduced CO2 emissions, globally. Some of the DrainMiser® products are also useful in commercial/industrial sectors.

The DrainMiser product range includes:

Industrial Processes

We work with various organisations to identify areas in their industrial processes where waste thermal energy could be harvested and turned into useful energy. Usually the aim is to reduce carbon emissions and energy use. Sometimes an outside eye can spot opportunities that those within the plant are too close to see. To reduce the pressure on your staff, we can manage the whole project from identifying possible areas for improvement, through supplier selection, to implementation and monitoring. Our dedicated team are focused on delivering the most cost-effective solutions for your business, making your energy work harder for you.

Transport Sector: Thermiser™

Thermiser™ harvests waste heat from engines in buses, HGV's and trains, enabling this energy to be used on or off the vehicle.

The Thermiser™ system can store and reuse the heat to pre-warm diesel engines, thus reducing emissions and idling times. It is also capable of exporting the energy for use in production of space and water heating, thus reducing carbon emissions used for these.

Defra (Department for Environment, Food & Rural Affairs) initiated an open competition (innovative design for Future Climate resilience) under the Small Business Research Initiative umbrella late 2013.
It invited proposals from companies, academia or from consortia of interested parties connected to the infrastructure and built environment sectors. The competition, which applied to England only for the built environment sector and UK wide for the infrastructure sector, was open to those who have already developed their own feasibility studies for such designs and could clearly demonstrate the ability to produce prototype designs for demonstration within the time frame.
For Greengineering the aim of this project was to improve the performance of thermo dynamic solar assisted type heat pump systems. We built a prototype demonstrator to provide test data. The results have attracted a great deal of interest from the industry.

Greengineering Limited has had its technology recognised by successfully achieving a prestigious Greenius Award. This national "Green Genius" competition was launched by the Deputy Prime Minister June 2012 to drive forward the UK's green growth agenda and to accelerate the UK's development of innovative, near-market technologies. It is jointly funded by Department of Energy and Climate Change (DECC), Department for Environment, Food and Rural Affairs (Defra) and Department for Business, Innovation and Skills (BIS). This is being run on behalf of these organisations by the Technology Strategy Board. The technology which Greengineering was able to present relates to the competition sectors for innovative solutions in water and energy sustainability. This award has allowed Greengineering the opportunity to demonstrate its approach to solving problems in the home and work place, by designing and engineering effective solutions.
This project will focus on producing a system, which will reduce fuel used for heating water and spaces. This innovative new system is designed to control the capture of waste thermal energy from various sources, store it in insulated storage tanks and re-deploy it as required. This control system will be able to identify when thermal energy is available and transfer it to a suitable destination. In addition the complete system includes an energy efficient alternative HVAC (Heating Ventilation and Air Conditioning) system to reduce the reliance on expensive to run air conditioning units. The system will also be able to accept thermal inputs from more traditionally available sources, such as solar thermal panels. The system will be able to be retrofitted to existing buildings, and will be ideally suited to new builds as part of an efficient building programme. In addition, at some point in the future it will be relatively simple to adapt the same system for use in emergency camps, building sites or other locations where fixed energy resources are limited. The sources of captured heat could include: heat transferred from outlets and exhausts (cooking appliances, generators, etc.), heat transferred from wastewater sources, air conditioning or refrigeration units, solar photovoltaic panels, solar thermal panels, any industrial waste heat. This system combines innovative new components with existing technology in a novel way. Although some research has already been carried out, further work in this area is needed in order to prove the scientific and commercial merit of this project. Therefore, Phase 1 of this project will focus on assessing the viability of the system including recommending preferred options.
