Biogas plants 1 PASCO dosing station 2 CALIX reception pit 3 EUCO® high performance digester 4 COCCUS® pit storage digester 5 AIO All-In-One-Module (CHP module with system control and material distribution) 6 Transformer station 7 SULA gas-tight fermentation residue store A significant rise in global population, combined with the rapid development of industrialisation worldwide, has resulted in a substantial increase in energy consumption, consumption that is largely based on fossil fuel. As a result, large amounts of carbon dioxide now enter the Earth‘s atmosphere resulting in substantial, long term damage to our climate and environment. Biogas is one of the key renewable sources of energy next to solar and wind. After all, biogas can be produced in a particularly environmentally responsible and CO2 neutral way from sustainable raw and energy-rich waste materials that are available at a regional level. Biogas utilises the natural energy present in organic matter.

Biogas plants for dry fermentation Biogas – clean energy with a big future BIOFerm is in the Viessmann Group the biogas specialist for dry fermentation. We make a real contribution to CO2-neutral energy generation with innovative technologies. Discover biowaste as valuable resource – BIOFerm technology enables the production of primary energy from biowaste and compost. It is environmentally friendly, sustainable and CO2-neutral in production. Only the most rudimentary demands are made of the source material. Food and feedstuffs are not used to generate biogas. Benefits at a glance: - Profitable material management, instead of expensive waste disposal - Additional income for composting and farming enterprises - Affordable, home-grown source material, shielded against price fluctuations - Fixed feed-in remuneration according to the EEG [Germany] - Additional income possibilities through forthcoming CO2 emissions trading - High system availability, minimum idle times - Rapid amortisation - Low operator effort - Low costs for maintenance and wear and tear	Biogas plants for wet fermentation Our core business concerns the development and construction of plants for the production and economic use of biogas. We are not only one of the leading suppliers of biogas plants in Germany, but also one of the few comprehensive suppliers in our sector. Next to building systems, we also offer services covering engineering and development, as well as service and system management. Biogas systems will only operate efficiently and economically if their system technology and microbiology are perfectly matched. Consequently, we follow the maxim „Everything from a single source“. To safeguard a high level of plant availability, our customers are supported by a competent team of specialists, covering planning, permits, process technology, biology and system construction. The conversion of biogenous waste matter into biogas has become an important subject internationally. In many countries, the necessary political conditions and terms for subsidies are currently being created as a basis for the development of the biogas market. In future, we will concentrate even more on selected export markets, although Germany will continue to be our most important core market.	Plants for gas treatment Carbotech – market leader in gas treatment and gas feed-in The treatment and scrubbing of biogas is a key function if biogas is to be fed into the gas mains on an industrial scale, i.e. where it is to substitute imported natural gas. Processing biogas into biomethane gives it almost the same physical/chemical properties as conventional natural gas, enabling it to be fed into the existing gas mains. It can be stored in the same way as natural gas, transported over great distances and can be converted into other fuels, as required. Consequently, biomethane is available for all conventional types of use such as, for example, in CHP modules for the combined generation of heat and power; in industrial boilers and those in private homes; as raw material for the chemical industry, as well as fuel for motor vehicles. Biogas is a local and environmentally compatible sustainable fuel that offers flexible application and a high utilisation efficiency through the fact that it can be fed into the mains.

Combined heating and power stations Tailor-made energy concepts for applications requiring a medium output in municipal buildings, and industrial and commercial enterprises. A gas driven combined heat and power unit (CHP) generates heat and power simultaneously. They are sized to suit residential units and commercial operations. On the heating side, the CHP unit operates in parallel to a boiler. For generating heating water and DHW heating, both heat sources are connected to the heating system.

Air-conditioning technology Fresh and pleasant air – particularly on hot heavy summer days – is pure pleasure. For quite some time now, we have become used to advanced technology enabling us to enjoy a pleasant atmosphere in our cars, in hotels, as well as in offices and business premises. This has lead to our desire to experience the same higher level of comfort produced by a fresh atmosphere in our own homes. There are good reasons for that. Not only do we value a pleasantly cool atmosphere inside when it’s hot outside in summer, but there is also the question of health and the ability to perform, for which air conditioning is important. The optimum ambient climate is achieved on average at a room temperature of approx. 21 °C. In addition, a relative humidity around 50 % is also ideal. However, these values fluctuate severely in the course of the day and thereby influence our performance, concentration and our feeling of well-being. It is good to know then, that advanced air conditioning systems provide the necessary balance by enabling ideal control – day and night. Not only the temperature that is, but also the relative humidity. A pleasant side effect that allergy sufferers will appreciate is the multiple filtering of the ambient air through dust and charcoal filters, as well as electrostatic filters. What is also good to know is that this bonus of freshness and well-being is delivered by technology that users will hardly perceive. No draughts and with the lowest possible noise level – yet in a package that falls into the highest energy efficiency category.

Large heat pumps up to 1500 kW With technical expertise, high manufacturing ability and many years of experience, KWT is the heat pump manufacturer of choice for every special application. KWT works together with its clients to develop solutions that are based on more than 30 years' experience, that will meet practical, everyday needs, and that will overcome any and every challenge. All deadlines and costs arranged can be relied on, with no unexpected surprises. All systems are designed and built based on our customers' performance definitions. All heat pumps and geothermal probes verify this performance on the test bed and in practice.

Geothermal probes KWT brine/water heat pumps – designed with expertise and built with quality. Geothermal probes are durable, maintenancefree heat sources. In conjunction with heat pumps, they provide energy for heating, but are also the ideal heat exchanger for natural cooling. In both cases, KWT brine/water heat pumps utilise the constant temperature in the ground. DHW heating DHW temperatures above 60 °C are often needed. However, especially with larger heat pumps, the demand for DHW heating accounts for the lesser proportion of total output. With multi-stage heat pumps or hot gas decoupling, KWT heat pumps can provide the ideal solution to meet this demand. The use of special safety heat exchangers guarantees global potable water requirements are maintained.	Water/water heat pumps High grade components make KWT water/water heat pumps powerful and reliable in borderline areas. Groundwater at 8 to 12 °C is a very rich heat source for a heat pump, as the temperature level is high all year round. However, fluctuating water qualities usually require special heat exchangers (evaporators) if you wish to avoid having intermediate circuits. Stainless steel tubular evaporators KWT heat pumps for groundwater or surface water are equipped with high grade stainless steel tubular heat exchangers. The benefits are obvious – the evaporator has a large volume and generously sized surface area, so the border regions are not vulnerable to icing up. Light floating parts are simply flushed through with the medium, and aggressive chemical fluids have little destructive effect on the high grade stainless steel.	Air/water heat pumps KWT air/water heat pumps for heating and cooling, in conjunction with conventional heat sources, are an economical solution where cooling is required. Air is readily available as a source of heat. However, even when cooling is required, air can easily absorb the extracted heat. KWT air/water heat pumps make particularly efficient use of air temperatures down to about 5 °C, with which they can cover up to 50 % of the annual heat demand. Heating and cooling Air/water solutions from KWT are suitable for heating and cooling. In both cases, the highest level of efficiency is guaranteed thanks to variable speed DC fans. The special design of the air heat exchangers, with gaps twice as wide as in conventional chillers, optimises heat transfer, lowers the pressure drop of the air flow rate, reduces noise and ensures a fast and efficient defrost process.

Special systems KWT special systems are built precisely in accordance with your requirements, they are reliable in operation, and have been used successfully as system components for many years. Waste water and waste heat from industrial processes contain a great deal of energy, which is only seldom used. KWT has the right expertise to exploit this energy. Even for extremely low outside temperatures of minus 40 °C up to plus 35 °C, there is a matching heat pump in the KWT range. DHW heating Waste water from hotels and leisure complexes is usually at a residual temperature of 25 to 35 °C. At the same time, however, such complexes also require a large amount of fresh hot water. KWT, with its ideally suited heat pumps is best placed to make use of this waste heat and so is the perfect partner for such projects. Their heat pumps are highly efficient and supply a water temperature of 60 °C.	Engineering and service KWT guarantees the components and assemblies in its products will work seamlessly together – from individual support in designing the system right through to maintenance. Heat pumps from KWT guarantee efficient and reliable operation. Following installation, KWT engineers or Viessmann service companies commission the system, check its output and reliability, document all the work and tests carried out, and instruct the future operators. As the only heat pump manufacturer in Switzerland with a complete value chain within its own company, KWT guarantees the components and assemblies in its products will work seamlessly together – from individual support in designing the system right through to maintenance. Outside Switzerland, these services are provided by Viessmann.
