Turning Heat and Power Plants into Tri-Generation

Heat, Power, and Cold: Making Optimal Use of Energy
Combined heat and power plants (CHP) work according to the principle of combined heat and power. As a result, they use the energy used much more efficiently than would be possible with the conventional, separate supply of electricity and heat. However, many CHP operators are wondering what they should do in the summer with the heat generated. The ideal answer here is the additional integration of an adsorption refrigeration system. Because the conversion of excess heat into cold – e.g. for air conditioning – ensures optimal utilization of the system throughout the year – and can thus improve its profitability. Decisive is an intelligent control system. It helps to optimize the overall system by flexibly coordinating the generation of heat, electricity and cooling.

Economically and Energetically Smart

Combined heat and power not only reduces electricity costs significantly, it also relieves the power plants and supports the decentralized energy supply approach.

The connection to the power grid offers additional advantages: peak loads can be covered by mains power, an overproduction of electricity can be fed into the grid – and network redundancy ensures the supply is always secure.




f.u.n.k.e. Components produces around 75 million plastic articles per year on 25 injection moulding machines. The demand for energy, heat and cold is correspondingly high.

The energy-efficient and sustainable solution: FAHRENHEIT integrated a turnkey energy, heating and cooling module into the existing infrastructure. The cold generated by adsorption is now used all year round for production processes – for example for the cooling of tools. The drive heat for this comes from the CHP of the entire system. This compact CHP solution is housed in a container in a space-saving manner.

Lebensmittelkühlung mit BHKW und Kompressionsabwärme: Kuchenmeister GmbH


Sustainable energy management

Energy consumption is an increasingly important cost factor for companies. Added to this is the environmental impact of greenhouse gases. Therefore, Kuchenmeister works continuously to recognize energy savings potentials, to act on them and to reduce costs and CO2-emissions.

Since 2014, FAHRENHEIT has supported Kuchenmeister on its way to climate neutrality with a highly efficient adsorption chiller model eCoo 2.0. This chiller is used to cool the distribution warehouse in order to efficiently reduce the cooling base load. FAHRENHEIT's CO2-neutral and energy saving technology is driven by the waste heat of a CHP and a compression plant. The adsorption chiller feeds the cold into the warehouse via ceiling cooling using fan convectors. This way, a seamless and environmentally friendly cold chain is maintained at the transfer point for Kuchenmeister's delicious and fresh products.

An exemplary concept is applied, setting a standard for excellent climate protection in the food industry.


CHP supplies the fashion house with electricity and uses the waste heat to cool the sales rooms over several floors outside the heating season.


From tailoring to a successful and environmentally conscious fashion company.
Retailers know that customers are becoming increasingly self-confident and picky. However, the right feel-good climate is just as much a part of a successful shopping experience.

FAHRENHEIT adsorption chillers are just the environmentally friendly and cost-neutral solution. In conjunction with the waste heat from the EC Power 15/30 CHP used for power generation, FAHRENHEIT's new eCoo 10 HC 30 provides the customer the comfort of a pleasant temperature during the hot summer months, and increases the time customers spend in the store. This increases the buying mood and gives customers an even more exclusive shopping experience.

Adsorption chillers are environmentally friendly, save electricity, and reduce the CO2 footprint: For comfortable and environmentally-conscious shopping.

oe Oeding Print

Cogeneration plant: oeding print


For oeding, the issue of sustainability is the foundation for future viability. Through the consistent use of tested and available technologies, oeding print created an efficient production and management building that meets all the criteria for a modern production facility and complies with the high demands regarding resource efficiency and operating cost optimization at the same time.

Responsibility towards the environment and fellow human beings is also very important to the printing company. Accordingly, the company wanted to develop an energy concept that limits greenhouse gas emissions and further environmental damage and that uses resources in an environmentally-friendly way.

The result is impressive: An eco-building with movement sensors to optimize the lighting and heating and which produces the energy needed to heat and operate it itself. This solution is based on the three key pillars: Energy efficiency, energy recycling and energy generation. Hidden behind these three simple points are an extensive amount of measures that use the most modern technologies and procedures.

For an effective energy recycling, oeding print uses technologies such as waste heat recovery from production processes, compressed air generation and combined heat and power generation, and they also store the generated waste heat in high and low-temperature tanks. This is then used to heat storage and sluice areas, to cool the IT centre or to heat water.

The renewable energy is generated with a photovoltaic system, a combined heat and power generation with the building’s own cogeneration plant, as well as an adsorption chiller from FAHRENHEIT.

Sustainable energy savings with FAHRENHEIT and Sparkasse Passau.

Sparkasse Passau relies on the ecological handling of environmental and energy resources and therefore uses a combined heat and power plant plus environment-friendly cooling systems from FAHRENHEIT. The CHP provides 50kW of electrical power and 85.0kW of thermal power in a very compact CHP, just 1.7sqm of floor space, and powered by environmentally friendly gas.

In times of low-interest rates, as the responsible project manager explained, investing in energy and cost-saving technology is an even smarter investment.

A simple idea, because the power generation works with simultaneous heat dissipation and heat consumption. Good in winter, but also beneficial in summer. Then the generated heat of the CHP is converted with an adsorption chiller of FAHRENHEIT into cold, the u. a. the room air conditioning over the existing ventilation system is used.

The advantage of the new adsorption chiller is the high electrical efficiency with a cooling capacity of more than 40 kW.

This not only benefits Sparkasse Passau with a significant reduction of its electricity consumption for cooling by almost 60%, but also the climate in the city.

Cooling Schönebeck's municipal data center


The municipal works (Stadtwerke) of Schönebeck won the German Data Center Award 2016 with FAHRENHEIT adsorption technology. The objective was to facilitate the expansion and reconstruction of the data center based on a CHP power source and an adsorption chiller for sustainable server cooling.

The municipal utilities chose two FAHRENHEIT eCoo 2.0 units, which provide ecologically sensible cooling for the data center in combination with the CHP.
