CHP service around the clock

 

We are the CHP service for your combined heat and power plant – whether in agriculture, industry or local authorities.
We maintain, repair, exchange and retrofit. Aggretech – the top biogas service in southern Germany, France, Switzerland, Croatia, the Czech Republic and the Netherlands.

We have all current MAN biogas engines in stock several times. No matter which packager or plant constructor: we repair all brands.
Our range is so wide that we have almost all peripheral parts at our disposal and can react immediately in case of emergencies. Our emergency service is available 24 hours a week.

We work with MAN original parts and original equipment goods directly from the manufacturer – no imitation parts!

Direct contact with MAN enables us to handle all engine-specific warranties. Likewise, through our direct contacts with our suppliers such as Heinzmann, Enserv, Hügli, Motortech, Kelvion, ESBE, Reich etc., we can obtain all parts in the shortest possible time if we should ever have something not in stock.

Aggretech GmbH & Co.KG offers you top quality CHP service

Regular maintenance of the cogeneration units is essential. Therefore, we also offer maintenance contracts but also full maintenance contracts.
You need a replacement engine? No problem: we will make you an offer.
You can choose between a completely repaired engine or an original new engine.

We offer everything for the MAN product range

Our service extends throughout Germany and into border countries such as France, Switzerland, Holland and the Czech Republic.
We carry out site-independent commissioning for various plant manufacturers.

Questions about the 44th BImSchV? No problem: we have a solution for all medium-sized combustion, gas turbine and internal combustion engine plants to comply with and monitor the guidelines.

Through direct cooperation with 2G, only we can offer you the V36 cylinder heads for the MAN 28xx engine series.
These heads mechanically guarantee you compliance with the limit values below 500NOx.

 

CHP – the combined heat and power generation

 

If heat and electricity, i.e. power, are generated simultaneously in a plant, this is referred to as combined heat and power (CHP). The energy is produced directly at the place of consumption, for example in your boiler room. This means that the energy used is much better utilised. Power losses, for example from electricity or district heating lines, are effectively avoided.
The technology of combined heat and power generation achieves efficiencies of over 90 percent

 

What is combined heat and power?
Cogeneration is the simultaneous (coupled) production of electricity and heat. Cogeneration plants therefore generate power, which takes place directly on site. This is done, for example, by a small power station in the boiler room of the house, for which the heat and electricity produced is used. In this way the energy used is used much more efficiently. This means that the waste heat produced does not remain unused, which is an advantage over the power station, which discharges it via its cooling towers. Instead, it is used for heating. Losses in output, for example from electricity or district heating lines, are also effectively avoided.

 

How does combined heat and power generation work?
In cogeneration, heat and power is generated by means of a combined heat and power plant. These compact heating systems can theoretically be operated with any type of fuel (for example fuel oil, vegetable oil, biodiesel, biogas or wood pellets), with natural gas now being the most common. A combustion engine drives a generator that converts the engine’s kinetic energy into electrical energy. This produces electricity and heat at the same time.

 

This heat is transferred to the house’s heating system by means of a heat exchanger, so that it can be used effectively. In this way, hardly any energy is lost in cogeneration, and less fuel has to be used for heating and generating electricity, which saves resources. At the same time, carbon dioxide emissions are reduced, which means that cogeneration contributes to the reduction of greenhouse gases and makes a significant contribution to the success of the energy turnaround that Germany is striving for.
