More than 30 years of Experience in thermal plant design
1985 The Beginnings
Starting with studies in Physics at Technische Universität München, Jürgen Scharfe has been active in the field of Absoprtion technology. During the period of Ph.D. at the institute of Professor Dr. G. Alefeld a collaboration with ENTROPIE S.A. , at that time a private owned company based in Saint-Germain-en-Laye was established.
1989 First joint projects with ENTROPIE S.A.
The first joint studies finally resulted in the design an construction of the world's most energy efficient sea water desalination plant using a 14 stage evaporator and a 2 stage absorption heat pump in Almeria / Spain. After this succes ENTROPIE received a couple of orders for innovative absorption units in Germany.
1995 foundation of ENTROPIE GmbH
A 100% daughter company was created to cover the market in Germany, J. Scharfe became managing director.
2008 Separation of the actiivities form ENTROPIE S.A. now part of Veolia Group
By 2008 Jürgen Scharfe bought the shares of ENTROPIE GmbH including the entire know-how of Absorption Technology. Entropie GmbH was renamed INVEN Absorption GmbH.
2013 Research for Partners
With increasing size of projects the company faced the need to increase its financial background. Especially the size of the projects in the petrochemical sector reached a size which was no more manageable with current size of the company.
2014 Sale of the Absorption acitvity to CNIM S.A. Paris
Finally this challenge was resolved by selling the entire activity of design an manufaturing of absorption equipment to CNIM S.A. Pairs. CNIM has very solid financial background and can execute these projects form the design , procurement , fabrication and aafter sales with in-house cpacaitites.
2014 Renaming the Company to JS Energie & Beratung
INVEN Absorption GmbH will continue to exist as an independant, 100% family owned company but will no more design and sell absorption units and therefore changed the company to JS Energie & Beratung.
This activity is focused on the development of industrial absorption projects in industry on a worldwide scale providing unbiased consultancy to end client and design engineers. It includes all stages from feasibility studies through establishment of RFQ documents to validation of tenders in the name of the end user.
Besides this commercial activity, Jürgen Scharfe is an active member of ASHRAE and is chair of Ashrae Handbook Section 18 Absorption Equipment.
