Vitobloc 200 EM-20/39 Combined heating and power plant with maintenance intervals up to 6,000 hours The Vitobloc 200 EM-20/39 is Viessmann’s new mini CHP station with a long maintenance interval of 6,000 hours.

Heat produced as a by-product of generating electricity in central power plants can normally not be further utilized. Because there are typically no customers nearby to use this heat, it is simply released to the atmosphere. As a result, efficiencies of not even 40 percent are achieved.

Decentrally located combined heating and power (CHP) plants in contrast have the advantage that their heat can be captured and used, allowing them to achieve efficiencies of more than 90 percent.

Maintenance intervals of up to 6,000 hours

Viessmann’s new Vitobloc 200 EM-20/39 provides 20 kW of electrical output and 39 kW of thermal output, making it espe- cially well-suited for residential complexes with 30 to 50 units, hotels, retirement homes and commercial enterprises. for a car in comparison would be Flexibly adjusts to Extensive standard features 360,000 kilometers before any requirements of utilities The four-cylinder gas engine of the engine maintenance had to be companies Following test start-up at the Vitobloc 200 EM-20/39 is specifi- performed. production plant, Vitobloc 200 CHP cally designed for stationary Utilities companies have different units are delivered as compact operation and is particularly robust requirements for connecting CHP modules ready for operation and and reliable.

Karl Duschek A champion of clarity and conciseness

One of the most important German graphic designers of our time passed away on November 1, 2011 in Stuttgart at the age of 64 following a short, serious illness. The boundaries between design and art were fluid for Karl Duschek. Together with ingenious constructivist Anton Stankowski, whom he succeeded 13 years ago, he developed striking com- pany logos, including for Deutsche Bank and German retail group Rewe. Both artists have had a significant impact on Viessmann’s visual identity.

Cooperation with Anton Stankowskii

Karl Duschek was born in Braun- schweig, Germany, in 1947. After his apprenticeship in lithography, he studied at Braunschweig University of Art.
