Gas preheater for energy suppliers



Supply of 3 steam exhaust gas preheater modules for installation in an existing steel housing for an energy supplier in Eastern Germany.

Flue gas condenser for butchery



Replacement of a flue gas condenser after over 30 years

In 1984, a flue gas condenser made of stainless steel was manufactured and supplied by the Osnabrück-based steam boiler construction company JUMEY.

After the Economiser, which we also supplied, had already been replaced in 2010, it was now the turn of dismantling the old and installing the new flue gas condenser. Due to the fuel savings by means of the Economiser and flue gas condenser, with condensing technology, the steam boiler reaches an efficiency of over 100%.

Exhaust gas water preheater (Economiser) for breweries



A brewery in Lower Saxony has retrofitted its steam generator (5 MW) for heat recovery with an Essert-Economiser.

The steam boiler is operated as the main boiler and is supported by 2 smaller steam generators.

The Essert-Economiser saves an annual natural gas volume of approx. 700,000 m³.

Using heat cleverly - Economisers, condensers and process heat exchangers



As is well known, geckos are among the animals with the greatest diversity of species. They owe this fact mainly to their adaptability. In a figurative sense, this also applies to our products. The possibility to react flexibly and individually to needs and conditions gives our product range a variety that you can otherwise only expect from geckos.  

We, Essert Energiesparsysteme GmbH & Co KG in Duisburg, have made it our business to work daily on improvements for energy saving in industrial companies.

With more than 35 years of experience in various fields of heat recovery, we develop individual and optimal solutions for energy reduction together with our customers. We stand for competent advice, detailed planning, quality-conscious production and assembly, as well as smooth commissioning. Take us at our word.
