History of eferest

eferest has always moved with the times in the field of pressure vessel construction since taking over from Ulrich Blaschke in 1993. In line with the motto, if you rest, you rust, we continuously invest in our employees, our machinery and our product portfolio.

Originating in 1939, we have decades of experience with our products. The expertise we have gained from this and our numerous certifications make us a reliable, experienced and unique partner who will be happy to work with you on your pressure packaging needs.

2016

A new roller moves into Hall 5 in Wilnsdorf-Wilden. This can bend a clear diameter of 410 mm with a wall thickness of 70 mm over 3 metres. We also acquire a 3D pipe cutting machine and automatic submerged-arc machines with two-wire technology for welding.

2015

We invest in a new roller in Wilnsdorf-Wilden, which can process steel with a wall thickness of 125 mm over a length of 3 metres to a light diameter of 580 mm. We also acquire a 2D CNC flame cutting machine with oxyfuel and plasma processes.

2011

The relocation of the administration from Wilden to Anzhausen changes the location of the company. This consolidation brings the main production facility and administration together in one compact location. The new, modern office building has a clear, uncluttered appearance thanks to its linear shape and its bright atmosphere with high-quality office furnishings ensures pleasant workplaces.

2010

The expansion of the company at the Anzhausen site leads to a reorganisation of the production process. The entire series production, as well as incoming goods and goods inspection, are relocated to the new site. In order to expand our vertical range of manufacture, we start surface treatment and paint our vessels ourselves for the first time. Prefabrication, rolling and longitudinal seam moulding remain in Wilden.

2008

Eferest GmbH continues to grow. We build a second production hall in Anzhausen. Special solutions and high-pressure vessels are manufactured in this hall. At the same time, Eferest GmbH continues to develop on the international markets. The ASME VIII, Div.2 and SELO China certifications provide the best conditions for the company's expansion.

A further production facility is set up at the Wilnsdorf-Anzhausen site for series production.

A milestone. Eferest Stahlblechbau GmbH has entered the production of high-pressure vessels up to 120 bar.

Production of individual pressure vessels is started in Hall 1. The production programme in the area of pipe components is improved and expanded.

1993

Ulrich Blaschke joined the company on 1 April 1993 at the age of 29, immediately after completing his studies. He restructures the company and creates a future-oriented perspective by shutting down the steel construction division and focussing on special tank manufacturing, raw mould construction and high-pressure vessels.
