The infrastructure in the North-South S-Bahn tunnel in Berlin is currently undergoing extensive modernisation. We are pleased to be able to provide the necessary work safety as part of this major project. Since 15^th of January, construction phase 1 of the extensive construction project has been in progress, which includes the renewal of 2 points in the area of the "Potsdamer Platz" station and a track position correction in the area of the "Friedrichstraße" station - a challenge due to the intervention in the ballast bed caused by particulate hazardous substances.

CFT dedusting systems with an air flow rate of 9,000 m³/min are used to separate these hazardous substances.

On the 29^th of January 2024, construction phase 2 started on time, in which ventilation in the form of a classic air exchange by fans is implemented due to gaseous hazardous substances.

A total of 43 fans and 8 dedusting systems will be used on the construction site. In addition to the ventilation system, CFT GmbH - Compact Filter Technic is also providing and operating a personal location system in accordance with the requirements of the Berlin fire brigade, which enables the segment-specific localisation of people on the construction site at all times.

The work is progressing well and we are on schedule.

Dear valued customer,

we would like to inform you that, with a heavy heart, we have decided to close our roadheader division. This decision has not been easy for us, and we would like to thank you for your many years of support and loyalty.

In the interest of efficiency and concentration on our core business, we no longer see any possibility of maintaining our roadheader business operations. We are more than fully utilised with the product portfolio of the CFH Group.

We deeply regret this decision and hope for your understanding.

Nevertheless, we are pleased to inform you that the following company will act as our successor in the field of roadheaders:

ACTYON TUNNEL

C/ Progreso No.64 / 32350 A Rua (Ourense - España)

Phone: +34 9883120100

Mail:   actyon@actyon.es

WEB: https//www.actyon.es

Actyon Tunnel shares our high quality standards and will continue to provide you with roadheaders, spare parts and service.

On Friday, 16 June 2023, the time had come at Neckarstraße 23 in Marl - around 130 invited guests were eagerly waiting for the official inauguration ceremony of the new site and the launch of the new fan test stand to begin.

"The test stand at our new location is the largest chamber test stand in Europe," says Jens Kegenhoff, Technical Manager of CFT GmbH. "With it, we can test fans up to an impeller diameter of 4.50 m and a drive power of more than three megawatts in compliance with the standards."

The guests are also visibly impressed - the 7 m high and 13 m deep concrete test chamber, which is also embedded 1 m deep in the floor, towers up into the production hall like a cathedral.

In addition to introductory words by the managing partner of CFH, Dr. Reinhold Both, and technical speeches, the programme also included the official blessing of the test stand by Pastor Georg Rücker, stadium pastor of FC Schalke 04.

This was followed by the most exciting part of the programme - the launch of the test stand, the technical measurement results of which were displayed to the guests on a large monitor. But the air movement and acoustics in the hall also spoke for themselves, because depending on the type of fan being tested, large air velocities of up to over 2.5 million m³ of air per hour are generated here.

Finally, the test chamber with its flow rectifier and state-of-the-art measurement technology could be visited.

"From the afternoon onwards, all employees of our German locations and their companions are also invited to the inauguration ceremony," Dr Both announced. "Still at the old location in Gladbeck, I said that I was particularly looking forward to the first celebration in the new building."

In the framework of the BMBF-funded RePhoR joint project AMPHORE, the construction and operation of the demonstration plant at the Bottrop wastewater treatment plant (EGLV) was approved by the responsible authority under immission control law.

The owner and operator of the plant is PhosRec Phosphor-Recycling GmbH, Bottrop, a company of the water associations Emschergenossenschaft, Lippeverband, Ruhrverband, Wupperverband and Linksniederrheinische Entwässerungs-Genossenschaft.

The plant implements the patented PARFORCE-Technology® of PARFORCE Engineering & Consulting GmbH, Freiberg, as a large-scale pilot plant. With PARFORCE-Technology®, the basic chemical phosphoric acid can be obtained from sewage sludge ashes.

The CFH Group is pleased to be significantly involved in this sustainability project with the PARFORCE-Technology Cooperation GmbH (PTC).

Further information can be found in the press release of the Ruhrverband.

When engineer Hermann Deichmann opened his technical office in Bebra, Hesse, in 1947, he could not have imagined what would one day emerge from it.

75 years later, Deichmann Filter Technik is one of the technology leaders in the field of industrial dust collection for a wide range of industries.

On the occasion of the company's 75th anniversary coming up this year, DFT's sales manager published an interesting article on the subject of air pollution control, which you can download here.

This summer, CFH Holding, together with its subsidiaries CFT and PTC, will move to its new headquarters in Marl!
The new location, with more than 7,500 m² of production space - including an innovative fan test stand - will be heated and cooled by a geothermal system and supplied with electricity from its own photovoltaic system.

Last Friday, our employees were able to get an impression of the current construction progress at an "open site day".
