Half-time on the Track Construction Site in the North-South S-Bahn Tunnel in Berlin
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 15th 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 29th 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.
Inauguration of the CFH headquarters and Europe's largest fan test stand in Marl
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."

New CFH Headquarters in Marl - the Countdown is on!
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". In the future, you can reach us at the following address:
We are pleased to announce that CFH Group has taken over the sales divisions Road Tunnel Ventilation and Metro & Rail Ventilation from DLK Ventilatoren GmbH in Schöntal, Germany, with effect from 1st November 2021.
The sales activities as well as the entire order processing of jet fans and smoke extraction fans for tunnels and metros will be carried out exclusively by CFT GmbH immediately.
The acquired fan technology is based on more than 50 years of competence in the construction of industrial and smoke extraction fans from the brand manufacturer DLK Ventilatoren GmbH.
The acquisition concerns the SATM and SARM product ranges for fire protection classes F300 and F400. The tunnel jet fans (SATM series) are available in sizes from 630 to 1,600 mm and the reversible smoke extract fans (SARM series) in sizes from 1,000 to 2,500 mm.
We look forward to collaborating on projects - worldwide!
New CFH subsidiary for recovering phosphorus from sewage sludge and ash
CFH Group and PARFORCE Engineering & Consulting GmbH are pleased to announce the launch of a joint subsidiary, PTC - PARFORCE-Technology Cooperation GmbH.
Together we engineer, build and operate industrial plants for the recovery of phosphorus from effluents containing phosphate such as sewage sludge ash according to the German Sewage Sludge Act (AbfKlärV).
By the end of 2023, operators of wastewater treatment plants must submit their concept to the authorities for implementing their phosphorus recovery obligation, which will apply from 01.01.2029.
In the EU, phosphorus is considered to be a critical raw material. The production of phosphoric acid from waste streams helps to preserve natural resources and support a recycling economy.
We are looking forward to upcoming joint projects to implement circular recovery!
CFT Dry Dedusting for Roadheaders - Fully Refurbished “Down Under”
Under the current circumstances, the CFH subsidiaries around the world are especially important to us.
