The foundation of KE Fibertec goes back to 1963 when Keld Ellentoft (KE) began manufacturing filterbags for industry. In 1996 KE Fibertec was founded in a management buyout by two leading staff members, Henning S. Jensen and Carsten Jespersen. In March 2007 Henning S. Jensen sold his shares to Jysk-Fynsk Kapital AS, and Sales Director Carsten Jespersen was appointed new managing director.

KE Fibertec is owned by Jysk-Fynsk Kapital AS (70%), Elkær Invest A/S (10%), and KE Pulje ApS (20%). KE Pulje is owned by the day-to-day management group of KE Fibertec (Managing Director Carsten Jespersen, Production Director Johnny Kusk Møller, and Financial Manager Svend Anker Fogh).

Behind Jysk-Fynsk Kapital are four well-known Danish family foundations: Genua A/S (Primo Group), Hoffmann Esbjerg Holding A/S (Arovit Petfood), Elkær Invest A/S (Tvilum A/S), and Vald. Birn Holding A/S (Vald. Birn A/S).

The KE Fibertec Group currently consists of eight subsidiaries, four sales subsidiaries in the UK, Germany and the USA in addition to Euro Air A/S. In addition, there are three production subsidiaries, KE Fibertec Væveri in Denmark, Euro Air CZ and Air Distribution Concepts in the US, and in 2024 a new member joined the KE Group, KE Techmon, a Danish-based installation company.

Through controlled growth and acquisitions, KE Gruppen has consolidated its position as the world's largest manufacturer of textile ducting.

KE Gruppen currently employs 150 people with approx. 55 employed in the Danish companies and the rest in the foreign subsidiaries. In recent years, KE Fibertec has invested heavily in energy-friendly and sustainable solutions.

Already in 2012, CradleVent® was approved as the world's first Cradle to Cradle certified ventilation duct.

In 2016, KE Fibertec upgraded the entire material programme to three unique material lines, GreenWeave, MultiWeave and ZeroWeave. As the only manufacturer in the world, all textile materials are produced in our own weaving mill - exclusively for air distribution and with full traceability.

In 2018, we introduced the TBV Designer software for order documentation, air visualisations, etc.

In 2019, we established our own in-house laundry, which in 2023 was upgraded to triple capacity, and together with our new service and maintenance department, we can now offer our Danish customers a complete service agreement that includes pick-up, dismantling, washing and re-installation of the freshly washed textile ducts and/or storage of spare kits. Contact your local KE partner for more information on service and maintenance.

KE Fibertec AS has for many years worked strategically with sustainability based on the following four pillars:

  • Environment and energy

    At KE Fibertec we care about the environment and about energy. We want to make as little harm to the environment as possible both in production and in transportation of our products. Therefore, we have launched a number of in-house energy-saving initiatives to limit the CO2 emission.

    To show concern for the environment is to show responsibility and sustainable considerations. On top of that, it is good business.

    KE Fibertec is certified acc. to ISO 14001 and our textile ducts are based on Oeko-Tex® Standard 100 certified yarns

    Cradle to Cradle

    We have achieved a Cradle to Cradle certification of CradleVent documenting the sustainability of the product.

    CO2 neutral electricity from wind turbines

    All electric power consumed by KE Fibertec and our weaving mill (KE Fibertec Væveri) is generated by wind turbines. Consequently, it is CO2 neutral and not harmful to the environment.

    EPD

    The EPD is an environmental product declaration that documents the life cycle environmental impact of a product.

    By choosing textile ducts you are doing something good for the environment:

    • Because of the low weight of textile ducts the fuel consumption during transport (and therefore the CO2 emission) will decrease remarkably compared with transporation of traditional steel ducts

    • A properly dimensioned fabric system is able to function optimal at a lower pressure drop than conventional ceiling diffusers

    • The air distribution with textile ducts is better, and it is therefore possbile to offer a solution that does not take in "unnecessary" air. This results in energy efficiency - and a better indoor environment.

  • EPD (Environmental Product Declaration)

    An EPD is an environmental product declaration that documents the environmental impact of a product throughout its life cycle. An EPD must be third-party evaluated.


    KE Fibertec EPDs are developed in accordance with the requirements of EN 15804+A2:2019 and verified by IBU, Germany.


    An EPD is a summary of an LCA (Life Cycle Assessment), which is documented in a more comprehensive report. The report is an in-depth and verified examination of the environmental impacts throughout the lifetime of the textile duct. KE Fibertec offers EPDs for GreenWeave and MultiWeave solutions and the verified reports can be downloaded here.


    Along with the new EPDs, KE Fibertec has launched a new EPD generator where we can offer dynamic calculations per project. In the verified calculations, the environmental footprint of the entire product is GWP-Total in kg CO2 eq per 1 kg of total textile duct including suspension rails, accessories and packaging.


    The environmental footprint is typically provided for the following conditions:

    • Cradle to gate (A1-A3) For direct product comparisons
    • Full lifetime (A1- C4) Lifetime calculation
    • Reuse (D1-D3) Circularity

    KE Fibertec offers full EPD documentation regardless of whether it is a quote or an order.


    It is important to ask your supplier to make a complete calculation for the entire product and not just the textile. In a typical textile duct, the textile surface only accounts for 34-35% of the total environmental impact.

    KE Fibertec only offers an EPD for the complete duct including installation and accessories, i.e.


    1. Complete transparency
    Complete product-specific third-party verified EPD (everything included: Textile material, suspension rails, accessories, packaging)


    2. Project-based EPD generator
    Everything tailored to the project at hand


    3. Extra sustainability points in building certifications such as DNGB and BREEAM
    Ask for KE Fibertec's updated documentation


    4. Lower carbon footprint with KE Fibertec's TBV solutions
    Achieve 5-6 times lower carbon footprint with KE Fibertec TBV solutions compared to *traditional steel solutions (Cradle to Gate (A1-A3) and lifecycle (A1-C4))
    *)Compared to the industry association VELTEK's EPD for round spiro ducts


    5. Take Back solutions
    Take advantage of KE Fibertec's Take Back solutions and recycling of all production waste. Part of our products at no charge

  • KE Fibertec weaving mill

    As the only manufacturer of textile ducting in the world, KE Fibertec has its own weaving mill. The company dates back to 1977 and is run by Frank Hansen, the third generation of the company. In 2020, we expanded the weaving mill with our own in-house laundry. In 2023, the laundry capacity was tripled and a new extension was built to house the KE Fibertec Group's material innovation centre.


    KE Fibertec Væveri is the only company in the world market that exclusively weaves materials for textile based ventilation. This gives us a unique opportunity to select raw materials that give our textile materials the exact properties we want and that benefit our customers. This applies to properties such as shrinkage stability, colour fastness, fire properties that do not require leaching of spin oils before testing, High Dust Holding Capacity (longer washing intervals) and, not least, uniform materials with a completely uniform airflow per m2 even after repeated washing.

    All materials are woven in Cradle to Cradle certified yarns, which is part of our circular business model. To ensure high colour fastness and minimum water consumption in the dyeing process, we only offer yarn-dyed materials that - compared to conventional piece dyeing - offer the benefit of approximately 65% less water consumption in the dyeing process. The textile industry worldwide is both famous and infamous for using even very large amounts of water resources for dyeing. At KE Fibertec, water consumption for dyeing is almost non-existent, and we can offer our entire colour range - including dark colours - with the same low environmental impact.

    In addition to GreenWeave and Multiweave, which are woven in 100% polyester (Cradle to Cradle approved) and available in up to seven different variants (air permeable), we can supply special products such as Nomex and anti-static Trevira CS.

Design

To be able to dimension a textile based ventilation system, it is important to understand a number of essential parameters and concepts.

A textile based ventilation system is not fundamentally different from conventional ventilation systems, but there are a number of key points where it is important to be extra cautious, such as pressure conditions, pressure loss, pulsations, pressure impact, entrainment, air velocities and sound.

It is very obvious when a textile based ventilation system has been dimensioned incorrectly because the ducts will be oval and "sagging" when you look at them. The difference in the static pressure between two parallel ducts may be quite considerable too. This not only has an impact on the aesthetic impression, but also on air distribution to a great extent.

If the pressure distribution is inappropriately uneven this can cause draught problems below and around the duct with the highest static pressure, while in the opposite case, the air quality will be poor in the area where the static pressure (and therefore the volume of air) is not sufficient.

Further, there may be a risk of pulsations in the textile material that may damage not only the textile material but also the suspension material.

Design and flow visualization with TBV Designer

KE Fibertec has developed the TBV Designer program in order to be able to document technical data supported by know-how.

The program enables flow visualizations and documentation of the solution. It also features freedom of design, spatiality, and information on velocity within the occupied zone height.

See more in the film below showing the dimensioning of Water & Wellness Flintholm




You can also design and calculate textile ducts directly in the MagiCAD Ventilation product database. 

Dialogue & Quotations

KE Fibertec has developed a number of tools and services which our customers can choose to use throughout the entire project process. Our services are graded so that customers can decide themselves which ones they do and don't want. Our opinion is that no two jobs are the same and no solution is standard. Consequently, the documentation and level of detail need to be adapted to the requirement and each individual project.

Our service can be split into two categories:

  • Quotation and design
  • Exteneded project documentation


Our quotation and design processes are described in detail in our ISO 9001 quality assurance system. This ensures that we prepare the basis for the quotation and the quotation itself according to the standardised guidelines, making sure that the customer's requirements are specified and documented in sufficient detail.

KE Fibertec puts large emphasis on ensuring that the final solution is designed correctly even at the quotation stage. After all, it is not only about ensuring that the textile based ventilation system works properly, but also, to just as large extent, that the customer's indoor climate requirements have been met. This is why we ask about the system's functional requirements and the requirements for the indoor climate at the quotation stage.

All the calculations are proven using our unique software TBV Designer, which is offered to all our customers, regardless of the size of their project and, of course, free of charge.

Of course detailed mounting and maintenance instructions are included. For complicated TBV systems we also include AutoCad drawings.

As part of our extended project documentation we offer full-scale measurements in our laboratory, on-site measurements and CFD simulations.
