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, Produktion Director Johnny Kusk Møller, and Financial Manager Svend Anker Fogh).

Behind Jysk-Fynsk Kapital are 4 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).

Today, the KE Fibertec Group is composed of four sales subsidiaries in the UK, Germany and the USA as well as Euro Air A/S. Further, the group holds two production companies, KE Fibertec Væveri (weaving mill) and Euro Air CZ.

With the acquisition of our competitor, Euro Air A/S and Euro Air CZ, the KE Group has consolidated its position as the world's largest manufacturer of textile ducting. Today, the company employs approx. 140 people, with around 50% employed at our foreign subsidiaries.

In recent years KE Fibertec has invested a lot of efforts in energy-efficient and sustainable solutions. As early as in 2012 we managed to get CradleVent® certified as the first Cradle to Cradle ventilation duct in the world.

In 2014 we introduced InTex which is an intelligent system to monitor the performance of textile ducts and when it is time for washing the customer will be alerted by email. This will provide for a healthy indoor climate and energy savings which is good for both environment and the operating economy of the system.

In 2016 KE Fibertec upgraded the total material programme so that we offer 3 unique material lines (GreenWeave, MultiWeave and ZeroWeave). As the only manufacturer in the world, KE Fibertec produces all textiles in our own weaving mill, tailored for air distribution and with full traceability.

In 2018 we introduced the TBV Designer program for order documentation, air visualizations etc.

  • 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.

    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.

    Environmental Mapping

    To minimize resource requirements and monitor our initiatives the KE Fibertec group carries out an environmental mapping process every third year. With this documentation we are able to determine if our environmental objectives have been reached and define new and ambitious objectives.

    We want to reduce our consumption of Electricity, Gas, CO2, SO2, NOx and wastewater discharge, and by comparing with our turnover we get a good picture of how well we use our ressources.

    From 2009 to 2017 our ability to save energy and minimize the environmental impacts has improved considerably which can be seen from the graphs below.

    KE Fibertec is one of few companies in Denmark to receive the Krone Smiley of the Danish Working Environment Service. The Krone Smiley is awarded to companies that work seriously to promote working environment.

  • EPD

    An EPD (Environmental Product Declaration) is an environmental product declaration that documents the life cycle environmental impact of a product.

    All material manufacturers are experiencing increasing demands to present documentation of the environmental impacts of their products, and KE Fibertec will soon be able to offer an EPD for textile ducts.

    In order to get an independent and objective evaluation we commissioned the company 2.-0 LCA consultants to be in charge of the analysis, and it was performed according to ISO 14044 and the directions herein. The report is based on a textile duct of 10 metres, Ø 500 mm diameter and with an air volume of 5,000 m3/h.

    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 documentation of the life-cycle environmental impact of a textile duct, e.g. CO2 emission (global warming), depletion of the ozone layer, release of hazardous waste etc.

    An LCA enables us to compare textile ducts with the environmental profiles of other products, and at the same time it will be a tool to prioritize our optimization strategy as to which negative environmental impacts you wish to minimize.

  • KE Fibertec weaving mill

    KE Fibertec is the only manufacturer of textile ducts worldwide to have their own weaving mill. The weaving mill was established in 1972 and is today run by Mr Frank Hansen who is the manager and third generation of the family business.

    KE Fibertec weaving mill exclusively manufactures fabrics for textile duct ventilation which is a unique situation on the global market and which gives us a valuable know-how on these materials for the benefit of our customers.

    To have our own weaving mill just across the parking lot gives us a very flexible cooperation partner who can meet our demands and requests on especially quality control and supply security.

    KE Fibertec weaving mill has very strict demands on suppliers of yarn, and all raw materials are subject to extensive input control to ensure that the permeability is unchanged even after many washes:

    • Colour may vary no more than ∆E=1
    • The textiles may shrink no more than 0,5%
    • Maximum 1% spinning oil in the yarn (standard for raw materials 3.5-7%)

    After input control the fabrics are woven on 8 looms in total - rapier looms and the more upgraded air jet looms.

    To be able again to control the shrinkage, the fabrics are heat set, i.e. heated in a special oven at 160°-190°. At this stage the material can shrink maximum 0.5% after washing.

    Before the fabrics leave the weaving mill, they undergo inspection on a light table to check for faults such as stains, and the permeability is checked as well.

    A barcode enables us to monitor the fabric which gives us full traceability in relation to production date, permeability, etc. - from reel to finished product delivered and installed at the end user.

    All materials are 100% polyester available in 3 different qualities:

    • GreenWeave (DS approved, fire retardant - B-s1, d0)
    • MultiWeave (fire retardant)
    • Ordinary polyester

    Further, we supply special materials such as Nomex and antistatic Trevira CS.

    KE Fibertec weaving mill manufactures 7 different types of "permeability" and has a range of 89 different product items.

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.
