Group of companies

Interduct is a group of companies. That means we do not provide products or services ourselves, but enable our companies that do, to develop and grow further. We do this by giving them the knowledge, experience and finance they need to serve you even better.

We believe it is important that companies are able to grow from their own strengths and authenticity, which is why we only work with companies that feel "at home" with Interduct. That works best for everyone. All the choices we make are based on the Interduct house, which describes, among other things, our values, goals and dream ambition. Would you like to find about the options? Please feel free to contact us.

Our core values

This is what we stand for

Core values are usually deeply rooted in the organisation; you don't change them overnight. We also believe that you do not "teach" values, rather our focus should be on finding and linking up with companies and people who naturally pursue these values. This benefits everyone.

  • Collaboration
  • Autonomy
  • Trust
  • Growth
  • Respect

Our companies

We believe that collaboration makes us strong. Each Interduct company is unique and has its own story, a story that goes beyond mere ventilation. However, there are also some important common factors. Therefore, we deliberately choose to work only with companies that work with similar core values. Because we are all similar and speak the same language, we achieve the best results. Our DNA also has similarities, as ventilation, to a greater or lesser extent, is in the bloodline of every company in our group. Whether you need to manufacture, install, construct, renovate or maintain ventilation; you will find what you need at Interduct. Together, we work towards our dream ambition: providing a sustainable, healthy and comfortable indoor climate for companies and private individuals throughout the Netherlands and beyond.

Interduct timeline

2025
Acquisition of VentilatieService
With an eye on the future sustainability of their business, the owners enter discussions with Interduct. It doesn't take long before they are certain: this is exactly the group they are looking for. As a result, they decide to join.
2024
Acquisition of AirTotaal Group
The AirTotaal Group wishes to accelerate the growth of their "brainchild." Since there is an immediate connection and Interduct also sees benefits in a partnership, they decide to proceed with a full acquisition.
2023
Full acquistion of BJ-Lupron
Interduct had been one of BJ-Lupron's shareholders since 2007. Now that the owner was coming up to retirement, he wanted to transfer the remaining shares to us too. This means that BJ-Lupron is now fully owned by Interduct.
2023
Sale of AT Group
After long-term collaboration, the director/co-owner of the AT Group wanted to take (early) retirement. Following in-depth discussions, it was agreed to sell the company to a party who was able to focus on further growth in Belgium.
2023
Partnership with IceLake Capital
With the aim of further growth, Interduct entered into a partnership with IceLake Capital. Together we are working on spreading sustainable, healthy and comfortable indoor climates for everyone, while retaining our autonomy.
2023
Takeover of Chris Steijvers Electro
Driven by the need for greater knowledge of electrical technology, Interduct got in touch with Chris Steijvers Electro (CSE), who wanted to expand and innovate. The takeover helped both parties move forward, so it was quickly arranged.
2023
Move to Nederweert
By now the Interduct Groep consisted of 15 companies and the head office was literally bursting at the seams. ComfortServices, VentTrade and Tops moved out to the new building in Nederweert and Robé and Rodrie swapped Haelen for Ittervoort
2023
Setting up RenovAir
The renovation division of ComfortServices was growing fast. So fast, in fact, that it was time that it struck out on its own. The companies continued to operate separately, under the names ComfortServices and RenovAir.
2022
Acquisition HAS en FiltryAero
After years of collaboration we pooled our resources and Interduct took over Home Air Solutions (HAS) and FiltryAero. This step fitted perfectly with our ambition to grow in Central and Eastern Europe.
2021
Setting up Intovent
The consumer market was showing increasing demand for ventilation (products). That is why some Interduct companies got together and created a B2C online shop. This was given the name Intovent, because Interduct is "into vent(ilation)".
2021
New shareholders
With the takeover of Tops there were again two new members in the team of directors: Tim Coppens and Ruud Coppens, both experts in e-commerce and sales. This brought the number of board members to five.
2021
Takeover of Tops & WTW-filtersOnline
Growing the companies while he took a back-seat, that was the plan of the owner of Tops and WTW-filtersOnline. Cue the entry of Interduct. It worked well from the start, so a takeover felt like the natural next step.
2019
Takeover of Robé & Rodrie
The owner of Robé and Rodrie was looking for someone suitable to take over and continue his production company (Robé) and building services company (Rodrie). Following the necessary negotiations and a firm handshake, Interduct took over the companies.
2019
Acquisition Velegro
Interduct wanted to build up its market position in the Randstad area, and got in touch with Velegro via Megaduct. They also saw the benefits of collaboration, and decided to sell off their ventilation department to Megaduct.
2016
New shareholders
The director alongside Frank Huis resigned. Therefore new directors were appointed: Joyce Philips because of her background in Lean Management and finance, and Ivo Hanssen because of his experience with building services engineering.
2015
Setting up PRO61
Interduct wanted to continue to serve the utilities market and decided, with two partners, to make a new start with Brema Air. This time under the name PRO61, a reference to Chapter 61 (ventilation) in the building regulations.
2015
Setting up Interduct Products (2)
There was heavy demand for special items and bespoke work. That was why Interduct bought the Brema Air machines back from the administrator and restarted production. The new production company was (once again) called Interduct Products.
2014
Bankruptcy of Brema Air
The takeover of Brema Air sadly did not create any winners. A legal ruling led to such high costs that continuing with Brema Air could no longer be justified. A difficult, but necessary decision.
2014
Merging production
Interduct wanted to work (even) more efficiently. That is why it was decided to merge the installation activities of Meercox and the manufacturing of Interduct Products (formerly IBB) with Brema Air. The name Brema Air was retained.

2013
Takeover of Brema Air
There was crisis in the air, and Brema Air went bankrupt. Based on its desire to be a market leader in the utilities sector, Interduct submitted a bid for the assets of Brema Air. Successfully. The company was taken over, together with a large number of employees.
2007
New shareholder
The directors let it be known they wanted to move on. To make sure that "their" Interduct would carry on safely, they looked for (and found) a suitable successor. From January 2008 onwards, Frank Huis became a shareholder.
2007
Setting up VentKlima
The limits to growth were once more extended. Literally. This time in the north-east of the country, where Interduct worked with the representative of a supplier to create a third building services company: VentKlima.
2007
Acquisition BJ-Lupron
Interduct was looking for more capacity in the south and saw opportunities in a collaboration with BJ Lupron, previously Bemelmans Jongen. What followed was a series of useful discussions and finally a partial takeover.
2001
Takeover of AT Group
Interduct also wanted to provide the Belgian market with a suitable ventilation solution, and got in touch with the AT Group, consisting of an installation company and (later) also a commercial company. This led to a partial takeover.
2000
Takeover of IBB Luchtbehandeling
Partly thanks to recent developments, there was a growing desire to have an in-house manufacturing company. As a result, Interduct got in touch with IBB. Soon afterwards, they shook hands and signed a takeover agreement.
1999
Setting up Comfort Services
The sale/purchase and installation of spare parts for ventilation are inextricably linked. Which is exactly why ComfortServices was set up; this company focuses on services, maintenance and renovation.
1999
Setting up VentTrade International
Installers and retail customers were looking more and more often to buy spare parts, but at the time Interduct was not (yet) able to supply them. This led to the idea of setting up a retail company and soon afterwards VentTrade was created.
1998
Creation of Megaduct
During a discussion with someone who worked with a competitor, a major wish was put on the table: setting up a new Interduct company like Bemar in the central Netherlands. Shortly afterwards we got together and jointly set up Megaduct in Loosdrecht.
1996
Move to Ittervoort
The Board felt it would be more efficient to have all the companies in one place. The place they chose was Ittervoort. After two new buildings were constructed Bemar, Meercox and the LTL factory moved to the new (headquarters) location.
1995
Takeover of Luchttechniek Loosdrecht
Luchttechniek Loosdrecht (LTL), consisting of ROX Luchtbehandeling and Loosdrechtse Luchtkanalen, was up for sale. Interduct took over the latter. Their activities continued to be based in the building in Loosdrecht.
1992
Creation of Interduct
After a rather turbulent period, Bemar and Meercox (factory) shook hands and joined forces. This collaboration led to the need for a holding company. This was named "Interduct", based on the English word for air duct.
1984
Setting up Bemar
There were changes afoot in an installation and production company in Limburg. This led to two of its employees setting up a similar company of their own: Bemar, named for the loves of their lives, Betty and Marlies.
