70 years of experience


research & development

We are constantly looking for innovation and improvement. Our R&D team is working full-time on optimising the existing range and developing new products or applications. As a result, we have a whole range of patented products in our assortment.

We are also an official member of the NBN Committee - Working Group E 166, which is responsible for drawing up standards and guidelines relating to central heating systems and flue gas discharge systems.
Innovations are always done in close contact with our customers, so that an optimal tailor-made solution can be offered. Every problem is a challenge for us, which we take up with great pleasure.

production & logistics

Our range of products in stainless steel (single or double wall), Galva, CLV systems and the patented OTF (Opsinox Triple Flow), CSG and Opsivent systems, is produced in Nazareth (Deinze), at an ideal logistics location near the E17. Thanks to an efficient logistics organisation and a large stock, we can deliver our products quickly and on time.

Made in Belgium

production in your own country

Producing locally has the advantage that we are flexible and can react quickly. We retain full control over our production and can switch quickly. We follow up each file strictly and guarantee agreed delivery terms. And that's not all: because we do not work with intermediaries, our prices are correct and competitive.

sustainability through proximity

Sustainability is a flag that covers many things. By producing locally, we minimise transport and thus reduce our ecological footprint. But choosing to produce locally also creates employment and supports the local economy.

Made in Belgium
