About Mark

Specialist in climate control since 1945

Mark has been specialising in climate management for large buildings since 1945. Under the name ‘Ingenieursbureau Gebroeders Van der Mark NV’, production and sales of bending machines and coal-fired air heaters were started. From the mid-1950s, the ‘van der Mark’ brothers increasingly focused on heating large buildings. For this purpose they built hanging gas-fired air heaters themselves. This is how the GS series came about, a unique system that is still a leader in the European heating market to this day.

This innovative strength still characterizes Mark. Mark Climate Technology now supplies a leading range of HVAC systems in the field of heating, cooling and ventilation. This means that our customers can go to one supplier for their complete climate management system.
