History of Munters

Munters is the original innovator of climate control. Founded by ingenious inventor and entrepreneur Carl Munters in 1955, the company was built around his insights into the laws of thermodynamics in combination with an ability to translate that understanding into groundbreaking technology.

It was in 1955 that the famous Swedish inventor and entrepreneur Carl Munters (1897-1989) founded the company together with Marcus Wallenberg and two other people.

His first idea was to develop an air conditioning system based on evaporative cooling and dehumidification. The key components of the system were the desiccant wheel and the evaporative pads. 

During his lifetime, Carl applied for nearly 1,000 patents, mostly within the areas of dehumidification and evaporative cooling. Today, his legacy of innovation and engineering lives on within the company and guides our daily work.

2005 – Formation of global divisions in a new organizational structure.

Up until 2005, Munters was organized into three regions – Americas, Europe, and Asia. Those regions were in turn divided into three product areas.

The Group was divided into three global product divisions – Dehumidification, MCS, and HumiCool. That change was successful and resulted in higher gross margins and enabled a more coordinated sales process to be achieved, aimed at international customers. In addition, the new organizational structure contributed to a more concentrated product portfolio and stronger service offerings.
