To Desotec

Market trends and drivers

The overall activated carbon filtration market is expected to grow mid-single digit, driven by increased regulation, CSR awareness, growing industrial output, and further penetration of mobile filters. The activated carbon filtration market in Europe can be split into mobile and fixed filtration. The mobile segment, in which Desotec is active, is growing significantly faster. Advantages of the mobile solution include: minimal upfront investments required for the customers, modular up- or down-scaling of filter capacity, plug-and-play concept with closed systems avoiding carbon handling on-site, no maintenance costs for the customers, and minimal downtime of the customer's operations.

Investment potential

Desotec's strong position in a growing market, in combination with a high share of recurring revenues, makes it an attractive investment. EQT VII is keen to support Desotec's growth both organically and in-organically.
