Our Mission

We create superior indoor climate solutions for future generations

We are ARBONIA climate. We want people to feel comfortable in the spaces of their lives at all times.

We are part of the Swiss listed group Arbonia AG, a focused building supplier. As an integrated group with competence centers throughout Europe, we convince with system solutions for heat and cool generation, heat and energy storage, heat and cool distribution as well as for ventilation and air treatment. 

We develop holistic systems that pave the way to energy-efficient, self-sufficient buildings, promote the use of renewable energies, and reduce CO₂ emissions. Our solutions cover all types of buildings and projects: residential, commercial and industrial uses, new buildings, refurbishments and upgrades.

Together, we support the energy transition in Europe and the world.

System Brands

4 well known international brands carry our system approach, therefore we call them system brands. They are our face to the customers and jointly expand their offer on the market.

CHF 576.6 million

Net revenue 2023

At CHF 576.6 million, sales in the ARBONIA climate division were 10.8% lower than in the previous year (CHF 646.2 million), despite extremely difficult market conditions.


Production sites

The ARBONIA climate production network comprises 8 highly specialized sites. With this we are always close to our customers and have an efficient set up at the same time.

Our pride

We are a European industrial company. But our roots lie in medium-sized businesses and in successful founding stories written in Germany and Switzerland, in Italy and Belgium. That is where our system brands KERMI, PROLUX, SABIANA and VASCO found their beginnings and where they rose to become leading manufacturers. We are proud of these origins. The pioneering spirit of our brands still shapes us today, both internally and externally, and makes us a group of companies that always remains human and close despite all its growth.
