We are Gaiser

As a medium-sized family business with detailed industry knowledge and experience since 1928, we see ourselves as a regional market leader and full-service provider in the field of technical building equipment for commercial and residential customers.

With foresight, we have transferred knowledge of our customers' requirements into innovative and forward-looking solutions over generations. Today, more than 270 employees at the Ulm, Heidenheim and Westerstetten sites serve industrial and private customers with holistic energy concepts. We plan, build and operate technical building systems of all sizes using future-proof, efficiency-oriented technology.

We provide reliable, resource-saving and economical solutions in the fields of plant engineering, supply engineering, energy technology, air conditioning, industrial refrigeration, heating technology, sanitary engineering and control engineering.

We firmly believe that business and ethics not only belong together, but also stand as a central pillar of corporate social responsibility in a cultivated market economy. Values such as sustainability and fairness are more than just buzzwords for us. We see them ultimately as genuine added value for employees, customers and business partners.

From energy supply with heat, electricity and cooling to heating, sanitary, ventilation and air-conditioning technology to the creation of clean rooms - from a simple boiler renovation or the installation of a heat pump to a digitally controlled combined heat and power plant, the Gaiser company stands for intelligent and economical solutions from a single source. Even for complex requirements including measurement and control technology (MSR), our engineers offer customized solutions.

In other words: We offer our customers a comprehensive portfolio of all requirement areas of innovative building technology. This also includes energy contracting, which plays an important role as a logical complement to our business areas with a perfectly coordinated service package and the corresponding service & maintenance contracts.
