Reliable building services

for swimming pools, sports and industrial facilities & public buildings

Comfort, hygiene and costs in balance

We plan and deliver building services (heating, ventilation, air conditioning and plumbing) that perform in everyday use: safely, quietly and efficiently. In particular, swimming pools and sports facilities depend on the interaction of water, air and heat flows—and our teams in Graz and Sollenau bring many years of experience in this area. We deliver the same level of quality for industrial facilities and public buildings such as schools and administrative buildings. We support projects from the initial idea through to stable operation, carefully coordinating heating, air conditioning, ventilation and plumbing, and integrating heat recovery and solar hot water where appropriate.

Our services at a glance

From planning and installation to ongoing plant maintenance, we deliver a complete, integrated solution. Where appropriate, we combine heat recovery and solar hot water, optimise hydraulics and controls, and tailor the technology to your needs and budget. The result is solutions that perform today and can grow with you tomorrow.
