Specialist engineering cooling solutions
For over three decades, JAEGGI has been the specialist for hybrid and adiabatic cooling technology. But our real strength lies in how we work: we listen to your needs, understand operational challenges and engineer solutions that deliver reliability, performance and sustainability. As part of the global Güntner Group, we bring together proven heritage, leading-edge innovation and a highly personal, consultancy-led approach to every project we deliver.
Cooling with purpose
We set the benchmark for responsible cooling engineering by enabling reliable performance while improving energy, water, and resource efficiency. By integrating intelligent heat rejection and waste-heat utilization, we help infrastructure operate more efficiently today while supporting resilient, future-ready cooling systems.
What makes JAEGGI different
A consultancy-led approach
Engineered for constraints
Tailored when it matters
Efficiency without compromise
Sustainability, designed into every decision
Sustainability at JAEGGI is not an add-on or a single metric. It is built into how we engineer, select and configure every cooling system, balancing performance, efficiency and long-term environmental responsibility from the very start of the design process.
The IMPACT Framework
To support more informed decision-making, JAEGGI applies the IMPACT framework as part of system selection and evaluation. IMPACT translates complex engineering and sustainability considerations into a clear, comparable view, helping customers understand how different design choices influence efficiency, resource use and long-term performance.
Rather than relying on generic claims, IMPACT supports transparent discussion around trade-offs, enabling solutions to be aligned with both operational priorities and sustainability goals early in the project lifecycle.
Our people & how we work
Our customers value our engineering depth and our personal approach. Every project is guided by experienced specialists who stay closely involved from first conversation to commissioning. We work collaboratively, as consultants, engineers and partners, to ensure the solution truly meets your objectives.
Our technology heritage
JAEGGI pioneered hybrid dry cooling technology and continues to evolve it through innovation in performance, hygiene, efficiency and lifecycle durability. Today, our systems are trusted in data centres, manufacturing plants, airport facilities, research institutions, hospitals and energy-intensive environments worldwide.
Part of the Güntner Group
As part of the Güntner Group, a global leader in heat exchange technologies, we benefit from international reach, world-class R&D and decades of experience. Yet JAEGGI occupies a unique niche within the group: we are the specialists for complex, project-driven cooling solutions where precision, customization and consultancy matter most.
