Ammonia is our passion - Sustainability our goal.

Developing ammonia absorption chillers and heat pumps since 1984.

Refrigeration

We are a manufacturer of turnkey ammonia absorption refrigeration systems. Every plant is individually designed to meet your specific requirements, including cooling capacity, evaporation temperature, available driving heat, and the installation space available for integration into existing cooling networks.

By utilizing waste heat or other thermal energy sources, our systems provide efficient refrigeration down to -70°C – delivering reliable, powerful, and resource-efficient cooling solutions.

Heat Pump & MVR

With tailor-made ammonia heat pumps and MVR systems, we unlock the potential of industrial waste heat. We design and deliver turnkey solutions that are precisely adapted to your process requirements – from heating capacity and temperature levels to the technically and economically optimal integration into existing energy and heating networks.

Our heat pumps efficiently convert unused heat sources into valuable process heat, producing hot water or steam at elevated temperatures. In addition, low-pressure steam can be efficiently recovered and reused through mechanical vapor recompression (MVR). This reduces energy costs, lowers CO₂ emissions, and improves the sustainability of your operations.

Engineering

From thermodynamic process analysis to the finished plant: We support our customers in the simulation, design, and optimization of complex process engineering systems. Our proprietary software enables the calculation of individual equipment such as columns, condensers, absorbers, and desorbers, as well as complete process plants and heat pump systems.

In addition, we provide tailor-made equipment and components manufactured to the highest European quality standards – efficient, reliable, and precisely adapted to the requirements of your application.

Driven by experience.
Engineered for future impact.

Sustainability

Heat recycling, by using waste heat for heating and cooling purposes and combined heat and power application are ideal implementations of ammonia absorption heat pump and refrigeration plants

Flexibility

The diverse range of designs and multi-stage absorption systems enables us to achieve a high coefficient of performance (COP) while seamlessly adapting and integrating our solutions into various processes.

Longevity

As evidence of the longevity of this technology, we have clients who have been operating their absorption plants for over 60 years.
