Natural Refrigerant ammonia

Ammonia has been used as a natural refrigerant in industrial refrigeration plants for over 100 years. It is a colourless gas liquefied under pressure with a pungent smell. As a refrigerant, ammonia is known under the refrigeration designation R717 and is produced synthetically for use in refrigeration technology.

Ammonia has no ozone depletion potential (ODP = 0) and no direct greenhouse effect (GWP = 0). Due to its high energy efficiency, its contribution to the indirect greenhouse effect is also comparatively small. Ammonia is conditionally combustible. However, the ignition energy required is 50 times higher than that of natural gas, and without a supporting flame ammonia will not continue to burn. In conjunction with ammonia’s high affinity to humidity, this has led to its classification as hardly inflammable. Ammonia is poisonous, but has a characteristic pungent smell with a high warning effect and can be perceived in the lift from a concentration of 3 mg/m³. This means that the warning effect occurs long before a harmful concentration (> 1,750 mg/m³). Ammonia is also lighter than air and therefore rises quickly.

We have always assimilated engineering science and thermodynamics optimally in the various manufacturing processes.

Thermodynamicists,mechanical engineers and welding engineers define the dimensioning, design and construction of customised heat exchanger panels and systems in materials ranging from mild and austenitic steels through to titanium, and ensure successful distribution of their work worldwide.

In doing so they fall back on production engineering expertise and calculations developed in the course of the past hundred years that are still being continuously optimised in an ongoing process.

In the perception of our customers, the Buco product stands for:

Technical and process-oriented consulting
Thermodynamic efficiency
Quality and longevity
