By using the environmentally friendly refrigerant NH3 (R717) with a GWP of 0, ammonia is the long-term and sustainable solution for many refrigeration applications. NH3 has the best possible performance in heat transfer, which is useful for high power applications. Therefore, ammonia is mainly used in industry, but also for cold water solutions and storage cooling up to the megawatt range. All cooling requirements are performed safely, efficiently and in compliance with the applicable standards and laws. In addition, NH3 refrigeration systems are subsidised in accordance with the BAFA guidelines for the promotion of refrigeration and air conditioning systems.
