Refrigeration is one of the most energy-intensive processes in modern food factories (40 to 70% of the total consumption) and plays a crucial role in both food safety, product quality and shelf-life. In line with increasing production requirements and stricter environmental regulations, the focus on energy-efficient cooling has become more central than ever before.
NH₃ DX systems could save you up to 30% on your power bill.
NH₃ DX refrigeration systems are a modern type of cooling system in which ammonia evaporates directly in the evaporator located in the area to be cooled. Unlike traditional ammonia systems, they use a precisely controlled amount of refrigerant instead of large circulating volumes.
The main advantages of NH₃ DX systems include low ammonia charge, high energy efficiency, and minimal environmental impact, since ammonia has zero ozone depletion potential and almost no global warming effect.
The systems are also less complex and well suited for compact installations.
The main challenges are the need for precise control and correct system design, as performance can be sensitive to load variations and improper settings. These issues are usually solved by using components and technology from HB Products
NH₃ DX systems are widely used in the food industry, cold storage, and process cooling, where efficiency and safety are critical. Compared to pumped circulation systems, DX systems are more energy-efficient and require less refrigerant and can be used for very large installations.
Although the system may be mechanically simpler, it places greater demands on design and dimensioning – especially of the evaporator and valves. We usually consult with one of the world leading experts Scantec Refrigeration in Australia for the detailed design.
Overall, NH₃ DX represents a sustainable and future-proof refrigeration technology that is expected to become even more widespread due to stricter environmental regulations and ongoing technological advancements.
