Presentation about Low Charge Ammonia Systems Designed as Direct Expansion

The first cold store based on DX Ammonia and Vapor Quality Control was established 7 years ago. The system works well, and more than 20 similar projects has followed. Key to the success with DX Ammonia is Vapor Quality in combination with new liquid distribution and efficient evaporators. With the right evaporators and Vapor Quality Control you can reduce the charge by 75% and save more than 20% energy compared to state of art overfeed systems. The technology allows for further reduction of the Ammonia charge. Read more.
