Dry Condensing
The basic principle of modern dry condensing is to capture all the low pressure, condensable vapors generated in a given process by freezing them on cold surfaces at the full process vacuum. By employing this principle it is unnecessary to compress the vapors to atmospheric pressure for condensation at ordinary cooling water temperatures, thus vastly reducing energy consumption.
Niro's Atlas group is a worldwide leader in freezes drying equipment. Condensing under high vacuum is a vital part of modern freeze dryers. The condensing knows how for freeze-drying is the basis for the development of dry condensing.
Advantages of the Atlas dry condensing plant:
- Low energy consumption: The energy usage is only 10-20% of traditional steam ejector systems.
- Reduced steam load: No motive steam is used, freeing boiler capacity.
- Reduced pollution: Volatile material carried over from the process contained in the small volume of water is condensed from the process steam, thus allowing easy separation. There is no additional condensate from motive steam.
- Low water consumption: Total water consumption is reduced to one tenth of a percent of the of steam ejector systems.
Atlas dry condensing systems have been installed in more than 40 plants in 20 countries worldwide, reducing energy costs and waterborne emissions.
