Nexus - Scraped Surface Heat Exchangers
Heat Exchangers / Scraped Surface Heat Exchangers
Utilizing the efficient carbon dioxide as cooling medium, Nexus is a high-capacity, low-energy SSHE designed for various food products.
-
Low-energy production of crystallized fat products as mentioned below
- Test results shows that using CO2 at -10°C gives approximately 25% less energy consumption in the refrigeration system, due to better actual efficiency on the compressor system at 10°C higher evaporation temperature than for NH3 operation.
-
CO2 as refrigerant - lower investment costs for CO2 refrigeration system compared with NH3.
-
Reduction of heat transfer costs.
-
CO2 is a very efficient refrigerant which has an external heat transfer coefficient which is 2-3 times higher than that of NH3 and which will increase the total heat flux by up to 40%.
-
-
Heat recovery system possible.
-
When using CO2 as refrigerant, it is possible to install and use heat recovery systems to save energy. The heat recovery can offer useable water up to 90°C, which can be used for other purposes in the plant. Up to 70% of the energy can be recovered.
-
-
Easy inspection and maintenance
-
Hygienic design suitable for the food industry
- Optimization of floor space
