Nexus - Scraped Surface Heat Exchangers

Product Type:
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.

Supporting production output of shortening of up to 20,000 kg/h, the scraped surface heat exchanger GS Nexus offers a number of unique benefits:
  • 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
