What is Low Superheat and when is it relevant?

Low Superheat improves evaporator efficiency by ensuring more refrigerant is used for cooling rather than superheating.

Low Superheat allows the evaporators to run with very low superheat settings without the risk of liquid CO2 returning to the compressors. Typically, the evaporation temperature can be increased by around 4–5 Kelvin, providing energy savings of around 10%.

It is recommended for units below 100 kW.

Benefits:

• Up to 10% energy savings

• Up to 24% more cooling capacity

• Less defrosting

• Improved system stability
