Low-GWP refrigerant tool

Low-GWP refrigerants tool

The low-GWP tool helps you identify possible variations of energy efficiency in your refrigeration system when replacing the current used refrigerant with a lower GWP refrigerant alternative.

The Low-GWP tool is also available for mobile iOS devices, giving you access to the tool from the palm of your hand.


Conditions for usage of the low-GWP tool

The calculations performed by the low-GWP tool should be regarded only as estimations of the altered performance of the refrigeration system. It is generally not recommended to use drop-in or retrofit refrigerants in systems with variable evaporating temperatures. 

When using drop-in or retrofit refrigerants you must always check, and in most cases readjust, your super heat settings.

  1. Recommendation is based on the thermostatic expansion valves suitability with the retrofit refrigerant versus the old refrigerant
  2. Superheat adjustment is a guide to maintain a dry return to the compressor
  3. The smileys indicate the thermostatic expansion valves suitability at the different evaporating temperature ranges and have no reference to the possible capacity difference
  4. Capacity shows the increase or decrease in capacity of the thermostatic expansion valve using the retrofit refrigerant versus the old refrigerant
  5. Capacity changes can be managed by changing the orifice in cases where the capacity difference is very large
