Sustainable refrigerant replacement app

A global trend toward sustainable refrigeration means many refrigeration and air conditioning systems must undergo a refrigerant replacement process. The Low-GWP Tool app makes it easy for service technicians to determine which new refrigerant type will work best within the system and what the consequences will be for super heat adjustment and system capacity before beginning the retrofit process.

You can start by simply entering basic information such as valve type, current refrigerant, operating range, and the replacement refrigerant.  The app will verify that you selected a low-GWP refrigerant that will work well with the existing system.

The Low-GWP Tool app helps you upgrade refrigeration and air conditioning systems with confidence and avoid causing expensive damage by choosing the wrong refrigerant.The 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.

Download it now for a quick and accurate refrigerant replacement process.

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
