More about Refrigerant Slider
Refrigerant Slider, now a part of Ref Tools, helps you quickly calculate the pressure-to-temperature ratio for more than 80 refrigerants, including natural refrigerants such as ammonia and transcritical CO2.

Refrigerant Slider also provides you with information about each refrigerant, including Global Warming Potential (GWP) and Ozone Depleting Potential (ODP). You can switch between the IPCC AR4 and AR5 values, where AR4 values are used in relation to the European F-Gas regulations.

Refrigerant Slider’s P/T calculations use extended curve–fitting models based on Refprop 10 results. You can also see both dew and bubble point for refrigerants with glide.

Streamline your workflow
Ref Tools goes beyond just providing quick access to helpful tools; it helps you save time by allowing you to track your most visited service sites and save unique settings for each one. Simplify each service call with ease.

This is just wonderful, and it's not just an app, but it's the installed and technician's best friend. Thank you again Danfoss, for making this possible. 👍👍👍👍👍👍.

★★★★★ chordarrow1 · Sep 12, 2022
Taking an HVAC course to certify as an HVAC tech and this app already began helping me glide into the industry's discipline. Very useful tool.
★☆☆☆☆ si thu · Aug 3, 2023
I can't download by cell phone, what's wrong.
★☆☆☆☆ Mario Z. · Jul 9, 2023
The only reason I don't give it a better rating is because it doesn't have Greek as a language
★☆☆☆☆ Petrus Allen · Sep 30, 2025
Not about the app’s it about updating everything Time why every month
