Pressure-to-temperature calculation app for 80+ refrigerants 

Update: Our Low-GWP Tool, Troubleshooter, and Spare Parts apps have now been integrated with Refrigerant Slider. You can still access all the features you’re familiar with in Refrigerant Slider, but with additional functionality and convenience. 

Click here to access the browser version of all four tools.

Refrigerant Slider is an essential tool for HVACR professionals, helping 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.

The Low-GWP Tool, Troubleshooter, and Spare Parts apps from Danfoss have now been integrated with Refrigerant Slider. You can access them and get enhanced features by updating to the latest version of the app.  

Low-GWP Tool 

Low-GWP Tool helps you find and compare compatible, climate-friendly refrigerants for refrigeration system retrofits by checking compatibility with the TXV. 


Troubleshooter helps you navigate issues in refrigeration systems, so you can quickly identify symptoms and get recommended solutions.


Spare Parts

Access and order an extensive list of Danfoss spare parts and service kits for industrial refrigeration applications—right from your smartphone.  


How to use Refrigerant Slider 

On the left side of the screen, an interactive slider helps you quickly set the pressure or temperature reference. On the right side, you can find the precise pressure and temperature based on your input. You can also type in a precise pressure or temperature reading and Refrigerant Slider will instantly give you the corresponding figure and move the slider for visual indication.  
You can easily switch pressure and temperature units between metric (SI) and imperial units as well as between gauge and absolute pressures as you see fit. 



The Refrigerant Slider app

Try the web version

The Refrigerant Slider tool is also available in a web version, enabling you to use it straight from your browser.


In this video, you’ll learn how to use the app by comparing two refrigerants, R407F and R507. You’ll also get a walkthrough of all the different functions you can perform in the app and see the information you can get about each refrigerant, including class, GWP, ODP, superheat, and more.
