As the cooling industry continues to evolve, HVACR professionals need tools, guidance, support, and information that keep them on the cutting edge.

That is exactly what Ref Tools is all about, it is an all-in-one mobile app for air conditioning and refrigeration technicians.

Danfoss has announced that Refrigerant Slider, the popular P/T calculation app that has over 2 million downloads, will transform into Ref Tools.

HVACR professionals can download Ref Tools to automatically get all the new tools and features or access it via your browser at

Ref Tools includes five of Danfoss’s most popular and useful air conditioning and refrigeration tools:

Refrigerant Slider

While Refrigerant Slider is changing into Ref Tools, it will retain all the core functionality that made it a hit with millions of installers around the world. Users can still find Refrigerant Slider within Ref Tools and use it to quickly calculate pressure/temperature ratios for over 80 refrigerants. 

Low-GWP Tool  

Low-GWP Tool helps users find and compare climate-friendly refrigerants for retrofitting by checking compatibility with the cooling system’s TXV. 


Troubleshooter helps users identify and compare symptoms in a refrigeration system that is acting up. Once they identify the issue, Troubleshooter also recommends solutions to try.

Spare Parts 

Spare Parts lets users access and order an extensive list of Danfoss spare parts and service kits for industrial refrigeration applications, right from the job site.

Magnetic Tool 

Magnetic Tool helps users test and troubleshoot solenoid valve coils quickly and easily.  

Ref Tools lets users track their most visited service sites and save unique settings for each one. Users can also access Danfoss’s popular Chilling with Jens podcast directly in the app, giving them a chance to learn something new about refrigeration while on the go.

Danfoss Cooling director of concepts & content, Janni Koie, said Ref Tools is an exciting next step into the future of digital tools in the cooling industry.

“By putting helpful tools in our customers’ hands, we hope to make their daily tasks in the field much easier so they can save time,” Koie said.

“Ref Tools includes more than the tools they already know so well – and there’s more coming down the road. We can’t wait to reveal what’s next.”
