Danfoss Ref Tools: The Free App Every Refrigeration Tech Needs — and Why Keep Supply is Built Right In

If you work in refrigeration or HVACR, your job demands fast decisions and accurate information — usually at the same time, usually on a job site, usually under pressure.

Danfoss built Ref Tools to put every resource you need in the palm of your hand, and Keep Supply is proud to be the distributor powering parts ordering inside the app.

Here's what Ref Tools does, why it matters, and how to get it.

What Is Ref Tools?

Ref Tools is Danfoss’s all-in-one mobile app for air conditioning and refrigeration technicians, bringing together five essential tools that help make every job easier – from system diagnostics and refrigerant data to troubleshooting and performance optimization. 

The app is free, available on iOS and Android, and also runs in any desktop browser at reftools.danfoss.com — so no smartphone required.

The Five Tools Inside Ref Tools

1. Refrigerant Slider
The feature that started it all. Refrigerant Slider gives you instant pressure-temperature ratios for more than 80 refrigerants. Whether you're charging a system or verifying operating conditions, this replaces the laminated chart you've been carrying since certification.

2. Troubleshooter
When a system isn't behaving right, Troubleshooter helps you work through it methodically. Enter the symptoms you're seeing, and the tool identifies likely causes and recommends solutions — turning diagnostic guesswork into a guided process.

3. Low-GWP Tool
As regulations evolve and customers push for more sustainable refrigerants, the Low-GWP Tool helps you identify climate-friendly alternatives and check TXV compatibility for retrofit projects. It takes the complexity out of refrigerant transitions.

4. Product Finder
This is one of Ref Tools' most powerful additions. Product Finder gives you on-demand access to Danfoss product specifications, technical dimensions, installation guides, catalogs, brochures, and product images. You can also view compatible spare parts and accessories, build a product list, and export or share it directly with colleagues, purchasing teams, or suppliers. No more hunting through PDFs or waiting until you're back at the office.

5. Spare Parts
Access and order from an extensive catalog of Danfoss spare parts and service kits for industrial refrigeration — directly from the job site. Which brings us to the part you really need to know.

Keep Supply is Your Distributor Inside Ref Tools

When you order through the Ref Tools app, Keep Supply is the default distributor fulfilling your order. That means you get genuine Danfoss parts with the same fast, reliable service you already expect from us — without leaving the app, without switching tabs, and without extra steps.

It's a seamless connection between Danfoss's field tools and the supply chain you already trust.
