The new version of the

Danfoss TurboTool® 2.0

app for all your full service

Danfoss Turbocor® compressor needs.

Download the

2.0 app today!

TurboTool® helps you to

quickly identify the required

spare parts. A quick scan of

the compressor serial # using

your smartphone camera or by

entering the part # or model

#, and the app will display

potential spare parts kits.

The TurboTool® app makes

it easy for technicians to

troubleshoot issues on Danfoss

Turbocor® compressors.

The user can select from a list

of symptoms in the app that

match the problems exhibited

by the compressor being

serviced. The app will then

list potential causes, solutions

to the problem, and service

literature to reference for further

information.

The app provides the correct

operating parameters for key

components: no need to keep

reference documents on hand.

You no longer need to keep

hundreds of pages of parts

catalogs and training manuals.

With the app, all of this

information is at your fingertips

on your smart device.

With the app, you can access

videos made by Danfoss

Turbocor® that demonstrate

how to remove, install, and

rebuild key components on

Danfoss Turbocor® compressors.
