New generation of A/C service units

Fully connected, with remote-control capability via an app

The A/C service units in the ArticPRO® line have been redesigned and optimized. The result: more functionality, improved handling, tried-and-tested quality, and an emphasis on “connectivity” and “digitization” in line with the Workshop 4.0 concept. This is a new generation of units with a new look and feel—as well as a new name. Here you’ll find a complete overview of all the latest developments.

Familiar units get a facelift

The new ArcticPRO® generation

New features

These are still the same ArcticPRO® units you’re familiar with—only better, more innovative, and more modern. The units are cutting-edge when it comes to connectivity and ease of maintenance—with Bluetooth and Wi-Fi, a large touch screen, a status monitoring app, and Remote Service.

New design

But the features aren’t the only things that have changed. So has the design. For example, you can now flip the cover open like the hood of a car—no screwdriver required—to get at the inner workings of the unit. And it’s not just the design that’s new—the unit names are too.

New names

Be aware: Even the names of the A/C units have changed.
In the following we'll tell you which unit is behind the new name.

Here’s an overview of the new unit names:

ACX 120 is now ACX 320 ACX 220 is now ACX 420*
ACX 150 is now ACX 350* ACX 250 is now ACX 450*
ACX 180 is now ACX 380*
