Watch the video to hear from Katja Heller, our Quality and Supply Chain Manager, as she shares how her team in Wurzen has improved end-of-line testing for CAIRplus AHUs. Thanks to ISYteq 4.0 integration, every unit is now fully configured, tested, and ready for peak performance.

FläktGroup’s CAIRplus AHUs with ISYteq 4.0 – From Rigorous Testing to Rapid Installation

Our Quality and Supply Chain Manager, Katja Heller, explains alongside her team in Wurzen, Germany, the latest improvements to our end-of-line testing system for CAIRplus AHUs. Thanks to smart integration with ISYteq 4.0 controls, every unit is now reliably configured, thoroughly tested, and ready to deliver optimal performance the moment it’s installed.

From Design to Delivery: Confidence in Every Unit 

Developed through close collaboration between our controls experts and equipment partners, this innovative system transforms how we test CAIRplus AHUs equipped with ISYteq 4.0 controls.

Every unit leaves our facility,

  • Fully tested to meet rigorous quality standards
  • Reliably configured for seamless integration
  • Primed for high performance from the moment it’s installed

At FläktGroup, precision starts long before an AHU reaches the installation site.

Through intelligent integration with our LPlus Selection Tool, every CAIRplus unit with ISYteq 4.0 controls is configured and tested to match its exact specification.

From dynamic, order-specific testing to full traceability and documentation, our end-of-line process ensures each unit is reliable, compliant, and ready to perform from day one.

Let’s dive into the details below. 

Intelligent Integration with Selection Tools

The system connects directly to FläktGroup’s LPlus Selection Tool, automatically receiving a data package tailored to each order. This includes:

  • Specific software configuration for the ISYteq 4.0 control system
  • A detailed test plan aligned with the selected components and functions 

This eliminates guesswork and shortcuts, ensuring every unit is tested precisely according to its unique specification. 
 
Rigorous, Reliable Testing

Each unit undergoes a dynamic, configuration-specific test that includes:

  • Functional performance checks against reference values
  • Verification of integration functions to catch faults or damage

Validation against harmonised standards and internal quality benchmarks 

Only units that meet all criteria proceed to final commissioning, ensuring smooth operation from installation onward.

Quality Assurance and Traceability

Every test generates a detailed protocol stored in FläktGroup’s database. This documentation:

  • Records all test results
  • Confirms compliance with internal quality standards
  • Supports full traceability for each unit

This process reflects FläktGroup’s commitment to smart engineering, reliable systems, and deep pride in delivering high-quality air handling solutions. 

The Bottom Line: Quality, Speed & Reliability

By implementing these testing standards we’re able to deliver benefits to customers.

Yes, That Means No Toolbox Required.

Thanks to ISYteq 4.0’s plug-and-play design and external quick-connect cabling, installing a CAIRplus AHU is so simple, you’ll only need one tool: a screwdriver. That’s right — no complex wiring, no crawling inside the unit, and no guesswork. Just connect, tighten, and move on. It’s almost suspiciously easy… but that’s what smart engineering is all about.
