Designed for precision. Specified with confidence.
The UltraLink Controller is a VAV damper delivering ultrasonic precision without the need for cleaning or recalibration. Designed for low-flow DCV systems, it ensures long-term accuracy and energy-efficient performance.
With the sensors placed outside the direct airflow path, UltraLink avoids dirt buildup and pressure loss, making it particularly reliable in extract air applications.
Key benefits:
-
Ultrasonic measurement – Airflow, velocity (0.2-15 m/s) and temperature (-10 to +50°C)
-
Sensor placed outside airstream – No obstruction meaning stable measurement accuracy over time
-
Maintenance-free – No cleaning of measuring cross or recalibration required
-
Unobstructed airflow – Lower pressure loss and reduced noise level
-
Fast commissioning – Bluetooth setup via OneLink mobile app
-
BIM-ready – Integrated with LindQST and CAD tools
Extract air is tough.
UltraLink makes it easy.
Traditional VAV dampers lose accuracy in dusty extract air. UltraLink’s ultrasonic sensors avoid this by being positioned outside the airflow — maintaining precision over time without the need for cleaning or recalibration.
It’s the VAV damper HVAC consultants trust for reliable extract air regulation in DCV systems.

Perform for years.
The UltraLink Controller is built for fast, flexible installation:
- Plug-and-play setup
- Rotatable sensors and damper housing for optimal positioning
- Bluetooth commissioning via OneLink mobile app
- Room-by-room setup and disturbance compensation
"What I really like about UltraLink is that I can configure everything from my phone – no need to climb ladders or access ceiling voids."

Precision that pays off
— and scales with your needs.
The UltraLink Controller supports comfort, energy-efficiency, and long-term reliability in buildings — with minimal maintenance and built-in upgrade path to room-level DCV.
For smaller buildings or retrofit projects without a full BMS, the Ultra BT solution offers a smart, scalable way to achieve better indoor climate control — without complex integration.
UltraLink Controller is the foundation of Lindab’s Ultra BT system: a flexible DCV upgrade that grows with your needs.
- Add up to five sensors per unit
- Monitor CO₂, humidity, temperature, and presence
- Adjust indoor climate via the OneSet mobile app
- Start small, scale as needed
Built for flexibility and performance.
