Test Center

Stringent tests of capabilities, systems and components performance

Great capacity Test Center, the highest capacity and accurate in Europe allows to test the most demanding technical specifications, with the possibility to test air flows up to 240.000 m3/h and a 800 kW IT load, assisted by sophisticated software of parameterization and monitoring.

Units can be tested and optimized, even during the design and development phase, taking into account different temperature conditions, possible security failures, and parameters to proof current and real performance capabilities, energy and water consumption.


High-performance engineering

Discover the wide range that STULZ Tecnivel adapts to your projects, providing the added value of experience and quality, as well as the high technology inherent in all its equipment.

Our main objective is the development of innovative and specialised solutions according to the needs of our customers and market trends, for this we have an R&D engineering department supported by a team of professionals from different areas who know the specific needs of the HVAC market.

We guarantee the quality and performance of the equipment supplied.

STULZ has developed FAT (Factory Acceptance Test) live streaming so that customers can witness the testing of their equipment, without the need to travel to our production facility.

This effective and secure tool has provided a solution to the current difficulties of security and travel, bringing significant cost and delivery time savings and offering total flexibility.
