Customized solutions

From a necessity to development and manufacturing

Customized Precision AHU

The STULZ group is synonymous with high flexibility and adaptability to the specific requirements of each project.

The Customized AHU preserves the watertightness, low thermal transmission and mechanical resistance features of our construction, but it specializes in applications that require a high demand for cooling power and large air flows without compromising the energy efficiency that is so important in systems in high-temperature environments. precision.

These units are perfectly adapted to mission-critical applications such as data centers and IT infrastructures, even industrial, where the control of temperature and humidity is more precise, covering air flow ranges up to 180,000 m3 / h and 600 kW of cooling power. , being able to develop higher yields under study.

As a leading manufacturer of precision air conditioning, we apply our expertise in this type of solution, with our own development unit control management, adaptable to the specific requirements of the installation.
