Eva Caño: C&R 2025 will allow STULZ to show its technological leadership

What are the challenges facing the air conditioning sector?

The air conditioning sector is going through a time of great complexity, driven by challenges affecting both manufacturers and end-users. Firstly, regulatory pressure and the energy transition call for the design of solutions that reduce consumption and emissions, incorporate low GWP refrigerants and allow us to work with higher water temperatures to maximise the use of free cooling and the integration of more efficient systems.

Secondly, growing demand in critical environments - from high-density data centres to hospitals, laboratories and sensitive industrial processes - requires increasingly reliable systems with built-in redundancy to maintain operations even under extreme conditions.

Digitalisation is another key issue. Customers expect equipment that can be integrated into different protocols, with advanced control, continuous monitoring and predictive maintenance, to reduce downtime and optimise property costs. Space constraints and the need for modularity call for scalable, easy-to-install equipment that can be adapted to the evolution of installations without compromising continuity of service.

Sustainability is also a key priority. We actively work to incorporate low GWP refrigerants, such as R454C, and to develop solutions that reduce our customers' carbon footprint throughout the life cycle of the equipment.

STULZ is committed to leading this evolution, combining technological innovation, quality and a strong focus on sustainability, a message that we will reinforce at C&R 2025. 

What does STULZ contribute to society and its customers?

For more than 75 years, STULZ has been developing precision cooling solutions that ensure the reliability and efficiency of critical infrastructures around the world. Our contribution to society and our clients is threefold. Firstly, operational continuity: we ensure that sensitive environments such as data centres, hospital facilities or industrial processes operate without interruption thanks to stable and redundant climate control.

Secondly, we provide energy efficiency and sustainability. We develop equipment capable of reducing electricity consumption and optimising the use of natural resources, contributing directly to the reduction of the carbon footprint. And thirdly, we offer applied technological innovation. We combine German engineering with an in -depth knowledge of the domestic market to offer solutions adapted to every need, always aligned with the current trends in the sector: high thermal load density, digital integration and increasingly demanding hygienic requirements.

What are the company's main products, services?

Our portfolio is structured around two segments based on the type of application. On the one hand, we offer a wide range of solutions for precision air conditioning for mission-critical environments and data centres, ensuring maximum reliability and efficiency in continuous operation. We also have a specific line industrial applications and hygienic-sanitary environments, where air processing units are essential to ensure optimum indoor air quality and meet the highest hygienic standards.

We have a strategic focus on three key markets. Firstly, data centres and mission critical environments, providing precision cooling systems (from CRAC/CRAH, In-rows, Fan Walls, UTAs, to the latest technology in liquid cooling solutions) that ensure operational continuity 365 days a year and energy efficiency in these environments.

Secondly, industrial, commercial and institutional applications, where we offer high-efficiency air conditioning solutions for sensitive manufacturing processes, ensuring the thermal stability required for production. We also develop systems that enable the design of healthy buildings, in which the thermal comfort and well-being of the occupants are a priority, ensuring adequate ventilation, optimum indoor air quality and maximum energy efficiency of the installations.

And the third market is hygienic-sanitary applications, with equipment designed specifically for hospitals, laboratories and environments that require certified hygienic conditions, incorporating materials, finishings and configurations that comply with demanding health and safety standards.

And not forgetting our consulting, engineering and maintenance services, allowing us to accompany our clients through all phases of their project: from initial design to continuous operation, ensuring maximum availability and efficiency throughout the life of the system.

What particular new offerings and solutions will STULZ bring to C&R 2025?

The C&R fair is an unmissable event for professionals and the most important high-level technical meeting point for the sector in Spain. For STULZ in particular, it represents a key opportunity to showcase our technological leadership, to strengthen our proximity to customers and partners, and to be part of the evolution of the HVAC industry.

At this edition, at our stand in Hall 9, we will be presenting two major innovations. On the one hand, "ClimaPac Plus": the evolution of our well-known range of "ClimaPac" air processing units, new box model, now with specific hygienic finishes for hospital and pharmaceutical applications. It is our response to a market that increasingly demands reliable, sustainable solutions adapted to the most demanding hygiene environments.

Then there is our "CyberWall CWV," an innovative Fan Wall type system with vertical configuration, designed for high thermal density data centres. With no false floor required, it offers air returns >40°C, optimising flow using CFD to reduce energy consumption and achieve low pPUE, and incorporate autonomous control and group operation to manage room air conditioning as a complete system. Its modular design, with upper airflow return and front discharge with direct drive to the data centre, is designed to facilitate maintenance and direct access during commissioning, operation, and servicing, as the return duct isolates the machine room from the extracted heat.
