New design concept for greater performance, energy efficiency and redundancy
Breaking new ground: When it comes to large and hyperscale data centers, conventional air conditioning systems are up against their limits. Restricted space, electricity consumption and high heat loads are some of the challenges that need to be overcome. STULZ offers solutions to these challenges and guarantees efficient, demand-based and reliable air conditioning of your mission-critical equipment.
Our air handling units unique design allows space for taller server racks with greater IT load densities, therefore enabling air conditioning of the maximum heat load.
