What makes a Gradian Fan Cooling Wall?
Vertical Stacking Architecture
Increase cooling capacity without consuming additional floor space. Optimized vertical stacking supports greater airflow, enabling higher-density data center deployments.
High Efficiency ECM Fan Arrays
Deliver precise airflow with lower energy consumption, helping reduce operating costs while maintaining reliable cooling for mission-critical data center environments.
Flexible Options for Mission-Critical Environments
Optional humidification, electric heat, and Automatic Transfer Switch (ATS) capabilities maintain precise environmental control and operational continuity across a wide range of facility conditions.

Built For What’s Next
AI and HPC workloads run hotter than most facilities were built for. Handle the density they throw off without needing to overbuild.
Up to 900 kW Per Unit - Handle the dense thermal loads modern AI training and inference racks generate.
110,000 CFM Airflow - Move the volume of air high-density compute actually needs.
AI & HPC-Ready Platform - Built for where compute demand is headed, not just where it is today.
Out of the Box Control
Stay connected and in control. Get the precision needed for mission-critical operations, ready from day one.
Factory-Integrated Controls - Skip the integration guesswork with a controls platform that's ready to run from install day.
Precise Cooling Management - Monitor and adjust critical cooling functions with the visibility mission-critical operations demand.
BMS-Ready Communication - Connect into your existing building and data center management systems without a custom integration project.
Deploy Faster, Disrupt Less
Scaling infrastructure shouldn't mean tearing out what's already running. Add capacity quickly and efficiently, without a major redesign standing between you and going live.
Modular Stacking - Add capacity in stages as your infrastructure grows, without ripping out and redesigning what's already running.
Faster Installation - Streamlined assembly helps shorten deployment timelines and get critical cooling operational sooner.
Built for Expansion - Scale on your timeline, whether that's a phased rollout or a rapid capacity add.
Questions, answered.
The STK fan coil wall is designed for data centers, AI computing environments, hyperscale facilities, colocation sites, and other mission-critical applications that require scalable, high-capacity cooling and reliable airflow management.
