Upsite Technologies Celebrates 25 Years of Airflow Management Innovation and Cooling Optimization Leadership8 min read
Milestone reflects two and a half decades of advancing data center cooling efficiency and applied thermal science.
ALBUQUERQUE, NM – February 18, 2026 – Upsite Technologies, the global leader in data center airflow management and cooling optimization solutions, this year celebrates its 25th anniversary. Since 2001, Upsite has helped data center operators improve cooling performance, reduce energy waste, and strengthen operational reliability through science based airflow management and disciplined cooling optimization.
Upsite’s journey began with the launch of the KoldLok® raised floor grommet, a targeted solution designed to reduce bypass airflow and improve conditioned air delivery. That innovation established a core principle that focused airflow improvements can unlock measurable gains in cooling efficiency.
Upsite later expanded its portfolio with HotLok® rack airflow management products and AisleLok® aisle containment solutions, enabling operators to address airflow at the rack and row levels and create the conditions necessary for room level cooling optimization.
“Our approach has always been iterative,” said Lars Strong, P.E., Senior Engineer at Upsite Technologies. “Airflow improvements can begin at the Raised Floor, Rack, or Row levels depending on the facility. What matters is that after making those improvements, operators return to the Room level to optimize the cooling infrastructure and align it with the new airflow conditions. That check in at the Room level is how operators fully realize the value of their investments at the other levels. It enables them to lower PUE, reduce operating costs, and increase usable capacity while maintaining reliability. For 25 years, Upsite has focused on helping operators apply that discipline in a measurable way.”
Upsite’s 4 R’s of Airflow Management methodology, Raised Floor, Rack, Row, Room, provides a practical framework for implementing improvements that optimize the delivery and use of conditioned air throughout a facility.
Throughout 2026, Upsite will commemorate its 25th anniversary by highlighting key milestones and engaging partners and customers across the global data center community.
