Triton Thermal has published a comprehensive guide for colocation operators navigating the converging pressures of refrigerant phasedowns, rising energy costs, and AI workloads that demand ten times the rack density legacy CRAC systems can deliver.
-- HOUSTON, TX — Colocation operators across the United States are facing a narrowing window to replace aging CRAC cooling equipment, as refrigerant regulations, energy costs, and a generational shift in compute density collide on the same timeline.
Triton Thermal, a Houston-based data center liquid cooling design and installation firm, has released a detailed CRAC unit replacement guide that walks facility operators through when to act, what their options are, and what happens if they wait.
The guide arrives as the data center industry grapples with two simultaneous infrastructure challenges. On the regulatory side, R-22 refrigerant production ended in 2020, and R-410A — the refrigerant in most CRAC units installed over the past fifteen years — faces a seventy percent supply reduction by 2029 under the AIM Act. Replacement refrigerants like R-454B are not drop-in retrofits. Full replacement is the only option.
On the compute side, GPU-intensive AI workloads are driving rack power demands that air cooling simply cannot meet. NVIDIA's H100 generation requires approximately forty kilowatts per rack. The GB200 NVL72 requires over one hundred twenty kilowatts and mandates liquid cooling by design. The overwhelming majority of colocation facilities were built to support three to eight kilowatts per rack. That gap is not closeable with better CRAC units.
"The operators we talk to are often surprised by how close the 2029 refrigerant cliff actually is," said Mike Donovan, Principal and Co-Founder of Triton Thermal. "When you factor in equipment lead times and the capital planning cycle for a facility upgrade, waiting another year or two to start that conversation is a real risk."
The financial case for action is well-documented. A one-megawatt facility running at a PUE of one point seven versus one point three wastes roughly three hundred fifty thousand dollars per year in energy costs at standard utility rates. Real-world replacement projects show payback periods between one point nine and three point eight years, with annual savings ranging from one hundred forty-four thousand dollars to over five million dollars depending on facility scale.
Downtime risk adds additional urgency. Data center outages now cost an average of fourteen thousand dollars per minute, and cooling-related failures account for thirteen to nineteen percent of all outages. Equipment past its design life and running on refrigerant with no supply security represents a compounding liability.
The guide outlines three upgrade paths: like-for-like CRAC replacement for refrigerant compliance; conversion to centralized chilled water with CRAH air handlers for meaningful PUE improvement; and transition to hybrid or full liquid cooling for facilities competing for AI and HPC tenants.
The Triton Thermal team works with operators across all three paths as a vendor-neutral integrator, drawing on partnerships with leading manufacturers including Motivair, Green Revolution Cooling, Stulz, and Epsilon.
