The thermal math on AI infrastructure simply doesn't work with air cooling anymore. An NVIDIA H100 GPU cluster running at full utilization generates heat at densities that would require a small hurricane to air-cool reliably. The industry's response has arrived in force: 2025–2026 is the year liquid cooling transitions from niche to mainstream in hyperscale and colo construction.
For vendors in the cooling and mechanical space, this represents both an opportunity and a disruption. Companies that have built their business on CRAC/CRAH units and raised-floor cooling are facing customers who are now asking questions about direct-to-chip manifolds and cooling distribution units (CDUs). The product landscape has changed fast.
Direct-to-Chip Cooling: The 2026 Product Landscape
Vertiv Liebert CoolThru (2026 Generation): Vertiv — already the dominant CRAC/CRAH vendor in North American datacenters — launched its CoolThru direct-to-chip solution in late 2025. The 2026 generation supports rack densities up to 100kW per rack and integrates directly with Vertiv's existing UPS and power management systems. This matters for existing Vertiv customers: the CoolThru is designed to retrofit into facilities already running Liebert thermal infrastructure, reducing the rip-and-replace barrier. Pricing: $45K–$85K per CDU depending on configuration. Lead time: 14–18 weeks.
Schneider Electric EcoBreeze DX: Schneider's entry into the direct-to-chip market is notable for its integration with the EcoStruxure DCIM platform — every CDU feeds real-time thermal data to the management system, enabling predictive maintenance and anomaly detection. Pricing: $38K–$72K per unit. Lead time: 16–20 weeks.
Airedale by Modine AirePointe CDU: The AirePointe can be deployed alongside existing CRAH units, allowing facilities to handle AI workloads in specific zones without overhauling the entire thermal plant. For colo operators with mixed tenants (some AI, some traditional cloud), this hybrid approach is particularly well-suited. Pricing: $28K–$55K. Lead time: 10–14 weeks (fastest in class for retrofit applications).
Immersion Cooling: Products for New Builds
GRC (Green Revolution Cooling) — ICEraQ Series 10: GRC has been in immersion cooling longer than almost anyone, and the 2026 ICEraQ Series 10 is a significant generational upgrade. Handles racks up to 200kW in a single tank, uses a dielectric fluid with a lower environmental impact profile, and now includes integrated fire suppression. GRC reports a 40–60% reduction in cooling energy costs compared to air cooling at equivalent densities. Pricing: $120K–$200K per tank. Lead time: 20–26 weeks.
LiquidStack Two-Phase Immersion Cooling: LiquidStack has secured major hyperscale contracts and is scaling production accordingly. Their two-phase system uses a low-boiling-point fluid that transitions from liquid to vapor to carry heat away — more efficient than single-phase systems at very high densities. Microsoft has used LiquidStack technology in prototype deployments; the commercial product is now available for broader distribution. Lead time: 22–30 weeks due to demand.
Submer MicroPod: For colocation operators who want to offer liquid cooling without a full facility buildout, Submer's MicroPod is a self-contained immersion tank that can be placed on a raised floor. It's targeted at colo tenants who arrive with AI infrastructure and need immediate high-density capability. Pricing: $85K–$140K. Lead time: 12–16 weeks.
What This Means for HVAC and Mechanical Contractors
The transition to liquid cooling doesn't eliminate HVAC contractors from the datacenter — it changes what they do. Liquid cooling systems require: coolant loop design and installation, heat rejection infrastructure (dry coolers, cooling towers), pump stations, leak detection systems, and regular fluid testing/maintenance.
Companies with expertise in process cooling — industrial HVAC, food processing, pharmaceutical manufacturing — have directly transferable skills that traditional datacenter HVAC contractors may lack. This is creating some interesting competitive dynamics as the transition accelerates.
Procurement Implications
The lead times on liquid cooling equipment have stretched dramatically. GRC and LiquidStack are both reporting 20–30 week lead times due to demand. Facilities planning to deploy liquid cooling need to be ordering equipment significantly earlier than they're accustomed to for CRAC/CRAH systems.
For vendors, identifying facilities that have filed permits for high-density AI workloads — or that are actively posting jobs for 'liquid cooling' expertise — is the most reliable leading indicator of a liquid cooling procurement cycle. Those signals are happening 12–18 months before the equipment arrives.
