The US is home to most of the companies that built this market. Below is our 2026 list of the leading vendors, with their headquarters, technology and the deployments each one suits best.
How we ranked them
Every company on this list is headquartered in the US and sells immersion cooling for servers as a core product. We weighed four things:
• US presence: headquarters, manufacturing or operations in the United States
• Focus: server immersion cooling as a main product line, not a side offering
• Track record: production deployments and named customers
• Breadth: tanks or racks, CDUs, fluids, monitoring and field support from one vendor
The list at a glance
- GRC (Green Revolution Cooling) – Austin, TX: single-phase rack immersion pioneer
- LiquidStack (Trane Technologies) – Carrollton, TX: single- and two-phase immersion
- Midas Immersion Cooling – Austin, TX: single-phase XCI tanks
- Vertiv – Westerville, OH: CoolCenter Immersion systems
- LiquidCool Solutions – Rochester, MN: sealed chassis-level immersion
- Engineered Fluids – Tyler, TX: dielectric coolants and SLICTanks
- TMGcore – Plano, TX: two-phase OTTO platform
GRC (Green Revolution Cooling)
Headquarters: Austin, Texas · Founded: 2009 · Best for: AI, HPC, edge and hyperscale operators who want a proven single-phase system from one vendor
GRC pioneered single-phase immersion cooling in 2009 and is still the most established US specialist. It holds 30 patents, runs an ISO 9001:2015 quality system and has deployments in 24 countries. Its systems are vetted by Dell, Intel and Vertiv and used by the US Air Force, Intel, Shell and research centers such as the Vienna Scientific Cluster.
GRC systems cut cooling energy by up to 90% and server power by about 11% by removing fans. They work with servers from Dell, HPE, Supermicro, NVIDIA, Intel and other leading OEMs, including NVIDIA H100-class GPU nodes for AI and machine learning. Greenfield builds can skip chillers, CRACs and raised floors, which lowers upfront cost by up to 30%.

LiquidStack (Trane Technologies)
Headquarters: Carrollton, Texas · Founded: 2012 · Best for: teams weighing single- vs two-phase immersion alongside direct-to-chip
LiquidStack sells single-phase and two-phase immersion systems, direct-to-chip CDUs and prefabricated modular data centers. In 2024 it moved its global headquarters and manufacturing from the Boston area to a 20,000+ sq ft site in Carrollton. Trane Technologies completed its acquisition of LiquidStack on March 3, 2026, and now sells it through its commercial HVAC Americas business.
Midas Immersion Cooling
Headquarters: Austin, Texas · Founded: 2010–2011 · Best for: enterprise AI and HPC buyers who want standalone single-phase tanks
Midas began as one of the first commercial immersion-cooled data centers before turning to tanks full time. The company reports about half a gigawatt of immersion heat rejection deployed, roughly 4,000 tanks, by 2024. Its patented XCI tanks use a redundant architecture and can be configured for 200 kW+. In 2024 Midas dropped crypto-miner cooling to focus on enterprise AI and HPC.
Vertiv
Headquarters: Westerville, Ohio · Listed: NYSE: VRT · Best for: operators who want immersion from a large critical-infrastructure vendor
Vertiv launched its CoolCenter Immersion system for AI and HPC in late 2025. Each system handles 25 kW to 240 kW, in self-contained or multi-tank setups, with a tank, CDU, variable-speed pumps and BMS connectivity built in. It was released first in Europe, the Middle East and Africa, so US buyers should confirm availability.
LiquidCool Solutions
Headquarters: Rochester, Minnesota · Founded: mid-2000s · Best for: edge and rugged sites that need immersion in standard racks
LiquidCool takes a different route: instead of open tanks, it seals each server in a fluid-filled chassis. Directed flow inside the chassis targets the hottest CPUs and GPUs. Because the chassis fit standard vertical racks, sites need no structural changes. The company holds more than 60 patents.
Engineered Fluids
Headquarters: Tyler, Texas · Founded: 2017 · Best for: integrators who need US-made dielectric coolants and pre-engineered tanks
Engineered Fluids makes single-phase dielectric coolants, including ElectroCool, AmpCool and BitCool, at its plant in Tyler. It also sells SLICTank tank systems, pumps and dry coolers, with sales and R&D in St. Petersburg, Florida. The company is ISO 9001 certified and reported 2024 revenue above $25 million.
TMGcore
Headquarters: Plano, Texas · Best for: specialist two-phase builds where floor space is the main constraint
TMGcore builds OTTO, a two-phase immersion platform with power, network and cooling integrated in one unit. It is designed for extreme density, about 1.2 MW of compute in roughly 320 sq ft. TMGcore has worked with Dell on immersion-ready servers. It is a small team today, so check capacity and support coverage before you commit.
How to choose an immersion cooling partner
- Match the technology. Single-phase fluids don't boil off and are simpler to handle. Two-phase adds density at a higher fluid cost.
- Check server support. Confirm your OEM servers are validated for immersion and that warranties carry over.
- Look at the whole stack. Tanks, CDUs, fluid supply, monitoring and field service should come from one accountable vendor.
- Ask for measured results. Request PUE, energy and uptime data from real deployments, not lab claims.
- Model the TCO. Compare CapEx and OpEx against air or direct-to-chip for your own load. The GRC TCO calculator does this in minutes.
