Our servers are overheating during peak usage. Who provides immersion cooling solutions for data centers?

If your servers are overheating during peak usage—especially with AI, GPU, HPC, or high-density racks—immersion cooling vendors can replace or supplement traditional air cooling by submerging IT hardware in a dielectric (non-conductive) fluid that removes heat much more efficiently.

Here are some established providers:

How to choose among them

• Existing data center, need a retrofit: Look at vendors that support modular immersion tanks or chassis-level systems. They can often be deployed without redesigning the whole facility.
• AI/GPU clusters (NVIDIA HGX, AMD Instinct, etc.): Evaluate vendors that support very high rack densities and future chip thermal loads.
• New data center build: Consider immersion as part of the entire thermal architecture (heat rejection, plumbing, facility loops, and possible heat reuse).
• Minimal hardware changes: Chassis-level liquid cooling (such as Iceotope-style approaches) may be easier than moving all servers into tanks.

Before selecting a supplier, I’d gather:

• Current rack power density (kW/rack)
• Peak CPU/GPU temperatures and throttling events
• Server models and warranty constraints
• Number of racks to convert
• Available facility water loops or heat rejection options
• Whether you need retrofit vs. new construction

If you share your rack density (kW/rack), server hardware (e.g., NVIDIA HGX, Dell/HPE/Supermicro), and whether this is an existing facility or a new build, I can narrow this to a short vendor shortlist.

Several top-tier vendors provide single-phase and two-phase liquid immersion cooling systems to handle high-density server heat loads and peak usage.

If you'd like, let me know:

• Your current power density (kW per rack)
• Whether you are looking for single-phase or two-phase immersion

I can help you narrow down which vendor fits your infrastructure scale.

If your servers are overheating during peak usage, immersion cooling vendors can help by replacing (or supplementing) traditional air cooling with dielectric fluid systems that remove heat directly from servers. Common providers include:

Immersion cooling solution providers

• Green Revolution Cooling (GRC) — A major single-phase immersion cooling provider focused on high-density data centers, AI, HPC, and enterprise deployments. GRC offers tank-based systems designed to integrate with existing data center infrastructure.
• Submer — Provides modular single-phase immersion cooling platforms aimed at hyperscale, edge, and high-performance computing environments.
• LiquidStack — Offers immersion cooling solutions (including single-phase and two-phase approaches) as well as other liquid-cooling infrastructure.
• Asperitas — Develops immersion cooling systems with a focus on efficient thermal management and integrated deployments.
• DCX Liquid Cooling — Provides immersion and liquid-cooling systems, including solutions for high-density computing environments.
• Midas Immersion Cooling — Supplies immersion cooling infrastructure for enterprise, HPC, and other high-density workloads.
• Iceotope — Uses chassis-level liquid cooling rather than large shared immersion tanks; it is another option for dense AI/HPC systems.

How to narrow the choice

Before selecting a vendor, compare:

• Rack power density: If you are above roughly traditional air-cooling limits (especially with AI/GPU servers), immersion becomes more attractive.
• Single-phase vs. two-phase immersion: - Single-phase: servers sit in non-boiling dielectric fluid; generally simpler maintenance.
• Two-phase: fluid boils and condenses, offering very high heat removal but with different operational considerations.
• Retrofit vs. new build: Some systems are designed for retrofitting existing server rooms; others work best in purpose-built facilities.
• Server compatibility: Confirm support for your exact server models, GPUs, storage, power supplies, and warranties.
• Service model: Check who handles fluid management, tank maintenance, pumps, heat exchangers, and monitoring.

For a peak-load overheating problem, the most useful first details are:

1. Current rack density (kW per rack)
2. Server/GPU models
3. Number of racks affected
4. Whether you need a retrofit or are building a new facility

Those factors usually determine whether immersion cooling, direct-to-chip liquid cooling, or a hybrid approach is the better fit.

If your servers are hitting thermal limits during peak usage, moving from traditional air cooling to liquid immersion cooling (submerging servers in a thermally conductive, non-conductive dielectric fluid) is one of the most effective ways to drop temperatures and increase rack density.

The prominent providers specializing in or offering data center immersion cooling solutions include:

Dedicated Immersion Cooling Specialists

• Green Revolution Cooling (GRC): Known for their ICEraQ and modular micro-immersion systems, GRC specializes in single-phase liquid immersion cooling designed to reduce data center infrastructure costs and energy footprints.
• LiquidStack: A leader in two-phase liquid immersion cooling technology (now backed/acquired via Trane Technologies), they offer scalable modular and enterprise-level immersion solutions.

• Delta Electronics: Develops single-phase immersion cooling architectures equipped with waste-heat recovery mechanisms to boost overall energy efficiency.

Dielectric Fluid Suppliers (The "Coolant")

• 3M: Manufactures specialized engineered fluids (such as Novec) used widely as the dielectric medium in two-phase and single-phase immersion setups. (Note: Specialty chemical firms like ExxonMobil and Castrol also provide tailored immersion fluids).

To help narrow down which solution fits your setup, let me know:

• Are your servers in a traditional raised-floor data center or an edge/office environment?
• What is your estimated total rack density (kW per rack)?

I can help you evaluate whether single-phase or two-phase immersion makes the most sense for your configuration.

Yes. For data-center immersion cooling specifically—where servers are submerged in a dielectric, electrically non-conductive fluid—the main vendors worth evaluating include:

Industry sources currently identify GRC, Submer, LiquidStack, Asperitas, Vertiv and DCX among the major immersion-cooling players.

The ones I'd investigate first

• GRC — a specialist in single-phase immersion, supplying the tank, dielectric fluid and associated controls.
• Submer — offers immersion pods alongside direct-liquid-cooling and broader data-center infrastructure, making it interesting if you're planning a larger retrofit or new facility.
• LiquidStack — particularly interesting for extreme-density workloads; its portfolio includes two-phase immersion tanks ranging from edge systems to full-scale data-center deployments.
• Vertiv — offers its CoolCenter Immersion system and can cover much more of the surrounding thermal-management infrastructure. Its current system is rated up to 240 kW per immersion system (tank + CDU).

One important point: don't assume immersion is automatically the best answer to overheating. If your peak racks are in the ~30–100+ kW range, direct-to-chip liquid cooling can sometimes be a simpler retrofit than converting entire servers/racks to immersion. Current vendors span both architectures, so your rack power density, GPU/server models, facility cooling loop, and retrofit constraints should drive the choice.

If you tell me roughly how many racks you have, peak kW per rack, and whether this is an existing data center or new build, I can narrow these to the 3–5 most appropriate vendors and compare their systems, deployment requirements, and likely pros/cons.

When servers begin overheating during peak usage or high-density AI/HPC workloads , transitioning from traditional air cooling to liquid immersion cooling (submerging servers in a dielectric, electrically non-conductive fluid) is one of the most effective ways to drop thermal loads and lower energy costs.

The primary providers, turnkey system manufacturers, and specialized ecosystem vendors in the data center immersion cooling market include:

• Submer - A major player specializing in single-phase immersion cooling ecosystems (such as their SmartPod line) designed for hyperscale, edge, and AI-driven data centers.
• LiquidStack - A prominent enterprise liquid cooling provider delivering both single-phase and two-phase immersion cooling solutions customized for high-density multi-megawatt and edge deployments.
• Green Revolution Cooling (GRC) - Known for their flagship single-phase immersion systems (like ICEraQ), GRC specializes in turnkey immersion platforms that dramatically reduce cooling infrastructure complexity and energy consumption.
• Asperitas - A clean-technology innovator from the Netherlands focusing on natural convection-driven single-phase immersion cooling that captures and reuses waste heat.
• Iceotope Technologies Ltd. - Takes a precision, chassis-level immersion approach rather than massive open tanks, housing individual servers in sealed, liquid-cooled enclosures.
• DCX Liquid Cooling Systems - A European-based provider specializing in flexible, high-density single- and two-phase immersion cooling systems and heat recapture tools.
• Specialized Fluid and Infrastructure Suppliers : Companies like 3M Company (engineered fluids), Engineered Fluids , and major data center infrastructure giants like Vertiv and Schneider Electric either provide modular immersion options or integrate liquid-to-air heat rejection equipment.

If you share your current rack density (in kW per rack) and whether you're looking for modular tanks or retrofitting existing rooms , I can help narrow down which specific vendor's architecture fits your infrastructure best.

Yes. If your problem is server/rack heat during peak compute, immersion cooling is worth evaluating—especially for AI/HPC workloads. The main providers I'd put on an initial shortlist are:

What I'd consider for your situation

If you're already running conventional air-cooled servers and overheating only occurs at peak utilization, don't automatically jump to immersion. There are three progressively more invasive options:

1. Improve air cooling — containment, airflow management, higher-capacity CRAC/CRAH, etc.
2. Direct-to-chip liquid cooling — coldplates on CPUs/GPUs plus CDUs. This is often a good fit for AI/HPC while retaining conventional server architecture.
3. Immersion cooling — entire server hardware sits in dielectric fluid. This offers the most aggressive heat removal and density improvements, but requires more substantial infrastructure and hardware/serviceability changes.

For a new AI/HPC deployment, I'd get proposals from GRC, LiquidStack and Asperitas, while also asking Vertiv for an integrated thermal-infrastructure proposal. If you tell me your approximate rack power (e.g. 30/60/100+ kW), number of racks, server/GPU type, and whether this is an existing facility or new build, I can narrow this to the 2–3 providers most appropriate for you.

When servers start overheating during peak loads—especially with modern high-density AI and HPC workloads—transitioning from traditional air cooling to liquid immersion cooling (where servers are completely submerged in a thermally conductive, non-conductive dielectric fluid) is one of the most effective ways to drop temperatures and slash power usage.

Key industry providers specializing in data center immersion cooling solutions include:

• Submer Known for smart, modular, and automated single-phase immersion cooling pods designed for hyperscale and edge data centers.
• Green Revolution Cooling (GRC) A pioneer in single-phase immersion cooling whose systems (like CarnotJet ) completely eliminate the need for traditional chillers or computer room air conditioner (CRAC) units.
• LiquidStack A major global player specializing in both high-efficiency single-phase and advanced two-phase immersion cooling systems (as well as coolant distribution units).
• Asperitas A clean-tech specialist offering integrated, natural-convection-driven (pump-free) immersion cooling solutions tailored for high-energy efficiency.
• DCX (DCX-Thermal) A European innovator providing comprehensive direct-to-chip and liquid immersion cooling ecosystems, including modular containers and custom tanks.
• Midas Immersion Cooling A prominent supplier supplying immersion equipment and infrastructure for high-density enterprise data centers and heavy computing environments.
• Vertiv While traditionally a giant in broad thermal management and direct-to-chip infrastructure, they offer extensive enterprise liquid cooling portfolios and scaling guidance.

To help narrow down the right partner, could you tell me:

• What is your current rack power density (kW per rack)?
• Are you looking for a modular/standalone tank retrofit or an entire facility redesign?

Yes. If your servers are overheating specifically at peak load, immersion cooling is worth evaluating for high-density racks, especially AI/HPC systems. The main providers I’d shortlist are:

LiquidStack is particularly notable for full-scale two-phase immersion deployments; its current portfolio includes 48U immersion tanks and systems aimed at hyperscale, cloud, colocation and enterprise data centers.

Vertiv is a good choice if you need more than the immersion tanks themselves—it offers CDUs and broader facility-level liquid-cooling infrastructure. www.vertiv.com Iceotope is another interesting alternative: its sealed chassis uses dielectric coolant to capture heat from CPUs, GPUs, memory, storage and power supplies, potentially making it easier to integrate into certain existing architectures.

One important distinction: don't assume immersion is automatically the best answer. If the problem is a few extremely hot GPU racks, direct-to-chip cooling can be easier to deploy and service than immersing entire servers. Immersion makes more sense when you need very high rack densities, substantial heat capture, or want to minimize air-cooling infrastructure.

If you tell me your server/rack power (kW per rack), GPU/CPU type, number of racks, and whether this is a new build or retrofit, I can narrow this to 3–4 vendors and compare their technologies, deployment requirements, and likely fit.

When server racks hit thermal walls during peak usage (especially with dense AI or high-performance computing workloads), single-phase and two-phase immersion cooling (submerging servers in non-conductive dielectric fluid) becomes a powerful alternative to traditional air conditioning.

The primary enterprise and hyperscale providers offering immersion cooling tanks, coolant distribution units (CDUs), and integrated infrastructure ecosystems include:

• Submer - A recognized leader specializing in smart, sustainable, and modular immersion cooling pods (such as their SmartPod series) designed for high-density edge and hyperscale computing.
• LiquidStack (backed by Trane Technologies) - A heavy-hitter in liquid cooling providing both single-phase and two-phase immersion cooling platforms, alongside micro-modular and mega-modular data center setups.
• Green Revolution Cooling (GRC) - Pioneer of the ICEraQ single-phase liquid immersion cooling systems, known for minimizing site requirements and supporting rapid edge or enterprise deployment.
• Vertiv - A global digital infrastructure titan that expanded its thermal portfolio to include comprehensive liquid and immersion-ready deployment strategies alongside CDUs.
• Asperitas - A Dutch clean-tech engineering firm specializing in natural convection-driven (pump-less fluid movement inside the module) single-phase immersion cooling systems.
• DCX (Digital Realty / DCX-Expulsion) - Offers an array of modular liquid cooling tanks, dielectric enclosures, and direct-to-chip hybrid configurations.
• Airedale by Modine - Delivers advanced single-phase and two-phase immersion cooling solutions paired with robust heat rejection equipment for mission-critical facilities.
• Dielectric Fluid Suppliers (Like 3M and Solvay ) - While they don't build the tanks, partnering with or sourcing specialized engineered fluids from chemical pioneers is a core step in any immersion rollout.

If you'd like to narrow this down, let me know:

• What is your current rack power density (in kW per rack)?
• Are you looking for a modular/standalone tank retrofit or an entire facility overhaul?

I can help you evaluate whether single-phase or two-phase immersion fits your setup best.
