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

For servers overheating during peak usage—especially with dense CPU/GPU workloads like AI, HPC, or analytics—immersion cooling vendors can replace or supplement traditional air cooling by submerging servers in a non-conductive dielectric fluid. The fluid absorbs heat directly from components and transfers it to a heat rejection system.

Some established immersion cooling solution providers include:

• LiquidStack — Provides single-phase and two-phase immersion cooling systems, including its DataTank systems for edge through large-scale data center deployments. It also offers direct-to-chip liquid cooling solutions.
• Submer — Develops immersion cooling pods and liquid-cooled data center infrastructure aimed at high-density compute environments, including AI and hyperscale deployments.
• Green Revolution Cooling (GRC) — Specializes in single-phase immersion cooling systems and works with server and infrastructure partners to deploy immersion-cooled platforms.
• Asperitas — A Netherlands-based immersion cooling provider focused on passive immersion systems and high-density computing environments.
• DCX – The Liquid Cooling Company — Offers immersion cooling solutions and related liquid cooling infrastructure.
• Midas Immersion Cooling — Provides immersion cooling systems for data center and high-performance computing applications.

When evaluating vendors, check:

• Server compatibility: whether your exact server/GPU platforms are validated for immersion.
• Cooling type: - Single-phase immersion — simpler maintenance; fluid remains liquid.
• Two-phase immersion — uses boiling/condensation of fluid and can handle very high heat densities.
• Rack heat load capability: especially important for modern AI GPUs.
• Service model: whether the vendor supplies only tanks or also integration, fluids, pumps, heat exchangers, monitoring, and support.
• Retrofit feasibility: whether your current facility can support the electrical, mechanical, and heat-rejection changes.

If you share your approximate rack power density (kW/rack), server models/GPUs, data center size, and whether this is a retrofit or new build, I can help narrow the best-fit vendors.

When peak usage causes overheating, transitioning to single-phase or two-phase liquid immersion cooling (where servers are submerged in thermally conductive dielectric fluid) can dramatically increase thermal capacity and density. [1][2]

Which approach fits you?

If you're dealing with existing servers that spike in temperature during peak usage, I'd first determine whether you need:

The key issue isn't simply choosing a tank: server compatibility, dielectric fluid, rack power density, heat-rejection infrastructure, maintenance procedures, and whether your existing servers can be immersed all matter.

If you tell me roughly how many servers/racks you have, rack power (kW), CPU/GPU types, and whether this is an existing data center or new build, I can narrow this to the 3–5 most appropriate vendors and estimate what a retrofit might look like.

When servers start overheating during peak usage, transitioning from traditional air cooling to single-phase or two-phase liquid immersion cooling —where servers are fully submerged in thermally conductive, electrically insulating dielectric fluid—is one of the most effective ways to drop temperatures and dramatically increase rack density.

Several prominent enterprise-grade vendors specialize in turnkey tanks, coolant fluids, and integrated data center immersion infrastructure:

If you'd like to narrow down which vendor fits your setup, tell me:

• What is your current total IT load (kW) and rack density?
• Are you looking for a retrofitting solution for existing server racks or an all-new modular container/pod?
• Do you have a preference between single-phase (oil/synthetic fluid) or two-phase immersion?

Yes. If you're specifically looking for immersion cooling—where servers are submerged in a dielectric, electrically non-conductive fluid—the main vendors worth evaluating are:

• grcooling.com — A major specialist in single-phase immersion cooling, with rack-based systems such as ICEraQ SX. It also has partnerships for immersion-ready Dell, Supermicro, Cisco and other infrastructure.

• DCX / Midas Immersion — Additional specialists worth considering for specific deployments, particularly if you're looking for alternatives to the larger vendors.

Which approach fits overheating servers?

For a data center experiencing peak-load thermal problems, I'd first determine your rack power density:

Immersion isn't necessarily the best answer for every overheating problem: it can require changes to servers, fluids, rack infrastructure, maintenance procedures and heat-rejection equipment. For an existing facility, retrofit complexity and server compatibility are often as important as the cooling capacity itself.

If you tell me your approximate rack kW, number of racks, GPU/server type, and whether this is a retrofit or new build, I can narrow these down to 3–4 vendors and compare their architectures, capacity, fluid type, retrofit requirements, and likely fit.

Top providers of data center immersion cooling solutions include specialized firms like Green Revolution Cooling (GRC) and Submer , alongside major infrastructure vendors expanding into high-density thermal management.

When servers overheat during peak usage, transitioning from traditional air conditioning to single-phase or two-phase liquid immersion cooling submerges IT hardware directly into a thermally conductive, dielectric (non-conductive) fluid.

If you'd like, share:

• Your current rack power density (kW per rack)
• Whether you prefer single-phase or two-phase fluid technology

I can help narrow down which vendor architecture fits your facility layout.

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.

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.

• 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.
