Immersion ASIC Hosting Middle East — Single-Phase + Dual-Phase, Built for the Gulf
MinersHub runs single-phase and dual-phase immersion ASIC hosting at scale across the Middle East. Tier 03 immersion is our largest deployment tier — sub-15 J/TH hardware sits in dielectric fluid and runs at factory-rated efficiency without thermal throttling, even when ambient outside hits 48 °C. We design the immersion stack ourselves: tank, fluid, manifold, CDU, and the cross-rack heat-rejection loop. The same Al Ain repair bench services every immersion-modded unit on every Gulf site we run — UAE, Oman, KSA, Bahrain, Kuwait, and Qatar.

Immersion ASIC hosting across the Middle East — UAE, Oman, KSA, Bahrain, Kuwait, Qatar
TL;DR: MinersHub is the only Middle East operator with on-soil immersion infrastructure in UAE, an active Oman deployment corridor (Sohar / Muscat / Duqm / Salalah), and engineered support paths into KSA, Bahrain, Kuwait, and Qatar. Same $0.067/kWh anchor across the region. Same 98% Tier 03 SLA. Same Al Ain repair bench services every immersion-modded unit on every Gulf site we run.
Most “Middle East” immersion vendors are either tank manufacturers shipping equipment to a colocation provider, or single-country operators reselling capacity. We design, build, and operate the entire stack ourselves on the ground in the Gulf:
- UAE (Dubai, Abu Dhabi, Al Ain, Sharjah, Ras Al Khaimah). Primary immersion footprint. 7-emirate coverage with the Al Ain repair bench as the only on-soil ASIC service center in the region.
- Oman (Sohar, Muscat, Duqm, Salalah). Active Sohar deployment corridor with a weekly Sohar → Al Ain repair shuttle so Oman-hosted immersion units route to UAE-licensed warranty support without you shipping internationally.
- KSA (Riyadh, Dammam). Engineered immersion deployments under contract with KSA-spec dielectric loops + 50 °C ambient resilience.
- Bahrain (Manama, Sitra industrial). Coastal-humidity-spec stainless-steel tanks; OEM warranty path preserved through the immersion conversion.
- Kuwait + Qatar. Site assessment + custom immersion build available on enterprise contracts (1 MW+).
Cross-border deployments use a single contract, single SLA, single billing entity. You don’t end up with five vendor relationships across the Gulf — one MinersHub contract covers the entire regional immersion estate, and one repair bench handles every warranty event from Riyadh to Muscat to Manama.
Single-phase vs dual-phase immersion — what actually matters at fleet scale
TL;DR: single-phase immersion uses a non-boiling dielectric oil that absorbs heat conductively (lower CapEx, simpler ops). Dual-phase uses an engineered fluorinated fluid that boils at the chip surface and condenses on a heat exchanger (higher CapEx, much higher density). Most GCC fleets land on single-phase; dual-phase pays off only above ~150 kW per tank.
| Dimension | Single-phase immersion | Dual-phase immersion |
|---|---|---|
| Heat transfer | Conductive (oil to coil) | Phase-change (boil + condense) |
| Fluid type | Synthetic dielectric oil (mineral-style) | Engineered fluorinated fluid (3M Novec / equiv) |
| Density support | Up to ~50 kW/m² | Up to ~250+ kW/m² |
| CapEx (per slot) | From $800 | 2-4× single-phase |
| Operational complexity | Lower — pump, manifold, oil top-up | Higher — sealed tank, condenser, fluid recovery |
| Best for | Most ASIC fleets, 50 kW – 1 MW deployments | Large-scale operators, AI/HPC mixed loads, 1 MW+ density |
| MH support | Standard offering | Available on 1 MW+ contracts |
Hydro cooling vs immersion cooling for ASICs — when to pick each
TL;DR: hydro is closed-loop water cooling (cold plates on hashboards, manifolds, CDUs). Immersion submerges the whole board in dielectric fluid. Hydro is cheaper to enter and works for hydro-native ASICs like S21 Hyd; immersion is the right answer when you want to push hashboards beyond hydro’s safe envelope or when you’re standardising on air-cooled SKUs and modding them for density.
| Dimension | Hydro cooling | Immersion cooling |
|---|---|---|
| What it cools | Hashboards only (cold plates) | Entire board + PSU + control board |
| Hardware needed | Hydro-native SKU (S21 Hyd, M53/M63 hydro) | Any ASIC + immersion conversion mod |
| Coolant | Treated water-glycol mix | Synthetic dielectric oil OR fluorinated fluid |
| Density per m² | ~30–50 kW | ~50–250 kW |
| Setup CapEx (per slot) | $750 / miner one-time | From $800 / slot, custom tank |
| OEM warranty | Native — fully preserved | OEM-blessed mod path required |
| Best fleet size | Up to 1 MW | 1 MW+ density, AI/HPC mixed loads |
| MH SLA | 98% (hydro tier) | 98% (Tier 03 immersion) |
- Pick hydro when: you’re running hydro-native SKUs (Antminer S21 Hyd, S21+ Hyd, S21e Hyd; MicroBT M53/M63 hydro), you have <1 MW total fleet draw, and you want predictable factory-rated efficiency without modifying hardware.
- Pick immersion when: you’re standardising on air-cooled SKUs and modding them for density, you want to push beyond factory-rated thermal envelope, you have 1 MW+ total fleet draw, or you’re preparing for AI/HPC mixed-workload colocation in the same room.
- Hybrid (most operators): run hydro on the production Antminer fleet and immersion on the experimental tier where you’re testing aggressive efficiency. We support hybrid sites without forcing standardisation — both tiers in the same suite, one contract, one SLA.
The wrong choice locks you into a multi-year setup that doesn’t scale with your roadmap. Most fleets we onboard end up running hydro for the production tier + immersion for the density experiment — and we provision both in the same suite without forcing a vendor switch.
Why MinersHub immersion deployments outperform off-the-shelf installs
- Tank + fluid + control system are co-engineered, not bolted together. Most regional immersion installs use a third-party tank, generic dielectric, and a hashboard controller that wasn’t designed for the boil/condense cycle. We design the tank, spec the fluid, tune the manifold flow rate, and validate every immersion conversion against our own 24-hour soak test before putting it on the production floor.
- Immersion thermistors stay OEM-supported. Off-the-shelf installs replace the thermistor with a generic equivalent — Bitmain and MicroBT void the warranty the moment they detect it. Our conversion path uses OEM-blessed thermistor swaps so the 12-month factory warranty stays valid through the immersion mod, on every unit.
- One repair bench, one warranty entity, one shipping address. Every immersion-modded ASIC across UAE, Oman, KSA, Bahrain, Kuwait, and Qatar routes back to the Al Ain repair bench. You don’t ship internationally, you don’t lose a warranty claim to a freight-forwarder, and you don’t pay UAE customs twice.
- Sub-15 J/TH efficiency held year-round. Our dielectric loop + heat-rejection design hold factory-rated efficiency even when GCC ambient breaks 48 °C. Off-the-shelf installs typically derate by 12–18% in summer; ours don’t, because the heat-rejection side was spec’d for the climate, not retrofitted to it.

Why GCC-spec’d, not bolted on
- Dielectric fluid grade. Off-the-shelf mineral oil works at 25 °C ambient. GCC ambient hits 48 °C — fluid degrades, viscosity shifts, pumps strain. We spec viscosity-stable synthetic dielectrics with high flash point + thermal stability for the climate.
- Tank materials. Aluminum tanks corrode in coastal humidity (Sohar, Abu Dhabi waterfront, Manama). Our default is stainless steel + corrosion-resistant gaskets.
- Heat-rejection loop. Cold-side air-cooled rejection loops hit thermal limits in summer. We spec wet-bulb-tolerant heat exchangers + adiabatic cooling on the rejection side.
- Warranty path. OEM warranty is voided when third parties replace immersion thermistors. We use OEM-blessed mod paths so Bitmain / MicroBT 12-month warranty stays valid through the immersion conversion.
Frequently asked questions
What’s the minimum order for immersion at MinersHub?
2 units to enter Tier 03 immersion hosting. 6 units to commission a custom tank build with our infrastructure team.
Single-phase or dual-phase — which should I pick?
Single-phase for most GCC fleets up to 1 MW. Dual-phase makes sense at 1 MW+ density or when you’re co-locating AI/HPC compute in the same suite. We design and operate both; the choice is driven by deployment density target, not preference.
Does immersion void my OEM warranty?
It can — the failure mode is “third party replaces immersion thermistor without OEM blessing → OEM voids the unit.” We use OEM-blessed conversion paths (Bitmain immersion guidance, MicroBT hydro/immersion line) so warranty stays valid through the mod. We hold and process OEM warranty claims on your behalf.
What’s the deployment timeline for an immersion fleet?
4–12 weeks from greenlight: 2–4 weeks tank fabrication, 1–2 weeks fluid + manifold + CDU build, 2–4 weeks fleet immersion conversion + commissioning + 24-hour soak test. Discovery + design adds 4–8 weeks before contract.
How is immersion priced compared to hydro?
Same $0.067/kWh anchor for power. Setup is also $600/slot. Custom tank fabrication adds $800+/slot one-time vs hydro’s $750/miner one-time — pricier per slot but density math often beats hydro at 1 MW+.
Can I tour an active immersion farm?
Yes, by appointment with 48-hour notice. Most fleet-scale clients tour Tier 03 sites before signing because immersion is a meaningfully different operational model than hydro.
Does MinersHub support immersion deployments outside the UAE?
Yes — across UAE (primary), Oman (Sohar corridor active), KSA, Bahrain, Kuwait, and Qatar. Single contract, single 98% SLA, single billing entity. Repair routes back to the Al Ain bench via a weekly shuttle so you don’t ship units internationally.
How does GCC ambient temperature (48 °C+) affect immersion fluid lifespan?
Off-the-shelf mineral oil degrades fast above 40 °C ambient — viscosity climbs, pump load goes up, and fluid has to be replaced every 18–24 months. We spec viscosity-stable synthetic dielectrics with high flash point + thermal stability rated for sustained 48 °C+ operation. Real-world fluid replacement intervals on our floor are 4–6 years for single-phase and 7–10 years for sealed dual-phase.
What’s the realistic uptime difference between immersion and air at MinersHub?
Air-cooled Tier 01 SLA is 95%. Hydro Tier 02 is 98%. Immersion Tier 03 is also 98% — but the failure modes shift: immersion eliminates fan-failure, dust-clogging, and thermal-throttling outages, but adds tank-leak and CDU-failure risk. Net: similar SLA number, very different failure-mode distribution. Immersion wins decisively when summer ambient is the bottleneck.
Can immersion units run AI/HPC workloads alongside ASIC mining?
Yes — dual-phase immersion is increasingly used to colocate H100/H200 GPU compute alongside ASIC fleets in the same room. We design dual-phase suites that support mixed thermal envelopes (300–700 W chip TDP for ASICs, 700+ W for HPC). Useful for operators preparing for AI workload diversification without rebuilding the room.
