Core Advantages

Unlike traditional cooling equipment that relies on real-time heat rejection during scorching afternoons, the ACS operates on a two-phase "Store Cold by Night, Discharge by Day" cycle:

• Off-Peak Nighttime Charging: When ambient temperatures drop and grid power is cheapest, the ACS draws an ultra-low 40kW of electrical input to charge its internal thermal core at a 100kW rated cooling rate, locking in 8 GJ (1.91 million kcal) of stored cooling reserve.
• Peak Daytime Discharging: During the 6 hottest hours of the day (when ambient temperatures soar to 50°C–55°C and standard dry coolers lose efficiency), the ACS discharges this stored energy directly into the miner loop, allowing Antminer hydro containers to run at 100% full hashrate without thermal throttling or shutdowns.

Key Differences:

• Vs. Dry Coolers: Dry coolers fail when ambient air exceeds 42°C–45°C due to shrinking heat exchange margins. ACS bypasses this bottleneck by releasing pre-chilled energy regardless of outdoor ambient heat.
• Vs. Wet Cooling Towers: Open evaporative towers consume thousands of gallons of water daily and cause scaling. ACS utilizes a 100% sealed closed loop with absolute zero operating water consumption.

How can a system with only 40kW rated power assist in cooling a massive 1.2MW–1.5MW hydro container?

The ACS does not replace your primary cooling system; it acts as a concentrated peak-shaving thermal booster. While your main dry cooler or cooling loop handles baseline heat dissipation, the ACS injects its stored 8 GJ (1.91 million kcal) of reserve specifically during the 6 hottest hours of the day.

By discharging 8 GJ across 6 hours, the ACS delivers an effective ~370 kW of supplemental peak cooling capacity directly to the miner loop. Because this chilling capacity was slowly accumulated and stored overnight using low 40kW input power, it allows you to overcome extreme daytime heat spikes without requiring a massive, expensive electrical substation upgrade.

How is "zero operating water consumption" achieved, and why is this critical for desert sites?

Unlike open evaporative cooling towers that continuously lose water to evaporation and purge cycles, the ACS uses a 100% hermetically sealed thermal loop. The internal storage medium charges and discharges through closed-circuit heat exchangers without any fluid exposure to the ambient atmosphere.

For arid mining hubs like the Middle East, West Texas, or Northern Africa, zero operational water consumption eliminates water trucking and hauling costs, avoids costly municipal water rights permitting, prevents chemical biocide expenses, and completely eliminates scale accumulation on miner cold plates.

Can ACS guarantee miner stability when outdoor temperatures reach 50°C–55°C?

Yes. The ACS is officially engineered for ambient operating limits up to 55°C, specifically designed to deliver 6 hours of sustained peak cooling at 50°C ambient.

In standard setups, ambient air above 42°C causes coolant return temperatures to exceed ASIC safe operating thresholds. By blending the stored 8 GJ chilled reserve into the supply header, the ACS artificially depresses the miner inlet water temperature to safe operating parameters (typically ≤35∘C≤35∘Cto 40∘C40∘C), fully protecting hashboards from heat-induced throttling or thermal shutdown.

How does ACS connect to ANTSPACE HW7, and what is required for an HD5 or HK3 "fit assessment"?

• ANTSPACE HW7 (Standard Application): The ACS features native, plug-and-play hydraulic and electrical interfaces pre-matched to the HW7 container. Connection involves standard industrial flange tie-ins and communication cabling.
• ANTSPACE HD5 / HK3 (Fit Assessment Required): Deploying with HD5 or HK3 is fully viable, but requires a brief engineering review. Our technical team evaluates your site’s hydraulic pipe diameters, dry cooler flow rates (>85 m3/h>85 m3/h on HK3), pump head pressures, and local summer temperature profiles to provide a customized hydraulic tie-in kit and bypass valve schematic.

How can ANT Cold Storage (ACS) be applied to enterprise liquid-cooled data centers and AI computing clusters?

As modern AI clusters and high-performance computing (HPC) facilities adopt high-density Direct-to-Chip (DLC) liquid cooling (often exceeding 40kW–100kW+ per rack), they face severe peak electricity demand charges and thermal strain during hot summer afternoons. The ACS integrates into data center environments to provide three critical advantages:

• Peak Shaving & Grid Cost Optimization: By storing 8 GJ of cold reserve during cheap off-peak nighttime hours and discharging it during peak daytime hours, the ACS significantly reduces daytime chiller runtime, slashing expensive utility demand charges and driving down facility PUE.
• Zero-Water ESG Compliance (WUE = 0): Many jurisdictions now prohibit or heavily penalize evaporative cooling towers due to water scarcity. The ACS’s 100% sealed closed loop enables hyperscale and enterprise facilities to maintain full cooling performance with zero operational water consumption, directly meeting strict corporate Water Usage Effectiveness (WUE) sustainability goals.
• Seamless CDU Integration: Following an engineering fit assessment, the ACS ties directly into the data center’s primary chilled-water loop or central Coolant Distribution Unit (CDU) via standard plate heat exchangers, acting as an active thermal buffer without requiring any modifications to server-level cold plates.
