Accepted Answer

Standard configuration features high-density smart PDUs with grouped control. However, each mining unit maintains independent protection via dedicated miniature circuit breakers (MCBs) for precise control.

Question 20

How to ensure consistent flow and pressure across all mining units using balancing valves and monitoring tools.

Accepted Answer

Hydraulic balance between the nearest and farthest units is achieved via branch balancing valves, flow meters, and differential pressure controls. Each circuit uses regulating ball valves and monitoring instruments to ensure uniform flow distribution.

Question 21

Preventing dry cooler freezing at -20°C via glycol concentration and VFD controls without mandatory heating.

Accepted Answer

In extreme cold (-20°C), freeze protection prioritizes ethylene glycol-based antifreeze and VFD fan control. Electric/electromagnetic heating modules are not mandatory; they serve only as auxiliary de-icing tools. A closed-loop system with properly concentrated glycol provides full protection.

Question 22

Daily water usage estimates for cooling towers and dry coolers per 100kW heat load in 24h operation.

Accepted Answer

Under a 100kW load with 24h operation:Closed-circuit cooling tower: ~4.0–4.5 tons/day.Dry cooler + evaporation pad: ~0.8–1.2 tons/day.

Question 23

Cooling solutions for 38°C+ environments. Selecting dry coolers vs. cooling towers based on wet-bulb temperature analysis.

Accepted Answer

Besides evaporation pads, misting/spray systems can be deployed to manage extreme ambient heat. When determining whether to supplement with a dry cooler or transition to a closed-circuit cooling tower, the decisive factor is the local maximum wet-bulb temperature.If the wet-bulb temperature approaches the maximum allowable inlet water temperature of the mining equipment, a closed-circuit cooling tower is necessary to leverage evaporative cooling. Otherwise, a dry cooler may suffice for auxiliary heat dissipation based on the specific equipment requirements and fluid temperature differentials.

Question 24

Yes, the container features a built-in, industrial-grade PDU engineered for high-density loads.

Accepted Answer

The SR40 V3 comes equipped with a fully integrated, industrial-grade power distribution system.

The electrical infrastructure includes comprehensive breaker protection, phase balancing, and integration with the container's thermal management PLC to ensure safe operation.

Question 25

The system operates on treated water or specific water-glycol mixtures depending on the deployment climate.

Accepted Answer

The internal (primary) loop typically utilizes pure, deionized, or specially treated water to ensure maximum thermal conductivity and prevent galvanic corrosion within the mining hardware. The external (secondary) loop, which connects to the dry towers, typically uses a water and industrial glycol mixture formulated specifically for the minimum ambient temperatures of your deployment region to provide reliable freeze protection.

Question 26

Yes, multiple containers can be daisy-chained or connected to centralized cooling towers for large-scale deployments.

Accepted Answer

Yes. The SR40 V3 is inherently modular. For multi-megawatt sites, operators can deploy multiple containers in a clustered arrangement. These can be plumbed individually to dedicated dry cooling towers, or engineered to tie into a larger, centralized closed-loop dry cooling array, depending on your site's spatial and redundancy requirements.

Question 27

Maintenance is minimal, focusing primarily on fluid quality checks, filter cleaning, and visual inspections.

Accepted Answer

We designed the SR40 V3 for low-touch operation. Routine maintenance primarily involves checking coolant fluid quality, cleaning or replacing inline particulate filters, and inspecting quick-connect fittings for integrity. All critical mechanical components, such as pumps and heat exchangers, are positioned for easy access, minimizing the time required for routine servicing or component replacement.

Question 28

The system incorporates N+1 pump configurations and automated failovers to prevent thermal events.

Accepted Answer

Operational continuity is critical. The SR40 V3 features N+1 redundancy on primary circulation pumps. The integrated programmable logic controller (PLC) continuously monitors system pressure, flow rates, and fluid temperatures. In the event of a primary pump failure, the system automatically engages the backup pump and alerts facility operators, preventing hardware throttling or emergency thermal shutdowns.

Question 29

Deployment requires minimal civil work, primarily a level concrete pad, electrical feeds, and plumbing tie-ins.

Accepted Answer

The SR40 V3 is designed for rapid deployment with a minimized footprint. Site preparation generally requires a level, load-bearing concrete pad or engineered pier system, primary electrical feeds to the integrated power distribution unit (PDU), and standard plumbing tie-ins to connect the container's primary heat exchangers to the external dry cooling towers.

Question 30

When paired with appropriately sized dry cooling towers, the SR40 V3 maintains optimal operating temperatures in extreme climates.

Accepted Answer

The SR40 V3 utilizes a closed-loop hydro cooling architecture that isolates sensitive computing hardware from external environmental factors like dust and humidity. For extreme ambient heat, the system relies on high-efficiency dry cooling towers—or adiabatic cooling solutions if required. For freezing environments, the secondary loop can be configured with industrial glycol mixtures and automated temperature regulation to prevent fluid freezing while maintaining optimal miner intake temperatures.
