SR40 V3 FAQ

Short answer Yes — the SR40 V3 ships with a fully integrated, industrial-grade power distribution system. The PDUs are engineered for the continuous, high-amperage draw of high-density computing loads without derating, with breaker protection, phase balancing, and integration into the container's thermal management PLC. Integrated industrial-grade PDU Continuous high amperage, no derating Breaker protection and phase balancing Tied into the thermal PLC What the integrated electrical system covers High-amperage distribution hardware inside the container. Sized for continuous load. PDUs handle the sustained high-amperage draw of dense computing hardware without derating. Comprehensive breaker protection. Circuits are protected across the distribution system. Phase balancing. Three-phase supply is kept stable across the load. Electrical and thermal are integrated. The PDU works with the container's PLC so power and cooling respond together. The dense load the distribution system feeds. Power systems are installed and tested at the factory.

Short answer Two loops, two fluids. The primary loop serving the hardware runs pure, deionized or specially treated water for maximum thermal conductivity and corrosion protection. The external loop to the dry towers runs a water-and-industrial-glycol mixture formulated for the site's minimum ambient temperature. Primary loop: deionized or treated water Prevents galvanic corrosion in hardware Secondary loop: water + industrial glycol Glycol mix set to site minimum temp Why each loop uses a different fluid The two-loop arrangement: treated water inside, glycol mix outside. Primary loop optimizes heat transfer. Water has the highest specific heat capacity of the practical options. Treated water protects the hardware. Deionized or specially treated water prevents galvanic corrosion inside the mining hardware. Secondary loop buys freeze protection. Industrial glycol keeps the outdoor loop liquid at the region's minimum temperatures. There is a trade-off. Higher glycol concentrations add protection but slightly reduce heat dissipation efficiency. Hardware side — protected by treated water. Outdoor side — glycol mix for freeze protection. Concentration is engineered, not generic Glycol ratio is set against your deployment region. The mixture is formulated for the minimum ambient temperature at the site — and reviewed against coolant degradation guidance over the operating cycle.

Short answer Yes — the SR40 V3 is inherently modular. Multiple containers can be deployed in a cluster for multi-megawatt sites, either plumbed individually to dedicated dry cooling towers or engineered into a larger, centralized closed-loop dry cooling array. Inherently modular architecture Individual or centralized plumbing Built for multi-megawatt sites Same interface at every block Two clustering topologies TopologyHow it worksBest suited to Individual plumbingEach container is plumbed to its own dedicated dry cooling tower.Maximum isolation — a fault in one loop stays contained to one container. Centralized closed-loop arrayContainers tie into a shared dry cooling array.Higher density and shared heat rejection with fewer towers on site. What stays constant as the cluster grows A multi-megawatt site built by repeating the same container block. The container does not change. Each block keeps the same standardized manifold and interface. Topology is a site decision. The choice between individual and centralized plumbing follows your space and redundancy requirements. Growth is additive. Capacity scales block by block without redesigning deployed units. Standardized rows ready to repeat. The same pattern repeated across the site.

Short answer The SR40 V3 is designed for low-touch operation. Routine maintenance is mainly coolant quality checks, cleaning or replacing inline particulate filters, and inspecting quick-connect fittings — with pumps and heat exchangers positioned for fast, direct access. Low-touch daily operation Coolant quality checks Inline particulate filter service Accessible pumps and heat exchangers The routine service items Coolant quality Water quality parameters — pH, conductivity, inhibitors and microbial levels — drive replacement, not the calendar. Degradation typically shows over a 1–2 year cycle. Inline particulate filters Cleaned or replaced based on filter differential pressure, which the monitoring platform makes visible. Quick-connect fittings Inspected periodically for integrity to catch seeps before they become leaks. Pumps and heat exchangers All critical mechanical components are positioned for easy access, cutting the time needed for servicing or replacement. Daily site labor is close to zero No daily on-site intervention is required. Management relies on backend data monitoring; monthly visual inspections cover filter pressure differentials, quick coupling integrity and dry cooler fin cleanliness. Designed so servicing stays simple Hardware racks stay in place while the cooling side is serviced. Access is a design requirement. Components were placed for reachability, not packed for density alone. Short MTTR. Simplified procedures keep mean time to repair low. Manifold and hose routing is laid out for service access. Dry cooler fins are part of the monthly visual inspection. Related questions Daily manual maintenance and key inspection items? How to determine coolant replacement and degradation?

Short answer The SR40 V3 carries N+1 redundancy on its primary circulation pumps. The integrated PLC monitors pressure, flow and fluid temperature continuously — and if a primary pump fails, the standby pump engages automatically while operators are alerted, preventing hardware throttling or emergency thermal shutdown. N+1 redundancy on primary pumps PLC watches pressure, flow and temperature Standby pump engages automatically Operators alerted on every failover What happens when a primary pump fails Deviation is detected — the PLC flags pressure or flow outside specification. Standby engages — the backup pump starts automatically — no manual intervention needed. Operators are alerted — the event is raised to the monitoring platform for follow-up service. Load keeps running — cooling continues without throttling hardware or triggering a thermal shutdown. Why the loop is designed this way The pump and manifold arrangement inside the container — the path redundancy protects. Continuity is the design target. Maintenance downtime directly impacts profitability, so critical paths carry redundancy. Service without shutdown. A failed pump can be serviced while the standby keeps the loop running. Monitoring is continuous. The PLC supervises system pressure, flow rates and fluid temperatures around the clock. The load that stays online through a pump failover.

Short answer Site preparation is deliberately minimal. The SR40 V3 needs a level, load-bearing concrete pad or engineered pier system, primary electrical feeds to the integrated power distribution unit, and standard plumbing tie-ins between the container's heat exchangers and the external dry cooling towers. Level, load-bearing pad or pier system Primary electrical feeds to the PDU Tie-ins to external dry cooling towers Minimized footprint, rapid install Site readiness checklist Level, load-bearing surface — a hardened concrete pad or engineered pier system rated for the container. Primary electrical feeds — sized to the integrated power distribution unit (PDU). Heat-rejection plumbing — standard tie-ins connecting the container's primary heat exchangers to the external dry cooling towers. Access for delivery and service — space for hoisting equipment and for routine servicing around the unit. What minimal site work looks like Units set on a prepared surface — no permanent building required. Everything arrives complete. ISO-standard 40HQ modules ship by sea, road or rail. Fast to first power. A skilled team commissions a standard container in 2–3 days; a 12-miner micro skid connects within half a day. Any flat outdoor site. The same site spec repeats for each additional block as the site grows. Installed units on a prepared site. Repeated site pattern across a larger deployment.

Short answer The SR40 V3's closed-loop architecture isolates computing hardware from outside dust and humidity. For extreme heat it pairs with high-efficiency dry cooling towers or adiabatic solutions; for freezing conditions the secondary loop runs an industrial glycol mixture with automated temperature regulation. Closed loop blocks dust and humidity Heat handled by dry towers or adiabatic Cold handled by glycol secondary loop Automated intake temperature regulation What each condition demands from the system ConditionHow the system responds Extreme ambient heatHigh-efficiency dry cooling towers carry the load, with adiabatic cooling added where the site requires it. Freezing environmentsThe secondary loop is configured with industrial glycol mixtures and automated temperature regulation to prevent freezing. Dust and humidityThe closed-loop hydro architecture keeps sensitive computing hardware isolated from outside air. Miner intake temperatureAutomated regulation holds intake temperatures in spec while the loop handles the outdoor extremes. Engineered for the site's climate, not a lab Containers and dry coolers exposed to full ambient conditions on site. Validated in operational deployments across extreme environments, not only in controlled lab conditions.

Short answer The SR40 V3 is built for the extreme thermal density of modern hydro-cooled ASIC miners and HPC hardware. Optimized fluid dynamics and high-capacity internal manifolds move heat into the secondary loop, where dissipation capacity is set by the paired dry cooling tower and the site's ambient conditions. Built for hydro ASIC and HPC densities Optimized fluid dynamics High-capacity internal manifolds Capacity set by dry tower + ambient How heat moves through the system SR40 V3 container paired with a dry cooling tower — heat is rejected in the second loop. Heat is captured at the rack. The primary loop picks up heat directly from hydro-cooled hardware. Transferred to the secondary loop. High-capacity manifolds carry the load out of the container. Rejected by the dry cooling tower. Tower sizing — not the container — sets the megawatt ceiling. Quoted per project.
