COMPACT HYDRO-COOLING SYSTEM · CABINET SERIES

SR 20-M

Compact hydro-cooling for up to 20 miners.

A fully integrated, factory-built system designed for high-density mining. Capable of housing up to 20 hydro miners and dissipating over 200 kW of heat, it achieves a design PUE below 1.05. The entire system is delivered as two plug-and-deploy modules for rapid setup.

Flexible Deployment

One system. Two ways to deploy.

The SR 20-M features a split-type structural design that adapts to your site — not the other way around.

01

Indoor Split Configuration

Place the miner cabinet inside your facility with the dry-cooler container outdoors — the right fit where climate control, security, or existing buildings are part of the picture.

  • Miner cabinet deploys inside the facility
  • Dry cooler positioned outdoors
  • Adapts to constrained or existing sites
02

Outdoor All-in-One Configuration

Deploy the complete system outdoors as a single integrated unit — the fastest path from delivery to full operation on open sites and greenfield locations.

  • Complete system outdoors as one unit
  • Fastest route to full commissioning
  • Ideal for open sites and rapid scale-out
System Architecture

Engineered as one system, not assembled from parts

Power distribution, networking, the miner rack, and the coolant distribution unit arrive pre-integrated and pre-tested as a single cabinet.

01 / PDC

Power Distribution

Main breaker 400 A with 20 × 20 A miner breakers. High-reliability design with high-grade copper bar connections throughout.

02 / NETWORK

Network Switch

2 × 24-port Gigabit switches integrated in the cabinet — network-ready from day one.

03 / MINER RACK

Miner Rack

20 high-strength slots on a reinforced frame with all cabling built in — optimized for convenient maintenance.

04 / CDU

Coolant Distribution

PLC cabinet with a 70 L all-in-one water tank and a 20 m³/h pump. Real-time monitoring and control of operating frequency.

Built-in makeup water tank with real-time level monitoring Circulating filter keeps the medium clean Manual valves for quick isolation during maintenance
Why SR 20-M

A lower cost per deployed megawatt

The compact SR 20-M is built to cut the three biggest line items in small- and mid-scale deployments: shipping, land, and on-site labor.

40%

Lower Transportation Costs

Up to 40% lower shipping cost than a traditional 20-foot container solution — same power capacity, smaller logistics footprint.

56%

Less Land Occupied

At the same power capacity, the SR 20-M occupies up to 56% less land than a 20-foot container deployment — land that stays available for the next expansion phase.

½

Less Work, Less Time

Highly prefabricated modular design dramatically reduces the amount of work and time required on site — from delivery to commissioned operation.

Intelligent Control

Automated System Monitoring. Hands-Free Reliability.

The PLC-based Intelligent Control Console keeps the SR 20-M stable around the clock — and gives operators full visibility when it matters.

  • Precise thermostatic control
  • Adaptive flow control
  • Automatic preheating control
  • External cooling system linkage
  • Historical alarms & operation records
  • Historical performance data curves
  • Multi-point fault alarm system
  • Low water level & leak alarms
  • Auto load reduction & recovery on high temp
  • Unified component status overview
  • O&M operation permission groups
  • Indoor & outdoor environment monitoring
