NOARK’s UL Solutions power mission-critical Cryptocurrency Mining infrastructure

Powering the Next Generation of Digital Infrastructure with NOARK UL Solutions:

400MW Water-Cooled Mining Container Transformer Project – Texas, USA

Project Overview

In Texas, one of the world’s largest cryptocurrency mining infrastructure manufacturers launched a massive 400MW water-cooled mining container transformer project designed to support high-density digital asset operations at industrial scale. The company is globally recognized for pioneering advanced mining technologies and integrated containerized solutions for cryptocurrency infrastructure.

As demand for digital currencies and decentralized computing continues to grow, operators require highly reliable, energy-efficient, and rapidly deployable electrical infrastructure. Water-cooled mining containers have emerged as a critical innovation, enabling higher computing density, improved thermal management, and lower operational costs in large-scale mining deployments.

To support this landmark project, the client required a complete low-voltage power distribution solution capable of delivering:

• – High reliability under continuous heavy electrical loads
• – UL-certified protection and switching systems
• – Safe maintenance and arc-flash mitigation
• – Modular scalability for rapid deployment
• – Stable operation in demanding industrial environments

NOARK delivered a comprehensive portfolio of UL-certified products that met the project’s power distribution, protection, and operational safety requirements.

Project Highlights

• Project Location: Texas, United States
• Project Capacity: 400MW
• Industry: Cryptocurrency Mining Infrastructure
• Application: Water-Cooled Mining Container Power Distribution Systems

The Challenge

Large-scale cryptocurrency mining operations demand enormous amounts of stable electrical power operating continuously, 24 hours a day. Any interruption, overheating event, or maintenance issue can result in substantial operational losses.

The client needed a robust UL-compliant electrical distribution platform capable of supporting:

• – High-capacity transformer and feeder systems
• – Continuous operation under extreme electrical loading
• – Fast installation and deployment cycles
• – Enhanced personnel safety during maintenance
• – Long-term reliability across multiple containerized mining sites

At the same time, the project required products that could integrate seamlessly into both air-cooled and water-cooled mining container architectures deployed globally.

The NOARK Solution

NOARK supplied a complete UL product series for the project’s low-voltage distribution assemblies and mining container electrical systems.

The overall solution included:

• – Main incoming protection
• – Feeder and branch circuit protection
• – Distribution assemblies
• – Maintenance safety systems
• – Auxiliary and control circuit protection

The result was a highly modular, scalable, and safe power distribution platform optimized for high-density digital infrastructure.

Products Delivered

NOARK Panelboard / Distribution Assembly

The core of the system was a low-voltage distribution assembly integrating Power or Air Circuit Breakers, Molded Case Circuit Breakers, Busbar systems, and other control and protection components. The assemblies were designed to provide reliable power distribution for mining containers operating continuously at high electrical demand.

NOARK A32 Series Power Circuit Breaker

The NOARK A32 Series Power Circuit Breaker served as the main incoming breaker within the panelboard and distribution assembly.

Function in the Panelboard

• – Main power switching and isolation
• – Protection of the entire low-voltage distribution system
• – Fault interruption for high current conditions
• – Coordination between upstream and downstream protection devices
• – Enhanced operational reliability for critical power infrastructure

Its drawout design also simplified maintenance and reduced system downtime during servicing.

NOARK M Series Molded Case Circuit Breakers (MCCBs)

NOARK’s M Series MCCBs were used for feeder and branch circuit protection throughout the distribution system.

Key Functions

• – Protection against overloads and short circuits
• – Reliable isolation of branch circuits
• – Stable operation under continuous industrial loads
• – High interrupting capacity for critical infrastructure applications

These MCCBs played a critical role in maintaining uninterrupted operation and protecting valuable mining equipment.

NOARK Miniature Circuit Breakers (MCBs)

NOARK DIN-rail miniature circuit breakers were installed for auxiliary and control circuit protection.

Applications

• – Control power circuits
• – Monitoring systems
• – Auxiliary electrical components
• – Low-power branch protection

The compact modular design allowed efficient integration into the containerized electrical architecture.

NOARK Rotary Handle Operating Mechanism

The rotary handle operating mechanism enabled safe external operation of breakers without opening the enclosure.

Key Benefits

• – Improved operator safety
• – Secure breaker operation during maintenance
• – Reduced exposure to energized components
• – Compliance with industrial safety practices

This feature was especially important in high-power mining environments where uptime and safety are equally critical.

NOARK ELM10 Energy Limiting Maintenance Switch

To enhance personnel safety, the project incorporated the NOARK ELM10 Energy Limiting Maintenance Switch for arc-flash mitigation.

Key Functions

• – Reduces arc-flash incident energy during maintenance
• – Improves worker safety around energized equipment
• – Enables safer servicing procedures
• – Supports compliance with modern electrical safety standards

The ELM10 provided an additional layer of protection for maintenance personnel operating in high-energy electrical environments.

Project Impact

This project marked a major milestone for NOARK’s UL-certified product portfolio in North America.

As one of the first major cryptocurrency mining infrastructure deployments to adopt NOARK UL air circuit breaker technology at scale, the project demonstrated:

• – The reliability of NOARK products in mission-critical applications
• – The scalability of NOARK solutions for high-density computing infrastructure
• – NOARK’s capability to support rapidly growing digital industries

Following the successful implementation, the client standardized NOARK UL products across both air-cooled and water-cooled mining container platforms, with the solutions also being promoted to deployments in other regions globally.

Strategic Value for NOARK

This flagship deployment strengthened NOARK’s position in the UL-certified power distribution market and showcased the company’s ability to support emerging high-growth industries such as cryptocurrency infrastructure and advanced data processing applications.

The project stands as a strong example of how NOARK delivers:
