Certified Safety Meets Network Modernization: ATX Achieves UL1973 Certification for Areca™ Hybrid Supercapacitor

Future ready energy storage empowers service providers to upgrade backup power systems with confidence

SAN DIEGO--(BUSINESS WIRE)--ATX Networks, an innovation leader in broadband access, media distribution, and sustainable energy storage, today announced that its Areca™ Hybrid Supercapacitors — featuring technology developed in partnership with SuperCap Energy — have achieved UL1973 certification. This milestone pairs proven safety with future-ready performance, giving operators the confidence to modernize backup power systems across their networks.

Recognized globally, UL1973 is the critical safety benchmark for stationary energy storage systems, signifying rigorous third-party testing against potential hazards. With this certification, Areca Hybrid Supercapacitors offer inherently safe operation with zero risk of thermal runaway, wide operating temperature ranges, 100% depth of discharge capability, and a design life of 20+ years with minimal maintenance — dramatically lowering total cost of ownership over the product lifecycle.

"Hybrid Supercapacitors are reshaping what safe, reliable backup power looks like," said Julie Davis, VP of Sales, Energy Storage at ATX Networks. "UL1973 certification removes a key barrier for operators evaluating next-generation backup power. We're already seeing strong interest from data center and telecom customers who want the safety and lifecycle advantages Areca delivers."

Initial coverage focuses on the 7.68kWh Areca rackmount configurations, with additional products to follow as certification coverage expands. The Areca family serves datacenters, remote outside plant facilities, and mobile cell sites, where safety, reliability, and deployment efficiency are paramount. For availability details and technical specifications, contact ATX Networks directly.

UL1973 certification encompasses cell consistency, short circuit protection, overcharge/overdischarge protection, cycle life, vibration/shock resistance, and ingress protection ratings — a comprehensive validation that simplifies approvals and accelerates market acceptance for critical deployments.

Areca's Hybrid Supercapacitor architecture eliminates hazardous off-gassing and chemical leak risks common to traditional batteries, supports full recyclability and reduced replacement frequency, and helps operators advance corporate sustainability goals without compromising network resilience.

Why operators are choosing Areca:

• UL1973 certified safety and reliability
• No thermal runaway or chemical risk
• 20+ year design life and 20,000+ lifecycles for lower TCO
• Resilient performance across harsh environments and wide temperature ranges
• Streamlined approvals for data centers, outside plant, and mobile sites
• Minimal maintenance enabling teams to refocus on high value work

ATX continues to build on a strong safety foundation. Prior certifications include UL810a compliance and successful UL9540A thermal propagation testing for its Hybrid Supercapacitors. Together with recent updates to NFPA855 recognizing the lower fire-risk profile of Hybrid Supercapacitors, these developments further simplify the compliant deployment of Areca solutions.
