Engineered Safety Systems for Critical Environments — Built in California Since 2018
AEL designs and manufactures UL-certified enclosure systems for battery energy storage, data centers, hazardous-location applications, and clean-and-specialty environments. Every system is custom-engineered to the customer's site, code requirements, and integration plan.
Code-compliant safety, custom-engineered into every enclosure.
AEL builds the prefabricated enclosure systems that protect critical equipment and the people who operate it — lithium-ion battery storage, mission-critical data infrastructure, hazardous-process operations, and controlled-environment laboratories.
Founded in Santa Rosa, California, AEL emerged from the botanical-extraction industry as one of the first U.S. manufacturers to earn UL listing for complete C1D1/C1D2 enclosure assemblies — not just the components inside them. That credential, paired with our UL 508A control panel certification, set the engineering standard we now apply across battery storage, data center, and broader hazardous-location markets.
Every AEL enclosure is engineered to a specific site, code jurisdiction, and integration plan. Stamped drawings. Equipment schedules. Ventilation and fire calculations. Submittal packets sized for plan review. Then it's fabricated, factory-tested, and shipped from our facility — ready to land, connect, and start up.
What guides every AEL project
The four operating principles that define how we engineer, fabricate, and deliver every enclosure system.
Safety as a System
Fire suppression, gas detection, ventilation, and fire-rated assemblies designed as one integrated package — not bolt-on accessories.
Code-First Engineering
NFPA, IBC, NEC, and AHJ requirements drive layout, materials, and equipment selection from day one. UL listing, not just UL components.
Custom-Engineered to Spec
Every enclosure sized, configured, and stamped to the customer's site conditions, throughput, and integration plan. No off-the-shelf shells.
U.S. Manufacturing
Designed, fabricated, factory-tested, and shipped from Santa Rosa, California. No overseas component sourcing for safety-critical parts.
Four critical-environment verticals
Each vertical engineered around its distinct safety, code, and integration requirements.
Battery Energy Storage
Sentinel and Energy Cube containers for utility-scale BESS, data center UPS, microgrid, and commercial battery rooms. NFPA 855-compliant containment with thermal-runaway detection and fire suppression.
Data Center & Power Infrastructure
Prefabricated data center modules, switchgear enclosures, and electrical equipment buildings — engineered for uptime, rapid deployment, and predictable factory testing before delivery.
Hazardous-Location Enclosures
UL-listed C1D1 and C1D2 enclosures for solvent extraction, chemical processing, pharmaceutical manufacturing, and industrial flammable storage. NEC Article 500 compliant.
Clean & Specialty Environments
ISO-aware modular cleanrooms, GMP-compliant indoor and outdoor booths, fume hoods, and controlled-environment laboratories for pharma, biotech, and specialty manufacturing.
Engineered for the most demanding environments
AEL enclosures protect critical operations for organizations whose work cannot tolerate downtime, code failures, or safety compromises.
