Industries We Serve
Engineered enclosure systems for four critical-environment verticals — purpose-built for the safety, code, and integration requirements of each.
Battery Storage
Utility-scale BESS, data center UPS, microgrid, and commercial battery rooms. UL-certified containment with NFPA 855 compliance.
Data Centers
Prefabricated data center enclosures, switchgear rooms, and electrical equipment buildings — engineered for uptime and rapid deployment.
Hazardous Locations
UL-certified C1D1/C1D2 enclosures for solvent extraction, chemical processing, pharmaceutical, and industrial flammable-storage applications.
Clean & Specialty Environments
ISO-aware modular cleanrooms, GMP-compliant indoor and outdoor booths, and controlled-environment laboratories.
What Makes AEL Different
Four credentials that separate AEL from generic prefab enclosure suppliers — earned, documented, and verifiable.
UL-Certified Manufacturer
Among the few UL-listed C1D1/C1D2 hazardous-location enclosure manufacturers in the United States. UL 508A control panel certified.
Integrated Safety Systems
Fire suppression, gas detection, explosion-resistant ventilation, and fire-rated assemblies engineered as one system — not bolt-on accessories.
Built in California
Designed, fabricated, and tested in Santa Rosa, CA. No outsourcing, no overseas component sourcing — verifiable U.S. manufacturing.
Custom-Engineered to Spec
Every enclosure custom-engineered to the customer's site, code requirements, and integration plan. Stamped drawings included.

Frequently Asked Questions
What does Advanced Extraction Labs manufacture?
AEL designs and manufactures integrated enclosure systems for critical environments — battery energy storage containers (Sentinel, Energy Cubes), prefabricated data center enclosures, switchgear rooms, UL-certified C1D1/C1D2 hazardous location enclosures, modular cleanrooms, and specialty containment buildings. Every system is custom-engineered to the customer’s site, code requirements, and integration plan, and built in our Santa Rosa, California facility.
Is AEL a UL-certified manufacturer?
Yes. AEL is among the few U.S. manufacturers UL-listed for C1D1/C1D2 hazardous location enclosures, with UL 508A certification for our control panels. UL listing is a third-party validation that the entire enclosure assembly — not just individual components — meets the National Electrical Code and NFPA standards. This is a significant differentiator from suppliers that integrate UL-listed parts but lack listing for the complete enclosure.
What industries does AEL serve?
AEL’s primary verticals are battery energy storage (utility-scale BESS, data center UPS, microgrid, commercial battery rooms), data centers and electrical infrastructure, hazardous-location applications (chemical processing, pharmaceutical, solvent extraction, industrial flammable storage), and clean and specialty environments (ISO cleanrooms, GMP-compliant labs). Customers include Boeing, SpaceX, MacDermid Alpha Electronic Solutions, and PLZ Corp.
Are your products engineered or off-the-shelf?
Custom-engineered. Every AEL enclosure is sized, configured, and engineered to the customer’s specific site conditions, throughput requirements, code jurisdiction, and integration plan. We provide stamped layout drawings, equipment schedules, ventilation and fire calculations, and full submittal packets for permitting.
What integrated safety systems do AEL enclosures include?
Depending on the application: fire suppression (clean agent or dry chemical), gas detection, explosion-resistant ventilation, fire-rated wall and roof assemblies (1-hour to 3-hour), pressure relief, hazardous location electricals (NEC Article 500), thermal runaway detection (battery storage), and environmental monitoring. Safety systems are engineered as one integrated package, not bolt-on accessories.
Where are AEL enclosures manufactured?
Designed, fabricated, factory-tested, and shipped from our Santa Rosa, California facility. No overseas component sourcing for safety-critical parts. We ship complete prefabricated units across the United States — significantly faster deployment than traditional onsite construction.
Do you handle permitting and Authority Having Jurisdiction (AHJ) approvals?
Yes. We provide stamped drawings, equipment cut sheets, ventilation calculations, fire suppression schematics, and full submittal packets sized for plan review. Our engineering team responds to AHJ plan-check comments and supports the permitting process. Final approval rests with your local AHJ.
How do I request a quote?
Call (888) 502-6695 during business hours (Monday through Friday, 8 AM to 6 PM Pacific) or submit a request through our contact form. Provide your application (battery storage, data center, hazloc, cleanroom), approximate site dimensions, throughput or capacity requirements, and project timeline — our engineering team will respond within one business day with sizing recommendations and a preliminary quote.
