Premium BESS Container Manufacturing & Global Delivery | TLS Energy International

Battery Energy Storage System (BESS) containers are rapidly becoming the backbone of modern power networks, enabling utilities, developers, and IPPs to stabilise grids and maximise renewable-energy revenue. TLS Energy International—an industry pioneer with over a decade of containerised-solution expertise—delivers turnkey BESS enclosures that shield high-value lithium-ion batteries, optimise thermal performance, and speed up site deployment. The manufacturing, quality-control, and shipping scenes captured in the images above illustrate how each container moves seamlessly from precision fabrication to global delivery while meeting uncompromising performance standards.

Precision Manufacturing, Start to Finish
Every enclosure starts life in our advanced production hall, where marine-grade steel plates are laser-cut, CNC-folded, and robot-welded for millimetre accuracy. Reinforced corner posts, heavy-duty cross-members, and bespoke battery-rack mounts handle today’s high energy densities without deformation. After structural assembly, units enter an automated shot-blasting booth that guarantees a Sa 2.5 surface profile before a multi-layer epoxy-zinc paint system is applied. The silver-grey finish visible in the close-ups offers exceptional corrosion resistance—equally suitable for coastal, desert, or Arctic deployments.

Layered Quality Control at Every Stage
Quality at TLS is a closed-loop process rather than a final checkpoint. Certified inspectors perform magnetic-particle and ultrasonic weld examinations, while digital callipers confirm critical tolerances to ±0.1 mm. Positive-Material-Identification (PMI) guns verify the alloy composition of stainless-steel hardware, ensuring earthing studs and grounding plates meet international electrical-safety standards. Door gears, lock rods, and gaskets undergo a 1 000-cycle endurance test, and each completed enclosure is pressure-tested to validate IP55 ingress protection before packing.

Safe, Streamlined Global Logistics
Once approved, containers are shrouded in flame-retardant tarpaulins and secured with high-tension diagonal lashings, ready for outbound trucking. GPS-enabled low-bed trailers move units to the nearest sea port, supported by night-shift loading teams to avoid daytime congestion. TLS Energy International handles all export documentation, CSC plate validation, and sea-fastening calculations, so your BESS fleet can sail anywhere—on schedule and fully insured.

Custom-Engineered for Your Project
From 20-ft air-cooled enclosures for behind-the-meter storage to 40-ft liquid-cooled megawatt blocks, our engineers tailor floor layouts, HVAC sizing, fire-suppression routing, and communication penetrations to your exact specifications. We can supply cabinet-grade finishes for data-centre environments or rugged offshore coatings for harsh marine climates. Optional factory-acceptance testing includes charge-discharge cycling, thermal-runaway simulations, and full high-voltage functional checks, giving stakeholders total confidence before site delivery.
