Turnkey coating line for BESS enclosures and battery pack housings — blasting to Sa2.5, zinc-rich primer, weather-resistant topcoat and matched exhaust treatment in one engineered chain. MUSI Technology builds energy storage container coating lines in Changzhou, China, as complete turnkey lines with line-wide MES monitoring of temperature, humidity, pressure and flow at each station.
Built for 20 ft and 40 ft energy storage containers, battery pack housings and module cases whose coating system is specified for 15 to 25 years of outdoor design durability — a design target set in each project specification, not a warranty.
Battery energy storage system integrators, container fabricators and EV battery enclosure suppliers, where the finished unit sits outdoors unattended for its full service life and is rarely repainted.
Blast room with full floor media recovery and air-wash separator
Primer booth with humidity control for zinc-rich systems
Flash-off and forced-cure zone at 60-80 C
Topcoat booth in a controlled-cleanliness area
Transfer rails or cars between cells, no manual repositioning

Building services up to the battery limit: power supply, gas, compressed air, water and drainage
Local permits, emission approvals and third-party inspections
Paint or powder supply, unless stated in the contract
MUSI Technology supplies, installs and commissions the coating line equipment listed above; the enclosures are then coated by your own plant on that line, so this page describes equipment supply rather than a contract coating service.
What to send for a quotation: part drawings or photos, the largest part size and weight, the material, the required output per shift and cycle time, the coating type (powder, liquid, UV or 2K) and the number of colours, and the available floor space, ceiling height, power or gas supply and local emission requirements.
Every line is engineered against a written performance specification. Line speed, cure profile, film build and emission level are stated in the contract and demonstrated on your own part at the factory trial run before shipment. One engineering team owns the whole chain — pretreatment, application, curing, conveying and emission control — so the trade-offs between them are settled on the drawing board, not on your factory floor.
Service & Delivery
Standard configurations ship in 30-60 days with a 12-month full-machine and 36-month critical-component warranty. On-site installation, commissioning and operator training are available worldwide, and process tuning and spare parts support continue for the working life of the line. Structural parts are covered for up to 60 months.

Q
Questions buyers ask before ordering
quotation · price · lead time · installation · warranty
What information do you need to prepare a quotation?
Send part drawings or photos, the largest part size and weight, the material, the required output per shift, the paint or powder type and number of colours, and the available floor space, ceiling height and power or gas supply. MUSI engineers reply within 24 hours; a recommended configuration and quotation follow once your part data is complete.
How much does this equipment cost?
Budget depends on part size, throughput and the level of automation. Indicative ex-works ranges are published in our complete coating line cost guide; a configured quotation is prepared from your part data. Published indicative ex-works ranges: a complete powder coating line is roughly USD 75,000–230,000 semi-automatic, USD 200,000–600,000 for a standard automatic line and USD 600,000–2,000,000 for a high-throughput automated plant.
What is the lead time?
Standard configurations ship in 30–60 days from contract signing and down payment; custom configurations take longer. The delivery date is fixed in the contract.
Do you install and train operators overseas?
Yes. MUSI engineers carry out on-site installation and commissioning and give 3–5 days of operator and maintenance training. MUSI has delivered 800+ coating lines to customers in 36 countries.
What warranty and after-sales support are included?
12 months full-machine warranty, 36 months on critical components and up to 60 months on structural parts. International customers get 24-hour phone response and 72-hour on-site arrival; spare parts ship from the Changzhou headquarters.
Can the environmental equipment be supplied with the line?
Yes. VOC treatment (RTO, RCO, activated carbon, zeolite rotor), dust collection and paint wastewater treatment are supplied with the coating line under one contract; MUSI has equipped 50+ coating facilities whose projects all passed local environmental compliance reviews.
Manufacturer: MUSI Technology (Changzhou MUSI Environmental Technology Co., Ltd.), Changzhou, China. MUSI designs, builds and installs this equipment as a single unit or as part of a turnkey coating line.
