Deepening ESS Liquid-Cooling Filling — Jinyiheng Enables High-Efficiency Mass Production

Under carbon-neutrality targets, ESS products — utility-scale, C&I, and PACK — iterate quickly and demand strict accuracy, efficiency, and stability in liquid-cooling loop filling. With two decades in fluid filling, Jinyiheng focuses on ESS coolant vacuum/metering filling with differentiated equipment, proven processes, and deployments at leading customers.

Two platforms for full-scene ESS filling

Dry filling equipment — SV vacuum pump with dedicated lubricant, isolation tank tolerant of minor residual fluid, designed for new-product mass lines (not repair). Fill rate 10–70 L/min, pressure auto-matched 0.4–5.5 bar, pass rate above 99.9%.

Wet filling equipment — water-ring pump + atmospheric ejector for higher ultimate vacuum, using coolant as lubricant. Tolerates residual coolant in lines and serves both mass production and repair — ideal for PACK and mid/small ESS lifecycle maintenance.

Both platforms use integrated intelligent control, PLC precision, optional MES connectivity for full fill-data traceability, and mobile or fixed installation for containers, cabinets, and battery packs.

Proven with leading ESS manufacturers

Jinyiheng ESS fillers are deployed at Canadian Solar, Jiuxing, CATL, Hyperstrong, Penghui and other lines — standardizing coolant filling and supporting thermal-management reliability. From large stations to C&I systems and PACK production, we keep investing in liquid-cooling filling to help customers cut cost and raise throughput.
