Your Premier Chiller Manufacturer and Supplier in China Over 20 Years
The ACOS Series Immersion Oil Chiller is a compact and highly efficient direct-immersion process cooling system engineered for open-tank oil temperature management. Designed with a custom-engineered drop-in cooling coil, the ACOS series is installed directly into existing hydraulic oil reservoirs, coolant tanks, or machine tool sumps—eliminating the need for external oil pumps and complex piping. By offering precise oil temperature control, zero risk of external oil leakage, and a minimal factory footprint, the ACOS series ensures maximum operational reliability and thermal stability for machine tools, hydraulic units, and heavy industrial machinery.
The ACOS Series is specifically engineered for direct-tank immersion cooling across various industrial machining and power applications:
