The Heavy-Duty Air-Cooled Industrial Oil Cooler is a professional cooling equipment dedicated to hydraulic oil, lubricating oil and thermal oil cooling of heavy machinery, adopting air-cooled heat exchange technology and a heavy-duty structural design to adapt to the harsh working conditions of construction, metallurgy and mining industries. This machinery-specific air-cooled oil cooler features imported hermetic rotor/scroll compressors, corrosion-resistant evaporators and a high-pressure oil pump system, with a cooling capacity ranging from 2.9kW to 180kW and precise oil temperature control (15℃/10℃ inlet/outlet). As a core B2B equipment for heavy machinery normal operation, the corrosion-resistant industrial oil cooler solves the problem of oil overheating in continuous high-load operation of machinery, extending the service life of hydraulic systems and reducing maintenance costs. Its outdoor-friendly design, complete safety protection and multiple customization options make it the first choice for oil cooling of construction machinery, mining equipment and industrial heavy-duty lathes.
High-strength welded steel frame with thickened metal plates and anti-vibration compressor mounting, resistant to strong vibration and impact during machinery operation (e.g., construction cranes, mining excavators).
Optional acid-alkali resistant evaporator and oil pipelines, suitable for cooling various industrial oils (hydraulic oil, lubricating oil, thermal oil) with different chemical properties; no oil leakage and easy cleaning.
Adopts MCHE or finned tube condenser with large air flow (1000~60000 m³/h), fast heat dissipation and no need for cooling water, adapting to water-scarce construction sites and open-air mining areas.
Equipped with a high-performance oil pump with pressure ranging from 2.0bar to 2.7bar and flow from 0.5m³/h to 31m³/h, ensuring sufficient oil circulation for heavy machinery cooling.
European/Japanese imported compressors, Danfoss/Sporlan/Carel refrigeration valves and ABB/SIEMENS/Schneider electrical components, with a mean time between failures (MTBF) of more than 8000 hours.
