Environmental protection, energy saving, easy installation and low failure rate. The structure is compact, the heat dissipation area is large, and the heat exchange efficiency is high. Long service life and high working pressure. Can be used for system return oil cooling, drain oil cooling and independent circuit cooling. Low operating cost, in case of cooler rupture, it will not cause oil water mixing like a water cooler, causing fatal damage to the hydraulic (lubricating) system. Applicable fluid temperature: 10°C~ 180°C, adaptable ambient temperature: -40°C~ 100c, Manufacturer: LPUHHDA
