About DXG
The DXG series consists of heavy-duty, air-cooled oil coolers designed for high heat dissipation. Featuring an upgraded, enlarged heat exchange core and increased convective cooling surface area, these units deliver significantly improved heat exchange efficiency. Capable of withstanding continuous, uninterrupted operation and high-heat, high-temperature-rise conditions over extended periods, they provide stable and long-lasting temperature control. These coolers are ideal for high-load, long-duration applications such as heavy-duty forming equipment, multi-unit systems, and hydraulic systems supporting production lines.
