The Apsco SS934 ThermaFlow Series is a line of heavy-duty hydraulic oil cooling systems designed for dump trucks, mobile hydraulic equipment, PTO-driven systems, and severe-duty vocational applications. Built around the APSCO “934” cooler platform, the SS934 series combines high-capacity heat exchangers, integrated fan systems, and optional directional control or relief valve configurations to help maintain proper hydraulic oil temperatures during continuous-duty operation.
Excessive heat in your equipment’s hydraulic system reduces the efficiency of your system and the life of your hydraulic oil, resulting in lower power and higher operating costs. The SS934 space efficient solution provides superior heat rejection, lowering the overall cost of ownership of your equipment.
