E-Line 19-Row Stacked Plate Oil Cooler | 13″ x 5.75″ x 2″ OGEN.STP.100 | No Fan Premium Stacked Plate Construction. No Fan. Maximum Flexibility. The Fluidyne E-Line stacked plate coolers are premium units — built to the same standard as other premium coolers on the market and the right choice for lower-pressure fluid applications where stacked plate construction is the ideal fit. These are not economy coolers. They are well-built, well-priced, and engineered to perform. Stacked plate coolers are best suited for transmission fluid, rear end fluid, and power steering — lower-pressure systems where the construction excels and delivers excellent heat rejection in a compact, clean package. Not recommended for high-pressure engine oil applications. Engineered to withstand pressures up to 250 psi. The 19-row is the entry point in the E-Line family — compact at 13″ × 5.75″ × 2″ and well suited for applications where space is at a premium or cooling demand is moderate. No fan is included, making this the right choice when ram air cooling is sufficient or when you’re adding an existing fan setup. -10 AN ORB fittings give you the freedom to customize your inlet and outlet connections as needed. Four mounting holes on the end tanks for easy installation in virtually any orientation.
