Setrab Engine Oil Coolers: Motorsport-Proven Thermal Management

When engine oil temperatures climb under sustained hard driving, racing, or towing, an effective engine oil cooler is one of the most critical components protecting your engine's internals. Setrab Oil Coolers has spent decades engineering stacked-plate engine oil coolers that are trusted not only by grassroots racers but by OEM-level manufacturers — a pedigree that speaks directly to their engineering depth and build quality.

The ProLine System: Built Around a Better Connection

At the heart of Setrab's engine oil cooler lineup is the ProLine system, developed to introduce — for the first time in a stacked-plate air-to-oil heat exchanger — a proprietary female port design. The M22 "ProLine" port is a low-profile 22mm x 1.5 flat-faced female port that is adaptable to virtually any hose size through ProLine Adapter Fittings, making installation flexible across a huge range of builds and applications.

Within the ProLine family, Setrab offers several distinct engine oil cooler series to meet different space and performance requirements:

• ProLine STD: The flagship stacked-plate range, offering multiple height and width combinations. The stacked-plate design coupled with state-of-the-art brazing technology creates a durable, highly efficient cooler that is often imitated but never replicated.
• ProLine SLM: Developed for demanding applications where underhood space is at a premium. The SLM series is over 20% thinner than the ProLine STD range while retaining end-tank ports and threaded mounting bosses for a secure, compact fitment.
• ProLine COM: Engineered for heavy-duty, high-performance builds that require versatile plumbing options. The COM design allows for a wider cooler body with heavier end tanks, suited to extreme-duty engine cooling circuits.
• ProLine Specialty: Designed for high-GPM dry-sump racing applications, these coolers alter the standard flow path — including a diagonal-flow option — to optimize heat rejection in specialized oiling systems where maximum flow-through is essential.

What Sets Setrab Apart: Brazing, Turbulators, and Fins

Setrab's manufacturing philosophy goes far beyond simply assembling aluminum plates. The company has been at the forefront of brazing research and development for generations — treating the brazing step not just as a construction method but as a performance variable in itself. This approach results in fully brazed joints with virtually zero heat-transfer barrier throughout the cooler.

Setrab engine oil coolers also employ an in-line turbulator design that gently agitates the oil passing through the cooler, ensuring full exposure to the cooler's entire internal surface area with minimal pressure drop. The turbulators are fully brazed to the entire internal length of each tube. Fins are manufactured in-house to precise tolerances and include mini-louvers on each fin section to maximize the effectiveness of airflow across the cooler's face.

Each cooler is factory pressure tested to 10 bar (145 psi), confirming structural integrity before it ever leaves the factory. Setrab also employs precise tooling in more sizes than any competing manufacturer, enabling more height-and-width combinations than the competition — an advantage that makes it straightforward to find the right cooler for nearly any engine bay.
