Oil ways are interspaced with airway corrugations providing optimum heat transfer, while the oil passages use "turbulators" to break down boundary layer effects in the oil flow. Setrab Oil Coolers employ an in line turbulator to gently stir the fluid being cooled, thereby ensuring that the fluid has exposure to the entire internal surface
