Industrial Air Cooled T-Bar Extruded Tube Brazed Aluminum

The OCA Series is our high-performance series for high heat rejection, rough environment, and high viscosity fluids. OCA units are available in a wide range of sizes designed for a broad range of both mobile and industrial applications.  Its rugged steel construction features the patented T-BAR solid extrusion core technology but is more efficient and lighter in weight than competitor models.  This high performing series has the ability to handle high viscosity fluids with the advantage of providing ample cooling in areas where water is costly or unavailable.

Consult catalog for additional sizes and technical information.
