OCH Air Cooled Oil Coolers

With over 50 years’ experience designing and manufacturing fluid cooling equipment C.H. Bull has created OCH Air Cooled Oil Coolers as an industry standard. Within the fluid power market, many leading industries require an economic custom cooling solution. The custom cooling solutions must be universally adaptable to an increasing variety of air cooled systems applications

Premium OCH Air Cooled Oil Coolers

OCH Oil Coolers have an efficient heat transfer core made of steel tubes, aluminum fins and tubular steel manifolds and are designed for cooling lubricating oil and hydraulic fluids in various applications.

OCH Air Cooled Oil Cooler Applications

  • Bearings
  • Reduction gearing
  • Torque converters
  • Marine Transmissions
  • Transformers
  • Internal combustion engines
  • Machine tools
  • Processing equipment

Heavy-Duty Construction

OCH air cooled oil coolers are manufactured with steel tubes in their core construction, instead of the standard copper tubes that are common in the heat exchanger industry. These steel tubes are mechanically expansion bonded to the core’s aluminum fins—no solder is used in core construction for leak-free performance. High pressure round tubes, plates, fins, and I-form fin collars provide outstanding strength and optimum heat transfer solutions.

An automatic induction, high temperature unique heat exchanger method insures a permanent bond and positive tube to manifold contact, eliminating leaks and providing maximum heat exchanger service life.

All OCH oil coolers feature Young Touchstone’s exclusive patented Turbulators inserted in each tube which improves heat transfer solutions by more than 100% by eliminating laminar oil flow.

OCH coolers provide ample custom cooling solutions in areas where water is costly, unavailable or when water circuit piping is undesirable and inconvenient. Air cooled systems also eliminate the necessity for expensive water anti-freeze solutions required to keep water coolants from freezing during the winter. These air cooled systems can do double duty in cold climates by recirculating the waste heat absorbed in the cooling process to heat the surrounding room interior. 

There are six standard OCH Oil Coolers in sizes from 18” x 18” to 36” x 36” and a top thermal capacity of 100 hp 76 kw available in single and three phase configuration. For larger-scale cooling applications, we also offer OCS air cooled oil coolers.
