First introduced in 1962, the API Heat Transfer OP design has proven to be the preferred TEMA Type AEW shell & tube heat exchanger in the market. The “OP”, or “O-Ring Protected” design features removable tube bundle, nozzle location flexibility, and a unique threaded O-ring retainer that permits removal of the reversing bonnet without disturbing the piping or draining the shellside fluid. Removal of the channel cover permits full inspection and cleaning of the tube side

API Heat Transfer’s Double “O” Ring Seal Protection
Permits the bundle to expand and contract without strain or intermixing of shell and tubeside fluids. O-Rings retain compression and are unaffected by vibration and temperature changes. Telltale holes reveal any leakage.
Special Feature
The unique construction of the Basco OP permits inspection and maintenance of the tubeside without draining the shellside or disturbing the piping.
Typical applications for the Basco Type OP include:
- Compressed air
- Steam or gas turbine oil
- Hydraulic oil
- Lube oil
- Bearing water
- Jacket water
- Gland seal condensers
- Condensate cooling
- Ship board and marine engines
