Type OP (TEMA AEW or BEW)
Basco™® Type OP Shell & Tube Heat Exchangers
First introduced in 1962, our Basco™ OP design has proven to be the preferred TEMA Type AEW shell and tube heat exchanger in the market. The "OP", or "O-Ring Protected" design features a 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.
Our Basco™® 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.
