Standard Shell & Tube

Basco Type OP Heat Exchangers
First introduced in 1962, the Basco 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.

Baffle cuts and spacing for each diameter are consistent with best practices. Shells available in Steel and Stainless Steel. Minmum clearances between shell and baffles reduce by-pass and maximize heat transfer.

Basco'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.
