Shell and tube heat exchanger
Basco Type OP API Heat Transfer Inc.

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.
