....the proven way to maximize operating
life of large reciprocating compressors
 The
BDC-OF12H is a rugged, process gas, reciprocating compressor
designed conservatively in accordance with API-618 for maximum longevity.
It is available in two, four, and six throws and can be used for multiple
applications. This machine has been designed for maximum reliability and
ease of maintenance.
