CORKEN VERTICAL LPG COMPRESSORS
The CORKEN liquid transfer-vapor recovery compressor is a vertical single-stage, single-acting reciprocating compressor designed to handle flammable gases like LPG and toxic gases such as ammonia. Vertical compressors are also perfect for emergency evacuation purposes. Compressors are available in both threaded and ANSI flanged connections.
Stationary and trucks applications
Usually CORKEN vertical compressors are used in stationary applications in terminals, for railcars unloading and trucks loading/unloading. Compressors have also an extended crankshaft option for utilization on trucks for loading/ unloading as well as vapor recovery, with PTO and hydraulic drive systems. We can supply bare or mounted compressors with Siemens ex proof motors AOM, ExdIIB+H2T4Gb.
