Thomassen C-Series of API618 Reciprocating Compressors
The Howden C-Series are the Heavy Duty API618 Thomassen Reciprocating Compressors. Tailor made designs are always made to assure flexible fit for process and applications.
Key Benefits
The Thomassen C-series covers a range from one to 33MW and meet all of the relevant API 618 and ISO specifications. The design has been optimised for easy access to facilitate maintenance and minimise downtime. The cylinders are horizontally opposed and balanced to ensure long-term vibration-free running.
More information can be found in the compressor brochure.
Standard Features
FFPTM Free Floating Piston removes rider ring wear at a stroke in non-lubricated systems by using a cushion of pressurised process gas to float the piston.
Hydrofit Couplings are located at both the piston and the crosshead ends to offset against fatigue failure at the most critical points
Optional Features
The RsensTM system places a sensor inside the piston head cover itself, from where it provides precise and reliable feedback of rider ring condition.
