The Cressier Refinery is the only operating refinery in Switzerland and serves as a cornerstone of Varo Energy, processing a wide variety of oil products.
As its former service provider constantly delivered less-than-adequate parts and service, Varo Energy needed to turn to someone else for a set of solutions that could get the compressor fleet back to its optimal operating status. The company found that with Burckhardt Compression.
Burckhardt’s professionalism, speed and quality services were instrumental in bringing the compressors back to full working order. Burckhardt ensures that all parts and services are done right the first time. That’s why they became our preferred supplier for capital parts engineering and services.

Customer challenges
- Former service provider did not provide adequate service to keep the compressor running smoothly
- When the cylinder liners lost their integrity, no viable solution, other than supplying new liners instead of an efficient retrofit solution was offered by the OEM
- Newly delivered OPM cylinder liners were oval or did not have the exact dimensions nor the correct roughness
- Piston rods did not have the right coating and therefore did not last long, consequently the packing’s lifetime was reduced
