Small/medium size mechanical reciprocating compressors suitable for operating with high suction pressures. Suitable for MRUs.
Discover other configurations:
ST Series compressors are compact mechanical units with 3 to 6 cylinders arranged radially.
They are suitable for:
- Applications where medium/high suction pressures are required
- Stations with high hourly dispensing volumes
- Mobile Refueling Units (MRUs)
With their robust construction, water cooling and no direct lubrication in the cylinders, they ensure high performance, long service life and excellent reliability even under severe operating conditions.
