MEHRER Compression GmbH is a German manufacturer with over 135 years of experience, specialised in 100% oil-free compression for process gases and energy applications. Its installed base is concentrated in services where safety, gas purity and high availability are non-negotiable requirements. In industrial compression, the core of its offering is based on dry-running oil-free reciprocating piston compressors, with no oil in the compression chamber, configurable in V or vertical designs and oriented towards demanding applications in general industry, chemical and energy sectors.
In terms of capacity, MEHRER offers oil-free solutions with discharge pressures of up to 220 bar, focused on process gas recompression, gas recovery and recycling, available in air-cooled or water-cooled versions depending on the service and operating conditions. This flexibility allows the equipment to be adapted to the actual operating point and criticality of each installation, maintaining high mechanical reliability and operational stability.
The company is particularly distinguished in CO₂, with solutions for recovery and reutilisation, including wet or aggressive CO₂ compression and services associated with fermentation or gas systems, where purity and process stability are priorities. In hydrogen, its approach targets high-pressure solutions for H₂ infrastructure, including refuelling stations and various supply schemes. This is complemented by declared experience in specialty gases such as argon, helium and nitrogen, as well as other industrial and process gases.
In biogas and biomethane, MEHRER provides modular and compact solutions for gas boosting, treated biomethane injection to grid, raw biogas purification and processing, leak gas recompression and Power-to-Gas schemes. Its project philosophy allows supplying the equipment as a bare unit, packaged unit or complete system from a single source, reducing interfaces, accelerating installation and facilitating spare parts and service standardisation. Furthermore, compressors can be supplied suitable for potentially explosive atmospheres (Ex zones 1 and 2).
Overall, working with MEHRER means having a clean, robust and adaptable compression solution, particularly valuable when the process demands oil-free gas and maximum operational safety.
