CNG Service Station Repair

Midwest Energy Solutions is building a team of Service Technicians with tools, parts supply and CNG service vans to perform all of the periodic inspection, certification, preventive and repair maintenance to keep components in the best possible operating condition.  We provide systematic inspection, detection, and correction of incipient failures either before they occur or before they develop into major defects and we keep the equipment calibrated to consistently deliver the lowest-cost fuel possible.

To optimize results and minimize costs, MWES typically has the fleet operator / site owner perform day-to-day checks of oil level, storage pressure and other minor tasks.  However, we will also provide complete operations services where the customer wants nothing to do with the station equipment.

Depending on station size, utilization and component make-up, MWES provides weekly and bi-monthly site visits that typically last ~ 8-16 hours per visit.  We also provide compressor and valve overhaul and rebuild services, drier desiccant replacement and disposal throughout the life of each component.

MWES provides the skilled labor, Technicians, hired trade specialists, tools and consumables to complete the contracted preventive maintenance and repair services. MWES's preventive maintenance is designed for the specific equipment at each CNG station site. The following is a summary of some of the maintenance tasks MWES is providing as part of an all-inclusive maintenance at a customer-owned CNG station:
