  • Generator Servicing and maintenance

    Generator repairs, maintenance and servicing all form an important part of MEMS quality approach in power generation.

    Providing our customer with a superior service, all generators undergo a complete service with any repairs carried out by our highly skilled and experienced team.

    Preventative maintenance is of paramount importance and MEMS has the capability to provide a national bespoke service and maintenance package to suit your required application; whether it’s a prime running machine completing thousands of hours per annum or a standby unit used for support in the event of power failures and emergencies.


Service & Maintenance

  • Bespoke Maintenance Contracts

    The Service Department provides a first class maintenance solution for all you generators installed on site. With over 30 years of experience in power generation solutions, MEMS have some of the industry’s best engineers and technicians experienced in a wide range of generator and control systems. With this expertise we can provide a bespoke maintenance package to suit your required application; whether it is a prime running machine completing thousands of hours per annum, or a standby generator unit used for backup during power failures and emergencies.

    Emergency Call-out Facility

    All our generator service contracts come with full access to our 24/7 Manned Emergency Call-out facility, where you can speak to one of our technicians day or night, 365 days of the year.

    Generator Engine Analysis

    As a supplement to any of our generator service contract we can provide a detailed oil, fuel and coolant analysis, which not only helps to determine a bespoke maintenance regime for standby units, but also highlights any potential engine issues before they become a serious problem.

    MEMS Power Generation provide unrivalled diesel generator hire, equipment and 24/7 support and servicing throughout the UK.
  • Repairs

    MEMS can undertake all aspects of generator repair, ranging from simple fault diagnosis and routine replacement of components, up to and including major engine overhauls and alternator rewinds.

    Drawing on a comprehensive technical database and extensive experience we have the ability to provide cost effective and reliable repair solutions which can be delivered in a time conscious manner to minimise impact on your business.

    Temporary Hire Sets

  • Control Systems

    All MEMS engineers are fully conversant with a wide range of generator control, AMF and synchronising systems from old relay logic boards to the latest micro-processor controlled units, and are well equipped to diagnose and repair any faults encountered.

    Systems Upgrade

    In the event that a control system has become obsolete, MEMS are able to offer cost-effective upgrades; either integrating controls into existing systems or offering a complete re-design to the customers’ specification.

    Loadbank Testing

    In situations where mains failure testing is not feasible or adequate site load cannot be simulated, MEMS offer the facility for Resistive Loadbank Testing.

    This has the advantage of testing a generator to its full operating capacity, and can be effective in proving performance and diagnosing any potential faults before they become a serious problem.

  • Fuel System Testing and Maintenance

    With many fuel systems only used in emergency situations, regular and complete testing is vital to ensure integrity. MEMS can provide a comprehensive maintenance package to cover all aspects of fuel storage, pump transfer and safety systems associated with bulk diesel fuel storage.

    Tank Cleaning & Fuel Polishing

    With all bulk storage systems, fuel will degrade over time due to contamination from various sources. This problem is further exacerbated by the increased levels of bio-diesel found in modern fuels which promote bacterial growth, furring pipes, blocking filter elements and potentially causing serious damage to engine fuel systems. MEMS can offer a cost effective tank cleaning and fuel polishing solution to keep your fuel up to specification, thus eliminating expensive repairs resulting from poor quality fuel.

    Fuel Deliveries

    MEMS operate an extensive tanker and fuel bowser fleet, enabling us to provide diesel to site either as a regular delivery, or as a emergency response within 4 hours of instruction.
