Diesel fuelled water-cooled generating set UMM-20

Generating set UMM-20, mobile version

  • UMM-20 by MERIDIAN® could be used as a prime, standby or emergency power source at drilling platforms, surface mines, building sites, offshore platforms, rural areas and many other places and areas.
  • Great version choices – select stationary or mobile version, open set or canopied set, simple or sound attenuated enclosure.
  • The asynchronous brushless generator has no brushes, rings or rotating windings on the rotor, that results to the exceptional reliability while working under the very extreme operating conditions.
  • Rated for the conditions of the moderate climate with the ambient air temperature –49°F (–45°С) to 113°F (+45°С) at altitude up to 1000 m and the relative humidity of air up to 80% at a temperature of 68°F (20°С).
  • Every generating set comes factory tested. The warranty period is twelve months.
