DURABLE AND PORTABLE POWER THAT’S TOUGH, YET QUIET.
MMD Equipment’s PowerPro™ towable generators are engineered to handle the most rugged requirements for temporary jobsite power, with Delta Demand Excitation™ technology that responds immediately under variable loads. Plus, Quietech™ sound reduction makes them quiet enough to provide power for that all-important special event. Mobile, dependable and easy to operate, PowerPro towable generators are the right choice for all of your light-duty and medium-duty temporary power needs.

QUIETECH™ SOUND REDUCTION

• Frame and cabinet are built with high-strength materials, and all doors and movable fixtures are engineered to minimize vibration.
• The cabinet is designed as an acoustical chamber optimized to reduce sound power. Cabinet interior is lined with a special vibrationabsorbent, open-cell polymer material to cancel acoustic vibrations. This oil- and soil-resistant material is bonded to the cabinet walls with a resilient adhesive that enhances its performance.
• The unit’s airflow has been engineered to provide proper cooling at an absolute minimum noise level.
• Engine combustion chambers have been shaped to minimize or eliminate diesel clatter. Direct-injection fuel delivery is quieter and easier to maintain. Oversized muffler results in a quiet exhaust.

DELTA DEMAND EXCITATION™

• Automatically adjusts voltage output instantly when variable loads are applied to the generator.
• System is composed of three interlinked elements: a solid state automatic voltage regulator (AVR) that monitors the power output of the machine; an independent power coil that supplies excitation energy; and an excitation coil that induces the generator primary coil to produce more voltage to meet demand.
• Produces entertainment industry-grade power when combined with optional electronic governor.

CURBSIDE POWER CONNECTIONS

• Direct connections are labeled in standard U.S. nomenclature (L1, L2, L3, N) and are guarded by a clear cover that has test meter probe access to each terminal even when the guard is closed, allowing safer setup and testing for all applications.
• GFCI convenience and 50 amp twist lock connections are protected with a guard that is secured for safety during operation, yet allows easy
  access to connections during setup.
• All power connections are curbside for convenience and safety in urban applications.

LOCKABLE CONTROL PANEL

• Warning lights and analog gauges including fuel, tachometer, oil pressure, coolant temperature and charging system amps provide easy monitoring
  of engine operations.
• Generator output is controlled by a lockable voltage changeover switch and is monitored by analog gauges measuring volts, amps and frequency.
• Current selector switch, voltage adjuster and main circuit breaker are all protected behind a lockable
  door. For added safety, the Emergency Stop button is located below the door for accessibility at all times.
• Panel light has an on-off switch.

AUTOSTART

• Airman autostart control provides an easy connection to transfer switch applications and delivers instant backup power to a building’s electrical system.
• Provides automatic glowplug delay and overcrank protection.

RELIABLE ENGINES

• Units feature either Nissan or Isuzu diesel engines that are
  EPA Tier 2 compliant and meet CARB certification.
• Electric Fuel Primer and Air-Bleed (EFPA) Pump automatically
  bleeds air from the system without opening the injector lines
  if the generator runs out of fuel — reducing downtime and
  maintenance calls.
• Automatic protection from low oil pressure and high
  temperature conditions.
• Restriction indicator eliminates guesswork about when to
  change the air filter.
• Starting and battery charging systems are either 12 or 24
  volts, depending on model.

COMPACT, DURABLE DESIGN

• PowerPro machines are compact, yet offer unrestricted access to service components.
• All engine fluids drain to the outside of the machine.
• Cabinets are powder-coated, and all hardware is stainless steel to maintain a fresh look for years. All cabinet doors lock with a key.
• Off-white cabinet finish minimizes visibility impact in entertainment applications.

TRAILERS

• Trailers are available with single or tandem axles, and surge or electric brakes to best fit your needs.
• Trailer-mounted and skid-application fuel tanks are both filled through a locking fuel door on the generator cabinet.

Generator accessories available as an MMD option on all models: Electronic Governor Control, Battery Charger, Camlock Connectors and Engine Block Heater.
