The SES329 can be stand-alone skid-mounted, packaged in an easy-to-tow cargo trailer, or integrated into a van, straight truck or deckover cargo trailer package.  

  • Skid Mounting
    Built-to-order skid-mounted equipment can normally be built to meet customer footprint and access requirements.  Consult SESCO with special requests.
  • Cargo Trailer Mounting
    All cargo trailers are specifically engineered to accommodate equipment load, weight distribution, to provide optimum towing conditions. Cargo trailer weight capacities (GVRW) range from 4,000 to 16,000 Lbs. SESCO will provide the cargo trailer size and weight capacity options available for the system being quoted.

The gasoline powered compressor requires only a small 120V generator.  A compressor isolated dual skid package controls engine package vibration.
