DriPrime CD150M Critically Silenced, GL5 Highway Trailer 90 USG fuel tank

Sound Attenuated

When the job calls for minimal noise in areas such as residential zones, hospitals or commercial areas, it’s critical to have access to the proper sound attenuated equipment. Aquatech provides a number of options depending on the project specifications.


Critically Silenced

Aquatech’s line-up of critically silenced pumps are fully adaptable to all Dri-Prime range, HL range pumps and Heidra hydraulic diesel packs. They’re constructed of 14 gauge sheet metal lined with 1” (25mm) and 2” (50mm) layers of polydamp acoustical sound deadening material to ensure excellent results, as engine noise is limited to 69dBA at 30 feet (9 metres). The diesel engines are designed with a critical grade silenced muffler, silenced priming exhaust utilizing isolated engine vibration to minimize operating noise. Other features include hinged, lockable doors for easy access to controls and service locations, while the entire skid-mounted pump and enclosure can readily be unbolted and removed from the DOT highway trailer.
