Vestergaard Company's E-ZVTS is a gasoline-electrically driven vacuum toilet service unit containing all the valued features of the ZVTS, such as the vacuum system, fast and high performing operations and with a very high level of safety for both aircraft and ground crew. The E-ZVTS creates less airborne particles in the congested gate environment and no exhaust filter regeneration. The gasoline-powered chassis drives a generator, which in turn drives all functions on the E-ZVTS. As there are no hydraulic pump, pressure or hoses, the unit has minimal maintenance. Designed for warmer climates, the E-ZVTS can be fitted on different standard truck chassis to fit various operations.
