The Hot Aqua Blaster Hudson has an industrial, liquid-cooled Kubota diesel
engine, which drives the Aquabar high-pressure pump directly via a close-coupled
reduction gearbox. The diesel engine is cooled by means of a heat exchanger. The
washing water is pre-heated and then heated to the desired final temperature
using a highly efficient high-pressure heating coil. This Waterkracht Ecoboiler
heating system can achieve fuel savings of up to 20%! The series is equipped as
standard with a Waterkracht-Zero pressure regulation system, which ensures that
if the high-pressure trigger is switched off, the pressure is turned off in the
whole unit, from the trigger gun back to the high-pressure pump, so including
the hose. When work resumes, the operating pressure of the system is restored
immediately.
