The Hot Aqua Blaster Colorado 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 equipped with a heat
exchanger, the primary side is connected to the engine's cooling system, and the
secondary side to the water tank on the suction side of the high-pressure pump.
The pre-heated water is 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.
