GENERAL

HWP High Pressure Dust Suppression system forms microscopic water 

mist which means low water consumption and low costs. Mist-like 

atomized water binds even the smallest dust particles and makes them 

heavier to falling down in a controlled manner. Dust suppression system 

avoid soiling of surroundings, inhibits mud sagging keeping the working 

area almost dry.  

The compact hydraulic operated high pressure pump is easily mounted 

onto the machine. 

HPW pump is controlled by electric ON/OFF valve on machinery cabin. 

Hydraulic valve kit controls the water pressure with pressure reducer 

and the oil flow limiter. Pressure reducer and solenoid valve to 

appropriate application control nozzles water flow. Pressure compensated 

oil flow-limiter controls the biggest running speed of the HPW-pump.  

Excavator fitted Dynaset HPW-Dust suppression system are dual power 

stage type. Continuous basic dust suppression is supplement with a 

high power mode, which is used as frequently as necessary to suppress 

dust created during demolition by fallen debris by bulk-loaded dump on 

a truck’s platform etc. 

Technically dual stage power output is implemented in two different 

ways:

1. In a 

Dual Water Circuit (DWC)

, both basic and high power 

    levels use individual high-pressure nozzle pairs. The high power  

    dust suppression is switched on by activating separate water 

    solenoid valve. 

    High power suppression nozzles can be the first time coarsely       

    pre-aimed to an assumed dust source according to task demand  

    and conditions. Exact aiming is done after the experiment.    

2. In a 

Single

 

Water Circuit (SWC)

, the same nozzle pair is for 

    both basic and high power dust suppression, using two separate  

    hydraulic flows – one for each power level of dust suppression. 

Prior to switching on the dust suppression, operator have to aim the 

attachment with dust suppression nozzles to a dust source. 

Front loader’s bucket or mobile crusher’s feed hopper and conveyors 

can be equipped with dust suppression-nozzle pipe(s) of a single 

water circuit mode continuous mode, dust suppression system 

HPW200 Dust.
