Vortech - Low-pressure, swirling vortex cleaning equipment
Where has it been used?

A modular approach to design
The VorTech systems comprise four parts: The air cooler, to cool the incoming pressurised supply.
The pressure pot, which serves as the reservoir for the granulate abrasive. The air powered water pump, which pumps a medium pressure supply of water to the nozzle and the hose set, to deliver the pressurised abrasive mixture to the area being cleaned.
A standard hose set is of 20m length, which ordinarily provides enough range from the pressure pot for most sites, whilst being short enough to pack away and transport more easily. The hoses are set up in such a way as to provide instantaneous start up and shut down, which sets us apart from the 3-5 second delay exhibited by earlier Jos-type systems.
Air powered water pump
The water pump can be fed from a standard hosepipe, or draw its own supply from a static water source. It hangs on the pressure pot and performs two main functions. Firstly to combine with the air/abrasive mixture, which minimises dust production and flushes the surface pores of the substrate whilst cleaning. Secondly, via a separate wash down nozzle, the freshly cleaned area can be rinsed free of debris.
Air cooler / after cooler
The air cooler is provided to cool and dehumidify the incoming air from the compressor. It has an automatic water trap, which will periodically dump water condensed in the cooler. The amount of water released is dependent on atmospheric conditions daily.
