More new and exciting projects recently completed by the Optimum team included a dry ice clean down of a casting vacuum unit.
Whilst the blast itself was rather straight forward, the dust control was anything but! If anyone reading this works with a Consarc 350 casting unit, or has blasted one, then you will know exactly what I’m talking about.
The internal machine surface becomes covered in a carbon deposit that has to be removed as it effects product quality after a period of time. The removal process sends the carbon airborne and, as we are working in a confined space, reduces visibility to virtually zero. We use powerful vents to push air in at one end, and filtration/dust control to extract (as much as we can) at the other end.
The problem when working inside a tank is that the nature of our blast guns means the air vortexes around, and with it the dust. To create a safe working environment for the teams these were the processes put in place:
The process was safe and controlled and the customer was very pleased with the quality of the clean and also the time taken to complete.
We have now been asked to quote for the remaining 4 machines at the site and have been included on a monthly cleaning schedule.
All in all a very successful blast and I’d like to thank the crews involved for their professionalism, input and hard work.
