High Voltage Power Supply

Re: Upgrading of 800 science laboratories (NSW public schools on
Hi MariaC,
I have the plans for our new labs and they have..CODE "DW" DESCRIPTION "Dish Washer (domestic type) SIZE "TBC". Hope all goes well for you. I also think the new storage system will take a bit of getting use to but at least it will be clean and easy to open!
