This cabinet holds 4 products, SP Degeaser, Acid Copper, Bright Nickel, and Copy chrome. Each insulated tank is 4.5 Gal capacity. Storage for related chemicals, parts, and supplies below. Wired through and next to the rectifier is a switch panel to energize the connections for 6 functions, acid copper - tank, nickel - tank, copy chrome - tank, copper - brush, nickel - brush, and optional brush or tank. I am building an enclosure to move the guts of the rectifier, the switching function for the rectifier, snd a set of toggle switches with indicator lights for all other functions such as vent fan, pumps, heaters, recycle water pump and master on/off. This, the 3rd of three cabinets are all on wheels for portability.
