De ionized is de-ionized. Contact your local water supplier such as culligan or whoever. They can give you the rundown on leasing or buying tanks, etc... Your cleaner will have to have some type of provision for adding external filtration/deioniza

Am I missing something? Get the Laminate Sizes from your suppliers, and make your own Array Files. You might need to include tooling holes for the Fabrication house but they will surely supply you with the information that they need. This way you
