Compare the quoted supply mode and charges
Air Liquide lists packaged, bulk, onsite and pipeline supply modes for industrial gases. If the proposed supply uses cylinders, ask what record shows the containers delivered and returned and how an outstanding container affects the bill.
Nippon Sanso describes selected cylinder, bulk and pipeline formats on its Singapore gas solutions page.
Start by asking your site specialist for the approved gas specification for your application. Then ask each supplier which supply mode they offer for that specification. Compare cylinder or equipment responsibility, minimum order and delivery charges, the return process, all written documents and any renewal conditions. Ask for these terms in the written quote.
Choose by what you need
