What if hospital consumption increases in future, what are the options?
Ans: 
If a hospital has oxygen consumption of 45 cylinders/day he can take our AS-J model which caters to 58 cylinders/day .If 5 year down the line consumption goes above 58 cylinders/day we can attach a parallel model with any consumption like 19 cylinder/day or 30 cylinders/day or 58 cylinders/day in the present system.
