PROJECT TARGET
CHECK/ACT
Memmert UF450 oven needed replacement due to damages under operation. A new, larger
Memmert UF750 oven serves as the replacement. Capacity is limited to the qualified mass and
volume of former oven as per the Memmert UF750 QTR (3/23/2015) and must be re-qualified
for increased capacities to operate efficiently. Increased capacities reduce the number of bakes
per day, minimizing risk to oxygen fill room employees as well as preparing for future growth of
production.
• Qualify Memmert UF750 oven to support production capacity of 77 4441785-034 oxygen cylinders.
At 3831.5 ci and 91.630 kg such that will support
o 77 (3”, 3.25” diameter) cylinders
o 119 (2” diameter) cylinders
o 147 (1.5” diameter) cylinders.
• Save process time by 140 minutes/Day
•Reduce to 1 oven cycle per day
• Create Oven Fill Calculator to insure qualification capacities.
