|
#12 |
|
This project required a custom temperature monitoring setup, which was crucial to the project success. |
|
|
|
|
|
|
|
|
|
|
|
#13 |
|
Precise combination of Time and Temperature are both critical factors in achieving a 100% solid and workable Polybutene Oil Freeze Plug.
|
|
|
|
|
|
|
|
|
|
|
#14 |
|
Freeze plug frost band lengths are recorded as well as all other pertinent CRYO-LATOR™ operational notes, thermocouple temperatures and liquid nitrogen volumes.
|
