Figure 10: Operating The Expansion Racks - Binder VDL Series Operating Manual

The vacuum expansion racks made of aluminum (also op-
tionally available in stainless steel) allow low-loss heat trans-
fer to the material. The strong tension causes the racks to fit
tightly against the interior wall and their large-surface contact
area ensures rapid and effective heat transfer.
The removable rack holders allow for easy positioning.
You can remove the expansion racks for easy cleaning. Do
not remove them too often in order to prevent wear.
• Pushing the locking lever: The expansion rack is released and can be removed.
• Pulling the locking lever: The expansion rack is pressed against the inner chamber walls.
Remove or insert the vacuum expansion racks only when the chamber is empty and has
cooled down. NO explosive atmosphere must be present. Active extraction (technical ventila-
tion) is mandatory.
Following each new tightening of an expansion rack, check that the lateral parts of the rack fit
closely over their whole surface to the inner chamber wall. This is necessary in order to ensure
the specified temperature exactitude.
Risk of invalid calibration due to modified heat transmission when changing be-
tween aluminum and stainless steel racks.
Undefined heating behavior.
∅ Do NOT change between aluminum and stainless steel racks
∅ Use the supplied expansion racks only.
