Vacuum expansion racks

The low-loss heat transfer to the material occurs via the pa-
tented aluminum vacuum expansion racks (also available in
stainless steel as an option). 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 also 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.
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 en-
sure the specified temperature exactitude.
Invalid calibration.
∅ Do NOT change between aluminum and stainless steel racks
 Use the delivered expansion racks only
