Manufacturer:
Thermotron
Condition:
For Parts or Not Working. This chamber is in Good cosmetic condition overall, with a few notable blemishes.  Under the side ports, there are streaks of hard water deposits.  The chamber floor and the bottom of the window also have lots of water spots/hard water residue.  The humidity generator has lots of
brown
residue in the reservoir and clear plastic lines (and probably everywhere else as well).  Inside, on a copper pipe, there is lots of green corrosion.
Notes:
This chamber is NOT working properly!  It heats well, but the cooling performance is badly wanting.  The high side compressor seems to not be working very well and we are not sure why.  The top picture in Photo #4 shows
Temperature rising quickly, stopping when it hit the high limit set by the previous user
Temperature rising quickly after we reset the limit as high as it would go (higher than specified, and it hit a warning)
Temperature falling slightly with refrigeration on, then holding steady at the maximum temperature
Cooling slowly with only 1 stage of refrigeration
Cooling more quickly after the Cascade refrigeration was enabled
Under that, you can see a zoomed-out and zoomed-in view from the next morning.  Cooling below ambient was barely possible, and the temperature stalled at -21º just a couple below ambient.  On the way down from high temperature, the cooling system tripped off, with a "Lo Stg Dch Tmp Warn" message, which went away and the cooling recommenced when the temperatures fell back into tolerance.   Interior fans work. The red display on top of the door works.  The interior light works.  We were not able to figure out how to enable the humidity generator, so that was not tested.  The user level is set to 4 (allows all operations except for calibration) and we do not have a password.  We filled the humidity generator reservoir with water hoping to figure out how it worked, and found a small puddle under the chamber the next morning.  No other testing was done. No manuals, cords/cables, or additional items are included if not listed or shown.
