Cosmetic appearance may vary slightly from pictured unit(s).
Manufacturer:
FTS Systems
Condition:
For Parts or Not Working. This system is in Fair cosmetic condition.  There are lots of small scuffs/scratches/dings especially in the bigger cabinet that make it look a little rough from close up.  Note that the air and mains power input connections may vary from those shown in photos.
Notes:
This unit is in mostly-working condition.  It gets cold and hot, but the temperature transitions are longer than specified by the manufacturer.  Heating times are about the right duration at low temperature, but cooling times are slow, up to double the rated 20 seconds from +125 to -55 Also note: this unit overshot so far it set off the Overtemperature safety limit and the maximum temperature we were able to get was about 180 degrees.  Stability at setpoint is not to specification, bouncing around + and - several degrees.  This may be as simple to fix as re-tuning the PID values in the controller, but we are not sure.  The refrigeration status light may not illuminate on the unit you receive but refrigeration still works. No other testing was done. No manuals, cords/cables, or additional items are included if not listed or shown.
Included:
(1) Refrigeration Unit with Output Hose attached
(1) Controller
(1) Connection Cable
