Thermotron FM-16-CHM-5-5 Environmental Chamber 480V

Manufacturer: Thermotron

Model: FM-16-CHM-5-5

Condition: Used. This chamber is well worn with a few fasteners absent or mangled.  It has been repainted and is a bit of an ugly duckling, but lovable nonetheless for its cooling capacity and ramp rate.  It's very well constructed. The photos show the exact item(s) the buyer will receive.

Notes: We ran this chamber; it achieved -25C from 20C in five minutes; a further seven minutes resulted in -50C.  Nine minutes were required to reach -60C from -50C.  The heater works; it draws 6A at 480V three-phase.  The steam generator shows good continuity.  The humidity sensor does not work and the humidity coil did not energize when we enabled humidity in the control.  The humidity water fill does work.  A tag by the data plate states a refrigerant conversion was performed in 1995 from R13/R502 to R23/R404A.  At this time a refrigerant expansion tank was added at the top of the chamber.  Apparently, the 4800 control is original to this unit; it has several option cards including GPIB.  The chart recorder is a Truline by Honeywell; it seems to work but we did not have paper to test it with.  A Destaco latch was installed to remedy a door leak.  No manual or shelves are included.

A refrigeration tech will be required to install this unit as the R404A compressor runs periodically to keep liquid refrigerant out of the suction line.  R404A leakdown is very slow.  

This is a nice high powered chamber ready to work.  An oldie but a goodie.   No manuals, cords/cables, or additional items are included if not listed or shown.
