FTS AirJet XE 753 Temperature Cycling System AS-IS Water in Cooling System

Current Stock:

Product Description

Manufacturer: FTS Systems

Model: XE753

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.  The plastic cover on the air pressure gauge may be missing from the unit you receive.  The mains power and air input connections may vary from those shown. Cosmetic appearance may vary slightly from pictured unit(s).

Notes: This unit is NOT working properly.  We suspect there may be water in the cooling system, which may be able to be fixed just by running VERY dry air through (-80ºC freezing rated) for a while, we are not sure.  The cooling does not reach maximum cold temperature, it only gets to about -65 or so degrees.  The heater overshoots badly and can only attain about 200 degrees.  Eventually the airflow gets less and less as (we suspect) the water inside freezes up and chokes off the passage of air, even to the point of stopping airflow output altogether.  The status lights on the controller doesn't light up. No other testing was done. No manuals, cords/cables, or additional items are included if not listed or shown.
