CHAMBER CONSTRUCTION
The chamber is a custom designed sheet metal package. Exterior metal is Cold Rolled Steel
(CRS) with a powder coat finish for corrosion resistance. The chamber interior is constructed from
304 stainless steel, with all joints seam welded. The chamber face connecting the interior to the
exterior is magnetic stainless steel providing a sealing surface for the magnetic gasketed exterior
door as well as improved corrosion resistance. The control panel housing is constructed from
aluminum with a powder coat finish. The chamber is insulated on all sides with fiberglass
insulation rated at 70
°
C.
SHELF CONSTRUCTION (STANDARD)
The chamber shelves are polished, 304 stainless steel wire formed.
REFRIGERATION SYSTEM
A bi-modal refrigeration system allows for independent heating and cooling. This system is now
used to replace the less sophisticated type of refrigeration system which used heaters to buck
against the refrigeration system and assist in temperature control. The new design allows the
chamber to respond faster and controls the chamber more efficiently at a constant temperature.
CONTROL SYSTEM
The control system is comprised of a single channel, dual output controller. On/off outputs are
used to drive heaters and cooling solenoids.
SAFETIES
The CARON 6000 Series has a triple redundancy safety system. A temperature alarm in the
temperature controller sounds an alarm to alert the end user to the condition. A thermal snap
disk, high limit and a thermal fuse are provided to prevent run-away heating of the unit. The
compressor and blower motors are both protected by thermal overloads. The Condenser fan
motor is impedance protected.
