CONTROL

SYSTEM:

A fully program­mable logic microprocessor with non­volatile memory provides a user interface
through a liquid crystal alphanumeric dis­play. All set points are adjustable by one
multi-function interface key pad. The
standard control includes: Fully program­mable ramp soak functions, product and
air temperature Centigrade scale, alarm /
temperature logging, system mode indi­cator heating / cooling, high / low audible
/ visual alarms, real time clock, power fail­ure alarm, sensor failure alarms, service
prompts and user password entry sys­tem. The modular system includes
expansion slots on the control board for
the ability to add at a later date, the option
of RS485 serial communication interface.

CONDITIONING

SYSTEM:

Precision
control provided by the uniform distribu­tion of air through a ceiling plenum. The
plenum delivers conditioned air evenly
through out the chamber providing maxi­mum uniformity and efficiency. A heavy
duty refrigeration system provides rapid
removal of heat caused by door openings
or product load. The system accurately
delivers cooling based on demand and
modulates the system to provide preci­sion control. The system utilizes environ­mentally safe non-toxic CFC free refriger­ant, with air-cooled, hermetically sealed
compressor backed by a 5 year warranty.
The system includes an expansion valve
system to optimize capacity and efficien­cy. Heating is provided by a incoloy tube
heater. The complete cabinet is ULand
C-UL listed.

CONSTRUCTION: Heavy duty double
wall construction. Interior and exterior fin­ish of heavy gauge steel painted with
scratch resistant baked enamel.
Complete cabinet and door are insulated
and sealed with 100% UL Class 1 rigid
polyurethane foam insulation. The
foamed-in-place insulation provides low
heat transfer, improved cabinet perfor­mance and prohibits moisture from
migrating into the cabinet walls.
Hardware includes: Heavy duty self clos­ing door hinges, full length stainless steel
pull handle, full peripheral high tempera­ture door gasket providing a tight seal.
Key lock door and 4” casters for ease of
rolling. Complete perimeter anti-conden­sate door heater wire thermostatically
controlled for energy savings.
