CONTROL SYSTEM: A fully
programmable logic microprocessor
with non-volatile 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
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.
complete cabinet is UL and C-UL listed.
**C-UL is Underwriters Laboratories Safety Certification Mark which indicates that UL has tested the equipment to applicable CSA Standards.
