CONTROL SYSTEM: Afully program-
mable logic microprocessor with non-
volatile memory provides a user interface
through a liquid crystal alphanumeric dis-
play. All set points are adjustable by one
multi-function interface key pad. The
standard control includes: Fully program-
mable ramp soak functions, product and
air temperature Centigrade scale, alarm /
temperature logging, system mode indi-
cator heating / cooling, high / low audible
/ visual alarms, real time clock, power fail-
ure alarm, sensor failure alarms, service
prompts and user password entry sys-
tem. 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 distribu-
tion of air through a ceiling plenum. The
plenum delivers conditioned air evenly
through out the chamber providing maxi-
mum 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 preci-
sion control. The system utilizes environ-
mentally safe non-toxic CFC free refriger-
ant, with air-cooled, hermetically sealed
compressor backed by a 5 year warranty.
The system includes an expansion valve
system to optimize capacity and efficien-
cy. Heating is provided by a incoloy tube
heater. The complete cabinet is UL and
C-UL listed.
CONSTRUCTION: Heavy duty double
wall construction. Interior and exterior fin-
ish 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 perfor-
mance and prohibits moisture from
migrating into the cabinet walls.
Hardware includes: Heavy duty self clos-
ing door hinges, full length stainless steel
pull handle, full peripheral high tempera-
ture door gasket providing a tight seal.
Key lock door and 4” casters for ease of
rolling. Complete perimeter anti-conden-
sate door heater wire thermostatically
controlled for energy savings.

Typical Temperature / Humidity Operation
Humidification / Dehumidification:
Relative humidity is induced by a highly efficient
centrifugal atomizer with a sealed motor and
low maintenance reservoir. Dehumidification is
achieved by the use of a separate dehumidifi-
cation latent coil. Both systems are precisely
controlled by the programmable logic
microprocessor. The humidity controller utilizes
a dry capacitance type sensor for rapid
response to humidity changes with exceptional
accuracy. The humidifier requires a water
source with low mineral content; i.e., resistance
of 0.5 - 1.0 megohm and a pressure of 10 - 100
psi. Reverse osmosis treated water is
recommended. The water supply connection
requires 1/4” plastic or copper tubing.
Performance:
Temperature Variation: +/-0.5°C @ 4°C to 70°C. The
published temperature variation is derived from the
maximum deviation of the thermocouple located near-
est the chamber geometric center during the entire
test period. (i.e. 25.0°C min and 26.0°C max divided
by two would be a variation of +/-0.5°C).
Temperature Uniformity:
+/-1°C @ 4°C to 70°C. The published temperature
uniformity is derived from the maximum deviation of 9
thermocouples are placed on 3 horizontal planes,
each plane having the thermocouples evenly spaced
diagonally across the shelf from the left and right inner
wall, and the middle sensor placed in the approximate
geometric center of the shelf.
Humidity Variation:
+/-5% @ 5°C to 60°C and RH within performance
graph. Humidity variation is derived from the maxi-
mum deviation of the humidity sensor during the test
period.
Performance data is based on
23°C, 50%RH ambient condi-
tions, type T-24 Ga. thermo-
couples with 1.0oz. brass
slugs attached and no product
in the chamber. Data may
vary if; ambient conditions
change, product load is
added, or other changes
cause interference to chamber
airflow.
