Revco -20°C
Enzyme and
Laboratory
Freezers
Featuring IntrLogic
Microprocessor
Control
Our manual defrost -20°C
upright freezers are designed for
storage applications where
slight intermittent coil warming
during an auto defrost cycle is
not desired. Two models feature
gravity convection air systems
for maximum stability without
blowers or fans.
The -20°C UEN-2320 enzyme freezer
stores 45 enzyme bins on 9 shelves.
Shown with optional casters and
temperature recorder.
Our -20°C freezers feature the
IntrLogic microprocessor control
system, gravity air circulation,
industrial quality cabinet
construction, and extra-strength
refrigeration compressors selected
for industrial, clinical and scientific
use.
The UEN-2320 enzyme freezer
features an easily accessible
inventory system, while the UGL2320 general lab freezer offers
flexible utility value with four-wire
shelves.
IntrLogic Microprocessor Control
Our -20°C enzyme and laboratory
freezers feature enhanced digital
electronic technology designed to
simplify operation and deliver greater
accuracy (see pages 4 and 5).
• Pre-set -20°C operation
• Icon-based controls and displays
include graphic references for
universal operation
• Setpoint security with keyoperated triple-position master
switch controls power to
all systems for added safety

• Audible/visual warnings for overtemperature, undertemperature
and power failure, with visual
status reports on critical functions
• Graphic thermometer confirms
proper operation at-a-glance,
shows normal, high or low
temperature condition; steady
green for normal, flashing top bar
for overtemperature, flashing bulb
for undertemperature
• Enlarged digital display,
resolution to within 0.1°C,
improves visibility
• Alarm silence, ringback and
automatic reset functions
• Push button alarm test verifies
sensor continuity
• Battery backup assures control
panel function during power
failure
• Remote alarm contacts are
standard on
all models
High impact plastic enzyme
storage bins enable easily
accessible, highly concentrated
inventory storage. Additional
bins are useful for managing
loose material in general
purpose applications; see
Accessories section.

Visual Alarm
Audible and visual warnings for door ajar, low alarm battery, system maintenance and power failure provide immediate status of critical functions. A push-button alarm test
verifies sensor continuity, while the battery backup assures system readiness. The enlarged digital display improves visibility, taking the guesswork out of setpoint and
performance management.
*Mute will silence audible alarm with 6-minute ring back interval; display remains flashing. Moving triple position key switch to middle position disables alarm and audible
and visual warnings.
