Freezer, Laboratory, High-Performance, Revco®

Features

• Temperature factory-preset at -20° or -30°C
• Capacities from 4.9 to 51.1 cu.ft. (139 to 1447L)
• Icon-based controls and displays
• Large, easy-to-read digital display shows temperature within 1°C
• Graphic thermometer is steady green when temperature is normal, flashes top bar for overtemperature, flashes bulb for undertemperature

Microprocessor Control

• Audible/visual warnings for overtemperature, undertemperature, or power failure
• Key-operated OFF/ON/ALARM ON master switch for setpoint security
• Push-button alarm test
• Remote alarm contacts
• Alarm silence, ringback, and auto reset
• Controller battery backup system

Construction

• Scratch-resistant cold-rolled steel interior and exterior finishes
• High-density, 2 inch thick (5.1cm) CFC-free urethane foam insulation protects against ambient temperature fluctuations
• CFC-free, HFC-blend refrigerant
• Single-door models are hinged on right
• Full-length door handle and key lock
• Doors self-close and lock open at 90°
• Adjustable epoxy-coated wire shelves
• 1 inch (2.5cm) diameter access port with plug on undercounter model

-30°C Freezers

• Automatic defrost and condensate removal
• Sensor automatically initiates defrost cycle on demand, eliminating need for a defrost timer, minimizing frost buildup, and optimizing coil efficiency
• Forced-air circulation improves temperature uniformity, provides faster recovery after door is opened

-20°C Freezers

• Suitable for applications in which slight intermittent coil warming during an automatic defrost cycle is not desired (such as enzyme storage)
• Gravity convection air system for maximum stability without a blower or fan
• Manual defrost

Ordering Alerts: Alarm systems, temperature chart recorders, and power monitors are available separately.

Warranty and Service Offering: Two years, parts and labor (U.S. and Canada only); international warranties may vary

Compliance: UL and CUL listed. CE marked.
