Dual-Safe -80°C Chest Freezers

Rapidly freeze samples in a secure environment with Thermo Scientific™ Dual-Safe -80°C Chest Freezers, which feature a redundant cascade refrigeration systems.

Key Features:
Large capacity of over 32 cu. ft., a high cooling capacity and two independent refrigeration systems for critical samples
Four 1.5hp air-cooled (water-cooled optional) compressors for high capacity and maximum reliability
Three modes of operation, including normal and accelerated pulldown, plus long-term storage
Redundant controls in case of controller failure

Control System:
Keyed master power switch for operating security
Independent refrigeration controls selectable for systems “A” and “B”
Adjustable, integrated temperature control
Toggle between display setpoint, actual operating temperature and alarm limits
Independent adjustable cold and warm alarm setpoints with key-activated switch, audible warning and alarm silence button
Power failure alarm with 24-hour battery back-up
Indicator lights for all control and operational functions
Standard 6″ (15.2cm) circular chart recorder for permanent record of cabinet performance
Battery meter for easy check of backup charge

Refrigeration System:
Two cascade systems operate separately or together depending on system loading.
Thermal expansion valve increases refrigeration BTU removal capacity, increases temperature pulldown rate, improves temperature recovery following lid openings and warm product insertion, and automatically reacts to changing ambient temperatures.
Gravity feed evaporator design assures temperature uniformity within chamber interior, enhances refrigerant flow and oil return, and increases overall efficiency.
System includes CFC-free refrigerants.

Cabinet Design:
Freezers uses standard ultra-low temperature inventory racks with boxes
Coved-corner interior design improves refrigeration efficiency and accelerates heat removal from stored product
Laboratory-grade construction includes minimum 5″ (12.7cm) CFC-free foamed-in-place urethane insulation surrounding interior chamber, plus 3″ (8.9cm) insulation in lid.
Fully insulated lid has two cam-action latches which compress against multiseal gasket to protect against frost build-up.
High-density sublids provide additional protection to stored product during lid openings.
Heavy-gauge, reinforced, cold-rolled steel interior chamber has 50% greater thermal efficiency than stainless steel.
Exterior and interior surfaces are finished with high-impact powder coat paint.
Design includes 1″ diameter thru-wall access port with plug.

Recommended for:
Long-term storage of biological and chemical samples.
