23 Cu. Ft. Premium Laboratory Auto Defrost Freezer

Product Number: ABT-HC-PLF-23
ALSO AVAILABLE IN THESE SIZES49 CU. FT.

The ABT-HC-PLF-23 Premium Laboratory Freezer delivers superior cooling performance through advanced variable speed compressor (VSC) technology. This 23 cubic foot unit provides ultra-quiet operation while achieving exceptional temperature uniformity of ±0.7°C and stability of ±1.8°C across the cabinet. With energy consumption of just 8.57 kWh per day, the system optimizes power usage by self-adjusting compressor speeds based on cooling demands.

Engineered for demanding laboratory environments, the ABT-HC-PLF-23 features microprocessor-controlled temperature management with a full array of protective alarms including power failure, sensor failure, and high/low temperature alerts. The unit maintains precise control across an adjustable range of -35°C to -15°C, with rapid pull-down to operating temperature. A 24V high-capacity battery backup ensures continuous monitoring and data logging even during power interruptions.

Built for reliability and longevity, the ABT-HC-PLF-23 is backed by a two-year parts and labor warranty and a seven-year compressor warranty. With high-density urethane foam insulation and durable white powder-coated steel construction. Five adjustable shelves with rear guard rails maximize the 23 cubic foot storage capacity, while full-coverage LED lighting provides excellent visibility. The unit arrives ready to install on four preinstalled swivel casters with front locking capability, requiring only a standard 110-120V AC connection.
