Product Number: ABT-HC-PLF-49

Green-Leaf-ABSintertek-etl-listed-us-mark-seeklogo31 (002)

The ABT-HC-PLF-49 sets a new standard in premium laboratory freezing with its revolutionary variable speed compressor (VSC) technology, delivering ultra-quiet operation while achieving exceptional energy efficiency at just 8.69 kWh/day. This advanced refrigeration system self-adjusts to cooling demands, providing superior performance alongside significant energy savings and extended equipment lifespan. The unit maintains remarkable temperature uniformity of ±0.8°C and stability of ±2.1°C across its spacious 49 cubic foot interior, ensuring consistent conditions for your valuable samples.

Engineered for demanding laboratory environments, the ABT-HC-PLF-49 features a sophisticated Proportional Integral Derivative (PID) microprocessor controller with LCD display that maintains precise temperature control from -35°C to -15°C. The comprehensive alarm system includes visual and audible indicators for power failure, temperature sensor failure, high/low temperature, and door ajar conditions, with alarm logging capability. A 24V high-capacity battery backup keeps data logging active during power interruptions, providing continuous monitoring for your critical samples.

The ABT-HC-PLF-49 combines robust construction with thoughtful design features, including ten adjustable shelves with guard rails, double swing solid doors (right and left hinged), and full-coverage shielded LED interior lighting. The cabinet utilizes EPA-compliant high-density urethane foam insulation within a white powder-coated steel exterior, mounted on four preinstalled swivel casters with front locking capability. With an industry-leading seven-year compressor warranty and two-year parts and labor warranty, this premium freezer delivers the reliability and peace of mind your laboratory demands.
