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.
