These manual defrost laboratory freezers offer professional cold storage for scientific and industrial settings. Units come equipped with temperature alarms, keyed door locks, probe access, and precise temperature monitoring through microprocessor control.

Our Premier Series freezers include premium additions such as extensive alarm systems and digital touch pad displays. All units run on natural, hydrocarbon refrigerant for environmental health and energy efficiency.

Features

• Advanced Microprocessor Control: The system utilizes smart microprocessor regulation and continuous dual-probe monitoring (one in air, one in a glycol sample bottle) to maintain rigorous temperature consistency and immediate thermal recovery.

• Comprehensive Alarm Security: Equipped with automated audible and visual indicators for high/low temperature breaches, power failures, and sensor errors, alongside remote alarm contacts for 24/7 facility integration.

• Minimized Air Displacement: Featuring an innovative compartmentalized interior structured with six fixed shelves and seven independent inner doors to dramatically mitigate cold air loss during frequent main door openings.

• Commercial-Grade Construction: Built to withstand demanding institutional environments with a white powder-coated exterior steel shell, an airtight magnetic door gasket, and heavy-duty leveling legs.

• Sample Integrity Protection: The manual defrost mechanism operates strictly within a stable -15°C to -25°C threshold, purposefully preventing the cyclical warming periods inherent to automatic defrost systems.

• Industry-Standard Certifications: Fully ETL listed and conforming strictly to UL471 electrical standards, satisfying the strict risk-mitigation benchmarks required by North American laboratory inspectors.
