HNZXIB 58L -86°C Vertical Ultra-Low Temperature Freezer laboratory supply

58L vertical freezer for lab storage

The HNZXIB 58L vertical ultra-low temperature freezer provides 58 litres of capacity for laboratories that require reliable sample preservation at extreme cold. It operates on a 110 V, 60 Hz supply and draws 3.1 A at a rated 450 W. The 304 stainless steel interior resists corrosion and is designed for friendly use in demanding environments. Digital microprocessor control maintains the chamber between -40 °C and -86 °C with 0.1 °C accuracy.

Upgrades from higher-consumption units

The mixed-refrigerant, single-level auto-cascade refrigeration system reduces energy consumption by 50 % compared with conventional designs while improving temperature uniformity by 30 %. Direct cooling and manual defrost simplify the refrigerant circuit, using fewer components for easier maintenance. Power consumption is 6.5 kW per 24 hours, making the jump worthwhile for facilities that run freezers continuously and need lower operating costs without sacrificing the -86 °C lower limit.

Check voltage, clearance and alarm needs

Verify that the installation site supplies 110 V, 60 Hz power and can accommodate the exterior footprint of 540 × 620 × 1115 mm plus clearance for the four lockable casters. The built-in backup battery sustains the digital display and audible-visual alarms for 72 hours during a power outage, so confirm that the alarm features meet your monitoring protocol. Keyboard lock and password protection prevent unauthorised parameter changes, and the removable inner door and condenser dust gauze simplify routine cleaning and defrosting.
