Description
KoolMore Ultra-Low 20 Cu. Ft. Lab freezer with Dual Inverters.
The KoolMore Ultra-Low Temperature Lab Freezer is designed to meet the rigorous demands of laboratory, pharmaceutical, and research environments that require precise, reliable cold storage.
With an ultra-low temperature range of –40°C to –86°C, this unit provides long-term protection for sensitive materials. Its dual inverter compressors and dual cooling system provide efficient operation, improved temperature uniformity, faster pull-down times, and added system redundancy.
With a spacious 20 cu. ft. capacity and a durable 304 stainless-steel interior, the freezer is built for daily use in demanding lab settings.
Precision microprocessor temperature control maintains accuracy within ±0.1°C, while a large 10.1-inch touchscreen delivers real-time monitoring, alarm management, and intuitive system control.
A multi-door design—featuring one outer door and four inner compartment doors—reduces cold air loss during access, helping maintain temperature stability.
Integrated data logging with USB export simplifies compliance and record keeping, while a rechargeable backup battery supports alarms and data logging for up to 17 hours during power outages.
UL certified, the unit is backed by a 1-year parts-and-labor manufacturer's warranty for added confidence and long-term reliability.
