      Frequently Asked Questions - Liebherr Ultra-Low Temperature Freezers

      Liebherr ultra-low temperature freezers (ULT freezers) are designed to maintain temperatures between -40°C and -86°C, ensuring optimal storage conditions for biological samples, pharmaceuticals, and laboratory specimens.

      Liebherr ULT freezers use cascade refrigeration systems with high-efficiency compressors and hydrocarbon refrigerants for rapid cooling and stable temperature retention. These systems ensure precise control, even in fluctuating ambient conditions.

      Our freezers use multi-layer insulation, advanced air circulation technology, and high-performance gaskets to minimize temperature deviations. The microprocessor-controlled system continuously monitors and adjusts cooling cycles to maintain uniform temperatures throughout the chamber.

      Liebherr ULT freezers include built-in alarm systems for: High/low temperature deviations Power failure alerts Door ajar warnings Sensor malfunctions Battery backup notifications for monitoring continuity Additionally, these alarms can be connected to remote monitoring systems for real-time alerts.

      To ensure continuous operation during power outages, we recommend: Uninterruptible Power Supply (UPS) systems for short-term power backup Liquid CO? or LN? backup systems for extended temperature retention Dedicated emergency power generators for long-term protection

      Routine maintenance ensures optimal performance. We recommend: Monthly filter cleaning to prevent airflow blockages Quarterly door seal inspections to maintain airtight conditions Annual condenser and evaporator coil cleaning to optimize cooling efficiency Regular sensor calibration to ensure precise temperature control

      Liebherr ULT freezers are not designed for volatile or explosive substances. For flammable material storage, a spark-free or explosion-proof model should be used. Always check with safety regulations before storing hazardous materials.

      Genuine Liebherr compressors, gaskets, temperature probes, and control boards can be ordered from our official Liebherr Parts Store. Using original parts ensures compatibility and maintains warranty coverage.

      To reset the freezer: Press and hold the reset button (if available) on the control panel. Turn off the unit and disconnect from power for 5 minutes.
