The 60°C Horizontal Freezer series provides controlled low-temperature storage for biological samples, reagents, and temperature-sensitive materials in research environments. Available in five capacity configurations (58L, 120L, 220L, 320L, and 458L), these direct-cooling freezers maintain temperatures from -10°C to -60°C with microprocessor-based control and LED display interface.
The units feature ±2°C temperature uniformity and stability across the storage chamber, with 0.1°C temperature accuracy for consistent sample preservation. Integrated alarm systems monitor high and low temperature conditions as well as thermostat faults to protect valuable specimens. The horizontal configuration optimizes bench space utilization while providing easy access to stored materials.
How It Works
The freezer operates using direct-cooling refrigeration technology with R404A/R23 refrigerant to achieve and maintain temperatures between -10°C and -60°C. The microprocessor control system continuously monitors internal temperature through precision sensors, automatically adjusting compressor operation to maintain the set temperature within ±2°C stability limits.
Temperature uniformity across the storage chamber is maintained through optimized airflow patterns and thermal design, ensuring consistent conditions throughout the 58L to 458L storage volume. The LED display provides real-time temperature readout with 0.1°C accuracy, while integrated alarm systems continuously monitor for temperature excursions and system faults.
The horizontal configuration maximizes storage accessibility while minimizing bench space requirements. The direct-cooling system eliminates the need for forced air circulation, reducing temperature fluctuations and providing stable storage conditions for temperature-sensitive biological materials and chemical reagents.

Background reading relevant to this product:
What is the temperature recovery time after door opening?
Recovery time depends on ambient conditions and door opening duration, but the microprocessor control system typically restores set temperature within 15-30 minutes for brief access periods.
Can the unit maintain temperature during power outages?
The freezer does not include backup power systems. For critical applications, external uninterruptible power supply (UPS) or generator backup should be considered.
How is temperature uniformity validated across different capacity models?
Temperature uniformity should be validated using multiple calibrated sensors placed throughout the storage volume, with mapping performed at operational temperature for each specific capacity configuration.
What maintenance is required for optimal performance?
Regular maintenance includes cleaning condenser coils, checking door seals, calibrating temperature sensors, and documenting temperature performance according to laboratory protocols.
Are there data logging capabilities for temperature monitoring?
The unit features LED display monitoring; external data logging systems can be integrated for continuous temperature recording and documentation requirements.
What is the typical lifespan of the refrigeration system?
With proper maintenance, the direct-cooling refrigeration system typically provides 10-15 years of reliable operation under normal laboratory conditions.
How does performance compare between capacity models?
All capacity models maintain the same temperature specifications (±2°C uniformity, 0.1°C accuracy) with similar cooling performance characteristics scaled for chamber volume.
