The -40°C Freezer series provides reliable ultra-low temperature storage for biological specimens, pharmaceutical compounds, and temperature-sensitive materials requiring consistent conditions between -15°C and -40°C. These direct-cooling freezers feature microprocessor control with LED display and maintain temperature accuracy of ±0.1°C across three available capacities: 362L, 408L, and 450L.
Each unit incorporates comprehensive alarm systems for temperature deviations, power failures, and door monitoring, with recovery times ranging from 30-40 minutes to restore -37°C following door opening. The freezers utilize environmentally-appropriate refrigerants (R290 or R404A/R23) with wire-on-tube or finned copper tube condensers depending on model configuration, ensuring consistent performance in laboratory environments requiring precise temperature control.
How It Works
The freezers employ direct-cooling refrigeration systems using environmentally-appropriate refrigerants (R290 or R404A/R23) to achieve and maintain temperatures between -15°C and -40°C. The microprocessor-controlled system continuously monitors internal temperature through precision sensors, automatically adjusting compressor operation to maintain the setpoint within ±0.1°C accuracy.
Temperature uniformity is maintained at ≤4°C throughout the storage chamber through optimized airflow design and thermal insulation. The control system features LED display for real-time temperature monitoring and incorporates multiple alarm functions that activate upon temperature deviation, power failure, or door opening events. Recovery performance is engineered to restore -37°C within 30-40 minutes following door opening, minimizing exposure time for stored specimens.
The wire-on-tube or finned copper tube condenser configurations provide efficient heat exchange, while the direct-cooling design eliminates the need for fans inside the storage chamber, reducing temperature fluctuations and maintaining stable storage conditions for sensitive biological and chemical materials.

Practical Tips
Verify temperature accuracy monthly using calibrated reference thermometer placed in the center of the storage chamber.
Why: Regular calibration ensures continued precision for critical specimen storage requirements.
Clean condenser coils quarterly and check door seal integrity to maintain optimal cooling efficiency.
Why: Proper maintenance prevents performance degradation and extends equipment operational life.
Pre-chill storage containers and minimize door opening time to reduce temperature fluctuations.
Why: Reduces thermal load on the system and maintains stable conditions for stored specimens.
Organize samples with clear labeling and inventory management to minimize search time during access.
Why: Reduces door opening duration and exposure time for temperature-sensitive materials.
Ensure adequate ventilation around the unit and monitor alarm functions regularly.
Why: Proper ventilation prevents overheating while functional alarms provide early warning of storage failures.
Document temperature logs and alarm events for quality assurance and regulatory compliance records.
