Thermo Scientific TSU405SA High-Performance Undercounter Laboratory Refrigerator, 4.5 cu.ft.

Thermo Scientific™ TSU Series undercounter laboratory refrigerators are purpose-built from the ground up to fulfill the rigorous thermal tracking and stability criteria required in professional clinical, medical, and scientific research spaces. Delivering specialized temperature control alongside an advanced monitoring framework, these compact units guarantee complete protection for daily biological assets, reagents, and pharmaceutical stocks.

Model TSU405SA features a highly efficient 4.5 cu.ft. interior footprint engineered to operate within a precise laboratory thermal range between 2°C and 8°C. Built to adhere to strict international regulatory benchmarks, this model delivers NSF 456 certified performance, ensuring vaccine-grade temperature uniformity even during frequent door-opening intervals. To safeguard volatile compounds from unexpected failures, the unit integrates a comprehensive, full suite of security alerts, including wireless audible and visual high/low temperature, door ajar, and power failure alarms. Operating with a specialized compressor configuration, this refrigerator delivers whisper-quiet operation, preventing continuous loud humming and allowing laboratory personnel to work comfortably immediately adjacent to the cabinet.

The solid single swing door provides a tight thermal isolation envelope, shielding high-value contents from ambient room light and temperature fluctuations. The cooling loop utilizes eco-friendly green natural refrigerants, directly supporting global greenhouse gas emission reduction initiatives and sustainability targets. For seamless facility integration, the unit comes outfitted with built-in remote alarm contacts, allowing facility managers to link the refrigerator directly into centralized building monitoring systems. Complete with an automatic defrost cycle that continuously prevents operational frost accumulation without altering sample stability, and ENERGY STAR certification for optimized power consumption, the TSU405SA brings premium cold-chain security directly underneath standard facility workstations.

Features:

• NSF 456 Certified Performance Engineered to meet strict NSF 456 storage standards, delivering premium temperature uniformity and fast thermal recovery required for clinical vaccines and sensitive biologics.
• Full Multi-Hazard Alarm Suite Equipped with an advanced protective tracking system that triggers immediate alarms for high/low temperature breaches, door ajar alerts, and building power failures.
• Whisper-Quiet Workstation Operation Utilizes a specialized, low-noise acoustic cooling loop that ensures ultra-quiet performance, making it ideal for placement directly inside busy offices or quiet laboratory rooms.
• Eco-Safe Green Refrigerants Driven by advanced natural hydrocarbons and green refrigerants that minimize environmental impacts while significantly reducing global greenhouse gas emission footprints.
• ENERGY STAR Certified Efficiency Meets stringent global energy efficiency benchmarks, lowering building utility costs while optimizing the building's thermal HVAC footprint.
• Remote Alarm Integration Contacts Features factory-installed remote alarm terminal contacts, allowing technical teams to route system status updates directly into building-wide monitoring networks.
• Solid Swing Thermal Isolation Barrier Outfitted with a heavy-duty, solid single swing door that provides absolute protection against ambient light exposure and external room thermal drafts.
• Automatic Defrost Technology Employs an intelligent automatic defrost program that removes moisture accumulation from the evaporator array without threatening delicate sample structures.
