Thermo Scientific TSX Manual Defrost Freezer

Thermo Scientific TSX Manual Defrost Freezers are designed for applications in which even slight intermittent coil warming during auto defrost cannot be tolerated. They have features that support sample protection, sustainability objectives, and the U.S. Environmental Protection Agency’s Significant New Alternatives Policy (SNAP). Compared to conventional refrigerant, high-performance models, the TSX Series offers a whisper quiet operation, so you can bring the freezer out of the hallway and back into the lab or clinical environment, offering significant energy savings without compromising protection.

The variable speed compressor technology (V-Drive) is designed to provide temperature uniformity that continually adapts to the lab or clinical environment, offering significant energy savings without compromising protection. V-drive runs at variable speed to adjust cooling performance to the conditions inside and outside of the refrigerator. When combined with the automated tuning control, this variable speed drive optimizes the compressors running speed to the current conditions. When there are frequent door openings, or samples are added to the freezer, the control system detects the activity and increases the drive speed to bring temperatures back to the set point quickly. This innovative technology is one of the reasons the TSX Series delivers outstanding door opening recovery (DOR) speed, and more peach of mind for busy laboratories When conditions are stable, such as when the unit is running overnight or on weekends, the drive runs at a low speed, reducing energy consumption while maintaining a stable temperature for your samples.

These freezers are designed for applications requiring storage of reagents, pharmaceuticals, biological, and other commonly used laboratory materials such as primers, siRNA molecules, and fetal bovine serum (FBS).

TSX Series Freezers are compatible with Thermo Scientific DeviceLink HUB enabling you to have a connected experience with your unit so you know always – and anywhere – the safety of your samples and the performance of your refrigerator or freezer. The units are also compatible with Thermo Scientific SMART VUE wireless monitoring systems
