Thermo Scientific TSX3020FA – High Performance Freezer (-25°C to -15°C), 115V/60Hz, 29.2 Cubic Foot Capacity

Thermo Scientific TSX3020FA – High Performance Freezer (-25°C to -15°C), 115V/60Hz, 29.2 Cubic Foot Capacity

Thermo Scientific TSX Series high-performance -20°C manual defrost freezers are designed with features that support sample protection and sustainability objectives for clinical and laboratory-grade storage requiring -20°C. The Series’ V-drive technology is designed to provide temperature uniformity that continually adapts to user patterns, offering significant energy savings without compromising protection.

Temperature variation can have an impact on the viability and efficacy of vaccines, medication, reagents and other temperature-sensitive materials. These variations can shorten product shelf life, degrade enzymes and reduce vaccine effectiveness. Therefore, it is important to choose a high-performance system which has been designed for the demanding standards of the laboratory and clinical environment.

Several models available

Thermo Scientific -20°C freezers are available in two sizes, as well as 115V or 208-230V. The following is an overview of available systems.

For users working with enzymes, there is a separate group of freezers for that specific application which contain enzyme bins. Please see the catalog for more information.

Sample integrity and energy savings

The performance and energy savings of the new TSX Series are driven by Thermo Scientific’s unique V-drive technology.

• While conventional, high-performance refrigerators and freezers use single speed compressors that continually cycle on and off, the TSX Series V-drive runs at variable speeds to adjust cooling performance to the conditions inside and outside of the refrigerator or freezer
• 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 refrigerator or 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 peace 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

Standard compressors cycle ON & OFF

Variable speed compressors (V-Drive) change speed. As shown in the above graphic, the TSX V-drive, unlike standard compressors that cycle on and off, adjusts to factors such as start-up and door openings, when a higher compressor speed is needed. During normal running time when the door is closed, the V-drive runs at a lower speed to maintain your setpoint.
