Featuring V-drive technology, Thermo Scientific™ TSX Series Ultra-Low Freezer provides temperature uniformity that adapts to your environment, protecting samples and offering significant energy savings. While conventional ultra-low freezers use single speed compressors that continually cycle on and off, the V-drive runs at variable speeds, adjusting cooling performance to the conditions inside and outside the freezer. When conditions are stable, the V-drive runs at a low speed, reducing energy consumption while maintaining a stable temperature for sample protection. When there are frequent door openings, or samples are added to the freezer, the system detects the activity and increases the drive speed.
