San Diego/USA — These refrigerators are powered by compressor-free V-Drive technology, featuring synchronized temperature management (Stem), internal conditions are actively monitored and maintained at the desired temperature.

This includes constant monitoring of, and adjustments during, door-openings to minimize the negative impact of temperature fluctuations on samples. In combination, V-Drive and Stem provide uninterrupted temperature stability and uniformity throughout the internal chamber, the manufacturer claims. According to the company, the new TSX 505 refrigerators consume up to 37 % less energy than other models, translating to an average annual cost reduction of up to 30 %.

The compressor-less technology of these refrigerators also overcomes the common challenge of ‘humming’ experienced with many lab-grade refrigerators through its whisper-quiet operation at 35 dBA. This means that the unit can be kept in work areas without disturbing personnel or nearby patients. In addition, with no internal protrusions, such as overhead fans, users can benefit from up to double the storage space compared to similar models.

The undercounter refrigerators use refrigerants in compliance with the US Environmental Protection Agency’s (EPA) Significant New Alternatives Policy (Snap). Data logging capabilities are enabled through a USB port, allowing users to monitor storage conditions in a timely and efficient manner.
