Environmentally Friendly Ultra-Low Temperature Freezer Requires Less Energy While Generating Less Noise

A new line of ultra-low temperature freezers was designed for both increased cryopreservation capability and improved performance in the laboratory environment.

The Thermo Fisher Scientific Inc. (Milford, MA, USA) TSX ultra-low temperature freezer features unique V-Drive technology. This hyper-cooling technology supersedes that of conventional ultra-low temperature freezers that continually cycle on and off, resulting in poor temperature recovery following door openings. V-Drive operates at a low speed to reduce energy consumption while maintaining a uniform temperature. When dealing with frequent door openings or when samples are added to the freezer, the control system detects the activity and increases the drive speed to bring temperatures rapidly back to the set point.

The TSX freezer operates with natural refrigerants with higher cooling efficiency that causes less environmental impact than classical refrigerants. This higher cooling efficiency requires up to 50% less energy than conventional refrigerant ultra-low freezers. V-Drive helps limit sound output as well, resulting in an instrument that is up to 20 times quieter, than conventional freezers.

The TSX freezer, which boasts water-blown foam insulation, includes a 600-box sample capacity storage area, an intuitive touch screen interface for access to vital freezer information, an on-board computer, and a USB port for data storage and exchange.

“Energy efficiency is a feature most lab managers and sustainability officers look for when making purchasing decisions, but energy savings can come at the expense of sample integrity,” said Chris Champlin, vice president and general manager of controlled temperature technologies at Thermo Fisher Scientific. “The new Thermo Scientific TSX ultra-low temperature freezer delivers unparalleled efficiency, noise reduction, and sample protection. Now, labs can not only reap the benefits of significant energy savings, but also feel confident that their samples are in an environment designed for their protection.”
