The TSX freezer offers lower power consumption

A new ultra-low temperature freezer from Thermo Scientific offers laboratories lower power consumption, less noise and higher efficiency without compromising the integrity of samples.

The TSX features natural refrigerants for lower environmental impact and higher cooling efficiency. It is said to use up to 50% less energy than conventional refrigerant ultra-low freezers and delivers temperature uniformity that continuously adapts to a laboratory’s environment.

Conventional ultra-low temperature freezers normally use single-speed compressors that continually cycle on and off, resulting in poor temperature recovery following door openings. Thermo Scientific says the TSX is the only freezer of its kind equipped with V-Drive technology, which, when conditions are stable, 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 quickly back to the set point.

The V-Drive also helps limit sound output to 46db(A), making the TSX up to 20 times quieter than a conventional refrigerator, says Thermo Scientific.

Additional features include the use of water-blown foam insulation, which eliminates the off-gassing typical of urethane-insulated freezers, as well as a 600-box sample capacity to maximise storage within a 1.06m2 footprint, touch screen interface for access to vital freezer information, and on-board computer and USB port for data storage and exchange.
