Thermo Scientific is committed to designing its TSX Series ultra-low temperature (ULT) freezers and fridges with the environment in mind. The TSX series is ENERGY STAR rated, meeting the established energy star criteria to deliver superior total performance for temperature management and reliability. A unique V-Drive technology uses a variable-speed compressor that will continually adapt to usage patterns and reduce energy.
Thermo Scientific™ TSX™ Ultra-Low Temperature Freezers (ULTs)
offer outstanding sustainability and sample protection. Efficient components, water-blown insulation, and clean hydrocarbon refrigerants are what set these ULT freezers among the leaders in the market today. Conventional-refrigerant ultra-low freezers can run up to 30 kWh/day in energy usage depending on age and size. Thermo Scientific ultra-low temperature freezers help save up to 70% energy compared to the previous generation of ULTs – that is up to 7,738 kWh less energy consumed during the year for one unit! If yours is a facility that uses several ULTs, that is an enormous amount of energy and associated cost saved.
TSX high-performance refrigerators and freezers
are powered by Thermo Scientific’s unique V-drive technology. This technology reduces energy consumption by up to 50% for refrigerators and 25% for freezers, compared to previous generations.1 With regards to the freezer this would save up to 2,245 kWh of energy over the course of a year.
V-DRIVE Technology – how it works
The TSX Series feature V-drive adaptive control technology, designed to minimize energy consumption without sacrificing sample security. While conventional ULT freezers use single-speed compressors that continually cycle on and off, the V-drive runs the compressors at variable speeds, adjusting cooling performance to the cooling demands inside and outside the freezer. When conditions are stable, the V-drive controls the system at a low speed, which helps reduce energy consumption while maintaining a stable temperature for sample protection. When there are frequent door openings or samples being added to the freezer, the system detects the activity and increases the drive speed
Some Energy-Saving Facts
- Older model ULTs can use up as much energy as an entire house! Upgrade your aging ULT to a Thermo Scientific ULT and save up to 70% of energy.
- Consider lowering your TSX ULT’s setpoint to -70°C and save up to 1,533 kWh annually per freezer
- Turning down your perimeter heater setting on the TSX high-performance refrigerators and freezers
can reduce your energy usage by up to 32%
- Upgrading your freezer from a previous generation can save up to 25% in energy usage over the course of a year
