CSZ’s patented Tundra® or Tundra II refrigeration system is ideal for customers testing their product down to -40°C or -54°C. Operating costs are reduced compared to cascade refrigeration systems since there is only one compressor now needed to run temperatures as cold as -45°C or -54°C. Operating cost savings up to 54% have been documented.
