Cincinnati Sub-Zero (CSZ) is a leading provider of standard and built-to-order environmental test chambers including: temperature, humidity, stability, altitude, thermal shock, temperature/humidity/vibration, HALT/HASS chambers, industrial freezers, sand & dust chamber and more.

Test chamber sizes range from small benchtop chambers to full walk-in/drive-in rooms. Temperatures range from -80°C to +190°C with humidity ranges from 10% to 98% RH.

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. 

All test chambers feature CSZ’s EZT-570S controller which operates like a smart-phone. It includes data logging, data file access with memory stick, Ethernet control and monitoring, alarm notification via email and/or phone text message, data file backup system, full system security,  power recovery options and more
