Low temperature freezer, ET 03

The ET 04 Ultra Low Temperature freezer (-50 to -85 °C) is suitable for cooling the liquid for Gehman, TR-testers, and other Low Temperature Tests.

Elastocon freezing boxes have a highly efficient insulation resulting in very slow temperature rise. The insulation also results in a large inner volume, which together with minimal outer volume saves space and gives low energy consumption. This provides less influence on the environment as well as the pure environmental friendly refrigerant.

With a low noise level of less then <51 dB the freezers are ideally suitable for use in laboratory environments. They are supplied with a digital temperature display and acoustic temperature alarm. Thanks to construction no innerlids are needed.
