Climatic Testing Systems designs and manufactures Large Walk-In Ultra Low Temperature freezers that can maintain a temperature of -70°C (-94°F) ± 0.5°C on a continuous basis with a temperature uniformity inside the ULT freezer compartment(s) of ± 3°C or better. In order to facilitate the distribution of the coming COVID-19 vaccines, large -70°C storage facilities will be required. CTS’ ULT freezers can store product in 1/3 of the footprint that would be required from small 25 ft3 upright freezers. There will be a considerable savings in utilities costs as well. CTS’ -70°C freezers can be customized per the customer’s needs and space requirements.
