The standing devices are mainly recommended for thermostatizing external units at extremely low temperatures, but vessels can also be placed in its internal tank.
The high-performance compressor cooling system can reach a liquid temperature of up to -75 °C. The equipment was equipped with castors to make it easier to move.
All tanks are the same size, with a volume of 12 liters. The cooling-heating equipment can be ordered with a total of six types of controllers - T 150, T 200, TC 150 and TC 250. K-marked controllers (capable of energy-saving cryo-cooling control).
A more detailed description of the thermostat heads and their technical data (accuracy, heating power) can be found on a separate page.
