LAUDA - Loop Thermo - Electric Circulation Thermostats

The compact circulation thermostat for external applications from 4 to 80°C. 

The LAUDA LOOP circulation thermostat is sure to impress with its constant temperature between 4 and 80°C and astonishing flexibility. Its compact construction and low weight, as well as wide voltage input range of 100 to 240 volts, make it possible to put it to use flexibly and spontaneously anywhere in the world – the “Plug and Play” setup with quick-fit couplings makes it especially easy to use. The intuitive three-button softkey operation and simple menu navigation in five available languages via the well-lit, high-contrast OLED display make using the device a breeze.

The LAUDA LOOP product line includes two thermo-electric circulation thermostats for external temperature control. The temperature control thermostating is by means of a current flow via a semiconductor relay. Both heating and cooling can be achieved simply by reversing polarity in a small space. The two air-cooled device types, L 100 and L 250, provide cooling capacities of 120 and 250 Watts, as well as a temperature range of 4 to 80 °C. The focus is on applications requiring constant temperature with a low power requirement. Both device types are exceptionally efficient in partialload operation.
