The LOOP product range includes two thermo-electric circulation thermostats for external temperature control.

• Compact units which are not heavy
• Refrigerant-free temperature control with Peltier technology
• Power-regulated ventilator fan
• 3-button controls with OLED display
• Heating and cooling functionality via the same components
• Voltage: 100 to 240 V, 50/60 Hz
• RS232 interface as standard

Temperature control is by means of a current flow via a semiconductor relay. Both heating and cooling can be achieved simply by reversing the direction of current flow in a small space. The focus is on applications requiring constant temperature with a low power requirement. Both device types are exceptionally efficient in partial-load operation.
