1. TCLGC. Unit:

Anodized aluminium structure and panel in painted steel. Diagram in the front panel with similar distribution to the elements in the real unit.
Aluminium body (cylinder) with brass jacket that contains the test fluid and the refrigeration water. Variable heating resistance
(in the cylinder), computer controlled. The power is measured by a sensor.
6 Temperature sensors. Water flow sensor.

2. TCLGC/CIB. Control Interface Box:

With process diagram in the front panel. The unit control elements are permanently computer controlled. Simultaneous visualization in the computer of all parameters involved in the process. Calibration of all sensors involved in the process. Real time curves representation. All the actuators’ values can be changed at any time from the keyboard. Shield and filtered signals to avoid external interferences. Real time PID control with flexibility of modifications from the computer keyboard of the PID parameters, at any moment during the process. Open control allowing modifications, at any moment and in real time, of parameters involved in the process. 3 safety levels: mechanical in the unit, electronic in the control interface, and the third one in the control software.
