Water Temperature Control Bench
The electrical cabinet receives the control plate wired by the student. This system is water self contained and only need a main power supply 230V. The operative part permits to heat and to cool a water tank.  Following the version of the electrical plate it allow to study.  The bench allows to study, then to wire by the student, a complete temperature control system. Instrumentation (transmitter, thermostat, controller. Power modulation (static relay, wave train, dimmer.Electric and thermal measurement. The bench is conformed to the last securities standards. 

Technical specifications:-
•  The cooling circuit is made out of a circulation pump and an aero-refrigerant allowing to increase the exchange of calories between the water and the ambient air. 
•  It permits to be water self contained. 
•  A 25 liters tank.
•  Its purpose is double.
•  A immersed electrical heater.
•  A temperature sensor.
•  A ” low level” sensor.
•  A security thermostat.
•  A stainless steel centrifugal circulation pump.
•  An aero-refrigerant.
•  To disturb the temperature control loop.
•  To cool the water tank in order to restart a new experiment (without having to wait for the natural water cooling).
