The Armfield TH6 Film & Dropwise Condensation Unit enables students to gain a knowledge of two fundamental condensation processes and how they affect efficiencies and heat transfer, found in industries such as steam power plants and distillation operations.
Used to demonstrate dropwise condensation, demonstrated by means of the condenser with a polished gold-plated surface and film condensation which forms on the matt copper surface of the second condenser.
The pressure in the main vessel can be reduced using a water jet pump to allow the student to observe it’s influence. Additionally, boiling point can be varied by a combination of changing the pressure in the system and controlling the heating power or water temperature by simple controls. The TH6 additionally includes the ability to undertake experimentation into the influence of non-condensing gases on the condensation processes.
Sensors record the temperature, pressure (vacuum) and flow rates at all relevant points. These measured values along with heater power are displayed via the unique ArmBUS software system which also includes inbuilt equations and a data export functionality for off-line analysis.
