  • Water Cooling Tower Training System (HT - 017)
  • Hard copy user manual
  • BEDO software
  • Laboratory Pc

The educational unit (HT – 017) is designed to demonstrate the main components and principle of a wet cooling tower with forced ventilation.

  • Water is heated in a tank and transported by a pump to an atomizer.
  • The atomizer sprays the water to be cooled over the wet deck surface.
  • The water trickles from the top to the bottom along the wet deck surface whilst air flows from the bottom to the top.
  • The heat is transferred directly from the water to the air by convection and evaporation.
  • The air flow is generated by a fan and adjusted using a speed control.
  • The cooling column is transparent allowing clear observation of the wet deck surface and the trickling water.
  • The educational unit is supplied with digital displays to display all important process parameters are recorded (volumetric air flow rate, temperatures of air and water, air
  • Humidity, water flow rate) that are measured electronically.
  • The educational unit is provided with a software.
  • The measured values can also be transmitted directly to a PC via USB.
  • The changes of state of the air are represented in an h-x diagram.
  • Interchangeable cooling columns (not supplied by default) enable comparative studies.
  • The educational unit is provided with a DAQ software.
