Mod. CTc/EV manual with data logging
This equipment has been designed to experience with the construction principles and operational characteristics of cooling towers and it mainly consists of a packed tower of transparent metacrylate.
The water heated in a tank is pumped to the top of the tower and its flow rate is measured by a variable area flowmeter; then the water is distributed onto the packing uniformly to avoid any “channeling” phenomenon.
The cooled water is collected at the tower bottom and then it is sent again to the heated tank. An additional tank will keep the level of heated tank constant compensating the water lost by evaporation.
A forced air flow is blown by a centrifugal fan onto the column bottom; the flow rate of air can be controlled by an air lock and measured by a diaphragm at the column top. After leaving the packing, the air will cross a demister.
The heated tank is equipped with 3 electric heaters and with a safety thermostat. Process temperatures are measured by digital thermometers; a differential pressure gauge will measure the pressure drops on the packing and on the diaphragm.
