The Bench Top Cooling Tower, "TTEB", includes a pump that impels hot water from the tank (with level switch and heating element) to the manifolds located at the top of the cooling tower. Water flow can be adjusted by a manual needle valve.
A temperature sensor located at the top of the unit measures the temperature of the water just before entering the tower. Water cools down as it falls through the manifolds of the tower, and finally falls into the tank where its temperature is measured again.
A fan propels atmospheric air with an accurate control of the air flow introduced in the tower. The air passes through wet bulb and dry bulb sensors before entering the column.
As air flows through the column, its temperature and humidity rise. On the other hand, water temperature falls. At the upper side there are other two dry bulb and wet bulb temperature sensors.
