WATER COOLING TOWER
MODEL: HE 152
HIS Water Cooling Tower (Model: HE 152) has been designed to allow engineering students to get
familiarised with all the processes related to industrial force draught cooling tower. The basic unit
can be used with other columns to further assist students in the study of Thermodynamics,
Heat and Mass Transfer, Refrigeration and Air Conditioning.

DESCRIPTION
The unit is supplied with a packed column having
packing density of approximately 110 m2/m3. The
unit mainly consists of a load tank with a total of 1.5
kW electric heater, an air distribution chamber, a
make-up tank and a test column. Warm water is
pumped from the load tank to the top of the column
before being uniformly distributed over the top
packing. The thin film of water is cooled, as it passes
downward, due to evaporation. The cooled
water falls into the basin before going back into
the load tank where it is re-heated and recirculated. The load-tank water level is maintained
by means of a make-up tank.
A blower is installed on the unit to deliver air into
the air distribution chamber. The air passes a wet
and dry bulb thermometers before entering the
column. As the air passes up the column, its
moisture content increases and the water is cooled.
At the top of the column, the air passes a mist

EXPERIMENTAL CAPABILITIES
This Water Cooling Tower (Model: HE 152) shall allow
students to conduct these experiments:
♦ To study the water flow pattern and distribution.
♦ To measure all “end states”, and flow rates of water, air and make-up water.
♦ To plot the end states on a psychrometric chart
and to draw up energy balances using the steady
flow equation.
♦ To study the performance at different range of
cooling loads and inlet temperatures.
SPECIFICATIONS
a) Base Unit
Load tank with 0.5 kW and 1.0 kW electric heaters,
a float level control, make-up tank, circulating
pump, air blower and control panel.
b) Column (Column I)
Packed column made of clear acrylic with ten
decks of inclined plastic packing, water distribution unit and pressure tappings. Packing density:
110 m2/m3. Dimension: 15 cm(W) x15 cm(D) x60
cm(H).
c) Column Cap
Made of clear acrylic with sharp edge orifice, mist
eliminator and water distributor.
d) Instrumentations
Temperature measurements for water and air, dry
and wet bulb temperatures, inclined tube
manometer for air flow measurement, variable area
flowmeter for water flow measurement.

2. Column III:
♦ Similar to column I except with packing density of
200 m2 per m3
♦ To study the effect of packing surface area/volume
on the pressure drop across the packing and on
the wet bulb temperature at inlet.

taller with intermediate spaces in which the water
and air dry and wet bulb temperatures are
measured
♦ To measure the air and water properties at different
locations within the packing
♦ To construct the enthalpy driving force diagrams
♦ To determine the Characteristics Equation for
packing.
