FUNCTION & FEATURE
DRY COOLING TOWER is an equipment which is used to cool and maintain
the temperature of process hot water at a particular level. This
operates on the principle of heat transfer by a hear exchanger with
extended fins. The fan is driven by an Electric motor.
Copper Tubes
The best quality imported (5/8") OD copper tubes in Level Wound
Coils are used. This ensure coils with the minimum number of joints
by forming a hair pin bends as well as to form a uniform wall thickness
that eliminates embarrassing and expensive leaks after installation.
Tubes are staggered in the path of airflow for better heat transfer
efficiency.
Return Bends
They are die-formed from thick walled tubing that is heavier than
the standard tubing used in the rest of the coils. This provides
the toughness and durability required in the most vital parts of
the coils
Headers
Inlet and outlet headers are constructed of heavy wall steel pipes
with shoulders formed at each brazed connection to the 5/8" tube
in the coil. This shoulders intruded with special tooling provides
the strength to the brazed joint that eliminates another source
of leak during transit and installation.
Mechanical Tube Expansion
Tubes are Mechanically expanded for an optium bond between tube
and fin. This positive and controlled expansion procedure provides
a clean, smooth inner tube surface for allow water pressure drop
and guarantees uniform heat transfer between tube.
Heat Transfer Coils
Improved Circuiting
The GEM Cooling Tower Design of water circuiting provides flexibility
in selection and unequaled performance optimization. All inlet and
outlet connections are provided on the same end thus reducing expensive
piping and installation costs.
Rigid Construction
A die formed galvanized steel frame provides stacking and shipping
support and protection against tube damage during expansion and
installation.
Venting, Draining and Expansion Tank
Each water duty coil is provided with a convenient vent connection
at the highest point and a drain connection at the lowest point
apart from a small expansion tank.
Pressure Testing
Each coil is pressure tested after manufacture, by air under water
at 300 psi for water application.
Computerized Selection
Speeds up and simplify the selection of right coil for your specific
requirement.
CONSTRUCTION AND OPERATION
Dry Cooling Tower is mounted on a heavy duty channel base frame.
Non corrosive fibre glass / GI panels are used for enclosure.
Aero dynamically balanced high efficiency axial flow fans with
low noise are used.
The motors are IP 55 class with extended SS shaft. The low speed
of the motor minimises noise and increases efficiency. Motors are
specially designed to withstand moisture, rain and dust.
The hot water from the diesel engine is sent
to the inlet of the Dry Cooling Tower. This hot water is cooled
and cold water from the outlet of the cooling tower is connected
to a pump which pumps the water to the diesel engine (or any other
load) to pick up the heat from the generator.
