INTRODUCTION
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 heat
exchanger with extends fins. The fan is driven by an
Electric motor.
TECHNICAL
SPECIFICATIONS
Copper
Tubes:
The best quality imported (5/8") 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 coils. This
provides the toughness and durability required in the most
vital parts of the coil.
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 specially 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 optimum 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 tubes.
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 300psi for water application.
Computerized
Selection :
Speeds up and simplify the selection of right coil for
your specific requirements.
