Water/Spray Tanks
2-1
Conair Water and Spray Tanks are designed to provide addi-
tional spray or flood cooling of extruded profiles, tubing and
pipe, or as a primary spray or cooling tank. Leveling floor
jacks and adjustment handwheels at both ends of the tank
ensure proper alignment with the extrusion line.
WHAT IS THE
WT OR ST
TANK?
After an extrusion has been sized and solidified, it may
require additional controlled cooling to obtain the desired
characteristics.
The WT water tank provides flood cooling. You can sub-
merge the extrusion in heated water to slow the cooling rate,
or in cool water to cool it more quickly. The internal plumbing
configuration for flood cooling is designed to provide maxi-
mum turbulence to break up the temperature strata that forms
around the extrusion for optimum heat transfer. Support and
hold-down rollers keep the buoyant extrusion in place as it
passes through the tank.
The ST spray tank reduces the buoyancy of the extrusion in
the water and provides maximum heat transfer through evapo-
ration by spraying water onto the hot extrusion surface. The
extrusion can be held above the water level or submerged in
the water in the spray compartment.
Both WT and ST tanks have two compartments: a long water
or spray compartment for controlled cooling of the extrusion,
and a short air-wipe compartment for removing water from the
pipe surface as it leaves the water or spray compartment.
The water and spray compartments are sealed by gaskets on
each end. Black wiping gaskets backed up by red support
gaskets retain the flood and spray water.
An optional closed water recirculation reservoir, pump and
heat exchanger can interface with your portable chiller or cen-
tral chiller for reduced water consumption.
Water Spray Tanks
UGE014/0999

DESCRIPTION
The extrusion enters the water or spray compartment after
leaving the calibration tooling or a sizing tank. Simple support
and hold-down rollers ar used to hold small diameter hollow
forms in position as the extrusion passes through the tank.
Contoured support and hold-down rollers usually are required
for large hollow forms.
HOW IT WORKS
In a WT water tank, the extrusion is submerged in a flooded
water compartment. Water enters the compartment through a
quick fill valve or through one center-supply, drilled water
header that is mounted along the top and back side of the
compartment. The water level is controlled by a telescoping
overflow standpipe.
In the ST spray tank, the extrusion may be submerged or
held above the water.
All water enters the compartment
through four center-supply water
headers mounted at the four
corners along the full length of the
compartment. These water headers
are drilled or equipped with spray
heads. Each pair of spray headers
has its own water supply valve.
Water levels are controlled by the
setting of the standpipe. When set
low, the standpipe keeps the water
level below the extrusion. When set
high, the standpipe allows com-
plete submersion of the extrusion
in a flooded compartment.
The extrusion passes from the water or spray compartment
into an air-wipe compartment equipped with two, tubular air
wiper rings connected to compressed air. Angled holes drilled
in the wiper ring blasts air on the extrusion in the direction of
the extruder to blow off surface water. A gasket seal at the
exit of the air wipe compartment ensures the extrusion will be
dry as it reaches the puller.

ꢀ Tank: The stainless steel, all-welded tank has two com-
partments: a long water or spray compartment and a short
air-wipe compartment. Spray header water connections are
stainless steel fittings welded through the tank bottom. The
air wipe compartment has two drilled copper blow-off rings
mounted concentric to the extruded product. The rings are
drilled at an angle to generate water blow-off forces oppo-
site to the direction of extrusion flow. Air supply is
through the front sidewall of the compartment. A throttling
valve is supplied.
Bulkheads are equipped with studs for applying gaskets.
Black gaskets wipe the extruded product. Red gaskets pro-
vide dynamic sealing.
ꢀ Tank Support: The tank support system provides for
(1) accurate vertical positioning of each end of the tank to
meet centerline height requirements,
(2) for accurate horizontal positioning of each end of the
tank to meet tank centerline alignment requirements, and
(3) accurate axial positioning of the tank.
The system is comprised of two basic elements: a micro-
height adjusting system to move the tank up and down and
a tank cradle system that cages the tank and carries means
for horizontal and axial positioning.
ꢀ Water Supply System: Water is supplied from a short
water supply header carried on the tank. A ball valve con-
trols water to each spray header. This valve is used to mod-
ulate water to the tank. On small water tanks with one
spray header, the second valve is used for "quick fill". On
long tanks a third ball valve directs water to an end port to
assist in "quick fill".
UGE014/0999
Water/Spray Tanks
DESCRIPTION 2-5
ꢀ Tank Drain System: All tanks have overflow stand pipes
that continuously carry modulating water to the drain with-
out drain valving. To drain the tank quickly, one to three
drains are supplied, depending on the tank length and tank
size. Additional tank drains, controlled by gate valves,
empty into the tank drain header pipe. The header pipe,
made of rigid PVC with demented fittings, is attached to
the base frame and slopes toward the extruder.
FEATURES AND
OPTIONS (CON.)
The large drain size provides unrestricted water flow to the
plant drains or plant water recovery system.
ꢀ Casters and Wheels: The tank base is supported at all four
corners by vee grooved casters. Plain wheels are available.
ꢀ Leveling Jacks: After positioning the tank, it is necessary
to anchor the tank against line forces. Two leveling jacks
(floor locks) are provided on one side of the base, effective-
ly anchoring the tank in place.
ꢀ Vertical Adjustment System: The tank support system is
moved vertically up and down on each end to position the
centerline and to level the horizontal plane. The cradle car-
rying the tank rests on micro-height adjusting plate at each
end. The cradle is caged axially by angles welded to the
micro-height plates. The small handwheel horizontally
mounted to each micro-height plate engages a worm gear to
drive a vertically mounted threaded rod. When the hand-
wheel is rotated, that end of the tank is moved up or down.
The adjustment is self locking.
ꢀ Horizontal Adjustment Option: To allow side-to-side
positioning, the sides of the cradle are moved away from
the tank. Rotation of knobs, which drive threaded blocks
beneath the tank, moves the tank side to side.
ꢀ Axial Adjustment Option: This option allows you to
move the tank backward and forward (longitudinally) in a
precise manner, with positive locking at any position. The
tank is supported on caged solid rollers running in short
tracks to allow easy movement. Rotation of the large hand-
wheel produces axial motion of the tank, depending on the
status of the detent arm. When the detent is disengaged, the
shaft is free to turn and the tank will move toward the
puller. When the detent is pushed in and engaged, the one
way locking action of the bearing on the shaft prohibits
shaft rotation and the tank is locked in position. The detent
must be removed if tank movement toward the puller is
desired.

DESCRIPTION
ꢀ Closed Water Recirculation System Option
FEATURES AND
OPTIONS (CON.)
The system includes a reservoir (sump tank), pump and
heat exchanger. .On a closed water pump system, spray
water introduced into the tank through the spray headers is
drained to a sump tank. The water is then pumped back to
the spray water supply header for control by the header
valves. The sump tank, filled from customer's water supply,
has automatic water level control. The pump has a suction
filter inside the sump tank at the pump port. The pump is
mounted on the bottom tank frame members. Two pump
choices are available: centrifugal and gear.
The 5 Hp centrifugal pump has a capacity up to 60 GPM
at 70 PSI, and is self protecting. It can be operated without
damage with the spray header valves fully closed.
The 2 Hp gear motor has a capacity of about 16 GPM. A
relief valve on the output of the pump directs water to the
tank to protect the pump if the spray header valves are fully
closed.
ꢀ Sump Tank Option: On recirculating systems, a sump
tank holds water for the open loop systems. Bottom tank
frame members support the sump, which is caged but not
anchored. The overflow PVC drain fitting is dual purpose,
reversible. As installed, the NPTF is outboard for screwed
piping. When the fitting is reversed, external piping may be
cemented into the sweat end.
ꢀ Circulation Pump Option: A Crane circulating pump is
normally used to move tank water across the optional
immersion heating elements or optional cooling coils. The
pump is hard piped to the tank and moves with it. Water
flow is parallel to extrudate flow. The pump is operated at
120 volts through a step down transformer with the primary
at 230 or 460 volts, single phase, 60 HZ. Power require-
ments are about 0.5 KVA.
ꢀ Immersion Heater Option: The 230 volt, 3 kW, single-
phase tubular electric heater is a self contained unit with
off-on control and a temperature setting control dial. The
unit is mounted through the sidewall of the tank and
extends into the space below the extrusion. A pump is
applied to move the tank water over the heater tubes to
modulate end-to-end water temperature. The immersion
heater is supplied direct at 230 volts but requires a 3 KVA
transformer at 460 volts. The transformer is mounted in the
lower part of the tank frame. Care must taken to ensure that
the heater tubes are always immersed during operation, and
that the heater is turned off before draining tank water.
UGE014/0999
Water/Spray Tanks
DESCRIPTION 2-7
ꢀ Cooling Coils Option: Cooling coils remove heat buildup
in water. Connections are made with bulkhead fittings
through the rear wall of the tank, slightly above the high
water level. Inlet and outlet connections are close together
for easy connection to chilled water. When cooling coils are
supplied, the cooling coils placed in the sump tank and the
water tank are shaped to cover the bottom of the tank.
Connections are NPTF.
FEATURES AND
OPTIONS (CON.)
ꢀ Tank Covers Option: Water tanks seldom require covers
as there is little or no splashing. However, spray tanks with
their cross spray patterns, may require covers.
ꢀ Thermometers Option: On water tanks, thermometers
may be mounted through the tank sidewall to monitor water
temperature in the tank. On a tank with a gear pump sys-
tem, the thermometers are mounted through the sump tank
sidewall to monitor temperatures in the sump that indicates
the temperature of water to the tank.

❒ A grounded 3-phase power source supplying the
correct current and voltage for the recirculation sys-
tem on your tank. Check the serial tag for the correct
amps and voltage. Electrical power is required only if
you have the recirculation system option.
❒ Minimum clearance for safe operation and mainte-
nance. The distance, or air gap, between the face of
the die or sizing tank and the upstream end of the
WT/ST tank may be up to 12 inches (305 mm). Allow
at least 12 to 24 inches (305 to 610 mm) between the
downstream end of the tank and the upstream end of
the puller to roll the tank away from the extruder for
maintenance.
Determine the correct position for the tank on
the extrusion line.
2
There may be an additional cooling tank or an optional
laser gauge/diameter gauge between the downstream end
of the WT/ST tank and the puller. Allow 1 to 2 feet (305 to
610 mm) between the WT/ST tank and an additional cool-
ing tank. Allow 1 to 3 feet (305 to 914 mm) between the
WT/ST tank and a laser gauge and between a laser gauge
and the puller.
Install v-rails. If your tank comes with v-groove cast-
3
ers, you may choose to use v-rails to insure repeatable
tank alignment. The overall length of the rails will be
determined by equipment sharing the rails. The v-rails
should be long enough to move all downstream equipment
away from the extruder for removal of the screw.
Typically, the rails should be 2 to 4 feet (610 to 1219 mm)
longer than the WT/ST tank. The distance between the
centers of the v-groove casters on standard WT/ST tanks is
22 inches (558.8 mm). Optional widths may have been
ordered.

The WT tank provides cooling through tank water flow, while
the ST spray tank cools with water flow and water sprayed
onto the extrusion Immersion rollers inside each tank cham-
ber keep the extrusion positioned for even cooling.
PREPARING FOR
OPERATION
Determine the cooling mode you will use.
The best cooling mode and roller position for your profile
depends upon your material and process.
1
ꢀ
Immersion cooling: The extrusion should be fully
immersed in the tank water. The immersion rollers are
usually positioned above the extrusion to keep it sub-
merged.
ꢀ
Spray cooling: The extrusion is cooled by water
sprayed over its surface. An inch or two of runoff
water flows below the extrusion. The immersion
rollers are usually positioned below the profile.
Make sure the extruder and puller are ready.
The extruder should be discharging melt or extrudate that
is up to the correct temperature. Set the extruder and
puller at minimum speed.
2
3
Center the tank with the extrudate. During
installation, you aligned the tank with the extrusion line.
Before each operation of the tank, you should fine tune
the height and side-to-side position of the tank to align it
with the center of the extrudate.
Height Adjustment:
Looking down from above the tank, turn the small hand-
wheel to move the tank toward or away from the operator
side until it aligns with the center of the extrudate as it
exits the die.
Side to Side adjustment:
Kneeling at the upstream end of the tank at eye level with
the die, turn the large, spoked wheel to adjust the tank
height until it aligns with the center of the extrudate.
Turn on the water supply to fill the tank.
Adjust the standpipe for the water level you want to main-
tain. If you have the optional recirculation system, make
sure the water level in the reservoir is above the pump
input before proceeding.

Move the tank back upstream for normal
operation. Turn the linear actuator handwheel to move
the tank upstream to within 1 inch of the extruder die face,
or to within 1 to 12 inches of the end of a sizing tank.
Recheck the tank alignment. With the extrudate
threaded, verify that the tank is precisely aligned with the
center of the extrudate.
8
9
Position the immersion rollers to prevent the
extrusion from sinking or floating. Slide each
roller a up or down to the desired position. The best posi-
tion for the rollers depends upon your material, process
and cooling mode.
