IMPORTANT
Since Recold heat exchange coils are copper, the coil can be drained without regard to
internal corrosion. This must be considered with steel tubes that do not have internal
protection.
RECOLD HYDROSPRAY
Recold engineering has developed an exclusive
water distribution system called hydrospray. This
unique system provides optimum water coverage
of the heat transfer coil for maximum efficiency and
virtual elimination of harmful scale problems that
result from uneven water distribution. This process
is accomplished through a limited number of large
orifice non-clogging diffusers mounted on a heavy
duty PVC pipe water header.
Recold / JW Series Fluid Cooler / Construction 3
The JW Evaporative Fluid Cooler is a ruggedly built unit constructed to provide many years of durable,
dependable service with minimal maintenance requirements. Quality materials and workmanship are a key
factor in meeting this objective.
FAN MOTORS
Fan motors furnished as standard equipment are open
drip-proof type suitable for outdoor service. Motors
have a 1.15 service factor and are mounted on a
heavy duty adjustable base located for easy access.
FAN GUARD SCREENS
All moving parts are protected with OSHA approved
galvanized steel screens. Each guard is easily
removed for access to the fan.
FAN SECTION
The centrifugal fan is
forward curved, statically
and dynamically balanced
and constructed of
galvanized steel. The fan
housing has curved inlet
rings for efficient air entry
and discharge into the
pan. Fans are mounted
on a solid steel shaft
coated to resist corrosion.
Heavy duty, pillow block
type, self-aligning ball
bearings are located at
each end of the fan shaft.
No intermediate bearings are
required
Extended lube lines are supplied as standard
equipment to allow servicing bearings without
removal of fan guard screens.
WATER CIRCULATION PUMP
The water circulation pump is a close coupled, bronze
fitted centrifugal type with mechanical seal. Each
pump is factory mounted and piped. Standard motor
is open drip-proof suitable for outdoor service.
DRIFT ELIMINATORS
Eliminators are constructed of PVC assemblies in
removable, easy to handle sections. Each section has
a three break design allowing three changes in air
flow and measure approximately 5 inches in depth.
The use of durable PVC eliminates the corrosion
problems associated with galvanized eliminators.
HEAT EXCHANGE COIL
Coil tube bundle is constructed of 5⁄8" copper
tubing with stainless steel tube sheets
and copper headers. The copper
construction offers a
noncorrosive coil for extended
service life.
ACCESS DOORS
Large rectangular access
doors are strategically
located to provide access
to both upper water
distribution system and
lower pan basin. The
patented doors provide a
complete air and water tight
seal without the use of
gaskets or fasteners
WATER MAKE-UP
Water make-up is provided
by a solid brass float valve with arm
and float ball installed in an external float
b o x . This allows easy observation of the water
operating level and maintenance of the valve with unit
in operation.
Construction: The Evaporative Fluid Cooler sump pan is constructed of 300 stainless steel and casing panels
are constructed of heavy gauge, G-235 galvanized steel. The sump pan and casing panels are flanged outward
so that all the connecting fasteners are located outside the flooded section of the unit to help prevent leaks
in the unit and provides a more permanent watertight joint. To provide further protection from corrosion, no
welded joints are located below the water line. The unit is designed for a 30 psf on any projected area and ships
in one piece on a minimum 6" high stainless steel channel base to help in handling and installation of the unit.

Recold / JW Series Fluid Cooler / Freeze Protection 6
For the most part, evaporative closed circuit coolers
will be installed for operation on a year-round basis.
Units installed in a cold climate must be provided with
adequate freeze protection for both the recirculating
water and the heat exchange coil for proper
equipment operation and maintenance.
RECIRCULATING WATER
The operation of evaporative cooled equipment under
approximately full load conditions will prevent freezing
of the recirculated water. However, during periods of
very little or no heat load when fans and pumps are
shut down, some form of freeze protection must be
used.
A simple form of freeze protection commonly used
is a remote sump tank inside a heated building
below the evaporative cooled equipment. The water
circulation pump is located at the remote tank
circulating water through the evaporative cooler
during load conditions. When the unit is shut down,
the water drains down into the remote sump tank
which is in a heated atmosphere.
The remote sump installation may be unacceptable in
some cases due to unit location or space limitations.
For these applications, pan water freeze protection
may be attained by means of an optional electric
heater located inside the unit pan. Electric pan
heaters are designed to prevent pan water freezing
during unit shut down with fans and pumps idle.
Water lines to and from the unit, pump, pump
discharge and drain lines must be wrapped with a
heat-tracing element and insulated to protect them
from freezing.
HEAT EXCHANGE COIL PROTECTION
The best means of heat exchanger coil freeze
protection is to circulate an ethylene glycol water
solution. The solution freeze points with respective
ethylene glycol by volume are given in Table 11
below. This method will allow freeze protection
irrespective of heat load or unit shut down.
Some applications will not permit the use of an
ethylene glycol solution. Under these circumstances,
other means of freeze protections must be used and
the following rules strictly adhered to.
1. Maintain full flow through the coil
2. Maintain heat load on the coil at all time so that the
leaving water temperature does not drop below
+50°F
Full flow alone will not protect the coil.
Temperature of +50°F must also be maintained.
Methods of maintaining the recommended fluid
temperature may vary with system design and
operation. A simple means of preventing heat loss
may be to locate the unit indoors allowing a heated
atmosphere. Adequate space and ductwork must be
provided for proper operation.
Units operating in low ambient conditions with a
heat load which becomes very low or drops off
completely may require the addition of an artificial
load to maintain safe fluid temperature. The amount
of artificial load required may be reduced by means
of discharge positive closure dampers. The addition
of the dampers will prevent induced air circulation or
the chimney effect which may occur during unit shut
down.
The above methods of coil freeze protection, when
properly applied and maintained will provide good
equipment protection. All methods, other than
those using an adequate antifreeze solution, should
provide a means of emergency coil draining. It is
recommended that automatic drain valves and air
vents with vacuum breakers be installed on each
coil circuit. Adequately size drains with heat-tracing
tape and insulation should be provided for free
drainage. Should the circulating pump fail or the water
temperature leaving the coil drop below 50°F for any
reason, the coil will automatically drain preventing
freeze damage.

Recold / JW Series Fluid Cooler / Selection Procedure 7
Closed circuit cooler selections can easily be made by using the information on pages 6 through 11. The
examples below demonstrate proper procedures for water and ethylene glycol solutions. Other fluids can be
cooled, but since their heat transfer and flow characteristics may vary, please contact your local Recold sales
representative for assistance.
WATER SELECTION EXAMPLE
Select a unit to cool 225 GPM of water from 102°F to
90°F at 76°F wet bulb temperature.
1. Determine Range:
102°F - 90°F = 12°F Range
2. Determine Approach:
90°F - 76°F = 14°F Approach
3. Select Load Factor — Enter Unit Load Factor Table 2
for 76°F wet bulb. Select load factor based on
12°F range and 14°F approach. Load factor in this
example equals 3.3. When wet bulb temperature
is an odd number interpolate between appropriate
tables to determine the load factor.
4. Select Unit Model — Table 3, the load factor
determined in step 3 falls between 3.0 and 3.5.
Enter the 3.0 column and read down to the smallest
unit flow rating which is greater than or equal to
225 GPM. For the Model JWL35B, interpolate
between 245 and 190 GPM to determine the
flow rating at the 3.3 load factor. Interpolation
gives a rating of 212 GPM which is less than the
design requirement. Select a Model JWL35C and
again interpolate between load factor columns
to determine flow rating. The second selection
provides a flow rating of 245 GPM which exceeds
the design requirement. The correct unit size is,
therefore, a Model 35C
5. Determine Flow Limitations — Enter Table 3 at unit
size determined in Step 4 to select a JWL low flow
or JW standard flow unit. The Model 35C with 225
GPM design flow falls within the standard coil flow
limitations. The correct unit selection is, therefore,
a JW35C.
6. Determine Coil Pressure Drop — Enter the Coil
Pressure Drop Table at 225 GPM and read across
to the unit model column to select pressure drop
reading. In this example, pressure drop equals
4.8 PSI.
ETHYLENE GLYCOL EXAMPLE
Select a unit to cool 75 GPM of 40% by volume
ethylene glycol from 107°F to 85°F with 78°F wet
bulb.
1. Determine Range:
107°F - 85°F = 22°F Range
2. Determine Approach:
85°F - 78°F = 7°F Approach
3. Select Load Factor — Enter Table 2 for 78°F wet bulb
and select load factor at design range and approach.
Select 6.0 factor.
4. Select Test Unit Model — Enter the Unit Rating
Table 3 at the 6.0 load factor and read down to the
smallest unit flow rating greater than or equal to the
design 75 GPM. Select the test model JWL35C
5. Correct Flow for Ethylene Glycol — The flow correction
factor obtained from Table 1 is 1.04. 75 GPM x 1.04
= 78 GPM
6. Adjust Model Selection — Re-enter Table 3 at the 6.0
load factor and make selection based on corrected
flow of 78 GPM. The adjusted unit selection is the
Model JWL50A indicating an 80 GPM rating
7. Determine Flow Limitations — Enter Table 3 at unit
size determined in Step 6 to select a JWL low flow
or JW standard flow unit. The Model 50A with
75 GPM design flow falls within the low flow coil
limitations. The correct unit selection is, therefore,
a JWL50A.
8. Determine Coil Pressure Drop — For ethylene glycol
pressure drop calculation, the conversion factor
from Table 5 must be applied to design flow before
entering Table 4. 75 GPM x 1.05 = 79 GPM.
The coil pressure drop for 79 GPM is 2.4 PSI

CAPACITY CONTROLS
Dual Fan Motors—The dual fan motor package is available as
a proven energy saving capacity control option. It consists of
furnishing a high efficiency motor, a 1200 RPM, low speed motor,
two sets of drives and belts, extended fan shaft and motor bases
on opposite sides of the blower. A UL control-starter panel is
available as a completely wired package for one point connection.
Variable Speed Drive—A Variable Speed Drive automatically
minimize the tower’s noise level during periods of reduced load
and/or reduced ambient temperature without sacrificing the
system’s ability to maintain a constant cold water temperature. This
is a relatively inexpensive solution, and can pay for itself quickly in
reduced energy costs.
Electric Damper Controls—An electric damper control package
is available as an accessory for modulating the internal damper
system. A proportional solid state actuator is factory mounted
below the fan scroll and attached to the damper shaft by
connecting linkage. A sensing bulb connected to the actuator by
a capillary tube is normally mounted in the unit pan water basin
for monitoring the system. However, when specified, a pressure
control may be supplied for field mounting to allow direct head
pressure control. An end switch located inside the motor actuator
may be adjusted to cycle the fan motor on for pressure rise and off
when dampers close.
COIL CASING INSULATION
In order to further reduce the heat loss from the unit coil, insulation
factory installed on exterior coil panels is available. A protective
coat of paint is applied to the insulation for protection from the
weather elements.
POSITIVE CLOSURE DAMPERS
Many times during unit shutdown with fan and pump off, it is
desirable to conserve the amount of heat loss from the process
fluid. For those applications, closure dampers are available for this
installation at the air discharge of the fluid cooler. The damper
package is designed to prevent convective air flow through the
idle unit thus minimizing the heat loss. Installation of the closure
dampers requires all wiring to be completed in the field. An electric
actuator is factory mounted, however controls are to be supplied by
others. The damper actuator should be wired into the field control
system to allow the dampers to fully open when the fan cycles on
and close when the fan cycles off. The actuator requires a 115V
power supply
ELECTRONIC WATER LEVEL CONTROL
The electronic water level control package provides a constant
and accurate means of monitoring water level in the unit. For this
reason, it is often recommended for those installations which
require year round operation in low ambient conditions.
The complete package includes an electric float switch with stilling
chamber which is factory installed in the pan section of the unit.
An electric solenoid valve for water make-up is shipped loose for
remote installation. All wiring must be provided in the field by
others.
PUMP STRAINER
Pump intake extension and a cleanable non-ferrous pump strainer in
an easy access location is available.
MODIFICATIONS TO WATER DISTRIBUTION SYSTEM
Various package are available to provide manual or automatic
change-over as a backup system in the event of a spray pump
failure
PAN HEATER
The use of a remote sump tank located indoors is a common form
of pan water freeze protection for evaporative cooling equipment.
However, for those installations which will not allow this type of
system, freeze protection may be provided by electric immersion
heaters or steam or hot water coils installed in the pan.
The electric heater package consists of immersion heaters installed
in the pan to provide efficient even heat distribution. Standard
heaters are selected to provide approximately 40°F pan water at
-10°F ambient temperature. A low water cutout switch is supplied
to prevent heater operation when the elements are not completely
submerged. The heaters are monitored by a sump thermostat
with remote sensing bulb located in the pan water. All heaters and
controls are factory installed for field wiring by others.
NOTE: Pan heater packages are designed to prevent pan water
freezing during unit shutdown with fans and pump idle.
CAPACITY BOOSTER COIL
A finned coil mounted on top of the eliminator section is available
primarily for applications with high entering fluid temperatures
or for applications where dry operation under low entering air
temperatures is anticipated. Copper tube with aluminum or copper
fin coils are available.
VIBRATION ISOLATORS
Spring type vibration isolator rails may be supplied for field
installation, most units will require an intermediate rigid steel
framework between the isolators and the base of the unit to
provide adequate structural support for the unit. Consult Recold
sales representative for recommendations on any vibration isolation
application.
STAINLESS STEEL CONSTRUCTION
300 stainless steel construction is offered as an option for sump
pan and upper casing panels.
