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.

Connection quantity is total of in and out connections Recold / JW Series Fluid Cooler / Freeze Protection 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.

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.

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 ETHYLENE GLYCOL 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: Select a unit to cool 75 GPM of 40% by volume ethylene glycol from 107°F to 85°F with 78°F wet bulb. 102°F - 90°F = 12°F Range 1. Determine Range: 2. Determine Approach: 107°F - 85°F = 22°F Range 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. 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 DEFINITIONS Range: the difference between the entering and leaving water temperatures (WT in – WT out). Approach: the difference between the leaving water temperature and the web bulb temperature (WT out – WB). Load BTUH = GPM x 500 x Sp. Gr. x Sp. Ht. x (T1 – T2) where Sp. Gr. = specific gravity at average temperature Sp. Ht. = specific heat at average temperature T1 = entering temperature T2 = leaving temperature Recold / JW Series Fluid Cooler / Load Factors 8 TABLE NO. 2 60° WET BULB 4.8 4.5 4.3 4.0 3.8 3.6 3.5 3.3

Recold / JW Series Fluid Cooler / Accessories 12 CAPACITY CONTROLS PUMP STRAINER 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. Pump intake extension and a cleanable non-ferrous pump strainer in an easy access location is available. 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 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. 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.
