PERFORMANCE

SizingThe performance curves provided are for petroleum oil at 63 ssu viscosity.However, fluids with characteristics other than the above mentioned may beused by applying a correction factor.

Heat LoadIf the heat load is unknown, a horsepower value can be calculated by firstdetermining the systems total potential. For a basic hydraulic system, it ishelpful to know whether the system is open loop (with a large reservoir) orclosed loop (normally on mobile equipment, with a very small reservoir).System potentials may be calculated quickly by using one of the twomethods below.

There are some system parameters that will be required to properlyaccomplish the sizing calculations. Without system parameters it isdifficult to determine the optimal heat exchanger size. Normally many ofthe system parameters can be found on hydraulic schematics or on tagslocated on the actual equipment. Following are some basic parametersthat you should try to acquire before attempting the sizing calculations.However, it is not necessary to have every parameter listed below.

• Main system flow rate (gpm) & operating pressure (psi).• Electric motor HP driving hydraulic pump (if more than one add up

the Hp for all).• Desired temperature (°F).• Fluid type (SAE 10, 20, 30, etc....).• Ambient air temperature (warmest day).• Desired fan drive (hydraulic, electric, 12-24V DC, etc...).• BTU's or HP to be cooled (normally given for lubrication systems).• Maximum pressure drop allowed through the heat exchanger.• Space available for heat exchanger (LxWxH).

Method 1Normally used for open loop circuits. Multiply the main hydraulic systemsElectric Motor Name plate Horsepower by a heat removal factor (normally30-50%).

Example: 50 HP motor x 0.3 = 15 HP heat load

Method 2Normally used when the HP input potential is unknown or for mobileapplications where diesel engines operate the entire system. Multiplysystem pressure by the flow rate of the main system divided by 1714 equals

system potential (HP). Multiply the system HP by a heat removal factor(Normally 25-35%). Note: In some closed loop systems only a portion of thetotal system flow is directed through the heat exchanger, this may affect thecooler selection process substantially. You may contact our factory foradditional technical assistance.

Example:

Determining Fs valueTo determine the proper size heat exchanger for your application, use thefollowing equation to first determine the (Fs) factor.

Fs =

Example:Heat load = 50 HPCv = 1.14 (SAE 20) determined from chart. [Located on page 4.]Desired operating temperature = 120 ºFAmbient air temp. = 100 ºF

Fs = = 7254

SelectionTo select a model, locate the flow rate (GPM) at the bottom of the flow vsFs graph. Proceed upward until the GPM flow rate intersects with thecalculated Fs. The curve closest above the intersection point will meet theseconditions.

Example: Fs = 7254 = Model = AOCS - 1505 - *GPM = 40PASSES = 2

Pressure differentialsDetermine the oil pressure drop from the curves as indicated. For viscositiesother than 63 ssu, multiply the actual indicated pressure drop for your GPMflow by the value shown in the pressure differential curve for your viscosityvalue.

Example: AOCS-1505 @ 40 gpm & 63 ssu -2 pass curve- Indicated pressure drop 5 psi (Approx) { 5 psi x 2.8Cp (for SAE-20 oil) } = 14.0 corrected psi

(2000 psi x 30 gpm) = [35 HP x .25] = 8.75 HP heat load _______________ 1714

{ heat load (HP) x 2545 x Cv } __________________________{ °F (oil leaving - air entering) }

{ 50 x 2545 x 1.14 } ________________{ 120 °F - 100 °F }

ELECTRICAL TEMPERATURE CONTROLLER WITH BULB WELL ASSEMBLY (for Air/Oil Coolers)

SPECIFICATIONS:A) Material: Copper

B) Power Limits:

1)For three phase motor operation, use only with a magnetic starter, 125 VA max. (VA =volts x amps)2)For pilot duty, 125 VA max.3)For direct connection to motor:

120v AC/8.0 amps max 230v AC/5.1 amps max277v AC/4.2 amps max 460v AC/2.0 amps max

4)Temperature operating range: 55°F to 175°F.

APPLICATIONS (Temperature Controller)The TC511 temperature controllers are designed to control the tempera-

ture of air or liquids in ducts, pipes, tanks, and boilers. Typical uses includecontrol of dampers and valves in heating, cooling, or heating-cooling sys-tems. The TC511 has 1 spdt switch. It makes or breaks a circuit on a changein temperature at the sensing bulb. Fast response models with adjustabledifferential are available for duct installation. They respond approximately 4times faster than standard models.

INSTALLATIONWhen installing this product:1. Read instructions carefully. Failure to follow the instructions could

damage the product or cause a hazardous condition.2. Check the ratings given in the instructions and on the product to make

sure the product is suitable for your application.3. Installer must be a trained, experienced service technician.4. After installation is complete, check out product operation as provided

in the instructions.

LOCATION AND MOUNTING.The controller may be installed in any convenient position. Mount it

with 3 screws through the slotted holes in the back of the case. Be sure toconsider the length of the capillary before mounting the controller.

Install the sensing element where it is exposed to the average tempera-ture of the controlled medium. The sensing bulb may be directly im-mersed or mounted in a well. Fast response models must use the capillaryholder furnished with the device. The remote sensing bulb of standardmodels should be held in place with a capillary holder, immersion well, orcompression fitting. Sharp bends or kinks in the capillary tubing affect theefficiency of the controller and must be avoided. Excess capillary shouldbe carefully coiled and left directly beneath the controller.NOTE: When pressure fittings are used in areas of vibration (suchas pipe lines) the bulb must be adequately supported.

OPERATIONAs the temperature of the controlled medium falls belowthe set point less differential, the TC511 switch makesterminal R to B and energizes a normally closesolenoid valve to provide heat. In cooling applica-tions, the TC511 makes terminal R to W asthe temperature rises above the set point,energizing cooling equipment.

Receiving:

a) Inspect unit for shipping damage before uncrating. Indicate alldamages to the trucking firms' delivery person, and mark it onthe receiving bill before accepting the freight. Make sure that thecore and fan are not damaged. Rotate the fan blade to make surethat it moves freely. Since the warranty is based upon the unitdate code located on the model identification tag, removal or ma-nipulation of the identification tag will void the manufactureswarranty.

b) When handling AOCS heat exchangers, special care should betaken to avoid damage to the core and fan. All units are shippedwith wood skids for easy forklift handling. Lifting holes are lo-cated on the top-sides of the unit.

c) AOCS models are shipped with one coat of factory appliedgray enamel semigloss paint. A finish coat of paint should be ap-plied to all steel surfaces unless storage is indoors. Caution; DoNot paint the aluminum core fins as this could impair the overallperformance. The units are washed internally with a mineral spirit/oil solution to remove debris, and for temporary rust protection.If storage will be longer than 60 days additional rust preventativeshould be added to the interior of the core. All openings are sealedwith plastic pipe plugs prior to shipment. Check to make surethese are in place prior to storage.

Installation:

a) Plan your installation in a location where there are no obstruc-tions to the inlet or discharge airflow path. If the unit is to beinstalled in a wall, ample room ventilation should be provided.Duct work or additional cooling cores added to the housing of thecooler or in front of the cooler would increase the static pressurerequirement of the fan motor thus increasing the horsepower re-

quirement of the motor. Ducting should be slightly larger that thecore area with long radius turns to prevent added static pressure.Prevailing winds should be considered before installing. Windsblowing heated air back into the cooler could cause loss of cool-ing especially on hot summer days.

b) We recommend that flexible hose or nonrigid plumbing be usedto reduce the risk of failure due to thermal expansion of the coreand hydraulic vibration. Hydraulic carrying lines should be sizedto handle the appropriate flow and to meet system pressure droprequirements based upon the systems parameters, and not basedupon the units supply and return connection size. We suggest thatpreventative filtration should be located ahead of the cooler tocatch any scale or sludge for the system before it enters the cooler.

The standard AOCS oil coolers are built with a ServiceableCore™, and carry a 200-PSI maximum working pressure at 300°Fmaximum temperature. We suggest that a three-way thermal by-pass valve or a direct acting low-pressure (60psi) relief valve beinstalled at the inlet to the cooler to protect it in cold weatherenvironments. Units should not be placed into a corrosive envi-ronment, as rapid deterioration of all exposed components willoccur resulting in shortened life or failure. For external corrosiveenvironments please contact our factory prior to installation.

c) Electric motors should be connected only to a supply power ofthe same characteristics as stamped on the electric motor name-plate. Prior to starting verify that the motor and fan spin freely.Check carefully that the fan turns in the correct motor rotationdirection. Failure to operate the fan in the proper direction couldreduce performance and cause serious damage to the heat ex-changer.

d) It is important to apply the catalog recommended flow rate forthe hydraulic motor that corresponds with the specific model be-

ing used. The proper flow rate and direction to the hydraulic mo-tor are critical to ensure fan direction and RPM. Exceeding therecommended RPM could result in fan failure and cause severedamage to the heat exchanger.

Maintenance:

a) Inspect the heat exchanger and motor for loosened bolts, con-nections, rust spots, corrosion, fin core clogging, and external fluidleakage.

b) Heat exchangers operating in dirty or dusty environments willoften need to have the fins of the core cleaned. Clogged fins shouldbe cleaned by carefully brushing the fins and tubes with water ora light solvent. Use compressed air to blow and loose debris outof the fins. Rinse core with a light degreasing soap and waterbefore reinstalling.

c) Dirt, oil, and grease should be removed from the electric mo-tor, fan, and fan guards. Rusty surfaces should be cleaned and re-coated with paint.

d) In most cases with clean hydraulic system oils it will not benecessary to flush the interior of the core. In circumstances wherethe quality of hydraulic fluid is in question, the core should bedisconnected and flushed on a yearly basis with a clean flushingoil/solvent to remove any sludge that has been deposited. If stub-born sludge or it is determined that performance has been sub-stantially reduced, the manifold covers may be unbolted and theinternals thoroughly inspected or cleaned. For severe cases wherethe tubes are plugged and cannot be flushed clean with solvent,the turbulators can be removed and cleaned or replaced as de-sired (consult factory). We suggest a filter be used at the coolerinlet to reduce the fouling of the tubes.

e) For severe cases where the tubes are plugged and cannot beflushed clean with solvent. On units containing the ServiceableCore™, the manifold covers can be removed by simply removingthe cover bolts. Turbulators can then be extracted from the tubes,cleaned or replaced as desired. We suggest a filter to be used atthe cooler inlet to reduce the fouling of the tubes.

f) Most low horsepower electric motors do not require lubrica-tion. However, many larger HP motor bearings must be lubri-cated with good quality grease once per year, or every 6-9 monthsfor severe duty. TEFC air ventilation slots should be cleaned regu-larly to allow air to cool the motor. To maintain the motor prop-erly, follow the motor manufacturers recommendations for main-tenance and lubrication.

g) Fan connector bushing tightness should be checked and re-tightened if required after the first 100 operating hours of use.Fan blades should be cleaned and inspected for tightness on ayearly basis. When handling a fan blade care must be taken toavoid bending or striking any of the blades. The fan blades arefactory balanced and will not operate properly if bent or unbal-anced. Damaged fan blades can cause vibration and severe dam-age to the heat exchanger and drive motor.

h) American Industrial has gone to great lengths to provide com-ponents that are interchangeable and repairable. If your unit getsdamaged, chances are that you can initiate the repairs in yourown shop. Most parts of AOCS heat exchanger are made of heavygauge metals that can be bent back into position after externaldamage. The core is Serviceable Core™, making repairs to bro-ken tubes possible simply by removing the manifold covers andinserting lead plugs into the damaged tube(s). In most circum-stances you will only need to purchase an additional gasket setand bolts. Please consult American Industrial for specific repairdetails.
