STANDARD FEATURES:
Colmac AFV/AFH model air-cooled fluid coolers are designed to provide cooling of Water, Ethylene Glycol/Water andPropylene Glycol/Water mixtures in a variety of closed-loop applications. Closed-loop cooling eliminates the cost of fluidtreatment usually associated with the use of cooling towers.
• Wide range of models and capacities - 33 models.
• Corrosion resistant construction - Mill galvanized housing, powder coated steel fan guards, aluminum fan bladeson 3/4 Hp models, galvanized steel fan blades on 1 & 2 Hp models. Low speed, fully guarded fans for quietoperation.
• Built-in lifting eyes, and easy-to-install legs, make rigging and installation fast.
• Low noise, 850 RPM fans, on 1 & 2 Hp models.
• Compartmented fans to prevent short circuiting of air during fan cycling.
• Units designed for efficient fan cycle control.
• Versatile cabinet design for vertical or horizontal airflow.
• Coil is made of 1/2" dia seamless copper tubes,and high efficiency aluminum plate fins, with self-spacing collars.
• Exclusive Colmac “Full Floating Core” coil support system eliminates tubesheet leaks by shifting support of thecoil core from tubes to fins. Special “Wear Guards” allow expansion and contraction of fins and tubes withoutchafing or wearing of tubes, or fins.
• Heavy duty rigid foot-mounted direct drive fan motors with moisture protected rainshields (slingers) are internallyprotected single or three phase on models 62 thru 384 (3/4 Hp), internally protected three phase only on models119 thru 1271 (1 Hp), and three phase externally protected only on models 1425 thru 1625 (2 Hp). Motors are ratedfor 150°F maximum air temperature over the motor.
• Weatherproof electrical enclosure features single point field wiring, and is easily accessible for fast installation.
OPTIONS:
• Copper fins, or Polycoat Fins for corrosion resistance. • Baked phenolic coating available
• Stainless or galvanized steel fan blades or cast aluminum. • UL 508 listed electrical panels
• Stainless steel housing. • CSA listing available
• Factory mounted and wired fused disconnect.
• Factory wired fan cycle/fan speed control.
• Customer specified control systems.

Notes: 1. Weight of Liquid is calculated as follows:
Wt. Liquid (lbs) = Internal Vol. (cu. ft.) x Liquid Density(lbs/cu ft)
2. Operating Weight = Dry Weight + Weight Liquid
3. Units having finned length up to 216" use 1/2 x 0.016 copper tubes.Units having finned length of 270" use 1/2 x 0.025 copper tubes.

OPERATION WITH 50 Hz POWER
COLMAC AFV and AFH fluid coolers are designed to operate with either 60 Hz, or 50 Hz supply power. Cooling capacityfor 50 Hz operation will be the same as capacity for 60 Hz operation, since COLMAC uses fan blades matched to the 50Hz rotational speed of 950 RPM.
Motor horsepower on most models will be different, however. The 60 Hz, 3/4 HP motors will be replaced with 1.0 HP motors,and 60 Hz, 1.0 HP motors will be replaced with 1.5 HP motors for 50 Hz operation.
50 Hz FAN SPEED/SOUND LEVEL:
Operation of fluid coolers at 50 Hz will change the rotational speed of the fans. All fans will turn at 950 RPM. The 24 in.dia. fans will turn slower than those used for 60 Hz operation, and will run quieter. The 30 and 36 in. dia. fans will turn fasterthan those used for 60 Hz operation and will be somewhat louder. Fan and tip speeds, and sound levels for 60 Hz and 50Hz are shown in tables 3 and 4.

SELECTION PROCEDURE:
The selection of a COLMAC AFV/AFH fluid cooler is mostly graphical and is easy to make.
Glossary of Terms
ACF = Altitude Correction Factor (Fig. 9)CCF = Capacity Corr. Factor, Fluid Mixture (Fig. 6)EAT = Entering Air Temp.EFT = Entering Fluid Temp.FF = Flow factor (Figs. 10 thru 16)FHF = Fluid Heat Factor (Fig. 5)GPM = Gallons per MinuteLAT = Leaving Air Temp.LFT = Leaving Fluid Temp.LF = Length factor (Figs. 10 thru 16)MBH = BTUH x 1000ΔPfluid= Fluid Pressure Drop, psi (Fig. 7)PDF = Pressure Drop Factor (Fig. 8)
Step 1. Calculate Avg Fluid Temp., AFT.AFT = (EFT + LFT) / 2
Step 2. Calculate Fluid ΔT.ΔT = EFT - LFT
Step 3. Calculate temperature difference, TDTD = EFT - EAT
Step 4. Find Fluid Heat Factor, FHF, (Fig. 5).
Step 5. Calculate MBH required per degree of temperature difference.MBH / TD = (GPM x ΔT x FHF) / TD
Step 6. Correct MBH / TD with CCF (Fig. 6) and ACF (Fig. 9).MBH / TD = (MBH / TD) x CCF x ACF
Step 7. Choose Model, using GPM and MBH / TD in Figs. 10 thru 16. ** (Use Models whose performance curves fall on, or above MBH / TD)
Step 8. Find Fluid Pressure Drop:- Using GPM, find FF and LF from Figure used in step 7.- Using FF and LF, go to Fig. 7, to find ΔPfluid.
Step 9. Correct Fluid Pressure Drop with PDF (Fig. 8).ΔPfluid = ΔPfluid x PDF
Step 10. (Optional) Unit capacity can be approximated by the following method:
MBH/TD (Curve value) MBH actual = ————————————————————— x TD CCF x ACF
Page 12
EXAMPLE
1. AFT = (125 + 115.5) / 2AFT = 120.3°F Given: % Glycol = 30% Ethylene Glycol
GPM = 802. ΔT = 125 - 115.5 EFT = 125°F
ΔT = 9.5°F LFT = 115.5°FEAT = 95°F
3. TD = 125 - 95 Alt.= 2,000 ftTD = 30°F
4. From Fig. 5, we see that FHF = 0.466
5. Calculate MBH / TD = (GPM x ΔT x FHF) / TDMBH/TD = (80 x 9.5 x 0.466) / 30MBH/TD = 11.8
6. Correcting capacity for 30% Eth. Gly. and 2,000 ft alt.using CCF (Fig. 6) and ACF (Fig. 9):
CCF = 1.002 and ACF = 1.04
MBH/TD = 11.8 x 1.002 x 1.04MBH/TD = 12.3
7. Looking at Fig. 11, using 80 GPM and 12.3 MBH/TD:
a. Choose AFV-254 At 80 GPM, it’s performance is 12.9 MBH/TD, which is greater than 12.3
b. Using diagrams in Fig. 11 for Flow Factor (above) and Length Factor, (side):for AFV-254 (Fig. 11): FF = 3.33
LF = 648
8. Looking at Fig. 7, using 80 GPM, FF = 3.33 and LF = 648
ΔPfluid = 7.5
9. Correct for ΔPfluid for 30% Eth. Gly mixture at 120°f using Fig. 8: PDF = 1.175
ΔPfluid = ΔPfluid x PDFΔPfluid = 1.175 x 7.5
ΔPfluid = 8.8 psi
10. Actual Unit Capacity at 80 GPM, 120°F AFT, 30°TD, and 30% Ethylene glycol, is approximately:
MBH / TD 12.9 MBH/ T̄D MBH actual = ————————————— x TD = ——————————————— x 30
CCF X ACF 1.002 x 1.04
MBH actual = 371.37
Page 13
Notes:
1. The selection procedure is optimized for system performance while keeping fluid pressure drops below a reasonablemaximum (less than 12 PSI). If calculated ΔPfluid is greater than that desired, it is possible to make another selectionon COLMAC’s CoilPRO III software, using a “Hot Water/Sensible Cooling” coil, or have COLMAC’s Factory Salespeople assist in making another circuiting selection.
2. Flow Factors greater than 3.5 are not recommended, and are not represented in Figs. 10 thru 16.
3. See Table 5. for suggested inlet/outlet pipe sizing.

OPTIONAL FAN CONTROL
COLMAC offers FC Fan Cycling and MS Modulated Speed control packages to compliment the selection of any fluid cooler.Such controls may be used to maintain the desired Leaving Fluid Temperature regardless of operating conditions, orseasons.
FC fan cycling controls will stop rotation of one or more fans in incremental stages to maintain temperature.
MS controls will slow rotation of one or more fans to maintain temperature. On multiple fan models, a combination ofModulation and Cycling is used. If the fluid temperature falls below the point at which the Modulating fan(s) can maintaintemperature, one or more additional fans will be shut off and the remaining Modulating fans will gain more speed until thedesired fluid temperature is reached.
Note: Because MS controls affect motor winding temperature, please consult the Factory for application information andpricing.
