Standard Motor(s) = 1600 RPM, Custom Frame, Equipped with Thermal Overload. Optional Motor(s) = 1725 RPM, Nema 48 Frame, No Thermal Overload. Published electrical ratings are approximate, 

and may vary because of motor brand. Actual ratings are on motor nameplate. *3 phase motors available in 50Hz. Reduce performance by 10%. (1) Air inlet to motor must be regulated to this 

pressure. (2) CFM (Free Air) consumption of the air motor. Lubrication = one drop of oil for every 50-75 CFM (1.42-2.04 CMM) of air going through the motor. Use detergent SAE #10 oil. Filter, regulator 

and lubricators for the air motors are required, but not included.

Air Belt Guard 


No fan motor required via mounting to 

compressor belt guard. These coolers, built 

from either round cooper tube & fin or bar 

& plate brazed aluminum construction, 

allow the use of free air flow from the 

belt guard on reciprocating compressors. 

Compact and light weight, the Belt Guard 

Series is offered in seven models with 

capacities from 20-100 SCFM (.57-2.8 KW).

Air AHP/AHPH 


Our highest performing aftercooler, the AHP and AHPH are built from 

high-performance plate & bar aluminum construction. Energy efficient, 

durable and flexible mounting in horizontal or vertical configurations. 

The finish is a rugged black powder coating. Nine models with 

flow capacities from 125-4800 SCFM (3.5-135.9 SCMM) and used 

on compressors from 60-700 HP (44.7-522 KW). Fan options include 

electrical TEFC and air motor drive. The legs ship detached to 

allow the cooler to be installed in numerous configurations.

Industrial AOL 

Air Cooled Oil Cooler 

Apply this cooler for rotary screw, compressor lube or 

gear box oils. The AOL Series utilizes forced ambient air 

to cool compressor lube oil and is an excellent choice 

for demanding oil cooler requirements or for converting 

medium to large volume water cooled compressors to air 

cooled. Built from rugged brazed aluminum bar & plate 

and designed with detachable legs for ease of mounting 

in alternate locations. Nine models available with oil flow 

capacities from 15-120 GPM (57-454 LPM) and used on 

compressors from 35-400 HP (26.1-298.3 KW).

water Cooled Aftercoolers 

High performance aftercooler utilizing supplied water to cool 

compressed gas or air from piston compressors. Constructed 

using round copper tubes, which allow the air side tube bundle 

to be easily cleaned and maintained. Brass hub and shell 

construction protect against galvanic corrosion. Great for 

piston or screw style compressors. Ten models with flow 

capacities from 40-3170 SCFM (1.1-89.8 SCMM).

*Based on ambient air at 60°F (15°C), 14.7 PSIA, and 50% relative humidity. Compressed air cooled to within 15°F (8°C ) of inlet water 

temperature. Water flow rate 3 GPM per 100 SCFM (4 LPM per SCMM) air flow. For single stage compressor type, 300°F (149°C ) inlet, 

use 2-stage SCFM capacities with a 15% reduction. 

SELECTION EXAMPLE 

Specified 

Two stage compressor with a 340 SCFM 

(9.63 SCMM) air delivery at 100 PSIG (7 BAR) 

and a 250°F (121°C) discharge temperature. 

Maximum allowable pressure drop is 2 PSI 

(.14 BAR). Water flow rate to be determined. 

Solution 

STEP 1 From the 2-stage compressor 

column select model 

AB-1006-B6-0 with 440 SCFM 

capacity. 

STEP 2 To determine P: Read column to 

right of SCFM capacity selected. 

P = 0.3 PSI (.02 BAR) 

STEP 3 

Water flow rate required 

340 SCFM x .03 = 10.2 GPM 

(9.63 SCMM x 4 = 38.6 LPM)

water Cooled oil cooler/Aftercoolers 

Shell & Tube style air/oil coolers offer the widest variety of options for cooling 

compressor lube oil or air utilizing water. This model is an excellent choice where seawater or 

corrosive fluids are in contact with cooler internals. For new applications, interchange or ASME 

codes are required. Seventeen models with air flow capacities from 75-1500 SCFM (2.12-42.48 

SCMM) or oil flow from 7-105 GPM (27-397 LPM) and heat rejection from 14-281 HP (10.4-209.5 KW).

INFORMATION 

Technical Information 

Recommended Typical Installation 

n Support piping as needed. Flexible connectors must be properly installed 

to validate warranty. 

n Coolers should not operate in ambient temperatures below 35°F (1°C). 

Consult factory for recommendations. 

n The fan cannot be cycled. 

n AHP coolers operated outdoors must be protected from weather. Consult 

factory for recommendations. 

n If ductwork or additional static resistance is added to the cooler airstream, 

an auxiliary air mover may be required. 

Maintenance 

n Periodic cleaning of the fins with compressed air is needed to remove the 

accumulation of dirt and dust. 

n Check the automatic drain on the separator (not included) periodically. 

n If the inside of the tubes need to be cleaned of oil and carbon, use a 

chlorinated solvent. Do not use strong solvents. Do not use acids or 

caustic cleaners.

Compressed Air Aftercoolers 

Aftercoolers are heat exchangers that cool the discharge from 

a compressor. The media used is air & water and is the most 

effective way to segregate the moisture and compressed air. 

Aftercoolers control the amount of water vapor in a compressed 

air system via condensing the water vapor into a liquid form. In 

nearly all industries with manufacturing or service equipment, 

liquid water can cause permanent damage when using 

compressed air. 

An aftercooler is required to ensure the proper function of 

pneumatic or air handling devices. The two methods utilized 

are either air cooled or water cooled aftercooling. 

Typically aftercoolers are integrated into the OE compressor 

or may stand alone and located somewhere downstream of 

the compressor. 

Moisture separators and drain valves are mounted into a pipeline 

fitted with water cooled aftercoolers or a heat exchanger. They 

extract the majority of water from the compressed air as it passes 

through the piped components. The moisture separator spins 

the fluid by using centrifugal force to separate out the moisture 

and solids from the compressed air. The water is allowed to exit 

via a bottom drain. An air cooled heat exchanger uses available 

ambient air to cool the hot compressed air. Most air cooled heat 

exchangers use a fan that produces forced air. The fan is driven 

by an air or electric motor which forces the ambient air over the 

cooler, removing the heat from the compressed air. 


Thermal Transfer Products models of air cooled aftercoolers 

provide economical cooling by utilizing available ambient air 

to cool the hot compressed air from an air compressor. When 

properly sized, an aftercooler can remove up to 60% of the water 

in compressor air. 

Owing to the compressor type, discharge air is approximately 

150-350˚F (66-177˚C). During the cooling of the compressed air, 

nearly 60% of the water vapor present will condense into liquid 

water. A line installed separator will immediately remove the water 

from the system. Air cooled aftercoolers, when applied properly, 

can cool the hot compressed air between 5-20˚F (3-11˚C) of the 

available ambient air temperature. Normally wasted heat can be 

reclaimed and recirculated by the aftercooler. 


Thermal Transfer water cooled aftercoolers, when combined with 

a water separator, are a significant means of removing unwanted 

water moisture from compressed air. Field studies prove that 

a properly sized and installed aftercooler and liquid separator 

will effectively maintain worry free operation of compressed 

air equipment. When the downstream compressed air line 

temperature is lowered by applying a correctly sized water 

cooled aftercooler, more than 70% of the entrained water vapor 

will condense to liquid form. This liquid is easily removed by a 

moisture separator. 

Due to mechanical friction created from moving parts, 

compressors generate significant heat. To promote long 

component life and efficient operation, all moving parts must 

be lubricated. Thermal Transfer Products compressor coolers 

supply cooled oil to compressor operation, including all 

bearing and friction points. When heat circulates throughout 

compressor internals, heat is transferred to the oil and must 

subsequently be cooled via a heat exchanger.
