AKGTS provides the mating connectors only if the harness is purchased along with the units or if the mating connector part number is called out on the purchase order. Please refer to the Product Literature to determine the fan connector.
What is SCFM and how do I find out the maximum SCFM of the compressor cooler (CC Series)?
SCFM is a measure for air at standard temperature and pressure conditions. For more information, please refer to the link below. The maximum allowable SCFM is also mentioned on our compressor product brochure. AKG CC Series What is SCFM?
Can I operate/wire the fan in reverse direction to clean out the cooler?
Yes, but please consult AKGTS to check if the existing fan unit is capable of running in reverse and to know more about fan reversal timings.
Note: AKGTS reserves the right to void the warranty if there are cooler/fan failures due to fan reversals without consulting with factory prior to installation.
Can I install my unit upside down so that outlet becomes inlet and change the cooler orientation to suit my needs?
The inlet and outlet connections are completely reversible for non-bypass coolers only. If your cooler has an integrated bypass feature, the inlet and outlet connections cannot be reversed. Please consult factory for more information. The cooler assembly can be mounted in any direction as long as they are properly supported/balanced using mounting brackets and feet to bear the static/dynamic load conditions and accelerations. Use of vibration mounts/isolators are highly recommended to avoid cracks, failures etc.
Can I install my unit outdoors?
Yes, AKGTS coolers are suitable to be installed outside. However, certain precautions have to be taken into consideration during installation. Cooler installation near obstacles should be avoided. Ambient conditions need to be taken into account and precautions should be taken to prevent dust/debris entering the air fins. Improper cleaning of external air fins may lead to decreased performance and could overheat the hydraulic system.
Are the motors dual rated?
The Class 1 Div. 2 Three phase, Explosion proof – Three phase and single phase are all dual rated. Please consult factory to know more about the standard single phase and three phase dual rating options. Please be aware that the motor rpm is reduced by 1/6 for 50Hz frequency.
Note: The standard 3 phase motors do not meet IE2 and IE3 standards.
Is the fan metal or plastic?
All the standard fans that AKGTS supplies are made out of PAG (Glass reinforced PolyAmide) or PPG (Glass reinforced PolyPropylene). Temperature ranges from -30C to +90C (-22F to +194F) for a PPG fan and -40C to +120C (-40F to +248F) for a PAG material fan. Please consult factory for more information.
How do I wire the motor if I want it to run the fan in reverse direction?
The motor polarities can be changed to make the fan run in the opposite direction. Please consult factory to check if the fans can be reversed to avoid any other issues in the field before changing the motor polarities as it depends on the type of application/type of fan used. For AC motor wiring, the information can be found on the motor nameplate or on the motor supplier’s website. Please consult factory for motor datasheets.
Where can I get CAD (3D) models and drawings?
If you have an existing account with AKGTS, please contact our sales department or refer to the distributor login page to get the STEP models/drawings. Please allow up to 24-48 hours for CAD models/drawing requests. If you are not an existing customer, please contact your authorized fluid power distributor for CAD models and drawings for immediate needs.
Why is my A.C. electric motor hot?
There could be a couple of reasons that causes overheating in electric motors
- Higher working/ambient temperature – In these cases, the application is working at a higher temperature range or installed outside where it is too hot, so re-tagging the nameplate to 50 deg C would eliminate the issue.
- Higher amp draw – When the ambient temperature is lower during winter conditions, the air density increases and the fan consumes more horsepower to pull air through the cooler. Using a VFD or controlling the fan during lower ambient conditions could avoid that problem. Also, this should be taken into account while sizing the heat exchanger so the motor can be sized accordingly taking the safety factor into account.
- Improper supply voltage/current – Sometimes, the A.C. motor supply voltage constantly varies and that causes the windings to get hot so please check the amp draw on all three wires, voltage between all three wires and voltage to ground.
Note: Voltage should be checked at both no load and full conditions
I’m using a D.C. fan drive, why is my amp draw higher?
There are a couple of reasons why the amp draw could be more:
- High working temperature
- Low ambient temperature
- Improper supply voltage/poor connection/ improper wire thickness
- Hot air re-circulation (improper cooler installation with no free airflow)
What type of fuse and what is the recommended fuse value for a D.C. fan?
A maxi type fuse is recommended on the brushed/brushless fan drive. Different diameter fans consume different amp draw depending the on the type of motor used. Please refer to the mobile cooling product brochure for more information. Link: Mobile Cooling Product Brochure
Can I install my cooler next to a wall or obstruction?
No, unfortunately the exhaust air will recirculate if there is an obstruction near the cooler. This will affect the heat exchanger performance and overheat the oil/hot media inside the cooler. It may also increase the amp draw on the fans which will lead to a decrease in product life expectancy. AKG recommends at least 1 fan diameter distance on the exhaust side to avoid hot air re-circulation.
Can I install my cooler inside an enclosure and seal it well to reduce the fan noise and prevent dust/debris from entering the cooler?
No, the cooler should not be installed in a fully closed enclosure. The unit needs free airflow across the cooler for optimal performance.
Can city water be used as a hot media on the heat exchangers?
AKGTS doesn’t recommend city water to be used as a hot media. Any media that falls within the 6.5-8.5 pH range is safe and compatible with Aluminum. Other types of media should be consulted with factory before use. It is the responsibly of the end-user to make sure the media used is compatible with Aluminum to avoid any form of corrosion. Please see below for the minimum required media characteristics.
- Appearance: Colorless, clear
- Sediments: None
- PH value: 6.5 to 8.5
- Total water hardness: <3.6 mmol/l (sum of alkaline earth metals)
- Chloride content: <100 mg/l Sulphate <100mg/l
Demineralization is very important and AKGTS recommends a minimum of 40-60% of the coolant concentration to be glycol in the system or any form of corrosion inhibitor for water based media/application. For other concentrations, please consult factory.
How do I wire the temperature switch or PWM controller?
The PWM controller wiring diagram is provided in the DCSB (brushless fan drive) brochure. AKGTS offers a plug and play harness kit that comes with a preinstalled fuse, mating connectors, splice box that saves installation time. Please refer to the DCSB brochure link for more information. For the D.C. brushed temperature switch option, please make sure to use a 5A amp fuse to protect the micro switch which is present inside the temperature switch. Please refer to the Brushed DC Fan Wiring Information.
Where is the digital screen to adjust the temperature on my temperature switch?
AKGTS discontinued all the TCP’s as of 2018 and we no longer support them. We do offer a replacement but they do not have a screen as it is a nonadjustable temperature controller. We offer 4 options – TC-115, TC-140, TC155-WL and TC-140-WL.
