kaeser air compressor overheating shutting off ,is there a specific volume of air that needs to inlet and exhaust.


Its installed in a closed room.

There are a number of reasons why an air compressor will overheat.

I suppose it could be the shortage of intake air making the compressor work too hard, or lack of air circulation not allowing natural compressor cooling to take place. Try running the compressor with the compressor room door open to see if it makes any difference.

It is more likely that it is compressor related, and I would be looking into the air end as a possible heat source.

You don't provide any details of your air compressor (model / HP) so I cannot even check for technical documents about your problem.

Other visitors will comment on this I hope, but I expect that you probably will need assistance from Kaeser to help you, wherever you are in the world.

Cheers,

Bill

What other info will you need off our BSD 60 to help trouble shoot. The room has all the fresh air it can get , two 5x8 doors are open and there is a fan charging the space with fresh air. The system works ok when I bypass the desicant dryer , once I put the dryer in the loop the temp rises and the units have a hard time meeting idle pressure, builds to 144psi and continues to build heat until it shuts down. Idle pressure is set for 145 psi.

BDS 60 overheating problem
by: City Recycling

We have 2- BSD 60 compressors with a desicant dryer system. Our room is well ventilated radiators are blown clean daily. Just serviced and we are still having an overheating problem, the continues to rise little by little until it shuts down and the secondary compressor kicks in and that does the same..Where should I be looking to solve this overheating issue.

dirty cooler or bad thermostat valve
by: Anonymous

first: check if the cooler is dirty. If it's tidy, run the compressor, the temperature should raise to about 80-85 degrees celsius before the thermostat opens. Hold your hand on the cooler and you should feel it upheat distinctly as the thermostat valve opens, the temperature should decrease to about 70-80 degrees celsius.
If the temperature doesnt decrease, and the cooler's not getting destinctly heated, my guess is that you need to swap thermostat, kaeser original number should be 7.2013.0. But first of all, do as Bill said, check your ventilation. /kaeser mechanic in scandinavia.

More info
by: Carls421

I would be happy to help, but like Bill says, you would need to supply more details, there are hundreds of different types of Kaesar compressors out there, I do have lots of manuals here as I used to work for a Kaesar distributor (They are mainly Screw manuals) but nevertheless. More info would be good

Thanks for the kind offer. Let's hope the original poster provides more info for us both.

Code 5 - Kaeser air compressor shutting down?

by BRIAN
(MED HAT AB)

MY AIR COMPRESSOR SHOWS CODE 5 AND SHUTS DOWN RIGHT AFTER START UP. IT IS TELLING ME THERE IS SOMETHING WRONG WITH THE DRYER. I CLEANED ALL FILTERS.
___________________
Brian, I don't have the compressor or the manual. I would expect that the manual would identify the remedial action for any maintenance code.

Anyone else know what Code 5 for a Kaeser is and how to correct the compressor fault?

Consider emailing them directly:

info.canada@kaeser.com

Cheers and I hope someone with this Kaeser air compressor will comment here for you.

clockwise!
by: Anonymous

the brass bolt mentioned before, on the heat gas bypass valve, should be turned clockwise to warm up the dryer, not counter-clockwise as i wrote before.

code 5
by: Anonymous

Check the gauge for the refrigeration dryer, it should be on the green. If it's on blue, it is frozen and if its on the red it's too hot. Check if there is a high internal pressure switch thingy in the dryer, it's a little black thing with a blue reset button on it.

If its running blue on the gauge, you have to adjust the heat gas bypass valve, a square-shaped brass thing with a big bolt and a nut on it. Loosen the nut and screw the bolt counter-clockwise (not too much, about 1/4 turn at a time).

If the dryer seems OK, check your wiring diagram, i think the same wire that shuts down the dryer passes through the emergency stop putton for example. I've replaced the switches on the back of the button on two different compressors that gave code 5 alarm. /Kaeser mechanic in scandinavia

Sigma Controller?
by: Carls421

Hi,
I am guessing you have the Sigma controller Basic?

Code 5 is indeed a problem with the Refrigeration dryer, you need to (if you havn't already)

Clean the refrigerant condenser.
Ensure adequate ventilation.
Install an extractor.
Clean the cooler.

Or if you have already done/checked these, then it seems like you may have a problem with the switch itself. Try replacing the switch. I am guessing you have a manual for the Sigma Controller? If not then send me your email address and I can send one to you on PDF

Hope that helps

Model SM11 Running hot and shutting down.

by Fletch
(W. Henrietta, N.Y.)

Oil, oil filter, separator and filters are all new.

Compressor even runs warm when not loaded. Room temperature is in the low 70's.

Cooler completely clean and doesn't seem to be throwing off much heat. Maybe temperature sensor
is bad?

Bill says....

If it is actually running hot and shutting down, could be the air end bearings... or maybe a gazillion other things, Fletch.

Or, as you say, it could be the sensor if the compressor itself isn't actually running hot.

I can't tell from here?? :-)

Cheers,

Bill
