100 CFM at each exhaust if you're using room air, 25 CFM/ea if you're using nitrogen (according to my manual...never used nitrogen myself) per their specified delivery rates.

Hi there , We just got a 2000 litre Nitrogen tank for our Heller1809MKIII Reflow Oven , it has been installed and calibrated last week but now the Oxigen PPM doesn't drop below 3000 . Did anybody dealt with this issue before ?

Nitro, I msuggest you get your oven manual out and start reading!! it depends on yoru machine, the point of injection, how many zzones it's designed to cover (some only inject for reflow) what your inward flow rate is, what yoru exhaust rate is and

I am currently running several SMT lines that are placing components onto dispensed adhesive (Heraeus PD 944). My problem is that we have always had an issue with a resin type liquid �condensing� on the inside of our oven chimney and then running bac

Hi SMTnetters, I have a white residue coating all over my reflow oven innards (almost looks like white fungus). How can I absolutely be certain that it’s flux and not anything else?are there any tests available for this? I am planning to check the ov

I'm inclined to believe along with others that if you don't smell it, and the flow rate is consistent (hence, your profiles aren't suffering from fluctuations in temperature due to fluctuations in circulation) you're probably OK. It does beg the que

yeah...I never had airflow volume problems with Hellers. When I had to build the system I was referring to, we had an old Speedline oven, and the way it was configured if you didn't provide enough airflow to the outer cavity, the blowers would overh
