Our problem is with the chamber beneath the drying section, where the blower is. The drying section vents directly into the chamber beneath it where the blower intake is, which is great for equalizing pressure but really counter to presenting dry air

Depending on Zone Temperatures, Belt Speed, and Board Density... Some Convection Ovens will drop Zone Temperatures faster than others. They recover by increasing Air Circulation. This can make parts fall off the Bottom-Side that otherwise would

Is your oven adjusted correctly for temperature > and blower and conveyor speed? As far as blower settings it only has a Hi-Mid-Low setting (is a heller 1809), and we have been working with all at Hi speed since line was started (1.5 year ago). Co

Just a comment on the Heller 1500. We had 3 at a previous workplace where we never made the Pb-free transition (this was early 2000's). The ovens we had were not designed for and were never used for Pb-free processing yet every one of them had all o

Good day. We have just purchased a HOLLIS POLYCLEAN SMT Machine. We did not receive a manual and for installing the machine, we need the indications for the ventillation system: ie the number of CFM for the blower. We would greatly appreciate it if

Oh, I see, concerning the fee. Sorry. Running NitroCool without N2 is possible, but cooling performance will be weak. You will want to get the higest flow out of the blowers. Try taking it all apart to remove bits that abstruct flow. Good luck.
