Hi I recommend you to check the exhaust sensor, the ERSA EWS500F is sensing the exhaust before it activates the fluxer. If the exhaust is not working then machine does not start to avoid the sprayed flux emit to the work environment. There is a sens

You can use one but over spec it. It will be a non-linear problem to figure out how much each exhaust port exhausts. Also have lots of shut off valves to shut off exhaust ports that you are not using. We have some holes in the walls in the back of th

Hi All, We are gathering information on the environmental conditions in our facility, including the fresh air exchanges. A driving factor is any point of exhaust that goes to the outside air and the CFM that it pulls from the facility and if there

If you calculate CFM using the numbers you have provided you are pulling 1396CFM out of the oven. I am not sure what Hellers spec is but I know a Speedline OmniExcel Air machine should be set at 300CFM. I do know for a fact that to much exhaust can s

I just purchased a used Heller 1500 reflow oven for an SMT line that I am ting up. Looking for the CFM requirements for my exhaust venting. Does anyone out there have any information on what the minimum requirements are for pumping this exhaust out

Did you just change anything on the Exhaust?... even if the change was adding something else to the main exhaust trunk, if you don't have each item seperated. Although CFM changes should not effect the Blower Speeds or the Zone stablizing time, since

Our Heller oven is functioning well. However, we see defects from the oven, such as shifted coil inductor components, and missing chip components from time to time. When we re-scan the board at the AOI, the defect was not present at that stage,hence

slowing-down the conveyor to allow the solder to heat these balls more. But that may not be the answer, because if the flux is exhausted, more heat will not help. Then if the flux is exhausted, the answer is to crank the belt. Two different answer

Hi, What will be the effect in my soldering if my Reflow Oven's Exhaust system is not properly extracting air from the chamber. Recommended is 100 CFM but I am measuring 45 CFM. thanks,
