    Default Re: Band heater vaporizer.

    I have a couple of questions.

    1) How are you measuring the resistance of the band heater?

    2) My hives have 3" walls, top bottom and sides because they are insulated for the NE Minnesota winters. Any way to use these DIY units with a long exit tube?

    Thanks

    Chad

    Thanks for the list. I am buying other parts from MSC DIRECT as I have a pro account with them. Will list them once received. Your PIP does not include a solid state relay. Do I need one?

    Alex what is the wattage of your band heater, one needs to be a little careful that the wattage is not too high as the contact ratings of the TA4-RNR is only 5 amps and quite frankly I would not exceed 50% of that.

    I dont see a need for solid state relay unless you dont like the clicking sound a of a mechnical relay.

    Thank you. I read on another board that RNR do not last as long as SSR. I went the SSR route.

    I tested out my no braze design yesterday. It worked well, I was a little worried the plug would not seal the threads. Turned out not to be a problem. It was a bit slow. I think my set point temperature is too low at 365F. What are most people running on their vaporizers?

    I run my vaporizers at around 450 F this allows a certain amount of stored heat so that when the OA hits the bottom of the bowl there is sufficient heat reserve to boil off the water of crystallization and sublimate the OA in quick time as the 275 watts that I use could not provide enough of the heat required to provide the amount that the latent heat would require to change the state of the water to steam and and the OA to vapor in the time I would want. You will see the temperature overshoot the 450 F mark but not to worry cause as soon as the OA hits the bottom the temperature in my units drops to around 320 F and when it has climbed up to around 400 you are done and time to move on and on my units that is between 20 to 30 seconds depending on the OA load. My unit also reaches 450 F in around 100 to 120 seconds depending upon ambient temperature.

    johno, Thanks,450 degrees worked great, also helped keep the nozzle clear. My unit takes about 20seconds to vaporize 2 grams. The unit never drops below 420 degrees due to its large thermal mass. It does take about 5 minutes to get up to operating temperature.

    Alex, do you have any issues with the aluminum smoking? According to MSC, it smokes when you hit 400F.
    Also, I have learned that 1/8" nipple is not 1/8" ID. it is actually 1/4" ID and is the smallest ID they have at MSC. Ideally a 1/16" nipple would be the ticket to approach 3/16" ID. I will go with 1/4" ID as I have no other alternatives.

    1) Pipe sizes/threads in practices often like dimensional lumber. Actual dimension is different from the named size.
    one from Amazon that is in stock ASIN B074W4B62Q
    https://www.amazon.com/dp/B074W4B62Q/ref=dp_cerb_1

    2) Please send me the link. Never heard of AL smoking, but all the contaminants sure do. What is your question? Aluminum 6061 retains 50% of its tensal strength at 480 F. there is more to worry about when compared to the Acid Vapor you are creating.

    Hello Alex, there is no link, just a comment that their specialist did when we were chatting. Do you have a picture of your finished contraption? That would be helpful before I start drilling holes. Further, what is the ID of the apex of the nipple? How hot does it get when the whole rig is warm enough? Thank you!

    What are you using for heat wrap, and how are you applying it? Thanks all

    I use 5/16" grapho glass, start at the top and clamp the stuff under the band heater clamping screw and then wind it all the way down to the bottom and tie it off on the bowl mounting screw. I would prefer straight fiber glass rope but could not find any.

    I was thinking of using the fiberglass exhaust wrap like this..https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

    Any insight would be welcome.

    The problem with flat fiber glass tape is that it will not move to the contours of the bowl especially where you go over the band heater clamp so you end up with something untidy.

    I believe I heard 12 volts in the video. A google search showed 480. Pricey and back to having a battery. Ill be interested to see what other people have to say.
