    I bought an mk3 terpp extractor from Terpp Extractors and having problems with my recovery pump bringing my system back to -10 inHg from 1st recovery...it's been an hour...it usually takes about 30-40 minutes to recover 4.350 lbs of butane I soak my column in, but I've been having pressure issues with my recovery tank today. When I first introduced butane into my system, it shot out really fast, like 2 pounds in 5 seconds. I'm not sure what is wrong, because I triple checked hose fittings, vacuumed my whole system and let it sit for an hour to test if it would hold. The only thing I can think of, is maybe my chiller coil is frozen? I have it under dry ice and isopropyl alcohol that has now turned into a block of ice that won't let me remove the coil. I read somewhere that maybe I introduced oxygen into my recovery tank, and that I need to 'burp' that out? Any help is appreciated, thank you

      Non condensible gasses, aka entrapped atmosphere, is one cause of sudden long recoveries. I would chill the supply/recovery tank and burp it of any entrapped atmosphere by burping it out through the vapor valve. If you have the chiller coil after the pump in alcohol and dry ice, the chance is good that it could be frozen. What size is the tubing and how long a coil? GW

    A friend of mine did a BHO extraction. He notice that under a blacklight that the oil was outgassing at room temp. Does any one there know what is coming off ? Thanks Ron

    I have a small stockpile of empty R-600 Butane cylinders ... how can I recycle these, none of the local busineses want to touch them??

    Ecogreen's refrigerant smells like Freon. I feel any professional would stay away from refrigerant. Also you need a new gasket supplier. My friends and I, use single pin 2 in clamps from Emerald Science all day every day no problems. We've been beta testing their in-line dewaxers mine has 3 2in ptfe screened gaskets. Again no trouble at all I traded the high pressure clamps for more single pins.

    You say to tighten the nuts on the high pressure clamps to 44lbs. I bought a new Chinese torque wrench and set it for 44lbs. I tried it on a bolt that I clamped in my vise and it did click and seemed to work fine. When I tried tightening the actual clamp nuts to 44lbs the bolt actually started to bend and the clamp was nearly completely closed and the torque wrench never clicked. I was told by Glacier that the clamps are not supposed to be fully closed with both halves touching. I always tighten both nuts equally until the gasket starts to squish out just a bit. Are you sure the 44lbs is correct? Where can I get PTFE tri-clamp gaskets. Do you ever purge the loaded column with nitrogen prior to the extraction to dry out the column, similar to a refrigeration style triple evacuation? Does pulling the column into a deep vacuum prior to extraction destroy terpenes or cannabinoids? Either way it has to be done but perhaps a person should limit the time the loaded system is kept in a deep vacuum? I keep my 100lb butane storage tank in a chest freezer full of anti-freeze with a continuous circ pump and hydroponics type chiller. Needless to say my recovery time using twin TR-21's is lightning fast. I guess any water in my storage tank would be completely frozen as the holding temp is zero degrees and max operating temps have been barely above freezing. Do I need to worry about water in my tank? I also freeze my loaded columns prior to be placed on the extractor, any concerns about doing that?

    Very interesting! I do not have nitrogen on my system, and am curious how it would help. Would it help stop my shatters(snapable) from crumbling? I am located on a mountain so my gauges never read -29 Hg. I found that the tr-21s brake quickly when I brought the system down to -20 hg. Ive done over 700 hrs with the current pump and usually stop before -15hg

      Someone correct me if I am wrong, but I believe the nitrogen is to create an atmosphere devoid of oxygen in the unit. This would make it impossible for any residual solvent left in the unit/collection to catch fire when opening the unit after an extraction.

        Diluting the 25% butane atmosphere present at -22" Hg, with nitrogen, both further dilutes it and shields it from the 21% oxygen content in the atmosphere, when the pump discharges it. Ostensibly, a vessel that has subsequently been evacuated to -29.92" Hg, and again backfilled with nitrogen so that it can be opened, has little residual butane left to ignite when the vessel is opened.

      It is certainly true that oil less pumps don't last as long under vacuum, because they are running with little lubricant on the piston seals and have little gas flow to carry away the heat generated. The crumble is usually a hydrate, which needs water, and dry nitrogen helps lower water content by drawing away the molecules with them as they exit.
