I was checking out GB-234 to use with my EQV. What size fittings are those on the 234? Are there any other water filters I should consider? I like that the 234 has gg fittings on the inlet and outlet.

If you look at my time-series temperature data (figure 1), there is not much benefit to pre-heating (percolating) fore more than a few minutes. IMO, anything over 3 min is overkill, especially if you leave the empty elbow / whip on the unit while it's warming up...I don't see any major drawback...

Actually, just buying a higher power output power supply (PS) isn't going to necessarily help. The heater has a specific resistance which means it draws a fixed amount of current at its designed operating voltage. If the power supply can already meet that requirement, then buying a higher...

If I was going to do a bag with just enough herb to fill 1-2 bags, I would pre-heat to 180C (160 if you are using the cyclone bowl) and then increase it to 230C (220 if using the cyclone) after about 0.5-1 min of filling the bag. That will release all the volatiles (THC) without cooking them in...

Good morning FC, In case anyone was curious, I went ahead and took some pictures last night of the guts of the EQV. It was pretty straight forward to disassemble. I probably should have used a better camera but these pics should give you an idea of what it looks like inside. Here is the bottom...

I would only use the fan at F1 if you want the most consistent air temperature. it's not that the heater can't keep up; You can increase the air temperature while the fan is on by increase the temperature setpoint. The problem is that the thermocouple is located inside the ceramic cartridge...

The data has been updated to take into account my fuck up with the thermocouple calibration. The results are much better now in terms of how well the controller is calibrated. The same transient issues are still present but we can be confident that the unit is accurately giving us air at the...

FC, I feel like an idiot :( . I decided to double check my measurements today using a different thermocouple; I was suspicious that the temperatures were incorrect (too high). In the process, I determined that the setting on the thermocouple reader was incorrect for all the transient...

Yeah, I think that you're/we're not going to see much difference. If you want to avoid the sedative effects/chemicals, based on that info, I would go lower in temps. Remember that even if you're above the flash-point of your compound of interest, you still need an ignition source and the proper...

If T,setpoint actually is indicating heat duty then the manufacturer is lying to us in the manual. If this is true, at least it doesn't ramp up the heat duty (heater voltage) immediately to the setpoint during warmup. That will prolong the life of the heating element. I haven't been paying...

The low flash point of some of those compounds (CBD for example) makes me think that the temperature program should start much lower (T,setpoint = 130-140C) so you maximize vaporization of THC and CBD and minimize combustion. However, I don't know how the flashpoint was determined (did they...

Yep. Best thing to do is just do the experiment and observe how toasted the herb is getting with the setpoints you used and optimize from there. Hopefully this data will allow people more quickly find their optimum... The percolation/pre-heat temperature in the cyclone or elbow doesn't really...

[Edit: Note that these charts have been changed to reflect a systematic error on my part; I was using the wrong thermocouple calibration JvsK] Good morning FC, I have more data for you... Here I was concerned with how the fan speed affects air temperature. The conditions were T,setpoint =...

Elbow versus cyclone data. Elbow is about 10-20C cooler over the temperature range 175-230C.

no, you are correct. The manual specifically states that the readout indicates "heater core temperature". The data are counter-intuitive [Edit: not anymore!].

That's right. The actual cyclone bowl temperature was much higher than what it said on the EQV readout. The the offset is very linear over an 80C range which makes it easy to convert.

Hi again FC, [Edit note: The original data in this point has been replaced with corrected data. I was using the wrong thermocouple calibration setting Jvs K] I completed some more testing with the EQV. This data set is more applicable to all of us because these transient experiments replicate...

Thanks all. I'll do some more testing tonight after work :brow: One thing you have to keep in mind with the fan data I presented so far is the fact that they are steady-state values as I was mainly interested to see how well the unit maintained temperature with varying fan speeds. The initial...

The temp controller is either Proportional control only or the temperature set point is just being converted to a heater duty cycle (i.e. constant heat output / watts)...or a poorly tuned PI controller). I'm only trying to understand its nature so I can use it more effectively....

Hi FC, [Edit: For more accurate numbers at relevant conditions; please see my other posts further down in this thread] Just got my first Vap, an EQV. Works great. Being a Madscientist :brow: , I've done a little characterization work with my thermocouple (bare) + reader. Below are some data...
