Keenovo Heat mats from china

[Chonkski]

Exact temperature shouldn't be an issue, so I'm going to the mechanical control for now.

I will ask about the thermocouple when I send the email. Which will be after I'm done with processing for today.

I'm getting them for the 4"x36" column. Do you suggest I get one large one still?

That's fine that there is an inch of room left, although, would it be too wide to use on a 3" column? I like the 3"x36" columns for my smaller more "top shelfy" runs

the circumferance of a 3" circle is ~9.5" so the 10x12 inch long ones will be to wide..... I think lol. With the tube thickness it should be right at 10" circumferance, so you could turn them sideways for your 3" column and they would work. But they would be kinda small on your 36", and you cant make them wider then 10" if you want to use them on your 3" columns too. The picture i posted a page or two back is my column(4x24) with 2 10x12 mats

Can you help me i don't like the heat gun defrost ether . is Exact temperature an issue on the column ? Im looking at 400 Watt 120 110 Volt V Silicone heating mat a 9'' x 15'' (without) a controler just a plug for a 3''x18'' column it will fit 1'' short on each in with a 1/2 gap on the rap. It said They have internal thermostats to keep them at 160 degrees F is this to hot? hope you can help thanks

Sanitary spool diameters are given in OD, so the tube diameter times Pi, or 3.14159......... will give you the circumference.

Some of the mats only roll in one direction easily, and has been noted, you can't overlap them without burnouts.

The sanitary tube lengths are also net, so you have to leave room on both ends for clamps. If you bend the mats around the clamps, they will fail at the bend.

We are having our type J thermocouples molded into our heat mats and control them with a Mypin PID controller.

For 4" columns, we order them 12" wide for the circumference, and 10" tall. A 24" column gets two of them and a 36" column gets three. Only one mat thermocouple is connected to the PID.

PS: Don't lose track of your total watts. WolfWurx wires their machines 240V, and splits the two legs into two 120 V circuits. One for the mats and one for the vacuum pump.

Finally got my shipment from Keenovo. It was supposed to be here 2 weeks ago

That is a 10" x 36" 720w for the column and a 4"x34" connected to a 12" diameter mat for 510w of power. Both hooked up to STC-1000 PID controllers with NTC sensors instead of thermocouples. Just need to clean up and pot the wires and it should be ready to test out tomorrow!

How flexible is your mat in the short direction?

 

[montroller]

^^ super flexible, I can roll it into a 1" diameter circle no problem

I am curious to see how NTC sensor performs compared to thermocouple. When I was trying to research sensors I was finding that the main benefit of TC sensors is they can be used up to 2500 C. NTC sensors are super cheap and are designed for applications under 100 C. Also they are supposed to have better accuracy even after years of use.

When I was just testing the heaters and PID controllers the sensor seemed slow, or maybe it was the controller, but it was WAY overshooting it's mark. Hopefully the freezing spools will help to counter that.

Also I am trying to think of a nice convenient way to attach the sensor to the spools. Ideally it would be easy to remove and attach so I could move it around to different points at different stages.

You did order during their chinese new year time so they are usually behind from end of december to end of february.

Im going to have them put those nice velcro straps on mine next order.

Looks good!

"STC-1000 PID controllers..."

1) Not PID controller

2) It employs mechanical relays, I have no idea if they are internally sealed.

Can they do one long vertical velcro piece?

I have a nephew named Montrasier, amusing.

 

[montroller]

Ha, I didn't even realize they weren't PID controllers. Well they seem to be working pretty well. Also I'm not too worried about the internals because the conduit box I got is sealed with a gasket.

I was able to recover .25 - .5 lbs more solvent from the column each run. The first run took about twice as long to recover because I was being conservative with the heaters. The second run took the same time I have been hitting with water baths, which is still kind of slow. I am hitting 12 lbs in 1 hour and I think I can cut that in half with the proper equipment.

Still experimenting with the sensor in different spots and I might just grab a mypin or two to compare accuracy. It would be nice to control everything from one controller.


Also who names their kid montrasier

Our early ones, we just clamped our thermocouple between the matt and the column with a radiator clamp. We now have the thermocouples molded into the mat.

can anyone help me pick the correct size for a 6 inch by 36 inch column ??

Hey MMB, I was curious to know how that 12.5"x34" heat mat is working out for you?

I sent them an email for the same one for my 4x36 column as well. But they have been absent for a while now.

Just wondering if it's too big in any way?

I actually changed my order slightly and had mine made 12x34 instead. You definitely would not want to be any bigger on a 4 x36 column. Works great, but i really have not put mine to good use as of yet because I ended up sending half of the substandard extractor equipment I ordered back to the MFG(CRAP), so now i am waiting on China to awaken so as to proceed with procuring the rest of my much needed equipment and supplies.

China's still on Spring Festival and CNY holidays, I imagine they will get back to you next week.

 

[gholladay]

Great photos Montroller!!! That's a great setup.

Chonski and Mary Brown, what controllers did yall go with?

I just went with their standard digital thermostat using a NTC thermistor of 100K as temperature sensor. I did not think I needed the more expensive PID controller for this particular use. I did however order a couple other ones with a PID control for use in a more temp sensitive setting.

Nice, thanks for the help. that's exactly what I was going to order for the 4x36. The 12"x34".

Yeah, it mentions that the seller is supposed to be back on the 24th(yesterday) so it should be anytime now...

Gholladay:
I am going to go with the cheaper mechanical controller as well for the column. I have no need for it to be precise, just effective.

Chonski,

That's a really good point. For column heat and recovery you really just need it to turn on and heat, not modulate around an exact set point. And I imagine those controllers do a decent job of modulating the heater any way. Thanks!

 

[A6 Grower]

The mechanical controllers work great! Well... I have no idea how accurate they are but they work! I just use them for the columns and could care less what the temp is just as long as its warm i'm happy. The best part is now with the heat mats my columns are easy as cake to clean out, i just push all ~900g out of my 4x24 with almost no effort, just slides out. The outside layer of weed is kinda burnt looking sometimes. The only thing i dont like about the mechanical controller is the cheap temp sensor wire thats solid metal and kinda a pain to deal with, always gets caught on shit, other then that they work great for the price. I think i may make my cords longer so i can move the machine around a little more without fear of pulling the wire out of the controller.
