List is 10,600

I can let it go for 9800 plus ship. Maybe ship included if you are super close. It’s a heavy box.

I also have independent analytical pump curve testing and graph ready for anyone who wants a performance verification of the new claims.

They also have a three year warranty. They are like supposed to be as durrable or twice as durrable as diaphragm. They claim nothing can stop it or damage it.

Damn, love the screw design. That’s baller for real.

.0025 is the glass co efficient for thermal conductivity. 1.01 is the silver co efficient for thermal conductivity.

When silver or aluminum is applied to glass it acts as a heatsink magnifier. It’s called thermionic electron emission. What do you think happens to a surface that was once less thermally conductive now applied with a highly thermally conductive material. You think heat just bounces off shiny shit and never gets hot itself?

Nasa doesn’t apply silver, gold or other temp/shielding to materials bc it’s not efficient or effective. They layer with carbon and blankets of specialty materials and backers and material in between to harvest heat waves back to the desired direction.

Also silver isn’t as used on heads lately. Most suppliers use a semi silver aluminum nitrate solution. For cost savings. And the thermal co efficient on aluminum is supposed to be 40? Percent higher than silver.

If anyone wants to talk about the spd8. I’m here to answer questions.

Hey thanks for the shwag bag @spdking HNY

Given equal dimensions (think layer thiccness), that would theoretically be relevant. On a column, there’s still a shitload of glass around around the metal layer (where the latter has absolutely insignificant thermal mass vs. surrounding glass), hence the exploited property is reflectiveness. You don’t make all that glass magically acquire thermal conductivity 3 orders of magnitude higher by applying a tiny amount of metal.

What’s the seperation quality compared to the hb with the halo?

Nah, they don’t because the layer thiccness required would make the shielding too heavy. Too thin and it’ll just burn off. That’s why ceramics :hot_face:

Are you an engineer or a pump specialist? Because if so, how does it feel to have all your funny claims debunked with simple physics F A C T S by some random n00b?

fact check me senpai

Now that you mentioned it i want a golden space shuttle!

  1. It’s not tiny. And 2. Yes it makes such a huge difference even with a small application. This is why it occurs.

Ok,
I’ll bite, what is the purpose of the coil inside the head?

So this is actually a design I had drawn up(original was way more complex and I was working on alot of projects so it got sidelined) and sent to rocco about 3-4 years ago. The reason for the useage with the components fitted inside is to allow the first coil to absorb as much heat as possible and remove kw energy from the vapor prior to entering the condenser arm. This solely allows the vacuum jacketed head to opperate like it’s supposed to. The coil in the head doesn’t disturb molecular in flow dynamics as it’s duty is to absorb heat before the heat affects the sides of the walls of the fraction collector as well as allows those ambient vacuum void temps to be more stable. See when you get blow by in a head it means it’s just working overtime bc the arm sends back fluids to the heater chiller and it can’t maintain the kw heat removal. So if you can maintain exact temps you can bounce unwanted fractions right out of the condenser arm without over shooting flow rates. This maintains a drier vacuum in the condenser arm. I supposed in a side by side if you dipped temps hard on a halo vs the spd8 they would be very similar. The halo controls the wall temps and that’s actually very usefull since you don’t need to waste energy maintaining the entire head temp with fluids you only target the location desired Wich where the halo sits. The targeted kw removal or maintenancing of the halo temp zone is extreme accurate and effective. The coil on the spd8 actually has a different type of fraction collector design so if you dip the coil temp down it will act as a violent collection of molecules dragged to the coil like a magnet. That coil would inherently distribute those lower temps right on the surface of the fraction collector and dish and that would display a whole new set of efficiency within the head.

This head is similar to a spd7 but it’s design was for traditional upright useage and it has a baffle non vig entry to the flask where the vapors begin to process in the upper area of the inside of the flask similar to hb.

I guess it serves multiple purposes. The head also has different functional geometry

Are you seriously the only person in the industry that knows this? I’m really trying to give you the benefit of the doubt, but my measly googling skills are not sufficient to find anything on thermionic electron emission in the context of distillation, let alone insulation in general.

No I’m not. I learned it from far smarter people than me.

Do you actually think I wasted time on patents and discovery of novel technologies as a example double vacuum jacketed boddies to increase head performance? Jesus. What a waste of time.

Still got these up for grabs if anyone needs a giant pump. Barely any hours. $8500 should probably do the trick :stuck_out_tongue:
