New Peerless Double Tie Mantles

Got the new Peerless DT-140 Double Tie mantles today.

The construction is similar to the Peerless 111 but with a draw-string on both ends, and should be suitable for a wide range of lamps including, but not limited to, Tilley, Vapalux, Bialaddin, Primus 1001 series, etc.

 

Looking forward yo seeing them lit up...

Cheers

Tony

 

Very good.
They almost look like old Primus original mantles.
These must be tested on a Primus 1001 or 1015.

I must say that it's a very strange business strategy from Peerless to specify "for Tilley lanterns" when they will suit so many other brands.

 

Would love to try them out and post an action shot or two, but that would mean sacrificing the good mantles that are currently on them. Oh, wait, I have a Vapalux M320 with a Veritas mantle that could use an upgrade...

 

Sam is an American, so perhaps he's not too familiar with other Continental brands and models. One way to rectify that would be to flood him with demand

They are also evaluating a shorter single tie mantle that should be just right for the Coleman 201 and 249. The current 2C-HG is too small and the 24A just too long. Will be equivalent to the Coleman #99 and should be a very versatile mid-sized single tie mantle.

The 24A, by the way, is actually intended for high-pressure LP gas lamps used by the Amish.

 

Who's Sam?

Exactly where did you buy them, by the way?
I can't find any eBay seller with these.
Was it from the distributor in South Africa?

If so, I guess my best option would be to contact the US distributor.

 

Christer, I'm the distributor for South Africa He sent me some DT-140 mantles as part of my last order, which I received today.

I don't see a UK distributor listed on their website, but there is a US distributor in Chesapeake, Virginia.

 

Ah.
I know that your name also is Botha, but I didn't reflect on that since I know it's a very common name down there.
Yes, it was that US-distributor I assumed was the best for me.
It's generally easier and quicker to get stuff from the US to Sweden compared to from Britain anyway, even if there would have been a distributor there.

Do you know anything about the DT-150 they also make?
Just a larger Double-tie, I guess?

By the way, the logic with the numbers seems to fail after DT-120. Those smaller DT's (Double-ties) are pretty much stating their CP rating (95, 110 & 120).
That is hardly the case with your DT-140 which ought to be around 300CP.

 

Yep, faster to get it from the US. He'll have to get them from the Philippines first, though. Not much demand in the US, I would think. Our postal service is in a bit of a shambles atm, but outgoing should not be delayed. I can send you a few if you are in a hurry.

 

The family name was Both from the city of Gotha in Germany. They left there in the early 1600s and moved to the Netherlands and a generation or two later, moved to South Africa in 1672. Somewhere in that time, the name was contracted to become Botha.

 

Sam Blank is the owner of Gasman Mantle Mfg Company in Manila in the Philippines. They are the manufacturers of Peerless brand mantles.
Very nice person to deal with.

 

This good news to hear for tilley owners. I checked the US site for them and I dont notice any e-commerce portal so I guess its phone them directly (gasp!) or wait for someone to put them online?

update: they should be available on a certain website come February

 

Hello Phil, some of the collectors on CCF., may be interested to hear about those mantles, Jeff.

 

It would have been more helpful if you'd just said which one it is...

 

Pish posh sir, its the one everybody is afraid to mention. The 'Bay. A seller by the name of "auctionthat".

Anyhoo, sorry for the vagueness.

 

Jeff, done and dusted, podner!!

 

Why would you think anyone's afraid to mention eBay? In that respect, it's no different from any other company on the planet. Mention away!

The membership has agreed that it's forbidden to link to live eBay (or any similar site) auctions, that's all - linking to BIN sales is allowed...

 

Hello Phil, that's good news!

 

Phil most kindly sent me ten of these DT-140, and I just tested one on an old Primus 1015.
I decided to take this one since it is such a good runner:



So even if it already had an extremely well working mantle, I just had to sacrifice it for the test.
But before removing it, I wanted to take a picture of it lit so I had something more impartial than the human eye and memory to rely on.
The camera was of course in manual mode in all aspects; shutter, aperture... you name it. And of course with a fixed white balance.
I also tried to keep the same pressure by pumping just as much in both cases and keeping the same initial fuel level (fuel/air ratio) in both cases.

But firstly the tying.
Phil recommended to sort of invert the mantle at the lower tying point, i.e. tie it with the inside out there, and then back it all up and tie the upper part.
I found this to be a good advice, because if you just tie the two points directly as positioned when the mantle is slid straight over the burner, much inner volume will be lost, so to speak...
You'll figure it out once actually doing it.

So here is a combined picture showing the different stages from the "inverted" tying at the lower end, the upper tying, the pre-burnt mantle and finally the pumped-up and cured mantle:




As seen in the last one, it is perhaps not as bulbous as we are used to.
This is what the old, generic double-ties looked like just before I removed it:




But the DT-140 don't look bad in any way.
It's evenly shaped and smooth.

Still... what we really are interested of is performance, right?

Old, generic mantle without the shade:


Peerless without the shade:


Seeing both live, I found the Peerless to be the better.
And hopefully these pictures - with all camera settings fixed at the same - will confirm that.
It is a stiff bastard as usual with Peerless. The fabric they use is still like plastic.
That is seldom a problem with a single tied sock mantle, but at a double tie like here, it is a tad bit awkward since you normally want to stretch it out from the burner and shape it as well as possible before pre-burning.
It looked a bit too askew directly after the pre-burning, but a good initial pressure pumped it up fair enough anyway.

 

Proves that size is not everything . Nice to have another choice to try.

 

That looks positive to me. Now I have to get some for my 1001/1014/1015 lamps.

 

Yes, I think it's worth a shot.
Perhaps you get another impression than me, but I think it worked well even if perhaps a bit fiddlier to tie than a softer version.
Mind you, I have only tested this one yet.
I think I shall try another lamp and tie the mantle the "normal" way, just to see how it will act and be shaped.

 

An impressive increase in the light!

 

A good demo and I'm glad they are working well!

 

Well, it worked pretty much the same, even if the one tied in the other way looked better.

I tried the second mantle on a lantern; .

Firstly I took a picture with the old and perfecty well working mantle, again with all settings fixed on the camera, and with the same amount of pump strokes etc.
As I said above, I would try this one tied the more normal way, and actually I think it worked fine.

Tied, preburned, preheted and after an hour of action:



Again, the Peerless looked more shapeless, straighter and less bulbous than the normal two-tie, but the light output is absolutely better.


The two pictures below is of course taken with the same camera settings in all ways and the lantern with the same fuel volume and pump strokes, etc.
The Peerless is shown in the second picture:





Strangely enough with these Peerless, they give a tad bit warmer light. Normally Peerless give a colder (read whiter) light close to 3500-4700K, but these look more like around 3000 to me.
Which suits me even better. I'm not a fan of cold light.
It's just in peoples head that a colder light is the same as a better light output.

 

I am told that the perception of light intensity/colour is in part due to age. As we get older our cornea begins to yellow, causing our brain to prefer a colder colour, as it is perceived as brighter, allowing a clearer image

 

I don't think much ageing went on between those two shots!

Impressive.

 

Time is relative
The difference is very obvious, and in my perception a large improvement.

 

The difference in colour temperature is probably because these DT-140s use yttrium and not thorium. Most thorium today comes from China and they have recently placed restrictions on export. The little thorium available to Peerless is mostly reserved for the mantles shipped to the Amish.

There is some speculation that the Chinese are stockpiling their thorium for use in Molten Salt nuclear reactors which is a vastly superior, cleaner and safer type of reactor that produces almost no waste and can in fact burn up the waste of older type reactors. It is an inherently safe design which can not melt down and also cannot produce weapons grade plutonium but can produce medical isotopes cheaply.

 

why the Amish?
