We want a D5 Vario mod top...NOW!! Listen up fokes

[Jimmer411]

Any updates on this at all?

[DetroitAC]

A small update from me (although I think you're asking EK!)

I've switched my development efforts to using the stock Laing screw thread attachment since the price will be so much lower if most of the Laing hardware can be reused. I've been thread milling the buttress thread at the connection, and thread milling the G 1/4 threads. I just finished milling my 10th iteration (v10) last night, so I am making development progress, but the performance is still not there.

is the performance atleast on par with the stock top?

I know that whichever tops hits the market first, I will take 2! this will look sexy one my 2 D5's!

It is just slightly better than stock in all the versions so far. I haven't tested the version pictured yet. Keep in mind these are development parts, I'm only working on the internals, not cosmetically finished externally, in fact the edge that I don't need to locate from are left with a table saw cut (one such edge is in the picture).

Looking good so far. Just a quick question, do you miss R-12?

[kolombo]

Have anybody played or thought about impeler diameter and rpm . Without increasing the velocity genereted from the impeler , looks to me mission unpossible . At first place and the easyest way to me , some new impeler diameter and slight volute work .

Any more progress made on the EK top?



Im lookin forward to these hitting the retail market

[philbrown23]

the koolance top will not find it's way into my loop any time soon. But thanks for the suggestion

Nice nice, Ima have to follow that one.





I guess EK's is no longer in development? Havent heard anything in forever on them

[Aqua-Pc's]

I think you will find they are closer then you think

[MomijiTMO]

Oh wow. That is a great sign.

[Jimmer411]

I think you will find they are closer then you think

Well I hope so. Its high on my list of things I need before I do my next build.

Hi all,
I have noticed allot of bashing on the Koolance D5 top, I just wanted to chime in with my $0.02.
First off YES the top is made from an aluminum block; however the misconception that it is a bare aluminum top is false. This thing is nickel plated to combat corrosion. So the only thing that the coolant will be in contact with is the nickel plating. Second koolance recommends the use of their coolant with all their products mainly because it is loaded with anti bio & anti corrosive ingredients. I have the COV-PMP02P d5 top from koolance and I haven’t had any issues with galvanic corrosion and it most defiantly improved the pumps performance. I am still using the same coolant today that I installed with 3 months ago and it is as clear as the day I dumped it into my system. But on another note if you where to use just water or another coolant with poor anti corrosive properties you will most likely have corrosion at some point no matter what metals you use. This is true with any metal you use for cooling blocks. So for my final thoughts I would like to point out that if you are planning on using a koolance system this would be a great top to buy. However if your mixing metals in your loop your inciting corrosion to take place but I doubt that it will start with this top. The nickel plating would have a slower corrosion rate as opposed to bare copper or bare aluminum. I have personally installed this top on d5 pumps in systems with copper Rads for my customers and they have had no issues with the top being a source of corrosion. But I should point out that all my customers use coolant with strong anticorrosive properties at my recommendation. Also because koolance nickel plates all their new stuff galvanic corrosion is no longer a big issue in a koolance system.

on an other note,
Good job on the blocks your making mates. I am very interested to see how well they improves the pump performance.

Well said, but you have to agree that three months isn't much of a test run for corrosion. No matter how much anti-corrosion you put in your loop you will still se degradation over time if you include aluminium in your loop. And I would advise you not the compare including aluminium in your loop with the mising of copper and steel. It is a whole different game...

Nice to hear that your customers are satisfied, BTW!

[Jimmer411]

Ill trust the quality of any coating on alu the day I trust a a woman to dispose of the condom after wards. Your giving life an opportunity to throw you a curveball when you take certain risks, and honestly I dont want any nastly little surprises 6 months from now Do you?

[septim]

i hear current batches of koolance fittings are nickle plated brass, no longer nickle plated aluminum because of some issues a while back...

[biggles1]

Anyone else noticed Martinm210's sig lately?

I sure have! Martin, tell us about your new top!!!!!

[John Planet]

Forbidden Koolance llol

I think the Koolance one is perfect except for it being alu. Dang it's so sexy

That's just what I was thinking, but I was chicken to say so. It is very sexy. I've got 2 D5V's collecting dust that I'd find a place for if I could get some sweet parts for them.

[Sugar4o]

I sure have! Martin, tell us about your new top!!!!!

Where did you saw a top? I couldn’t

My version of a D5 top will be ready by the end of the week so it will be a testing weekend for me. I’ll keep you all informed

[Sugar4o]

Mmmm I like competition! I doubt to see the results before mine so it will be a blind contest

Three months is not long enough for a system with all copper, but a mixed copper and aluminum system will achieve galvanic corrosion much faster in my experience. for example, when I first started my move to koolance products it was done by testing much of their stuff with allot of my custom milled copper blocks I made in my shop. The results of running water, a bare aluminum rad, and copper block where horrifying. I couldn't believe koolance was peddling this crap to people. However as I started to research their products more I realized that they don't intend their stuff for use with other manufactures stuff. All koolance product used in a koolance system will perform better because they were all designed to work together. I still think koolance just needs to make their stuff from copper and brass so their stuff can be mixed and matched without the hassle of corrosion. So when I tested an all koolance TEST system the performance was better and corrosion didn't start to Appear till about 19 months. However this was due to the old aluminum fittings and copper blocks nickel plating stripping off at the threads exposing copper and aluminum at the same point and corroding... BOOOO!
So, back to my point, at three months running a mixed mettle system I should see galvanic corrosion and I am not. It is proof of the fact that nickel plating is great at preventing corrosion. This is why allot of industrial companies use nickel plating on their machines, to provide a long term protection from corrosion. I will however post it in the forums when it finally does corrode, and why it corroded. Given the fact that I am using the new nickel plated brass fittings from koolance I won’t be having any problems with them causing the corrosion. Right now I am watching the Koolance Aluminum rad and D5 top right now to see how durable the nickel plating is. I never said anything about steel beings used in my loop. The only thing I said is that galvanic corrosion will happen in a system despite the metals being used given time. The whole point of my post was to argue that nickel plating all your metal components like koolance does, will help to prevent galvanic corrosion especially when combined with a cooling fluid with strong anti corrosive properties. I will say this; Koolance should have made that D5 top from Copper and not aluminum. So I will grab an extra koolance D5 top off the shelves and go about reproducing it with a copper block and then nickel plating it. I will have to make a custom mounting bracket as well to handle the extra weight of the copper. For Shidzfa and giggles I will make the mounting bracket multi angle adjustable for mounting in different systems. Might be able to sell it in my shop. Should take about a month to produce, I'll keep you guys posted.

First off I would never trust a woman with anything... Second the quality of the nickel coating is actually very good. Koolance uses a Phosphorous Electro less Nickel plating which offers excellent resistance to alkaline corrosive environments. This is an industrial standard and I have allot of machines in my shop with just such nickel plating. The point being that with this nickel plating prevents corrosion for the duration of the coating. Given that the only thing coming in contact with the nickel is liquid coolant it will last a very long time. However that’s not talking into account that something ells might strip the coating off like the constant removal and reinstall of threaded fitting. This is actually how my first koolance test system corroded. The aluminum fitting and copper block lost the nickel plating from constant friction. But at 19 months before that not a single bit of corrosion occurred and probably would have stayed that way had I not fiddled with the fitting so much. I am now using Koolance’s brass fitting so this won’t be an issue anymore. Taking risks is how we learn about new ways to do thing so YES I would take that risk, but I can also afford to do so. I have more trust in nickel plated copper and brass systems than I do in nickel plated aluminum and copper systems but if you take good care of a nickel plated koolance part it will work as intended.
