which resin is best or longest lasting

[DASERVICES]

You will not find much difference with Tulsion and Dowex, but have never tested Dowex but have seen the specs.

Purolite is a lower spec so not as rigid as the above, have had many customers confirm this. Purlolite do have a resin in the same league but is not sold for window cleaning.

Sybron cannot comment but spec is nearly the same as Tulsion and Dowex.

Tulsion MB-115 is a nuclear grade resin, Purolite MB400 is not so hence higher spec.

Rohm is same spec as Purolite.

Biggest factor is resin is di vessel and flow rate.

My answer is keep trying until you find what suits your quality of water, don't stay with the same product. Keep trying as you could save double your costs.

[aztec]

i find mb400 the best

[windowwashers]

I use Dowex.

I have heard good reviews of Tulsion also and some very bad ones about puralite

most popular maybe not the best, or maybe this is just down to what people like. I have never heard a bad comment about dowex or the other, just bad ones about purolite.
Does not make me right it is just what I hear, hence why I use Dowex.

Likewise 

[DASERVICES]

There is a website Reskem.com which I get all my details from, technical stuff but once you understand you then know what resins will perform best.

[alanwilson]

dowex is made for champions and good people.  thats why I use it

na really I have found it to be the best so far, I have tried Rohm&Haas, puroshy..lite, dowex and bayer.

not one of them comes close to the dowex, it stays at 000ppm for much longer, and when it does start to rise it doesn't rise as fast as the other resins.

these are only my findings and are not scientifically accurate nor do they constitute part of a program of research.

[steve.ternent]

I have only ever used

Sybron ionac NB-60 a mixed bed of strong Acid 8% DVB
Type 1 Anion Gel Resin

How does this rank ? 

I must admit I don't know anything about the different types

Probably because suppliers like you only sell it because of the quick turnround of business it creates for you, repeat custom.

It's sold to unsuspecting mugs unfortunatley who don't know any better & rely on ( poor ) information from you & the likes who also sell it.

It's pants, many of us on here have proven it, it's a BIG, BIG, RIPP-OFF!

tony which resin is a rip off sorry its not clear and which DO YOU think is the best

[edd]

ay tony just read the other post Dowex then .......where from and how much cheers mate

[DASERVICES]

Purolite             Dow                    Sybron            Thermax              Rohm & Haas                    ResinTech
NRW-37         MarathonMR3          NM60                MB-115                  IRN-150                         MBD-10

These are the equivelant resins which some are on the market for window cleaning, all the above are nuclear grade resins which are higher spec and therefore higher performance.

Purolite MB400 is a non nuclear grade resin, Purolite NRW-37 is a nuclear grade resin and higher spec than MB400. If NRW37 was sold on the market then yes it would be equivelant to the above, but would be the most expensive product on the market.

I am not indicating that everyone goes and stops buying Purlolite as the window cleaning market does need all these makes in the market due to world wide shortage of resin.

But all the product data speaks for itself, MB400 cannot be classed as equivelant to Dowex and Thermax as it is a lower spec.


Doug
All this data can be viewed on the Purolite website and Roskem website.

[Moderator David@stives]

Why would you want nuclear grade, all you need is to get the tds down to an acceptable level to clean windows , ie 0 tds not lower.

just because it is nuclear grade does not mean it will last longer !!!

[Rogue Trader]

which is the best supplier of dowex ..... im all run out and need to get some quick!

Dave,

Trust me it does, each product will have a spec which you can obtain from the manufacturer. From 100ppm you get xxxxx liters.

I will take Dowex spec, at 100ppm you will get 7000l. But you have to bear in mind that is in perfect conditions so with window cleaning you would get slightly less.


I have loads of customer ex Purolite brigade that now get through a bag every 3 months instead of the usual 1 month.

Tony, no offense, but you speak from a very limited view point and experience too make such brash and obnoxious statments. I can't see how your 'opinion' is the be all and end all? Far from it.

The proof is in the pudding foxman.
I SUGGEST THAT ANYONE CURRENTLY USING PUROLITE CHANGE TO DOWEX OR TULSION, THEN COME BACK & TELL US ALL WHO IS RIGHT & WHO IS WRONG! ( apart from dave morris who you have too much influence ).
I understand your concern, as if you supplied the correct resin you would take a serious drop in profit. However, i'm here with no financial interest, only to save fellow wfp'ers lots of money in resin.

So, if anyone would like to take up the challenge, i am more than willing to be shot down in a hail of 4 letter words for talking rubbish! I know it won't happen, what i say is true & not vested in financial gain.

Anyone?

I cannot comment on TULSION as I have never used it, but if a supplier wishes to send me a bag I will give give great reviews if it is as good as dowex and maybe even change to it.

macmac

no one has influence over me, if you ever met me you would know that.

I speak my own mind and i am nobodys puppet or fool.

AllI have ever said is give us proof not hearsay, whats wrong with that ?

[alanwilson]

the proof is this -

anyone I know who has used Purolite in the past but has also used other resins will not use purolite again.

our own findings indicate that dowex outperforms purolite completely, lasting roughly 3 times as long - I don't expect anyone to take this as scientific fact but we don't buy purolite anymore.

when nearly all the major suppliers supply purolite you have to look at why - simple, it just won't last that long so they gotta keep coming back.

There is no hearsay dave, why on earth would I with absolutely no financial interest in who buys what resin come on here & say anything other than what I know to be totally correct as I have used, tested & compared it. There is no comparison to DOWEX! Only you can proof it to yourself but IMO unless you put your DI's in the van then you ain't gonna see any benefit.

Alan Wilson is absolutely correct in his post.

Tony

[Moderator David@stives]

Now that is 2 arguements.

Only lasts more if it is in the van ?

[Moderator David@stives]

I trust Alex Gardiner, he is soon setting up a water station for local window cleaners so i think he is best placed to do some experiments.

I will have a word when he gets back.

I dont doubt you believe your views are right but to preach to others you need proof !!!

[alanwilson]

DOWEX CHA CHA CHA
DOWEX CHA CHA CHA
DOWEX CHA CHA CHA

Now thats not shouting, its singing.

[macmac]

Yeah, we've had this one before- flow Vs volume. remember?

You blast water at mains pressure through any DI ESPECIALLY using purolite & it aint gonna last 2 minutes. purolite DO however make a resin that is designed to be used at a higher flow rate, but it aint MB400 that you buy.

Tony

[ronnie paton]

so the flow rate effects the life of resin??
i have a di system the water is flowed throughthe resin from my 60 psi pump, can a do anything to change the lastability of my resin?

[macmac]

Thats fine but some fill their tanks through di from tap, which is fine if the flow is gentle but not so good if not.

Tony

[ronnie paton]

ah so the higher the flow the quicker the resin is exhausted?

[alanwilson]

ah so the higher the flow the quicker the resin is exhausted?

yes

[Moderator David@stives]

Maybe

ah so the higher the flow the quicker the resin is exhausted?

Maybe but not enough to worry about , in my opinion

[DASERVICES]

The resin is not exhausted, what is happening you still have good resin in your di vessel. Water runs through loads of channels in your di vessel hence when you give it a shake the tds drops as new channels have been created.

When you slow your water flow down then the resin has a better chance of absorbing the TDS. For example my TDS crept upto 002 and I slowed the flow rate down and it went back down to 000.

2500l on and it is still 000. In the past I would have chucked it out but now with the information I have I get more out of my resin.
