Title: merlin - how fast?
Post by: ftp on November 02, 2009, 08:45:59 pm
That's it really - someone asked me about them today and I don't have a clue.

With good mains pressure usually around 100 Litres an hour  ;)

You need at least 40 PSI from the mains - which i understand is unlikely in the UK - well Norfolk anyway,  so invest in a good pump ( i mean a proper 24/7 running one! ) to boost pressure - mine is running a 75 PSI and will fill 250 litre tank in 2 hours 10 mins ( give or take )

TDS in is 380 IN   015 OUT -  di down to zero

hope this helps

I get 40 litres an hour maximum from my merlin (more usually low 30s though).  It operates around 35 - 38 PSI though and the standpipe that feeds it is a long way from the mains outlet.  I'm sure the 100 litres an hour quoted is perfectly possible under better conditions than mine.  Production gradually dropped to about 15 litres and hour for a while but a membrane change sorted that out.

in my opinion / circumstances , no
I had a merlin, waste ratio and product tds (un pumped) was bad. 370 in 30 out.
Now got an hf5 tds out is about 8 - 10 and I fill a 650 tank in 3 hours.
hope that helps

Sounds good, I have a Hf5 4040 and all the bits sitting here in my living room. Just hoping the merlin was not going to produce better.

Do you mind me asking what pressure your water is at?

Seems the 4040 produces very well then.

EZ Clean -

Pump cost around £160 inc VAT

will have to look up the exact name of supplier -  was something like Suffolk pumps  i know they were in Ipswitch and delivered next day

They were very good as i talked to them about the water pressure needed and what i was using it for

Merlin is def no good under the 40 PSI mark - but at the higher pressure works really well for me

I have the Merlin and can fill a 1000 litre IBC tank in approx 12 hours. It was quicker in the warmer weather for some reason.

46 psi pressure according to the gauge on the Merlin.

TDS in 70, TDS out 1.

Can someone explain to me the difference between the purefreedom merlin @£298 and Cleaningspots at @£263. The purefreedom one seems to have a few tubes running around the sides whereas cleaningspots just looks plain basic. Would that be it????????  ???

Yep, definitely temp related, it surprised me what a difference it makes. I have the tank / filter in the garage but the hose comes from around the side of the house atm.

Also...are these ok to connect straight into the van so as to produce water "on site" as opposed to making it at home???
Title: Re: merlin - how fast?
Post by: Smudger on November 03, 2009, 08:32:29 am
Dave likewise - outside tap around the house into the utility room to merlin back out to van.

I think you will find the cleaning spot one does not have all the related bits like pressure guage - post filter etc..

From what I can tell, the purefreedom pic shows what it looks like assembled with the hoses attached, the cleaningspot one doesn't.

Also, reading the description, the purefreedom one has a hoselock fitting included to attach straight to your supply.

I got mine from windowcleaningwarehouse £215 + vat.

No hoselock fitting but I just put the inlet hose into my supply pipe and put a jubilee clip over it.

I've one in the garage not use'd for couple of years so needs new membrains and carbon filter, free to collector
Title: Re: merlin - how fast?
Post by: Pole 2 Pole on November 03, 2009, 05:12:26 pm
If i was to use this from the van(ie on site) does this merlin still produce waste? I mean would i need to dispose of waste into a drain or on the street etc???? Please forgive my ignorance peeps x

From what I have learnt the merlin units are rather heavy on waste.
Title: Re: merlin - how fast?
Post by: Smudger on November 03, 2009, 05:24:09 pm
I would have thought any RO unit would produce waste that needs to be pumped away ??
