The manufacturer is right there? REA, whoever they are...

This comes up on a Google UK search:

REA are American, I may have something on my Home PC.
Later if still unresolved I will have a look AlexG.

Thanks guys. But it doesn't look like US made chiller. It looks more Italian. Carel mChiller2 controller, Dorin compressors... Moreover on REA web site I didn't find any technical information. I suspect this chiller marked like AL-CO or AL-KO (not sure) but I doubt this is truth.

Hi Alex
Could be a Klimatechnik chiller!
From picture it looks industrial process set up so it may have been a bespoke model.

Hookster, you mean KTK Klimatechnik or something else?

I'm also inclined to think it's a bespoke system - look closely at the serial & wiring diagram no's.

That website I linked to says it's undergoing an upgrade, but the contact details are still there. A search of the model no. suggested one of the Italian co's http://www.ktk.it/Index.php?id=111&lang_id=eng&set_id=74&record_id=159

It seems JWH is also a synthetic cannabiod, from the fact that our model no. gives one bit on the front page, the rest being synthetic drug references! :O

Hi Guys.
I can find some REA chillers and even the corporate catalogue!
Check out the attached link to one of their sites.
So REA do exist!
I quote from their products manual.."
RAE Corporation wasfounded in 1971, as a privately heldcorporation. From thebeginning, the company has beendedicated to the manufacturing ofcompressorized equipment for therefrigeration, HVAC, and industrialmarkets. Our manufacturingfacilities are located in the 7,000-acre Mid-America IndustrialPark, 40 miles east of Tulsa,Oklahoma. RAE Corporation remainsa privately-held company,but today it functions with sixdivisions. Each of the six divisionsare involved in the HVAC andrefrigeration industry. The divisionsinclude Century Refrigeration,Refrigeration Systems, TechnicalSystems, RAE Coils, Air Cube,and King Coils. Thus RefrigerationSystems has the advantagesof both a dedicated sales,marketing,

So at a guess I would say the label shown may well refer to the coils and
as other say.
whether the chiller in question is a RAE?
Is anyones Guess!

I'm going with REA Grizzly, because that appears to be the manufacturer's name at the top of the right hand data plate. That the model & serial no's match on each label, and there's a reference to electrical data & the wiring diagram on the left hand label all point to it being an REA system to me. Custom built or what, I don't know.

Thanks again guys. Freezer is right, first what I found in internet googling JWH is drug. if it is really KTK, I already sent them request. I have a contact in KTK. One time I already contacted to them, after small discussion they replied. So I am waiting for feedback from them.
