I am trying to identify the connections on top of a plate heat exchanger - I have some photos which I can send anyone who might know, with dimensions. I have Googled but to no avail.
There are four, push-on fittings, each approx. one inch OD, each with two O ring seals, and a central thread between the two connectors on each end of the unit, presumably to retain the connector assembly.
Thanks, Nick
Can you put them on Photobucket or something?
Is there any sign of a manufacturer on it?
What's the problem? Are you trying to replace it or is itthat you have one and want to use it?
Hi Andy...
Thanks for the reply,
Don't know Photobucket but will find and see if I can...
There is various information on it, including what is probably the maker's logo but its a bit cryptic and Googling all the interpretations I can think of doesn't bring up anything useful.
I have one which I want to experiment with / convert my DHW cylinder to a thermal store so I can run the DHW at mains pressure and have a decent shower without pumps (ultimately)
Do you have a "suitable" e-mail address I can send to ?
Thanks, Nick
Really easy. Signing up takes one minute and is free.
I see.
Then the important things are
- figuring out which are the primary and secondary. You can find out the pairs (blow into one pipe), but not easily which is primary.
- which is input and which is output in each case
- Heat transfer capacity. You can get a rough idea from the size.
See if this site helps
It doesn't matter if the heat exchanger is oversized because you can regulate the heat transfer by setting the pump speed on the primary side.
Hi Andy, Sussed Photobucket, a picture follows.. A picture follows...
Well, I don't recognise the logo and tried obvious interpretations of it in ~Google (Suver, Suvep, Sunep,.....) no luck
What you could do is to count the plates and measure the size and compare with the GEA site. That will give you a rough spec. at least.
The other challenge is going to finding a suitable way to connect to the fittings.

Try "Swep".
Eq.
Impressive.
It looks like the Swedes own the plate heat exchanger market.
Looking up the model number E8N doesn't reveal anything, but E8T does as a heat exchanger for combi boiler. Perhaps this is an OEM version or something.
Anyway, I think that Nick could compare the dimensions and see if it all adds up except for the fittings. Like most of these types of device , dimensions are quoted with a thickness of some number plus N x another where N is the number of plates.
You'll still need a pump to drive water from the cylinder through the PHE (but you knew that anyway :-)
I used a GEA Ecoflex "Copper brazed plate heat exchanger model:- BP12M-20-G1G1"
Specification for 1 x M12-20-GG
Operational data: Side A Side B
Media: Water Water Condition: liquid liquid Heat exchanged: 50 kW Volume flow: 0.64 0.24 l/s Temperature inlet: 82 10 °C Temperature outlet: 63 60 °C Pressure drop: 29.65 3.91 kPa Surface margin: 1.49 % Content: 0.5 l Heat transfer area: 0.22 m2 Design pressure: 30 bar Design temperature: 200 °C
Design Data Height, Width, Length: 188 70 55 mm Insulation: none
This gives a good flow for most applications but runs cool whhen the bath hot tap is on full bore
Hi John,
Several interesting replies ...
It seems that it is a SWEP product and I have been browsing their site but this one doesn't seem to feature. Its size is approx 310mm x 75mm with about 25 plates vertically and if similar to the E8T, good for up to around 75 kW, so should do the job nicely.... assuming materials compatibility.
I think it might have been designed to be in a boiler and the connections are made into a block, so I may be looking for a boiler spare or have to get something made by someone with a lathe...
Anyway, thanks to all for some great info - I will see what SWEP come back with in a day or two hopefully and post the findings.
Nick
