Tempered water for portable RO?

Specialties Urology

Published

Where do y'all get incoming water for portable treatments from? All my hookups are from the cold water side and the water is COLD! Usually around 18C this time of year which is okay per mfg specs, but below or checklist min of 21C. I don't see the hospital adding a blending valve to all the hookups, but I don't know how else to get the incoming water to a passing temp. Any suggestions? Do any portable RO's have an integrated heater? Thanks!

Okay, I looked at this some more and I think our checklist is wrong. 18C is a great temp for both the RO and the HD machine, and our upper limit is way too high.

I remember that I had a problem once when the water was apparently too cold because it made some membrane freeze in the machine and as a result the machine heated up the temp of the lines. When I noticed that the temp of the machine was getting above 37.5 C I called the HD technician who figured out it was because of the cold water. I had to terminate HD because the cold water came from a special hook up in the wall with just cold water and hook up old fashioned to the regular sink and the tech person mixed a tiny bit of warm water in. Of course that is expensive and I was told before to never run even a bit of hot water because I would strip the whole hospital of hot water lol.

You should bring your problem to the manager.

I know our machines have a heater on them but not the RO's (of course our RO's are soooooo OLD that our new educator didn't even know that carbon granular tanks still existed!)

What's in the carbon tanks now?

All the HD machines heat - but the RO does not

Our RO's have a 6 foot line from the water box to the RO. Couldn't you coil part of the line to fit in a wash basin and add hot water? Or wrap part of the incoming line in an aqua K heating pad?

I never had this problem when I was doing acutes, and I travelled to some very cold climates. I do remember a Biomed tech telling us to never mix hot water in -it would damage the R/O and the machine.

We have 20 year old Zyzatech Carbon granular tanks in the majority of our portable RO's. The type you have to backwash for 10-15 minutes each tank. Some of ours have the newer carbon block filters (looks like a giant fridge filter) LOL

Update:

My biomed talked with her boss and we all agree the water temperature is fine, the logs are wrong.
