Hi guys used isopropanol first time yesterday morning and no.freezing water ran fine even though was icing up on gooseneck and sills had no issues with water flow like normally would.

Only thing noticed seems to bubble up soapy like on glass is this normal and will it dry same? rinsed away fine but was just bit concerned?

Cheers

Had the same, didn't affect the PPM of the water though. It seems as if it needs to settles. Although it annoyed me so much I didn't put ISO in it again after the first time. Been -6 here and tank doesn't freeze and I've had no problems using it at work either. Just bring in my poles and hose reel every night when it's cold.

yeah annoyed me but was more concerned how it would dry but no complaints. be honest at first thought it was all bits and dust on glass until noticed little bubbles, if it keeps me working I will use when belw zero, cheers

Yeah all mine dried ok. Just made me over rinse to compensate for all the bubbles. Probably more psychological though.

 
Yeah I had same when I used it for the first time a couple of weeks ago.

Tried my own windows first and they came up well, had no complaints from the custys either. /emoticons/biggrin.png

I have used it last three years no problem at all .just stick to the amounts per litre specified and it is alcohol and has a vapor that may make you dizzy if you add too much

Hi. is half a litre ok for a 350 tank mate?

My tank has been frozen 3 times here under -6 according to weather forecast. It's a nightmare old curtains covering it now on a night lol

What size is your tank?? Not even my pump gave up. Granted it spluttered a few times during the day but I just turned the calibration up to give it a bit more oomph

I run a 325 compact...reel.is bolted to tank one issue in winter ...I'm looking for a boiler jacket or 2 to go round it next van I get I will insulate it out too

 
I've just had an email encouraging me to savour the delights of Isopropanol as an antifreeze for wfp.

 I can get 2 x 5 litres for £30 delivered on fleebay.

Good idea?

What sort of quantity would I need in a 350ltr tank?

 
I use it every winter. A decilitre in my 350l tank whenever I fill up. It helps a little, but it needs constant circulation if the temperature drops too much. Never experienced any trouble with the pump. Most are afaik made for pumping all sorts of chemicals thus a splash of alcohol in an entire tank will be so diluted it can't possible make a difference..

Every year this subject comes up. What I would call boardering on a scam text/email is sent out by a supplier to window cleaners on his data base to draw an unsuspecting windie in.

Have a look at the first block where Isoprop is used as an anti-freeze in water and the %'s required to achieve this.

https://www.engineeringtoolbox.com/ispropanol-water-d_988.html

If you want to protect your full tank of water to -4 degrees then you would need 10% Isoprop to 90% water. But again, what is the temp of the water in your tank at any given time in winter?

We don't live in the polar regions of the frozen north. I once tested the temperature of the water in my tank over a weekend in winter. I still had a good amount of water in my 650 liter tank when I finished on Friday. The tank was covered by an old duvet and I had an 800w frostat heater in the back set to come on at 2 degrees C. It switches off at 5 degrees C. The temperature of the water in the tank on Saturday afternoon was 9 degrees C.

Moving water freezes at a lower temperature as when water moves it generates a little heat. Its to do with the amount of kenetic energy in the moving/flowing water. The water in our tanks sloshes around as we drive so this could add to a little warmth being generated in the water and raising the temperature a degree or 2. (I have never tested this).

So if add a cap full of Isoprop to my tank in the middle of winter on the belief that it will solve my freezing concerns then I will be elated with what I perceive to be as excellent results.

I’ve just got a little heater in the van running off an extension lead going to a camping socket drilled into side of van. Had a pump split at the diaphragm because of the cold last year, I’m not putting anything in my water after spending so much money on resin to clean it.

 
Pure water has a lower freezing point than normal water and has been cooled to -48°c in a lab before freezing.

Purer than what we use but a few days of icy weather won't do much to it.

I never heat my van I just drain the pump and put a quilt over the tank.

Never a problem except for the odd icy pole hose

My son's van is just left to its own over winter. The pump is drained and so is the water in the tank. A little water is left in the bottom of the tank which freezes when we have a cold snap.

I have also had my van ports freeze up as well as the water in the hoses when I had a trailer system.

This is an interesting article;

Freezing Point of Water

The freezing point of water is the temperature at which it changes from a liquid into a solid. Pure or distilled water freezes at 32 degrees Fahrenheit (zero degrees Celsius). This is the same as the melting point when water goes from solid ice to liquid water. However, the freezing point of water may be lower if the water contains foreign matter that could trigger freezing point depression. Under some conditions, water may not freeze until it reaches a temperature of minus 40 to minus 42 degrees Fahrenheit. This is because water needs a seed crystal or nucleus – a tiny particle – to create a crystal structure around. If water is pristine, it can hold its liquid state until it reaches the temperature at which the crystalline structure forms.

 I didn't know that regarding the freezing of water although I do know a salt solution in the water will lower its freeze point ie the sea. I'm not sure our deionised water fits the catagory of "pristine". Its just pure enough to clean windows successfully without leaving deposits.
