Default Keeping coolant from freezing.

I was thinking about this today while changing the fluid in my bandsaw. How do you keep the fluid from freezing?

I moved the saw to the new shop and until business picks up I won't be heating the shop unless I am in it. Got me to wondering if I just tossed a half gallon of antifreeze in it if that would keep it from freezing?

Would not recommend auto due to the vapor . RV type to me would be better . But I am sure shade will check in on this it is his field. I have seen Fish heaters installed in a couple of tanks.

perhaps windshield washer fluid? I used to use it during cold weather marching competitions because valve oil for a trumpet gets too thick during cold weather. (yes I was a band geek) anyway we replaced the valve oil with plain old blue washer fluid, and it worked great.

First, do not add antifreeze to your coolant.

1. What coolant are you using?
2. How cold does your shop get?
3. Mixed coolant freezed below 32F and is chemistry and concentration dependant.
4. What saw do you have?
5. What kind of cutting are you doing.
a. Material type.
b. Material shape.
c. Number of cuts per hour/day?

Place I used to work...
First part of the winter we'd put a heavy tarp over the saw at night with a trouble light under it. Worked pretty good down to -10C
A little colder we'd throw one of them little electric heaters under the tarp.
When it got REAL cold ( -30C and lower) we would pour in a bunch of antifreeze... keep the coolant running all night, cover with the tarp and use the heater. Things would still freeze up down around -40.
Ya...the antifreeze isn't the greatest idea but it does work. Don't let yer dog drink outta the coolant tank.

1. What coolant are you using? (Not sure, I get it from a friends shop it looks white when mixed About 1 quart makes 5 gal)
2. How cold does your shop get? Usually water on the floor dosen't freeze until early feb (Coldest time for us)
3. Mixed coolant freezed below 32F and is chemistry and concentration dependant.
4. What saw do you have? Royal 110 in blade. It is a rebaged cheapie but it weighs 900lb!
5. What kind of cutting are you doing. Mostly cold roll 1 inch thick and thinner
a. Material type. Cold roll steel
b. Material shape. rectangle
c. Number of cuts per hour/day? some weeks the saw runs all day sometimes it dosen't run for a week.

I thought about a feed trough heater but there is no way to get one inside the tank. I can get a large cup inside to clean it out that is all the room ther is.
