Glacier Ice Block Residential Pool Cooler

The Glacier Ice Block pool cooler is a perfect solution to uncomfortably warm water for medium-sized residential pools. Glacier swimming pool chillers are designed to solve the problem of hot pool water by taking the heat out of the water, and cycling the cool water back into your pool. Depending on the size and finish of your pool, the cooler can lower its temperature from 10 to 15 degrees Fahrenheit in 12 to 14 hours (note: pool finishes and bottoms that absorb heat more readily, such as quartz or dark tile, can take longer to fully cool). You'll never see it on your utility bill, but you will see it on your friends and family's faces when they're splashing around in your cool and refreshing pool in the peak of summer!
Ice Block Features:
  • Recommended for pools from 8,000-20,000 gallons
  • Efficiently cools 30 gallons per minute
  • Saltwater pool friendly
  • Limits evaporation for savings on water and chemicals
  • Easy installation and maintenance
  • Runs with your pool pump and automated systems
  • Optional temperature controls for manual pool systems
  • Energy efficient – Electric powered (low amperage output) 110/115V 8.5 Amps 60/50Hertz
  • Single inlet/outlet lines (1.5" diameter)

Glacier Pool Coolers are the best solution to uncomfortably warm pool water because:
  • Glacier Pool Coolers is a fan based system, not a heat pump/heat exchange unit. The Glacier system does not need Freon or gas.
  • It is easily incorporated into your existing pool plumbing system and automated control systems OR can be installed seamlessly on a new build.
  • Glacier is the original fan based swimming pool cooling system, trusted by pool owners around the world, and is the only patented system of its kind.
  • It costs pennies a day to operate. Residential models require an average of less than 10 amps; you'll never see it on your electric bill.
  • Not only will your pool be refreshing during those hot summer months but your pool water chemistry will be easier to maintain.
  • A 10 degree drop in water temperature (95' to 85') can often see a reduction of 20-25% in chemical consumption.
  • It doesn't matter if you're in the high desert or the Deep South, Glacier Pool Coolers can cool any pool anywhere!
Like all Glacier coolers, the Ice Block works by taking water from the pool's filter and chilling it with the airflow created by the cooler unit's fan. The chilled water is pumped back into the pool through the cooler's returns.
The Glacier system was developed in Houston, TX where the summers can average 90% humidity. All technical specs are based on the research done in that climate. The Glacier product line is UL tested and certified for residential and commercial use.
Glacier Pool Coolers are a solution that is affordable, efficient, easy to install, and inexpensive to operate. It's like an air conditioner for your pool!
Enjoy your cool & refreshing pool all summer long with the original, trusted, patented swimming pool cooling system!

What are the measurements around the bottom of the gpc-25, on the outside?
A shopper on Mar 18, 2017
BEST ANSWER: The GPC-25 is 52" tall and 34" in diameter. This would make the circumference around the outside approx. 106" at the widest point.
I live in Phoenix and have a swim spa (1500 gal) which I can't use over the summer months. The spa needs to be cooled to 85 for safe aerobic swimming , is this possible and do you have any customers who have done this?
BeyondForm on Mar 8, 2020
Are there installation instructions? How do I pipe it in?
Andy on Mar 19, 2019
BEST ANSWER: Can you get installation instructions before buying?
I am curious if this pump actually cools the water itself or cycles in cool water from the ground? I live in AZ so there is no cold water to be had in the summer time.
mindy on Aug 5, 2019
BEST ANSWER: This cooler does not bring in water from elsewhere. The cooler just circulates the pool water across a medium where airflow across the medium cools the flowing water. The cooler depends heavily on the temperature of the outside air. I have not yet cooled my pool lower than the air temperature, so I don't believe there is any evaporative cooling taking place. The cooling is direct air cooling, which is why it works best overnight when the air is cooler.
Does this Glacier Cooler make any noise like the pool pump? Is it quite or loud?
A shopper on Jul 7, 2020
BEST ANSWER: The only noise it makes is the fan on the top of the unit which is pretty quiet. You can also hear the water dripping down through the element on the inside. This too is also very quiet. Biggest issue is adjusting the water flow going in with that being pumped back out. It's a bit temperamental but once adjusted works great. Unit cools our water 6*-8* when run at night when the temps are cooler. We only run for about 8 hours at night and then shut it off during the day. It isn't needed every night.
Can this cooler get my spa down to 40degrees?
A shopper on Aug 4, 2016
BEST ANSWER: I use my chiller on a 25000 gal pool, it brings my pool down from 94 degrees to 87 degrees overnight. That doesn't seem like a lot but, It the difference in a warm bath and a cool stream. Sorry I can't be of more help.
Can the unit be turned on and off?
A shopper on Jul 5, 2017
BEST ANSWER: Yes, ours came with a switch pre-wired into the system. Then, we wired it from our circulation timer which gives us an easy timer option in addition to a manual off option.
Can this be operated at night with the auto
cover closed and still cool?
Steve on Jul 14, 2020
Is it true that it can be used only at night?
A shopper on Apr 25, 2019
BEST ANSWER: The cooler can be used any time of the day, but it is an evaporating system that relies on the natural cooling of water evaporation through the system. As it is not a heat pump, it is not a strong enough process to fight the heating effects of the sun. I run mine at night as soon as the sun goes down and manage to get about 5 to 6 degrees of cooling a night in the brutal Florida sun. It is a waste of energy and time to attempt to cool the pool during daylight hours regardless of the size of the pool.
can i add it to a pool that already has a heat pump?
salty on Jul 6, 2018
BEST ANSWER: Yes, I added it to a pool that has a gas heater, it really doesn't matter what you have as it is plumbed completely independently from the rest of the pool gear. I live in Florida and mine brings my pool down 6 to 7 degrees a night even though it is in the 90s here now.
What voltage is required?
Christopher S on Jun 14, 2021
BEST ANSWER: The chiller needs 110 V.Enter an answer to this question.
Can u hook this chiller up to a variable speed pump ?
A shopper on Jun 30, 2019
BEST ANSWER: You could I am sure, but the volume of water that flows through it drastically changes the way it cools the pool water so i would suggest that you set the inflow and outgo valves at a certain speed and only run it on that speed as it will not work as well if the volume of water changes as the speed changes.
Are you able to recommend any installers in Virginia? We live in Urbanna, VA?
JohnP on Feb 20, 2019
BEST ANSWER: I used my pool contractor, I could have easily plumbed it myself but they were doing a new pool install so I had them do it. They are a local company only; I am sure any of the maintenance franchises like pinch-a-penny (they would have done it here) or the others could easily do it as well. It comes with installation instructions that are very easy.
can this be used with an above ground pool? Mine is 18' diameter by 54" deep. Also can it be turned off in the winter months?
A shopper on Mar 31, 2018
BEST ANSWER: I am sure you can as long as it is plumbed into the system correctly. I had my pool company plumb it, but I could have done it myself. The adjustments to get the flow in and out of the unit takes a bit of getting used to, but once I got it set for my pool it runs fine and doesn't need to be set again. Being in Florida we compete with brutal sun and long days but I can get my pool down about 7 degrees a night and if I run it for a couple of days (at night only) I can get it down about 10 or 12 degrees pretty easily. During winter you simply empty it and I cover it so no leaves get in it. i will see how it runs this summer after a season off, but it should be fine.
btu rating of chiller?
A shopper on Mar 21, 2016
BEST ANSWER: since it is an evaporative cooler , I've never seen a btu rating. However, in Dallas, this cools my pools by about 6 degrees if I run it t night, this keeps the pool between 84 to 88 vs 90 to 96 before I installed it

Hope this helps
So, I have a 14k pool. I'm concerned about running this at night 10 hours then the pump to also run 8 hours during the day. That's a lot of work on the pump. Would it cool faster if I get the 30,000 gal. cooler and only used it 5 hours at night. Would that also work or does it have to run 9-10 hours? Thanks
Jerry L on Jun 26, 2020
BEST ANSWER: It's not necessary to run the cooler at night unless you're in 100+ degree weather for a week or more. If you're running your pump 8 hours per day you can split your run time to 4 or so hours early AM (3-7) then again 4 or 5 hours in the daytime. Remember, you're only doing this during high heat weather. 90 deg water is refreshing in triple digit weather.
Will this work on a 26,000 gallon pool or would I need to step up to the GPC210?
Brandon D on May 14, 2019
BEST ANSWER: Step up. Larger in this product is always better. Especially if it’s a play pool or pebble tech
Does this cooler work reasonably well in high humidity environments? My pool is about 18,000 gallons (salt system) and in direct sun most of the day. Location is Texas Gulf Coast near Galveston.
George K on Jun 25, 2017
BEST ANSWER: Yes, I live in Kentucky and gets very humid here at times, I've had mine for 5 yrs. just like most have stated, it cools pool from 6-10 degrees cooler. My pool is approx 18500 gals & im direct sun all day.Today temp here is 96, 60% humidity & 78% dew pt, let's just say very hot & pool temp is 88 degrees which to me is perfect. The main thing is make sure it gets installed correctly & very level. I highly recommend it, esp in your climate.
Hi, will the Glacier GPC-25 work with a Pentair IntelliproXF CSF Variable speed and flow pump? i'm wondering if there will be issues adjusting\setting the water flow with the pump being variable speed?
Thomas B on Sep 3, 2020
BEST ANSWER: Hello Tom, while we have several of these coolers installed and they work extremely well, none of our installations are operating with a variable speed pump. However, I cannot see this being a problem, since they operate on much less than the available water flow anyway. Besides, these coolers have a pump with a float in the bottom of them that kicks on and off as necessary.
Is it noisy?
Dan H on Jul 12, 2020
BEST ANSWER: It sounds like your air conditioner - you run it at night so not an issue
Can u hook this chiller up to a variable speed pump ? how do u deal with the variable rpms the pump runs at ?
A shopper on Jun 30, 2019
BEST ANSWER: We have a new VSP and have one of the settings programmed just to run the chiller at night. We use that program and then switch back to normal operations afterward.
What temp drop can I expect for a 15 gal in ground salt water pool ? Live in Houston Tx. Temps are 95-100. Pool is no longer refreshing!!
Greg on Jul 26, 2018
BEST ANSWER: I get 5 to 6 degrees a night, sometimes more, the the brutal Florida heat in a 20,000 gallon in ground saltwater pool.
What is the electrical needed for hookup?
A shopper on Jun 29, 2018
BEST ANSWER: One standard 110/115 v outlet is all it takes. It can be hard wired into an automatic system or just plugged in.
What is the flow rate of water through the unit?
A shopper on Jun 1, 2018
BEST ANSWER: I have my pump set at 2500
We live in north central Kansas, so in addition to summer heat and humidity (our water temp is 92 today), our winter temps can (and do) drop below 0 degrees at times. What is required for winterizing?
A shopper on Jun 17, 2021
Do you have this in stock?
A shopper on May 10, 2021
My pool is 8550 gallons and does not have a pool cage. I live in Florida where it gets very hot pool temp is usually 92-95 most days. Will this keep the pool temp lower during the day if running it for 8 hours every day?
Craig B on Aug 9, 2020
This mentions humidity, but how will it work on a large above ground pool in a very hot, dry area?

I tiled my pool instead of plaster and the surface and water gets really warm in Arizona - Phoenix area. I have had the Glacier chiller for 4 summers now it works great! It really cools the water great and would cool it too much if I kept it running.

Satisfied Customer!
No more bath water temps! This has been such a great investment as our pool generally stays around 90-95 degrees all summer! We have gone through several summers not using our pool at all! The Glacier Pool Cooler did as promised and lowered the temp to 85 degrees over night! We now maintain it at about 82 degrees, which is perfect for us!

works good
I live in Georgia and my pool water gets too warm. This cooler works well to reduce the temp - I wish it would reduce it more, but it does enough to make it more enjoyable.

The product works as described after installing it and setting the valves which was not that difficult, the manual operation is the only draw back all though its not a issue turning valves to isolate the chiller from my low speed pump operation I would recommend to pool owners if you are looking for total set it and forget it type operation make sure you have a automation type valve set up I may redo my piping and controls at a later date but for now I am very pleased, I hope that when I need replacement part down the road it won't be a hassle getting them form Glacier.
I would recommend this if you have water in the 90 and above, this unit and a rain shower makes it 80 degrees on a hot Humid new Orleans day!

I have the 30 GPM model on a 15,000 gallon pool. The cooler will chill the entire pool to the outside air temperature overnight. Typically, I am dropping the temperature from about 90 degrees F to 80-85 degrees F. I'm sure if the night air were colder that it would cool more, but this 5-10 temperature drop is very refreshing.

Works Great! Cools the Pool.
We love the Glacier Pool Cooler. We live in San Antonio and our pool water reached 96*. It was like taking a bath and not refreshing on a hot Texas day. We ran the cooler the first night and it dropped the temp 8 degrees. We didn't run it during the day and the temp crept back up 4 degrees. We ran it the second night and it dropped to 82 degrees. We run the cooler every two or three days based on how hot it gets during the day. This equipment works as stated. We can enjoy the pool on hot days now.

Best pool investment that l’ve made. Cools pool down 10 to 12 degrees over night. Runs all summer and doesn’t run up the electric bill.

Great for in ground pools in hot weather areas.
One of the best investments one can make for summer swimming in a hot geographical location. I’m in PHX and without this product pool was at 97 degrees. Too hot to swim in. Not to mention at that temp water chemistry and chlorine use was astronomical.
The Glacier system takes the water down to 82 which in the heat of the day is perfect. Very economical to operate. Highly recommended.

Amazing company!
I actually had to cancel my order for this, but I just want to say that pool supply unlimited has the greatest customer service! I canceled my order, and the chiller was still delivered to my house so I refused delivery. I called them and they refunded my money, and didn’t even charge the shipping even though it was a giant piece of equipment. I would absolutely order from them for any other product moving forward!

Glacier Pool Cooler - North Carolina
This is the best investment you could ever make if you like to swim in refreshing water in the summer. We could not use our pool in the summer in NC because the water would be 90+ degrees. Running this cooler at night brings our pool down 10 degrees and allows us to enjoy the pool for 2-3 days before reaching the need to use it again. Great investment...highly recommended.
