Multi-Use Cold Therapy

The rectangular universal therapy pad provides excellent coverage for multiple body parts, delivering steady, drug-free pain relief directly where you need it most. Secure it to the desired area with elastic and Velcro® belts, sit or lay on it for effortless hands-free cold therapy, or slip it inside a pillowcase for added comfort. The insulated outer fabric directs maximum cold therapy to the target area while providing gentle compression for comfortable, effective treatment.

High-flow, dry, quick-disconnect couplings allow for freedom of movement when needed. Durable insulated tubing ensures smooth water flow, so unlike traditional ice packs that warm up quickly and slip out of place, the Active Ice® 3.0 circulates cold water continuously for hours, often through the night.

Personalized Cooling at Your Fingertips

Our patent-pending timer allows you to set custom cold therapy "on" and "off" duration cycles per your healthcare provider's instruction — a critical safety feature!

Choose from 4 coldness levels depending on your comfort and desire, and rest easy knowing the convenient on/off button eliminates any potential danger from fumbling in the dark to plug in or unplug your system.

Long-Lasting Cooling

One of the largest cooling reservoirs in the industry, available in a 9-quart or 16-quart size. The 9-quart holds up to six standard size 500 ml frozen water bottles while the 16-quart holds up to twelve — twice the capacity of our biggest competitors — so you get twice the cold therapy before needing a refill.

Frozen water bottles are a reusable, convenient alternative to ice that can be easily swapped out with a fresh set from the freezer once thawed, eliminating the need to drain melted water and making life easier for caregivers too. The hinged lid snaps firmly in place to keep everything sealed and mess-free. Simply add ice or frozen water bottles and you're ready to go.

Quiet Yet Powerful Performance

The whisper-quiet, high-efficiency pump continuously circulates cold water throughout the therapy pad, delivering steady, effective cold therapy without noise or interruption. Powerful enough to keep cold water flowing for hours, yet quiet enough to run through the night without disturbing your sleep.

Frequently Asked Questions

What’s the difference between the 9-QT and 16-QT Active Ice® Cold Therapy Machine?

Both systems work the same and include the same features, therapy pads, and programmable controls.The main difference is size and cooling time:9-QT: More compact with a flip carry handle, ideal when space and weight matter.16-QT: Larger cooling reservoir holds twice as many frozen water bottles, delivering about twice the cold therapy time between changes. Includes a retractable handle and wheels for easier transport.

How long does the cooling effect last with the Active Ice® Cold Therapy Machine?

Cooling time can vary based on several factors, but many customers report 6–8 hours of cooling with the 9-quart system. The 16-quart system typically provides 12–16 hours between ice changes.

Several things affect how long the cooling lasts:
Body Heat: Everyone generates different levels of body heat. As the system pulls heat away from the treated area, the ice or frozen bottles will melt. This is a sign the therapy is working.
Cycle Time: Longer therapy sessions will require more frequent ice or bottle changes. Always follow your healthcare provider’s recommended therapy schedule.
Cooling Setting: Higher flow settings (1–4) deliver colder therapy but use ice faster. Lower settings help extend cooling time.
Type of Ice Used: Frozen water bottles last significantly longer than loose ice. That’s why Active Ice® Systems are designed to hold standard 16 oz frozen water bottles, creating a larger, longer-lasting cooling source than traditional ice.

Is the Active Ice® Cold Therapy Machine suitable for post-surgical recovery?

Yes. The Active Ice® Cold Therapy System is commonly used for post-surgical recovery, post-injury care, and general pain management. It delivers consistent, localized cold therapy to help reduce swelling, calm inflammation, minimize muscle spasms, and provide drug-free pain relief. With a variety of therapy pad options for different body parts, it can support recovery for a wide range of needs.

How does the Polar Active Ice® Cold Therapy Machine help with recovery?

Our systems deliver consistent cold therapy with gentle compression while the insulated outer fabric helps direct maximum cooling to the targeted area. Cold therapy works by slowing blood flow to the injury, which may help reduce swelling, minimize muscle spasms, and support the body’s natural recovery process. All with effective, drug-free pain relief.

Why Should I Choose the Active Ice® Cold Therapy Machine?
  • Family-owned and operated small business based in Ohio, USA Designed, engineered, and assembled in the USA for quality you can trust.
  • Dedicated, on-site customer service team — we answer our phones and emails!
  • Manufacturing, engineering, and operations all handled in-house.
  • Programmable timer and adjustable flow control with 4 coldness levels. Set custom on and off therapy cycles per your healthcare provider's instructions — a critical safety feature!
  • Large cooling reservoir designed to hold frozen 16.9 oz water bottles instead of ice for longer-lasting cold, reusability, and no draining melted ice water.
Are Active Ice® Therapy Pads interchangeable between body parts?

Yes. All Active Ice® Therapy Pads are designed to work with the same control unit. If you already own an Active Ice® System, you don't need a whole new setup to treat a different area, just purchase a separate Therapy Pad. Click here to view all Therapy Pad Options.

life saver

My PT friend recommened this for my recent knee surgery. Oh my goodness, it has been a blessing with pain management. So easy to set up and use. I usually only have to change out the water bottles twice in a day and I love I can choose the amount of time and cooling with the remote. I'm having the other knee done soon and I'm looking forward to the same benefits and healing with this knee.

This 16 qt. model has more than enough capacity to last all night without having to change out ice water bottles. I only use 6 at a time and it's perfect. Never have to drain out excess water or add any. Very easy to use

Really Helpful!

Highly recommend after knee replacement surgery! Eases pain and swelling no need to constantly change out ice packs. I thought this was essential for pain management and comfort! Purchased with FSA account thru work. Do it!

Amazing!

the three of us, my husband, my father, and I have had one shoulder replacement and three total hip replacements. We got an earlier version of this for the first joint replacement, and it helped SO much with pain control and speeded up the recovery process. We've been recommending this product/earlier version to everyone we run across who is considering surgery.

I had a 4 hour ride home after my knee replacement and was in a level 8 pain no matter what I took for how I sat. When I got home and elevated my leg and hooked up the ice machine. Instant relief. I highly recommend this machine.

Very good product

I have been using the Active Ice unit non-stop since returning from the hospital 9 days ago. Working great so far to help control swelling after my total knee replacement. I ordered the larger size cuff with it and am able to completely encircle my knee which is very nice. The only suggestions for improvement of the product I can think of would be to offer shorter or different sized cuff elastic and velcro bands (shorter would be nice in my case), and add a gasket of some sort to the cooler lid to prevent splashing out water when the unit is moved from one location to another (bedroom at night to living room during the day). Otherwise I highly recommend this product! Thank you!

Great System

Hello from Canada! My wife had bilateral knee replacement surgery in May 2024. In the weeks previous, I had researched various cool therapy systems from many different manufacturers. After watching a YouTube review by physiotherapist "Dr Sam”, we were convinced that the Polar Products Active Ice® 3.0 Double Universal Rectangular Cold Therapy System was the best choice for her post-surgery use. This full system came with the 9-quart reservoir, the two large rectangular cold therapy pads, a total of 4 long Velcro-style straps, the 2-pad to 1-reservoir Y-adapter hose assembly, the power pack and the timer controller. Setup of the 2-pad system was very intuitive. In literature she received before the surgery, the hospital requested that orthopaedic patients bring their own cold therapy equipment with them for starting the recovery process. While she was in hospital, a large absorbent pad provided the isolation from each cooling pad coming into direct contact with the skin around each knee, and only one long Velcro strap was needed to wrap twice around each knee to hold each cool therapy pad in place. The medical staff at the hospital had never seen the Polar Products Active Ice® 3.0 Cold Therapy System previously, and many positive comments about the system were heard during my wife’s 4-day stay in hospital. During her hospital recovery, the hospital provided cubed ice for the cold system reservoir. At home, the large rectangular cold therapy pads gave us the opportunity to re-work the cooling system setup, allowing each rectangular pad to become either the top or bottom of a "double-knee sandwich”. One cold therapy pad with a large absorbent pad above it was placed under both her knees, and a large rolled bath towel her knees lifted the middle of the lower rectangular pad to get better contact with the skin. Then another cooling pad was placed above another large absorbent pad covering the top side of both knees. This setup made it more convenient to get the cold therapy system started up and stopped whenever it was needed. At home, we used frozen 0.5 litre water bottles in the system reservoir. We both feel that for her recovery immediately following surgery in the hospital and later in the home environment, the two large rectangular cooling pads with the Polar Products Active Ice® 3.0 Cold Therapy System provided the most practical, convenient and flexible option for pain and swelling mitigation following her knee replacement surgery. We give this Polar Products Active Ice® 3.0 Cold Therapy System a total of "4-Thumbs Up”! - Irma and Jordan M., Winnipeg, Canada

Excellent Product!

I had used a friends cold therapy system before and found it exceptional, so much so that I purchased one for myself and have suggested to others that they purchase one for post knee replacement surgery. It truly is a lifesaver, minimizing pain and inflammation and very easy to use. Thanks for an excellent product!

Works

Multiple arthritic joints. Ice pack gels were getting too inefficient to use. Was referred to Polar from a friend who has shoulder surgery. His physician sent this system home with him as post surgery pain management. All I can say is, if you’re at all interested in this icing system, don’t hesitate. It’s very effective. Works exactly as promised.

Reduced pain of surgery

Hip replacement recovery is being helped greatly by the cold water system. Have used it for back pain, too. Your prep should include setting aside enough plastic bottles to freeze water in. This makes for neat and fast replacement.
