Long-Lasting Cooling

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, so you get twice the cooling 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. 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.

Frequently Asked Questions

How long does the cooling effect last with the Cool Flow® System?

Cooling time can vary based on several factors, but many customers report 2–3 hours of cooling with the 9-quart system. The 16-quart system typically provides 4–5 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 area it's cooling, the ice or frozen bottles will melt. This is a sign the cooling is working.
Cycle Time: Longer cooling sessions will require more frequent ice or bottle changes. Always follow your healthcare provider’s recommended cooling schedule.
Cooling Setting: Higher flow settings (1–4) deliver colder cooling 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 Cool Flow® Systems are designed to hold standard 16 oz frozen water bottles, creating a larger, longer-lasting cooling source than traditional ice.
