Keeping Ice Longer
Sure, there may be numerous reasons to buy a cooler. Latest features like recessed latches, built in bottle open (never look for the opener again), Off road wheels & lift handles to lift and pull your cooler anywhere, or maybe it just the looks. ROC coolers has them all..
Of course if you are looking at a rotomolded cooler you are looking for performance / ice retention. With up to two inches or more of insulation in the walls and lids of most sizes, combined with a freezer-quality sealing gasket and one-piece construction, ROC Hard Coolers provides industry-leading ice retention. Yet, if you’re asking what you can do to keep your cooler cold the longest, use these 7 tips below.
7 TIPS TO KEEP ICE LONGER IN YOUR ROC HARD COOLER
1. START WITH A CHILLED COOLER
If stored in warm places, a significant amount of ice will be wasted cooling the cooler itself. Preload your cooler a few hours prior to use with a sacrificial bag of ice to cool it down or store it in a cool place before loading it up.
2. USE TWICE THE ICE AS YOUR CONTENTS
Making sure you use enough ice in your cooler is key. We recommend following a ⅔ ice, ⅓ contents ratio. This means that one-third of your cooler can hold your cold drinks and food, while the other two-thirds should be filled with ice if you fill the cooler completely. The more ice you use, the longer it will last.
3. BLOCK ICE VS. CUBE ICE VS. DRY ICE
Smaller, cubed ice will chill a cooler and the contents more quickly, but block ice melts at a much slower rate. Most pros use a mix of both to chill contents and achieve long-term ice retention to keep their cooler cold the longest. Dry ice is a great way to keep the ROC hard cooler colder longer. While the ROC hard coolers are dry ice compatible or soft coolers are not.
4. AIR IS THE ENEMY
Large areas of air inside your cooler will accelerate ice-melt as the ice is consumed with having to cool the air, instead of your contents. If you do need to leave space in your cooler, they are best filled with extra ice.
5. DON'T DRAIN THE WATER
Once your cooler is in use, DO NOT empty the cold water. The water helps to insulate the remaining ice. However, exposed food and meat should be kept out of the water.
6. SUNLIGHT IS A HEAT SOURCE
Keep your cooler out of direct sunlight when possible. Ice can last up to twice as long in the shade. Some pros even use tarps or towels to cover their coolers when they can’t find a shaded spot.
7. LIMIT COOLER ACCESS
Every time you open the cooler, you are exchanging the cold air inside for warm air outside that must then be cooled, causing faster ice-melt.
