Body Cooling Systems What is the difference between the many different types of body cooling systems available? There are many different cooling products available and the best one for you depends on your personal situation, activity and environment. We recommend you consult your health care professional prior to purchasing a cooling garment or system. A summary of the systems: Evaporative Cooling Power: Low*         Cost: Very Low (*depending on humidity and outside variables) Cold packs Cooling Power: High               Cost: Low to Medium Phase Change Cooling Power:  Medium         Cost:   Medium   Active Cooling Cooling Power: Very High  Cost:  High to Very High         Evaporative Cooling: These products come in an assortment of garments that fit a wide variety of locations on the body. They are soaked in water to charge special polymer materials built into the garments. As the water evaporates (over many hors), the garment provides surface cooling. These systems are typically low cost and light weight. Advantages Low cost, light weight works for an extended period of time Disadvantages requires wetting of garment loses effectiveness in higher humidity Take me to MSolutions Evaporative Body Cooling Systems - low cost & effective        Cold Pack Cooling: These products typically come in vests, neck coolers and wrist coolers. The products work by incorporating cold packs into pockets of the wraps. The cold packs are placed in a freezer or a refrigerator until ready for use and then are placed in pockets designed into the wraps. The packs will provide cooling for up to 4 hours depending on environmental conditions and activity. Advantages medium cost, no wetting required effective for up to 4 hours, highest cooling capacity works in all environments adjustable cooling with more / less packs extra packs easily carried for extended cooling Disadvantages requires access to freezer / refrigerator requires time for packs to freeze medium weight: 4-5 lbs.                             Take me to Kool Max cold pack Body Cooling Systems - Best Value! Phase Change Cold Pack Cooling: These products are similar to the cold pack systems only use a phase change polymer in the cold packs or the garment. This technology controls the release of temperature to a specific range through out the cooling cycle. A typical temperature is 58 degree F. Phase change cold packs may be recharged in the freezer, refrigerator or in ice water. The packs will provide cooling for up to 3 hours depending on environmental conditions and activity. Advantages charges in ice water, refrigerator, freezer wetting not required, effective for up to 3 hours provides moderate cooling temperature works in all environments extra packs easily carried for extended cooling Disadvantages Higher cost system, high cost of spare packs Lower cooling efficentcy than cold packs medium weight: 5-7 lbs. medium cooling capacity Take me to MSolutions Phase Change Body Cooling Systems - Comfortable Cooling! Active Cooling: These products typically incorporate a coolant, often ice water, that is circulated from a reservoir by a pump system through channels or tubes embedded in a vest. Often a hood for the head is incorporated into the system also. The temperature of the circulating coolant usually can be adjusted. The system operates on batteries, house or car current. This type of system will provide many hours of cooling before the ice and water needs to be recharged. Advantages Most effective cooling - core body cooling adjustable cooling temperature extended cooling time between recharges no wetting required, works in all environments light weight garments Disadvantages very high cost system tethered system limits mobility requires ice water reservoir Take me to Soft Ice Active Cooling Systems - best value active system available!
