Heat Stress Protection Using PhaseCore

Standard Basic Cooling Vests are a great solution to reduce and combat heat stress. Standard Basic Cooling Vests use PhaseCore, a phase change material (PCM), to provide a cooling effect to the body's core by absorbing body heat. The Standard Cooling Vest has a two-piece, over the shoulder design that makes it extremely comfortable when worn under another vest or when sitting.

Users: Law Enforcement Officers, Automobile Drivers, Wheelchair Users, Industrial Workers, X-ray Technicians, Surgeons, Custodial Engineers

Includes: Vest (Mesh, Polyester, or CarbonX), Set of 16 - PhaseCore 28 or 32 Elements

Standard Cooling Vest Highlights

• Recharges at Room Temperature
• Recharges without Ice, Water, or Refrigeration
• Lightweight and Comfortable Design
• Machine Washable
• Effective up to 3 hours
• Easy to Use and Maintain
• One Size Fits Most
• Non-Toxic

Additional Information

How does it work?
Standard Cooling Vests are fitted with a set of 16 - PhaseCore 28 or PhaseCore 32 elements, which have an activation point of 82.4°F (28°C) or 89.6°F (32°C), respectively. When the body temperature rises above this point, the elements begin to absorb body heat. When heat is absorbed, the PhaseCore elements provide a comfortable and soothing cooling effect. Standard Cooling Vests hold PhaseCore elements close to the body allowing them to absorb heat most effectively.

Is it effective?
Tests completed in a hot environment have proven that PhaseCore technology is effective in helping to combat the rise in a person's body surface temperature when in a hot environment. Standard Cooling Vests are effective for up to 3 hours, actual time varies based on physical activity, body type, and the environmental conditions.

How does it recharge?
Standard Cooling Vests can be recharged by storing the PhaseCore elements in an environment less than the activation point. PhaseCore elements can be recharged more quickly in colder environments. Refrigeration is not required, but will make the recharge period shorter. PhaseCore elements are completely recharged when they return to a solid state. PhaseCore is simple, safe, and reusable.

Additional Information

How does it work?
PhaseCore 28 elements have an activation point of 82.4°F (28°C). When the ambient temperature rises above this point, the element begins to absorb heat energy and transforms from a solid to a liquid. PhaseCore 28 elements will remain at its activation point as the heat energy is absorbed and stored. When heat is absorbed, the PhaseCore elements provide a comfortable and soothing cooling effect. PhaseCore elements recharge and return to their solid state when the ambient temperature drops below the activation point. PhaseCore 28 elements have a 10 year or 6,000 cycle life.

Is it effective?
Tests completed in a hot environment have proven that PhaseCore 28 technology is effective in helping to combat the rise in a person's body surface temperature when in a hot environment. PhaseCore elements are effective for up to 4 hours, actual time varies based on physical activity, body type, environmental conditions, and garment.

How does it recharge?
PhaseCore 28 elements can be recharged by storing them in an environment less than the activation point of 82.4°F (28°C). PhaseCore elements can be recharged more quickly in colder environments. Refrigeration is not required, but will make the recharge period shorter. Use of PhaseCore elements after refrigeration or freezing can prolong and enhance the cooling effect. PhaseCore elements are completely recharged when they return to a solid state. PhaseCore is simple, safe, and reusable.

PhaseCore 32

The Solution to Personal Cooling

PhaseCore 32 is a non-toxic, non-flammable phase change material made of a salt mixture that is a sealed inside of a special wrapper. It changes from solid to liquid and back again depending on the surrounding temperature. PhaseCore 32 Elements are not effected by humidity and react to direct heat above its activation point. Garments in a variety of cuts and materials are designed to utilize the higher activation point cooling effect of PhaseCore 32 Elements to reduce heat stress.

PhaseCore Element	Non-toxic, non-flammable salt mixture sealed inside an aluminum wrapper.

Additional Information

How does it work?
PhaseCore 32 elements have an activation point of 90°F (32°C). When the ambient temperature rises above this point, the element begins to absorb heat energy and transforms from a solid to a liquid. PhaseCore 32 elements will remain at its activation point as the heat energy is absorbed and stored. When heat is absorbed, the PhaseCore elements provide a comfortable and soothing cooling effect. PhaseCore elements recharge and return to their solid state when the ambient temperature drops below the activation point. PhaseCore 32 elements have a 10 year or 6,000 cycle life.

Is it effective?
In extreme heat environments we recommend the use of PhaseCore 32 to cool the body. PhaseCore 32 will produce a cooling effect for a longer duration than PhaseCore 28 in extremely hot environments due to the higher activation point and high heat absorption capacity. PhaseCore 32 is recommended for users in environments greater than 110°F (43°C) for a prolonged period of time. In most of the products you can switch between PhaseCore 28 and 32 easily. Please refer to the individual product specifications for details.

How does it recharge?
PhaseCore 32 elements can be recharged by storing them in an environment less than the activation point of 90°F (32°C). PhaseCore elements can be recharged more quickly in colder environments. Refrigeration is not required, but will make the recharge period shorter. Use of PhaseCore elements after refrigeration or freezing can prolong and enhance the cooling effect. PhaseCore elements are completely recharged when they return to a solid state. PhaseCore is simple, safe, and reusable.
