INUTEQ-PAC Technology®

INUTEQ-PAC® represents the new generation in phase change cooling, offering revolutionary thermal management for situations where exact temperatures are essential. This advanced technology is built on a 100% bio-based, biodegradable Phase Change Material (PCM) that delivers safe, sustainable, and highly effective temperature control. Unlike traditional water or ice-based cooling, INUTEQ-PAC® provides a consistent and precise cooling output, engineered to maintain a specific temperature for an extended duration, ensuring optimal comfort and safety without the shock of extreme cold.

Water/Ice vs Phase Change Materials: The Smart Cooling Revolution

Traditional Water/Ice Cooling: The Limitations

Traditional cooling vests rely on water or ice, which operates at a fixed temperature of 0°C (32°F). While effective initially, this approach has significant drawbacks:

• Too Cold: Ice at 0°C can cause discomfort, skin irritation, and even hypothermia risks
• Short Duration: Ice melts quickly, providing only brief cooling periods
• Weight Issues: Water and ice are heavy, reducing mobility and comfort
• Temperature Shock: The extreme cold can be uncomfortable and distracting

Phase Change Materials: Precision Cooling Technology

Our advanced Phase Change Materials (PCM) represent a breakthrough in personal cooling technology. Unlike water/ice, PCMs can be engineered to activate at specific, comfortable temperatures:

• PCM at 6.5°C (44°F). Perfect for extreme heat conditions and high-intensity short activities. Provides powerful cooling while remaining significantly more comfortable than ice.
• PCM at 15°C (59°F). Ideal for moderate to high heat environments. Offers sustained cooling without the shock of ice-cold temperatures.
• PCM at 21°C (70°F). Excellent for office environments and mild heat stress. Maintains optimal body temperature during extended wear.
• PCM at 24°C (75°F). Perfect for subtle temperature regulation and all-day comfort in warm conditions.
• PCM at 29°C (84°F). Designed for preventing overheating in moderately warm environments while maintaining natural body temperature.

The PCM Advantage

The PCM offers the following advantages:

• Consistent Temperature: PCMs maintain their target temperature throughout the cooling cycle, unlike ice which immediately begins warming.
• Longer Duration: Phase change technology provides extended cooling periods, often 2-6 times longer than traditional ice packs.
• Comfort Optimized: No temperature shock or discomfort - just steady, pleasant cooling at the perfect temperature.
• Lightweight: PCM materials are significantly lighter (approx. 20%) than water-based alternatives.
• Rechargeable: Simply refrigerate or freeze to “recharge” the cooling power.
• Safe: No risk of frostbite or hypothermia from extreme cold exposure.

Choose Your Perfect Temperature

With our range of PCM temperatures, you can select the ideal cooling level for your specific needs, environment, and comfort preferences. Experience the future of personal cooling technology.

• Healthier and More Comfortable Cooling: Avoids Over-Cooling and Skin Damage: Ice melts at 0°C (32°F), a temperature that is too cold for prolonged, direct skin contact. This can cause skin irritation, redness, and even cold-induced injuries like frostbite. PCMs are engineered to melt at higher, safer temperatures, typically between 6,5°C (44°F) and 29°C (84°F). This provides a cool, comfortable sensation without the shock and potential harm of freezing temperatures. 
• Prevents Vasoconstriction: When the skin is exposed to extreme cold from ice, the blood vessels constrict (a process called vasoconstriction). This reduces blood flow to the skin, which ironically traps heat in the body's core and makes the cooling process less efficient. Because PCMs operate at a milder temperature, they cool the body without triggering this response, allowing for more effective and continuous heat transfer away from the bod
  More Practical and Efficient
• Consistent and Longer-Lasting Cooling: Ice provides a powerful but short burst of cooling. As it melts, its temperature rises, and its effectiveness quickly diminishes. PCMs, however, absorb heat and melt at a constant temperature, providing a steady and predictable cooling effect for a much longer duration, often for several hours. 
• Faster and More Convenient Recharging: PCM packs can be "recharged" (solidified) much more quickly and easily than freezing water into ice. Depending on the type, they can be reactivated by placing them in a refrigerator, freezer, or even a container of ice water for as little as 30 minutes. This makes them highly reusable and practical for people who need cooling for an entire workday or shift. 
• Durability and Reusability: PCM packs are durable and can be reused thousands of times without losing their effectiveness. They are typically sealed in robust pouches, eliminating the mess of melting ice.

The Technology

INUTEQ-PAC® is a smart cooling revolution driven by advanced Phase Change Materials. A PCM is a substance that absorbs and releases thermal energy during the process of melting and freezing. While water is a basic PCM that melts at 0°C (32°F), our technology utilizes a sophisticated, 100% bio-based PCM derived from vegetable origins. This material can be engineered to activate at several precise, medically safe temperatures.

This allows us to offer a range of cooling options tailored to specific needs: 

• 6.5°C / 44°F: For powerful cooling in extreme heat and high-intensity activities (for instance pre-post cooling for athletes). 
• 15°C / 59°F: Ideal for sustained cooling in moderate to high heat environments. 
•  21°C / 70°F: Excellent for maintaining optimal body temperature during extended wear.
•  24°C / 75°F: Perfect for subtle temperature regulation and all-day comfort. 
• 29°C / 84°F: Designed to prevent overheating in moderately warm conditions.

As the only USDA-certified 100% bio-based and REACH compliant PCM on the market, INUTEQ-PAC® sets the standard for high-performance, non-toxic, and sustainable personal cooling.

How It Works
The INUTEQ-PAC® technology provides consistent, long-lasting cooling through the physical process of phase change:

1.  Activation (Recharging): The PCM packs or CoolOver are “recharged” by placing them in a freezer, refrigerator, ice water or in a ambient temperature <3°C  than the PCM temperature until they become fully solid. 
2. Insertion: Once solid, the lightweight PCM packs, which are 20% lighter than water, are inserted into the pockets of the specially designed cooling vests. Alternatively, after activation the PCM CoolOver can be worn directly for immediate use.
3. Heat Absorption: As the wearer’s body generates heat, the PCM begins to absorb this thermal energy. This causes the material to slowly melt from a solid to a liquid.
4.  Constant Temperature Cooling: Throughout the melting process, the PCM maintains its exact, engineered temperature (e.g., 21°C / 70F). This provides a steady, comfortable, and predictable cooling effect without the sharp temperature drop associated with ice.

The cooling duration is significantly longer than traditional methods, often lasting for several hours.

Key Features and Benefits
INUTEQ-PAC® technology offers a clear advantage over traditional cooling methods, delivering a healthier, more practical, and efficient solution:

• Consistent and Precise Temperature: Maintains the exact chosen temperature throughout its cycle, providing predictable and reliable cooling without dangerous temperature shocks.
•  Healthier and More Comfortable Cooling: Operates at medically safe temperatures, avoiding the risk of skin irritation, frostbite, or vasoconstriction (the narrowing of blood vessels) that can be caused by ice.
•  Longer-Lasting Cooling: Provides a steady cooling effect for a much longer duration than ice, often for several hours per activation.
• Fast and Convenient Recharging: The packs or CoolOver can be fully reactivated in as little as 30 – 45 minutes in a freezer, or in any environment with a temperature at least 3°C lower than the PCM's activation temperature. This makes it highly practical for all-day use.       
• Lightweight and Durable: The PCM material is approximately 20% lighter than water and is sealed in robust pouches that can be reused thousands of times without losing effectiveness.
