PCM is the future of efficient heat protection

The canicool PCM vest uses advanced Bio-Based Phase Change Material (PCM) technology to protect your dog’s body against heat safely and efficiently — without moisture, without dripping, and without temperature shock by providing a constant temperature of 21°C / 70°F or 29°C / 84°F

What is PCM?

Phase Change Materials (PCMs) absorb and release heat energy by freezing and melting at defined temperatures.

To understand why this is powerful, we need to distinguish between:

1. Sensible Heat

This is when a material warms up and its temperature increases.
Example: A glass of water in the sun gets warmer. The temperature rises continuously.

2. Latent Heat

This is when a material changes phase (solid ↔ liquid) but keeps the same temperature during the process. Example: Ice melts at 0°C / 32°F and stays at 0°C / 32°F until completely melted.

That stable phase transition is where PCM becomes extremely effective.

How PCM works in canicool PCM vest

When the ambient temperature rises above the PCM activation temperature:

  • The cooling modules begin to soften and melt
  • During melting, they maintain a defined target temperature
  • They absorb excess body heat without dropping below that temperature

As long as the material is in its active melting phase, it releases the same stable cooling temperature.

PCM

Phase Change Material (PCM) regulates temperature by absorbing and releasing latent heat during its phase transition. When the ambient temperature rises above 21°C / 70°F, the material begins to melt and absorbs excess heat while maintaining a stable temperature. As long as the melting process continues, the temperature remains constant.

When the surrounding temperature drops again, the PCM solidifies and releases the stored heat back to the environment. This cycle allows for reliable, controlled cooling without sudden temperature fluctuations.

How to Activate PCM Cooling Packs

1. Cool Until Solid Place the PCM packs in ice water (20 min), freezer (40 min), or refrigerator (60 min) until fully solid. The temperature must be at least 3°C / 5°F below the PCM activation temperature.

2. Check Firmness. Make sure the packs feel completely firm with no soft or liquid areas remaining.

3. Insert & Use. Place the solid packs into the vest pockets, secure them properly, and your dog is ready for stable, dry cooling.

Core features of the PCM Modules

2 Options

✔ Constant cooling at 21°C / 70°F for approx. 1–3 hours
✔ Optional version at 29°C / 84°F for gentler cooling and longer lasting.

As soon as ambient temperature exceeds 21°C / 70°F, the packs begin regulating at their defined temperature. Below 20°C / 70°F, the PCM automatically reactivates.

To accelerate reactivation, simply place the packs in a refrigerator. The process can be repeated up to 100,000 times.
