Comprehensive technical information on the physics of Phase Change Material (PCM) technology, its applications, and its role in the ArmorCell™ system.
Phase Change Material (PCM) refers to substances that can absorb and release large amounts of energy during solid-to-liquid phase transitions. This "latent heat" capacity makes PCMs far more effective than conventional sensible-heat materials.
A simple example: 1 kg of water absorbs 4.2 kJ to warm by 1°C. The same mass of paraffin PCM absorbs over 200 kJ during melting with zero temperature change.
This difference makes PCM usable as a zero-energy "thermal buffer", absorbing heat spikes without consuming electricity.
PCM in crystalline form. Heat starts to build from equipment or the environment.
PCM melts, absorbing thousands of kJ. Temperature stays flat — this is the key moment.
Energy stored. When the environment cools, PCM re-solidifies and the cycle begins again.
ICS selects the optimal PCM type for your application and provides a full engineering service.
Paraffins and fatty acids. Chemical stability, long service life, zero corrosion risk. Preferred for low-to-medium temperature applications (18°C – 44°C).
Salt hydrates. High thermal capacity and conductivity. For medium-to-high temperature applications (30°C – 60°C). Requires careful encapsulation.
A specific-ratio mix of two or more substances. Preferred when precision melting point control is required. Special project applications.
