The stackable BlockVesl is a precisely engineered PCM device with more than 3,200 square centimeters of surface area. It is suited to a wide range of applications, including refrigeration, air conditioning, heat recovery and heat storage. One BlockVesl can store up to 200,000 joules of energy depending on the PCM selected.


The 305mm-diameter MacroVesl is a multi-chambered, high-capacity sphere with more than 24,600 square centimeters of surface area. That's more than 16 times the surface area of a typical sphere of the same diameter. It is suited to a wide range of applications, including air conditioning, heat recovery and thermal energy storage.


The MicroVesl features a multi-layered polymer structure chosen for its ideal barrier properties. The MicroVesl, now available in a diameter of 18.5 mm, can be made in a range of sizes and is ideal for use in refrigeration, air conditioning, thermal energy storage and many other applications.

What are phase change materials?

Phase change materials (PCM) are substances that absorb and release thermal energy during the process of melting and freezing. When a PCM freezes, it releases a large amount of energy in the form of latent heat at a relatively constant temperature. Conversely, when such material melts, it absorbs a large amount of heat from the environment. PCMs recharge as ambient temperatures fluctuate, making them ideal for a variety of everyday applications that require temperature control.
