HeatStaxx® Energy storage solutions for mobile applications

HeatStaxx® is a high performance macro encapsulation realized with custom-made blow molded synthetic material and specifically developed for mobile heat storage systems. The macro encapsulation design allows for a combination of a large surface and the smallest possible PCM layer thickness enabling the entire PCM module to run through the phase change process. This leads to high efficient heat transfer (quick charge and discharge) even at very low temperature variations. The signature shape guarantees a maximum heat transfer coefficient at minimum pressure drop culminating in superior charge and discharge performance. The charging time is being reduced significantly so that HeatStaxx® can be integrated perfectly in a wide range of mobile applications.

  • Utilise the potential of waste heat in a flexible and effective way: at biogas plants and industrial processes
  • Turn your truck into a heat delivery vehicle and serve e.g. schools, hospitals or hotels in your neighbourhood
  • Benefit from the Module Mobile’s storage capacity of 1.4 to 1.9 MWh (depending on temperature level) 
  • Rely on the macro encapsulated PCM modules with its long-term cycle stability to steer your performance output
