Our products

The Axiotherm Phase Change Materials are designed to absorb and release large quantities of thermal energy at constant temperatures. Over 30 organic (ATP) and inorganic (ATS) high-performance PCM in a temperature range between -40 °C to 120 °C.  Upon request further melting temperatures can be developed for specific applications!

Key features of the AXIOTHERM® PCM are:

  • High heat storage capacities
  • Consistent, repeatable performance over thousands of thermal cycles
  • Simple and safe handling
  • Also based on renewable raw materials, nontoxic and biodegradable

Axiotherm PCM are preferably available in special macro-encapsulated form with an optimized surface-to-mass ratio for faster energy exchange and improved performance in practical applications. Standardised solutions such as our HeatSel®s and HeatPlates are available for water and air-based applications and can be adapted to your specific requirements.

HeatSels®

Specifically developed for water-based applications, HeatSel® is a high performance macro encapsulation based on customized and blow molded synthetic material. 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 ensures that each module (also within stacks of macro encapsulated modules) fully passes the water while optimally using the available space. The PCM capacity as well as its discharging and charging performance should be precisely adjustable to a defined temperature level across a large range to turn it into an highly effective element of complex systems such as technical facility structures  when used as part of latent storage solutions. Therefore HeatSels ® are used within a heat carrier medium (e.g. water) which results in an excellent heat transfer from the heat carrier to the PCM module. Guaranteeing for maximum dynamic, the hybrid heat storage concept makes HeatSel ® an ideal component for various applications within the fields of cooling, air Conditioning and heating technology.

The European Commission has acknowledged HeatSel’s innovation and market potential with entitling the product to become part of the SME-support programme, in which HeatSel® reached the top position in the “energy” category. Among 135 applications from European companies, ESDA named HeatSel® the most innovative idea in Europe.

Realized application

Cold storage system for Futurium

In 2017, AXIOTHERM equipped the Futurium with five state-of-the-art cold storage units totaling to a volume of 50,000 litres. Filled with 55,000 AXIOTHERM HeatSels their combined storage capacity amounts to 1 MWh: Possibility to reduce peak performance during events and to “charge” the units during financially advantageous tariff hours > with smaller refrigeration maching! 


HeatStaxx®

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
HeatStaxx® Air

Designed for air-based applications, HeatStaxx Air is a high performance macro encapsulation  made of specially tailored blow molded synthetic material. 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. As the signature shape guarantees a maximum heat transfer coefficient at minimum pressure drop, AirStaxx Air works excellently in air conditioning systems.

Easy air conditioning by taking advantage of even smallest temperature variations:

  • easy air conditioning by taking advantage of even smallest temperature variations
  • conveniently stackable and scalable
  • minimum pressure drop, maximum heat transfer
  • night cooling
  • solar heating
  • heat recovery ventilation systems
HeatStixx®

Realized in partnership with klara energy systems GmbH, HeatStixx® provide the chance to upgrade existing storage systems. The cigar-shaped ellipsoids can easily integrated in every heat or cold storage unit by using standard 1,5 inch joints. Owners of the upgraded systems can benefit from SmartGrid tariffs, or may utilize power-to-heat in order to optimise the power consumption of their solar power installations.

Easy retrofitting:

  • Integration via standard 1,5 inch joint
  • boost feature for all kinds of storage systems
  • heat pump system
  • power-to-heat systems (e.g. solar power generation, SmartGrid tariffs)
