About the company

The history of “Axiotherm”

The concept of using PCMs (phase change materials) to store thermal energy has existed for many years. To date, however, the right application planning, reliable data on the PCM and in particular complete systems with consistent reliability, pricing, capacity and performance were lacking. There was simply no complete product capable of serial production, something which has prevented success in market penetration until now. The lack of macroencapsulation that was both functional and cost effective to manufacture also played a key role. To solve this dilemma, Axiotherm GmbH was founded by the following entrepreneurs in April 2015:

  • Dirk Büttner - 15 years of experience in PCMs, development and application engineering
  • Andreas Laube - 20 years of experience in PCMs, laboratory testing and application engineering
  • Egon Schmitz - 35 years of experience in plastics processing and encapsulation
  • Hanspeter Logo - 35 years of experience in plastics processing and sales

Collectively, this team has over 105 years of experience in PCMs and encapsulation.

The new products are successfully developed, tested, manufactured and launched onto the market from its two sites in Fürstenwalde, Brandenburg, and Eisenberg, Thuringia. The company's unique selling proposition is its capacity to offer the full spectrum of services from beginning to end, encompassing consulting, project design, product development, production start and the final product. Using intelligent standardised solutions such as air and water applications, our considerable expertise enables the deployment of turnkey products. Successfully completed projects are already being launched onto the market or are on the verge of doing so.
Although the business is technically a start-up, it really started more than a quarter of a century ago!
Our new macroencapsulated PCM products will be a key contribution to the energy reform with their ability to store heat and cold. In other words:

“Getting the right amount of energy to the right place at the right time.”

Spectrum of applications

“Axiotherm” addresses the use of phase change materials in all fields of engineering. The storage of “cold” or “heat” in corresponding media is just one of these fields. Technical heat management is another overarching field in which the function of PCMs contributes to the stability and extended life of systems under thermal stress. It is used for saving energy, increasing comfort, elevating thermal masses, peak cutting (interception of temperature spikes) and more. In each such application, the PCM is a key factor in sustainably improving the system. Our team can apply its many years of combined experience to the benefit of your project, and we are always open to new application ideas. Get in touch with us!


We have already begun a number of executive projects with our “young” enterprise. These will be listed here soon, and we will be adhering to our agreements with our project partners to only publish these projects once they are complete, in part to protect innovations. We thank you for your understanding in this matter.

PCM shortcut

Why PCMs? PCMs (= phase change material) are used to store and dispense thermal energy. Their phase changes play a key role here. Depending on the PCM material (paraffins, salt hydrates, etc.), the intermolecular forces are energetically “broken apart” when a certain temperature is reached (the phase change temperature, which is dependent on the PCM). This is the melting process, which occurs at a constant temperature. A recooling of the PCM, allowing the stored energy to be extracted at a constant temperature resolidifies the PCM. The difference that this energy makes is shown by examining ice – to liquefy 1 kg of water from a solid mass at 0° to liquid at 0°, the same amount of energy is required that would be needed to heat 1 kg of water from 0 °C (liquid) to 80 °C. This is the 'latent effect'.
