EU-Projekt N.O.A.H. | New Outstanding Alternative Heat storing material
As a result of the successfully completed ZIM cooperation project "MagnesiaHSM" funded by the Federal Ministry for Economic Affairs and Energy, we are now launching our EU-Projekt 2018.
Prospective cooperation partners only need to fill out a Letter of Intent in which they confirm their interest in EcoMagHSM. If you send us the "Letter of Intent" (available here) by e-mail, we can provide you with the recipe and a free license for the entire duration of the EU project (HORIZON 2020 PH1) immediately after the start of the project - according to the EU directives.
The direct comparison of the length of the cooling/unloading phase of EcoMagHSM and the original memory modules made of fireclay and soapstone, shows an 30% extended unloading phase with identical test parameters. The new ecological storage material has further advantages over chamotte soapstone and other traditionally used materials.
EcoMagHSM is 30-50% more efficient. This means it also saves the same amount of wood, brown coal and the resulting particulate matter and CO2. And it can also be used built-in components in the combustion chamber of stoves for the further reduction of particulate matter. With its excellent heat storage and release properties, EcoMagHSM absorbes and stores about 30-50% more energy and is at the same 30-50% cheaper than all competitive solutions - see Fraunhofer Institute for Building Physics IBP under DOWNLOAD.
An increase in the bulk density / mass of fireclay brought no advantages in all test series, because chamottes are generally too slow in heat absorption and inflexible (flow velocities). The weight advantage (up to 65% depending on the recipe) of EcoMagHSM even against extremely heavy chamottes is considerable, since EcoMagHSM, in contrast to soapstone / chamotte, has an ideal balance between heat capacity and suitable thermal conductivity.
Specific heat capacity as a function of the sample temperature: Results of the mixtures and starting materials investigated and sample of chamotte (HBO +). The results of the measurements also show that fireclay only absorbs heat in appreciable quantities above 100° C. EcoMagHSM stores much more efficiently at temperatures as low as 20 ° C and above 50% :
In addition to the heat capacity, the thermal conductivity plays an important role in the application of EcoMagHSM as a storage material. The higher the thermal conductivity, the faster the heat can be stored and recalled. The thermal conductivities of the EcoMagHSM blends are between the value of the chamotte sample of 0.5 W / (m · K) and the EcoMagHSM peak of 2.1 W / (m · K). Accordingly, a very wide range of thermal conductivity can be set via different formulations. The amount of mixing water alone can be used to set w / c value, compressive strength, bulk density, porosity, thermal conductivity and specific heat capacity.
Increasing the flow rate from 0.5 m / s to 1 m / s has a negative effect on the Chamotte/Fireclay sample HBO + (left diagram). The integrated surface of the heating phase of the EcoMagHSM specimen HSM79A, in relation and under identical conditions, is 53% larger in this experiment. From this, it can be deduced that the EcoMagHSM storage material reacts much more flexibly with respect to the change in the flow velocity, which is to be evaluated as very positive especially when used as a storage brick in the field of wood firing.
EcoMagHSM combines the advantages of the individual state of the art solutions while having none of their drawbacks and EcoMagHSM is about 30% cheaper to produce.
EcoMagHSM has a higher heat capacity with an adequate heat conductivity, thereby allowing an efficient absorption and storage of the heat at a lower price than all other comparable materials (ceramics). It can be made of natural, hazard-free raw materials without a high temperature process. It allows flexible forms and sizes and is usable for a wide range of applications.
Fraunhofer Institute for Building Physics accredited an excellent longterm stability.
Due to the advantages already mentioned, the material enables both use in heat-storing system modules and in the fireplace itself. EcoMagHSM storage bricks can also be used in the firebox/combustion chamber if the temperature range of 600 ° C - 900 ° C is not exceeded in the long term, e.g. as baffle plate with / without cyclones:
The combustion chamber of the new EcoMag combi stove - Demonstrator II - receives preheated combustion air through a slot in the back wall of the stove. The flue gases are deflected by an EcoMagHSM baffle plate, which promotes the combustion process considerably, and then pass the afterheating box before they reach the chimney. The convection air, heated by the burner and the afterheater, is fed through the Hypocausts system from EcoMagHSM storage blocks and heats it up quickly as well:
In addition to the use as a free-formable casting mortar, the production of commercially available bricks has now also been evaluated by the use of EXTRUDERs. For this purpose, an extruder built in 1970 (output according to specification: 100-200kg per hour) was adjusted with the simplest methods. With the very simple and inexpensive test set-up, 60 bricks per hour could already be produced - the rough ProtoDesign is hopefully self-explanatory. With a modern EXTRUDER the production of 600 bricks per hour is possible with an hourly output of approx. 1000-2000kg. © GERMATEC | ROHDE
With simple hydraulic / extrusion presses and extruders it is possible to produce more than 4000 stones per day for significantly less than € 10k investment in the respective machine - and this without burning / sintering as EcoMagHSM hardens in the air ...
At 1.80 kg / liter, the raw density achieved with EXTRUDER meets the target specifications for a significantly more efficient and economically producible EcoMagHSM heat storage brick :

The final optimization of the recipe in terms of w/c value, binder consumption, strength, bulk density, compaction, spread and slump resulted in a mixture that can be processed both industrially and handcrafted / manually. The production of our EcoMagHSM Ready Mixed Mortar will start in 2019 and will be distributed EU-wide under the registered brand name EcoMag®HSM by Lehmann & Voss (LehVoss Group). The Ready-Mixed-Mortar allows to reach a wide range of applications and end users with just one product, as it can be casted or extruded into almost any necessary shape.
With the LuV Group EcoMag has access to the necessary infrastructure to provide large volumes of EcoMagHSM mortar to its commercial customers. The licence model serves commercial customers, who cannot or will not buy the EcoMagHSM Ready Mixed Mortar, because they prefer a licensed recipe to use the raw materials in their production lines (e.g. brick industry).
The licenses are freely negotiable, and ...
In order to minimize the transport distances and freight costs, the material can be processed EU-wide by already established manufacturers under license. The local/decentralized manufacturing without long transport routes gives EcoMagHSM products a consistently positive eco-balance.
Starting in 2019 EcoMag will give free "Early Bird" licenses to SMEs EU-wide. With this license commercial customers get the recipe for EcoMagHSM and can buy the raw materials EU-wide directly at EcoMag's strategic production and distribution partner Lehmann & Voss & Co.KG (LehVoss Group).
This way EcoMagHSM can be produced for a very low price also by small companies (e.g. stove and heating handicraft businesses). When you are interested feel free to contact us...
