heatStixx & heatsel

For effective heat storage

It has never been easier to store ecological heat!

All advantages at a glance

Optimized material properties compared to conventional PCM encapsulations
  • Cycle resistance - high phase change stability
  • Flexible - heatStixx can be adapted to almost any storage tank
  • Climate neutral - for a better environment and future
  • Maintenance free

Designed for optimum phase change

Our heatStixx and heatSel are designed in such a way that, in addition to a large surface area, the PCM layer thicknesses are kept so small that the entire PCM participates in the phase change process and thus efficient heat transfer (fast charging and discharging) is achieved even at very low temperature differences.

The design as a hybrid heat storage enables the greatest possible dynamics due to the water content and is therefore perfectly suited for a large number of applications in refrigeration, air conditioning and heating technology.

Increased storage capacity

3-4 times higher with the same volume, simple retrofitting is also possible.

By using our heatStixx and heatSel you can significantly increase the storage capacity of your storage facilities.

Whether in a cold or heat application, the used temperature
spread is decisive. The lower it is, the larger the increase factor becomes.

Our products are therefore ideally suited for achieving a high storage capacity even at low temperature spreads.

Products heatStixx New2

Reduction of the storage volume

3-4 times with the same capacity, ideal for limited space conditions.
 

The effect described above allows you to reduce the storage size with the same factor while keeping the storage capacity constant.

Especially when space is limited, you can use it optimally by using heatStixx. At the same time, you benefit from the smaller insertion dimensions of the smaller tank.

Products heatStixx New2

Increased service life

You benefit twice over! - Peak shifting and extended runtimes.
 

This not only allows you to reduce the output of your heat generator and significantly reduce your purchase costs, but also significantly increases the operating times and thus the economic efficiency as well as the service life.

Because short running times and high cycle rates reduce the service life and lead to high maintenance costs.

Products heatStixx New2

Reduction of operating costs

Reduce power peaks ( = connected power ) ( Peak-Cutting / Peak-Shifting ), use favourable "night current tariffs" and own production.

The increased storage capacity allows you to benefit in different ways.
Let us take a look at a typical daily load graph of a heat generator:

Products heatStixx New2

This daily load graph shows a typical power requirement over one day.
To cover the highest peaks, you need to install a heat generator that can cover the power peaks.

But at times of lower demand it does not run at full power or starts to clock. The operation can be optimized by using a smaller producer, which increases the full load hours.

However, this is only possible if you can already generate these power peaks at another time.

To do this, you must store the energy so that you can make it available later. This requires a higher storage capacity.

Products heatStixx New2

Simplified process control

by transforming the temperature peaks to phase change temperature and thus constant injection and withdrawal temperature. An integration as a thermal switch.

Products heatStixx New2

Higher efficiency

Increase of the COP (Coefficient of performance) and reduction of heat losses by constant temperature level (operating costs -40 % !), use of smaller cold/heat generators possible.

Increase the efficiency of your heat pump.

Your storage temperature remains constant for a longer period if you use heatStixx. So when you charge your storage tank, the storage tank temperature remains significantly lower after the phase change. This is cash money for your heat pump. Because by each higher °C, which this must provide, more energy is needed and that exponentially! This will result in a higher COP and a higher annual performance factor.

This also improves the use of condensing technology. This benefits from a similar effect. This, too, requires the lowest possible application temperature and is therefore only really profitable.

Increase your efficiency class - ErP-Label !

No matter whether you reduce the memory size or increase the storage capacity, you benefit in every case.

By reducing the memory size, you can significantly reduce the memory losses due to the reduced surface area. For example, your class B memory (ErP label) becomes class A and saves you money every year.

Even if you keep the same storage size, you benefit. The losses remain the same, but by using heatStixx you achieve a significantly higher storage equivalent, i.e. your label improves!
