RUBITHERM® is your innovative partner for PCM-Technology and leads the way in developing economic and ecological applications of phase change materials for a wide range of thermal challenges in industry, healthcare and logistics.

RUBITHERM® Technologies GmbH is on of the principal PCM suppliers worldwide and provides solutions for heating and air-conditioning systems, temperature-controlled transport of sensitive goods (CRT, 2 – 8°C, etc) and also therapeutic and medical products.

RUBITHERM® Technologies develops and manufactures phase change materials (PCM) for these and other applications since 2006 when it was founded as the successor company of RUBITHERM® (est.1993).

PCM exploit the phase change from solid to liquid or vice versa for storage and subsequent use of heat or cold at constant working temperatures – like a rechargeable battery, but for thermal energy.

In addition to sales of our proven storage materials and semi-finished goods, our focus is on the development of new and innovative products.

Based on the extensive experience we have accumulated over the last years, RUBITHERM® has developed a very select know-how, i.e. calibration of the working temperature to customer needs, adaptation of the viscosity, non-flammable long-term stable PCMs, coloring, filling of containers, etc, including numerous patents. We have unique competences in PCM-carrier combinations on basis of fibres, granulates and powders. Often it is these bounded forms that make PCM usage feasible in practical systems.

At the moment we are developing a new type of granulate for direct application in water tanks. This will for the first time allow high thermal power output whilst simultaneously reducing the size of the storage tank itself.

 

Projects

Botanical Garden Berlin

tropical green house at night

RUBITHERM® also focuses on the development of compact storage modules and their use for climate control in buildings. One of the flagship projects is the storage tower in the tropical green house in the Botanical Garden Berlin. During the day solar heat from the roof is stored in our CSM panels filled with PCM and released at night into the plant area.

This results in considerable energy, CO² and cost savings.

Products

RT -Organic

RUBITHERM® RT is a pure PCM, this heat storage material utilising the processes
of phase change between solid and liquid (melting and congealing) to store and
release large quantities of thermal energy at nearly constant temperature.
The RUBITHERM® phase change materials (PCM’s) provide a very effective means
for storing heat and cold, even when limited volumes and low differences in
operating temperature are applicable.

rubitherm_organisch

Properties:

  • high thermal energy storage capacity
  • heat storage and release take place at relatively constant temperatures
  • no supercooling effect, chemically inert
  • long life product, with stable performance through the phase change cycles
  • melting temperature range between -4 °C and 100 °C

SP - Inorganic

The creation of the latent heat blended material RUBITHERM® SP has led to a new and innovative class of low flammability PCM. RUBITHERM® SP consists of a unique composition of inorganic components.
RUBITHERM® SP is preferably used as macroencapsulated material. Densities of 1,0 kg/l and more can be achieved. This and all properties mentioned below make RUBITHERM® SP to the preferred PCM used in the construction industry. Both passive and active cooling can easily be realized e.g. in wall elements and air conditioners.

rubitherm_anorganisch

Properties:

  • stable performance throughout the phase change cycles
  • high thermal storage capacity per volume
  • limited supercooling, low flammablity, non toxic
  • different melting temperatures between -21°C and 70°C are avaible

 

PX - Powder

RUBITHERM® PX is a heat storage powder which contains phase change material
(PCM) within a secondary supporting structure, in this case a hydrophilic silica
powder. The result is that the bound PCM is always a solid in its macroscopic
form. Used in thermal energy storage applications, the bound PCM melts and
congeals, thus storing and releasing the latent heat associated with the phase
change process.
Advantageous is that for many applications, large quantities of thermal energy
can be stored and released at a relatively constant temperature, even when
limited volumes and low differences in operating temperature are applicable.

rubitherm_pulver

Properties:

  • high thermal energy storage capacity
  • heat storage and release take place at relatively constant temperatures
  • no supercooling effect, chemically inert, almost no volumen expansion
  • long life product, with stable performance through the phase change cycles
  • melting temperature range between approx. -4°C and 100 °C

 

GR - Granules

RUBITHERM® GR is a heat storage granulate which contains phase change
material (PCM) within a secondary supporting structure, in this case a natural
porous mineral particle. Used in thermal energy storage applications, the bound
PCM melts and congeals, thus storing and releasing the latent heat associated
with the phase change process.
In RUBITHERM® GR our patented mechanism ensures that the PCM, when in the
liquid form, does not leak out of the granulate. The result is that the bound PCM
is always a solid in its macroscopic form. Advantageous is that for many
applications, large quantities of thermal energy can be stored and released at a
relatively constant temperature, even when limited volumes and low differences
in operating temperature are applicable.

rubitherm_granulat

Properties:

  • heat storage and release take place at relatively constant temperatures
  • bound PCM’s exhibit little volume change during phase change
  • operate without fluid materials, easy handling
  • long life product, cycles rugged, easy handling
  • melting temperatures range between –3 °C and 100 °C.
  • various granulate sizes are possible

 

CSM Panel

The CSM modules are Rubitherm’s standard multi-purpose PCM panels. They are made from aluminium with an efficient anti-corrosion coating and can be filled with both our RT and SP materials, providing maximum flexibility to the user, depending on intended use.
