Dual-Kherr®
The core of Climastar technology, designed to improve efficiency and reduce energy use.
Dual-Kherr® is the patented material used in the front panels of most Climastar products.
It is made from silicon and aluminium. Silicon provides outstanding heat storage capacity, while aluminium is one of the most effective heat-conducting elements.
With Dual-Kherr®, heat is transferred evenly into the room and retained for longer, reducing temperature differences between the upper and lower areas of the space and helping lower energy consumption.
The front part of the panel increases heat transfer for longer thanks to its heat storage capacity and thermal inertia.
The rear part of the panel features a radiant silicon arch structure that improves performance, increases the efficient accumulation surface and optimises warm-air distribution.
The front panel temperature is homogeneous, providing continuous and even radiant heat transfer into the room.
Other types of heaters do not provide such a homogeneous surface temperature.
Only a highly dense, thermostable material can accumulate heat and remain stable indefinitely.
During production, the raw materials are refined into microparticles, placed into moulds and pressed under 2,000 tonnes of pressure.
They are then exposed to 1,200°C for several hours, reaching a semi-liquid state. This creates a stable, homogeneous material with maximum density.
No resins or binders are used — only pressure and heat. This makes the material highly resistant and long-lasting.
This is why we offer a lifetime warranty.
Dual-Kherr® means energy savings
Dual-Kherr® allows room temperature to rise faster.
Room temperature increase comparison
Dual-Kherr® provides a slower drop in room temperature.
Room temperature decrease comparison
Dual-Kherr® does not reduce air humidity.
Convection current temperature variation
Under normal operating conditions, once the set temperature is reached, the convection current temperature drops and does not dehumidify the room air.
Dual-Kherr® reduces convection and increases radiation for greater thermal comfort.
Convection current speed variation
The convection current quickly reaches the set temperature and then drops sharply, stabilising close to zero.
Dual-Kherr® technology allows our products to raise room temperature faster and maintain heat for much longer than other types of heaters.
Under the same room size, room type and heater power conditions, this is how the main heating technologies behave:
Standard convection radiator
A standard convection heater warms the room quickly, but the temperature also drops quickly once it is switched off.
Fluid radiator
A fluid radiator keeps heat in the room for longer, but it also takes longer to heat the space.
Climastar radiator
Climastar inertia products heat the room quickly and maintain the temperature for much longer thanks to Dual-Kherr® technology.
Dual-Kherr® heat accumulation technology minimises temperature stratification.
By avoiding overheating in the upper part of the room, it helps reduce energy consumption and improves comfort.
Standard radiator
In rooms where heat is mainly transferred by radiation, more time or higher power is required to reach comfort.
Convector
With convection heating, the temperature difference between the upper and lower parts of the room increases energy use.
Dual-Kherr®
With Dual-Kherr®, heat is transferred through both convection and radiation at the same time.
