FROM INNOVATION TO REVOLUTION

FAHRENHEIT continues to contribute significantly to revolutionizing the world of cooling technology—with powerful, innovative cooling solutions that reduce energy costs and protect the environment.

Discover the fascinating technologies behind our cooling systems here.

ADSORPTION COOLING: SIMPLY INGENIOUS—INGENIOUSLY SIMPLE

Adsorption is the deposition of gases or liquids on the surface of a solid. This bond is purely physical and can be dissolved again as often as required (desorption).

In the case of FAHRENHEIT’s adsorption cooling technology, the gas is water vapor—and the surface of the solid is coated with zeolite or silica gel. The special feature of these materials: They are very porous and therefore have an extraordinarily large inner surface. They can “adsorb” many water molecules like an extremely effective sponge.

The FAHRENHEIT cooling modules are also evacuated. Water therefore evaporates at much lower temperatures than would be possible under atmospheric pressure conditions. When the water molecules accumulate on the adsorber, they evaporate on the evaporater, causing it to cool down. The cooling medium is then cooled via a heat exchanger.

FAHRENHEIT COOLING TECHNOLOGY: EQUIPPED WITH THE COOLEST IDEAS

As the technology leader in the field of adsorption cooling, FAHRENHEIT has been advancing the state of the art for almost two decades.

This pioneering work has resulted in over 20 patented innovations. They all play a major role in ensuring that the potential of adsorption technology can be exploited efficiently and economically. Here are a few examples:

TURNING HEAT INTO COLD

The adsorption chiller is integrated into its environment via three hydraulic circuits.

  • Hot water,
  • Cold water, and
  • Re-cooling circuit
Cold water circuit Heat is extracted from the object being cooled via the cold water circuit
10-18°C (outlet)
Hot water circuit The thermal energy is supplied via the hot water circuit (drive circuit) and used to power the heat exchange taking place in the modules
55-95°C (inlet)
Adsorption
Chiller
Re-cooling circuit The heat from the other two circuits (heat from the object being cooled and heat for driving the adsorption process) is removed via the re-cooling circuit and dissipated into the environment
25-40°C

THE MOST MODERN CONTROL: FOR OPTIMAL PERFORMANCE IN ALL CONDITIONS

All FAHRENHEIT chillers are equipped with a modern, programmable controller. In general, we use the particularly powerful Siemens Climatix controllers.

These controllers enable optimal energy efficiency, performance, and cost efficiency of our chillers—for example via the built-in eco efficiency mode, or by flexibly adapting to the heat source being used. An additional increase in efficiency is ensured, among other things, by the automatic free cooling mode standard in every FAHRENHEIT chiller. This makes cooling particularly efficient when it is sufficiently cold outside.

Another benefit of our control is its easy integration into building control or monitoring systems.

Last, but not least, our control allows for a particularly easy and user-friendly interface.

The Siemens Climatix C 600 control unit was specially developed for use in cooling and air-conditioning technology. Climatix is not just highly reliable and very flexible, it also provides a broad variety of connectivity options. One of these options is a link to cloud based solutions for using digital services and mobile applications.
