Cool Calculator - Hot Savings Potential

It Cooling With Minimal Power Consumption
Consumption has a considerable share of cooling with conventional technologies. This is exactly where the cooling systems from FAHRENHEIT start. Because computer power is converted into waste heat - and the adsorption technology uses instead of expensive electrical energy exactly this already existing heat energy for cooling Also possible:
the drive through efficient external heat sources, such as a combined heat and power plant (see variants 1 and 2). For operators of data centers and server rooms, this results in considerable savings potential. In parallel with the electricity costs, CO2 emissions are also reduced - and the refrigerant used is nothing but pure, harmless water.

Drive Through Waste Heat Of The Cpus.

It is particularly energy-efficient to use the waste heat from the cores themselves for cooling. This variant is particularly suitable for water-cooled systems.

Drive by external heat.

Low power consumption, positive environmental aspects: In economic and energy policy, the use of cogeneration units is particularly interesting. District heating is also suitable for driving our cooling systems. This variant makes sense from approx. 5 kW cooling demand




The Wilhelm Kächele GmbH manufactures and develops rubber parts and rubber composite parts for a wide variety of industries. The focus is on dynamic properties, chemical and thermal resistance, installation space, the non-detachable connection between rubber and solid components made of metal or various plastics, and the reliability of the products.

In 2016, Wilhelm Kächele commissioned FAHRENHEIT to develop, plan and implement a solution for the sensible use of process waste heat for cooling purposes.

During the production process, flue gas waste heat, which is produced during the production of rubber, is converted by FAHRENHEIT’s adsorption technology into environmentally friendly and CO2-saving refrigeration. The adsorption chiller eCoo 2.0 I 10IPS generates 14 kW of cooling capacity, which is used to cool a control room. T he company therefore has an economical as well as ecological solution – hot exhaust air creates cost-neutral cooling for the electrical rooms.
