Unused Waste Will Make Powerful Cooling

Protecting Budgets - Protecting The Environment.
Industry and trade need artificially generated refrigeration – and this demand is growing steadily. At the same time, electricity prices continue to rise. The increasingly stringent climate protection goals – and the associated regulations – also call for plant technology to be made energy-efficient and environmentally friendly Many companies face challenges that can hardly be overcome with conventional solutions.
Adsorption refrigeration opens up new, very economic perspectives. Because it uses previously unused waste heat for the intelligent cooling of processes and buildings. The result: significantly lower electricity costs – and a valuable contribution to climate protection. Because the FAHRENHEIT systems not only cool very economically, they also reduce CO2 emissions and work exclusively with environmentally friendly materials.

Economical and Energy-wise Sense

Thanks to their scalability, the FAHRENHEIT adsorption chiller units can be adapted to the cooling requirements up to a rated output of several 100 kW. Compared to compression chillers, they impress with their low maintenance and significantly longer service life.

In addition, our systems pay for themselves very quickly. From this point in time, companies are earning cash through long-term electricity cost savings.

Alupress

Process cooling with compressor waste heat: Alupress manufacturing of aluminium die-cast components

2018

Alupress GmbH is a leading manufacturer of innovative aluminium die-cast components and systems. The company has become a key supplier for the automotive industry through continuous further development in the areas of technology and quality. Here, the environment and the economical use of resources is always viewed as a main concern.

For this reason, in 2018 Alupress chose to use the energy-saving adsorption technology from FAHRENHEIT on their site.
In collaboration with the innovative system engineers GALEK And KOWALD from Mühlhausen (Thuringia), a highly-efficient eCoo 20 X adsorption cooling system was installed. The adsorption chiller unit in this system is powered by the heat from the air compressors. A large part of the cooling capacity, approx. 41 kW, is used all year round to predry the compressed air immediately after it has left the air compressor. As such, the eCoo 20 X saves over 60 MWhe per year and pays for itself in less than 3 years.

ERKO CNC

PROCESS COOLING WITH COMPRESSOR HEAT: ERKO PRECISION AND CONTROL TECHNOLOGY

2016

More than three-quarters of the heat produced by compressed air generators can be used for hot water systems be recovered. But this hot water is useful only in the cold months.

The ERKO Präzisions- und Steuerungstechnik GmbH (also “ERKO CNC”) is u.a. specializing in the production of high-precision components in CNC milling and turning technology. In order to use the thermal energy of its compressors more efficiently, in 2016 it commissioned five adsorption chiller units.

Die so erzeugte Kälte wird nun zur Kühlung von Werkzeugen eingesetzt. Das Unternehmen verfügt damit über eine ebenso ökonomische wie ökologische Lösung – besonders vor dem Hintergrund des Mehrschichtbetriebs und damit eines nahezu konstanten Bedarfs an Druckluft und Kühlung.

FLORIDA EIS

FOOD COOLING WITH SOLAR HEAT: FLORIDA-EIS MANUFAKTUR GMBH

2013

"We make ice cream out of the sun." The Florida Ice Cream Manufactory had set itself an ambitious goal: it wanted to become the first CO2-neutral ice cream factory in Germany. The special challenge: ice cream production requires a lot of heat for pasteurizing the basic mass as well as a lot of cold for cooling.

The solution resulted from the intelligent combination of a solar thermal system with the FAHRENHEIT cooling systems. Of great advantage here is that the Adsorptionstechnik copes well with the relatively low temperatures from the solar thermal. In 2013, the climate-neutral new location in Berlin-Spandau was inaugurated. Since then, it has been regarded as a flagship project in the area of ​​environmentally friendly and energy-efficient food production

GUMMIWERK KRAIBURG

PROCESS COOLING WITH COMPRESSOR HEATING: GUMMIWERK KRAIBURG

2016

The specialist for rubber floor coverings is a leading manufacturer, which relies on sustainable raw materials and environmentally friendly production: high-quality raw materials, especially old car tires, are optimally recycled through ingenious manufacturing processes.

There is hardly any waste in the production of KRAIBURG rubber flooring. Das Verfahren erlaubt es, Verschnitt von maßgeschneiderten Produkten wieder in den Wertstoffkreislauf aufzunehmen. Another important contribution was made in 2016, together with FAHRENHEIT, namely the saving of electricity and the reduction of CO2 emissions.

The task of the FAHRENHEIT adsorption refrigeration plant is to cool a switching and server room with 72 kW waste heat from the condensate of a steam process as efficiently as possible. A highly efficient eCoo 2.0 | 30 IPS adsorption system has been implemented, which constantly reduces the temperature in the control room with 37 kW cooling capacity to 18 ° C.Thus, the switching and server room can be cooled by adsorption cooling for a large part of the runtime almost cost-neutral.

HERDING GMBH FILTER TECHNOLOGY

OFFICE COOLING USING FLUE GAS WASTE HEAT: HERDING GMBH FILTER TECHNOLOGY

2016

Herding® Filter technology – Pure productivity…

…not only does this mean clean, pure air, but also a more economic and environmentally-friendly use of resources. Herding GmbH Filter technology is amongst the leading manufacturers of filter media, de-dusting systems and filter systems for the industry.

Herding reduces environmental pollution during the production process and product life-cycle by minimising the use of non-renewable energies and manufacturing long-lasting products. Herding® products help to conserve the environment, protect the air, people and the environment from harmful emissions and make a significant contribution to the safeguarding of the future. The company sees it as their obligation to also put environmental protection at the top of the agenda on their own premises.

For this reason, any exhaust gases produced by the in-house filter systems are used for the CO2-neutral cooling of the server rooms and office spaces. The three photovoltaics, with an overall output of 100 kWp, also significantly contribute to the protection of the environment. Since their installation over 10 years ago, they have generated valuable solar energy and as a result save around 52.4 tons of CO2 per year. In addition, the company has installed 4 charging stations for electrical vehicles that Herding employees and customers can use for free.

During the summer months, Herding employees can enjoy the environmentally-friendly air-conditioning, made possible by an adsorption system from FAHRENHEIT, which can actually be easily used over the existing underfloor heating.

Simply clever.

KÄCHELE VIBRASTOP

FLUE GAS WASTE HEAT FOR IT COOLING: WILHELM KÄCHELE GMBH

2016

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.
