Sustainable and Energy-Efficient Production Cooling
FAHRENHEITS's adsorption cooling systems are robust, low-maintenance, and very reliable. This makes them particularly suitable for often demanding production environments. At the same time, they help you achieve your energy goals: Because they save up to 80% electricity compared to conventional cooling systems. This makes them a smart solution for cooling welding, CNC, molding or other machines, or for creating a more pleasant room climate for your production workforce. An additional advantage: FAHRENHEIT adsorption chillers use pure water as refrigerant. F-gas regulation is thus one less thing for you to worry about.

Recycling Heat to Create Cold

Sources for the drive heat of the adsorption chillers are easy to find in production facilities: For example, air compressors, or thermal manufacturing processes.

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.

ZWL LEIPZIG

COMPRESSED AIR WASTE HEAT: NEW GEAR PLANT LEIPZIG GMBH

2016

The NZWL Group is an international manufacturer of engine and transmission parts (gears, synchronizers, shafts), gearbox assemblies and fully assembled gearboxes for the automotive industry. In order to utilize the thermal energy of its compressors more efficiently, in 2016 it commissioned two eCoo 2.0 I 10 IPS adsorption chiller units.

The cold produced in this way is used to cool tools. The company has a solution that is as economical as it is ecological – especially against the background of multi-shift operation, which requires almost constant demand for compressed air and cooling.

F.U.N.K.E. COMPONENTS GMBH

TURNKEY KWKK SOLUTION IN CONTAINERS: F.U.N.K.E. COMPONENTS GMBH

2015

f.u.n.k.e. Components produces around 75 million plastic articles per year on 25 injection moulding machines. The demand for energy, heat and cold is correspondingly high.

The energy-efficient and sustainable solution: FAHRENHEIT integrated a turnkey energy, heating and cooling module into the existing infrastructure. The cold generated by adsorption is now used all year round for production processes – for example for the cooling of tools. The drive heat for this comes from the CHP of the entire system. This compact CHP solution is housed in a container in a space-saving manner.

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 recovered for hot water systems.

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.

The cold produced in this way is now used for cooling tools. The company has a solution that is as economical as it is ecological – especially against the background of multi-shift operation and thus an almost constant need for compressed air and cooling.
