RIEDEL also offers new developments for OEM units. Whether you
need space-saving ideas or specific technical parameters – our
engineers work together with customers to develop a customised
cooling solution capable of cooling the machine at the relevant
points and ensuring maximum performance.

RIEDEL applies its entire wealth of development expertise to tackling

extreme and challenging operating conditions. All chillers adapted
to specific customer requirements undergo thorough testing in our
on-site laboratories and environmental chambers. Our test conditions
can simulate extreme ambient temperatures and various levels of
high air humidity – precisely tuned to reflect the exact environmental
conditions the equipment will face in its subsequent operation. As
life cycle costs (LCC) are a key consideration in modern production
businesses, we seek to achieve optimum energy efficiency in all of
our developments.

 Mechanical engineering and coating machinery
RIEDEL offers standard and machinery-specific chillers and system
solutions for a whole variety of cooling requirements within mechanical
engineering. RIEDEL chillers demonstrate their performance capabilities
day after day in even the toughest of environments, e.g. in South-
East Asia, offering outstanding performance around the clock without
compromise. We have chillers suited to a range of voltages and
frequencies for use around the globe.

RIEDEL chillers can be used for a whole host of processing procedures.
The non-conductor can be effectively cooled during electrical erosion,
and coolant can be used to prevent the workpiece from overheating
during grinding. Cooling for lapping and polishing machines has specific
technical requirements, as the lapping granules / polish residue must be
separated by upstream filters prior to cooling.

Coating machines:
Electro-coating machinery requires cooling in order to maintain the
temperature of the dip by means of a heat exchanger. Plasma coatings
with extreme heating of the burner pose a greater challenge. Cooling is
achieved by means of high water pressure and efficient cooling capacity.

 Plastics industry
Tools and hydraulic oils in particular need to be cooled as a result of
the heat from the liquid plastic and the lubricant pump. Maximising tool
life and reducing production waste and operating costs help ensure the
production is economically efficient.

RIEDEL chillers set themselves apart by their high level of reliability and
precision cooling for all relevant functions.

 Everything under control
RIEDEL trusts in its own controller series for the reliable and safe
regulation of its chillers. The controllers register all the relevant
parameters and regulate cooling devices within preset limit values.
The electronics continuously record operating points, which can then
be evaluated using the Studio-ST software included in the scope of
supply. Error messages and operating statuses can be sent immediately
to smartphones or PCs which are connected via either Ethernet or
Internet.

You are always up to date and aware of what is going on with your
cooling system. If there is a fault, you can react to it immediately.

 Your opportunity within international competition
Lower your company's overall energy costs through a flexible response
to ensure optimum energy usage by your applications.

ESS energy-saving system

Developed by RIEDEL, the energy-saving system (ESS) uses an additional
heat exchanger for flexible adjustment to the ambient temperature.
Multimode allows operation to switch between passive chilling (free
cooling), active chilling and mixed operation. Depending on the ambient
temperature and flow temperature, energy costs for cooling are reduced
by more than 50 %.

Heat recovery
Heat recovery is the use of heat energy from the refrigeration circuit as
a source of heat. This method reduces the heat energy requirements for
your processes or building accordingly.
Please note that efficient use of these systems requires heat system
planning that factors in noise protection, system location and additional
space requirements. Increased assembly and commissioning costs are
also involved. Depending on the application, the additional costs can
however often be amortised in less than two years. The RIEDEL
specialists will offer you comprehensive advice on optimising your
chiller.

Heating integration
Heat energy from water-cooled units is transferred via a transfer station
to your heating system. This means you need less or even no conventional
heating energy during the cold months (oil, gas). Heat is also extracted
from your building in the summer months by means of a heat exchanger.
It's easy to convert existing chillers and integrate them into this system.
