There were unlimited options for building an innovative new chiller. We simply chose the best.

Developed for use in extreme conditions

With the launch of the MC series RIEDEL is expanding its extensive

range to include a particularly energy-efficient and reliable series for

medical systems. Six models with refrigeration capacities ranging from

30 to 70 kW ensure ideal operating conditions for modern diagnostic

devices and in medical facilities.

During development of this series, the focus was on extremely system

stability operation and effective cooling within narrow tolerance limits.

For this reason, the selected components and the construction principle

were precisely adapted to meet the high requirements of continuous

clinical operation. The refrigeration capacity is reliably generated even

under extreme climatic conditions. The technical concept of the units

meets the high requirements of noise emission control and is both

ecologically and economically ground-breaking.

RIEDEL Competence – Our commitment

RIEDEL's high standards speak for themselves. This is as true of the

design of the new chiller series as it is of the implementation of

customer-orientated adaptations or solutions. This allows even the most

demanding and complex requirements to be fulfilled.

RIEDEL provides invaluable pioneering work in the development of new

technologies, the improvement of energy efficiency and environmental

protection, and the reduction of lifecycle costs.

We have a clear picture of the requirements of your equipment.

Designed for the most modern diagnostic and therapeutic systems

The cutting-edge technological development in imaging diagnostics and radiotherapy requires permanent

higher level of performance from the supporting peripheral equipment. The sensitive technology Magnetic

Resonance Imaging and Computed Tomography or modern Linear Accelerators needs to be reliably and

precisely cooled during operation. This is the only way these medical devices can produce accurate results.

Furthermore, our RIEDEL MC Chillers are also designed to provide cold water for air conditioning.

Maximum possibilities at minimum lifecycle costs

No matter where you are planning to use a MC Chiller, the series will impress you in every climate zone.

The energy-efficient design can be used at outside temperatures ranging from -37 °C to +55 °C. This is

ensured by various factors, including the robust design and the perfectly compatible components sourced

from best of its class suppliers. The series consists of six models with refrigeration capacities up to a

maximum of 70 kW. The units are exceptionally quiet and have impressively low lifecycle costs.

MC Chillers can be enlarged with the energy-saving system module ESS11 in uniform appearance.

Upgrading of already installed units with additional accessory is feasable at any time. Models with 60 Hz-

technology are certified to UL and CSA standards. All models correspond to the RoHS directives and meet

the TR requirements (previously GOST-R).

A chiller for the most extreme climate zones.

For use at ambient temperatures between -37 °C and +55 °C

Cooling concept for all climate zones

The performance capacity of cold water units depends primarily on the refrigeration design and the

refrigerant used. RIEDEL has decided to use the advantages of the high-performance R134a for the MC series –

the unit therefore provides a universal solution.

The conditions and the ambient temperature can only be partially assessed before the implementation of the cold

water system. The prognosis is made more difficult by the very different regional effects of global climate

change. The MC series covers limit temperatures ranging from a polar -37 °C to a tropical +55 °C. These

extreme conditions have been simulated and confirmed in RIEDEL's own climate chambers many times over.

With our ESS11 energy-saving module, you can precede active cooling at appropriately low ambient

temperatures and thus achieve the best possible efficiency for your cooling application while significantly

reducing operating costs.

The sound power levels were determined by the sound pressure levels measured in compliance with DIN EN ISO 3741. The sound pressure level measurements (dB(A)) were carried out on an enveloping surface

that was placed around the sound source (distance: 0.5 m). According to DIN EN ISO 3744, the sound pressure level measurements must be carried out in this way to determine the sound power level.

Low sound emissions

Looking at the sound pressure level, it becomes clear that the precise coordination of all the device components

pays off. The MC Chiller is agreeably quiet even when operating at full load and barely influences the surround-

ing noise levels. If the device is operated at sound-optimised partial load the sound pressure level decreases a

significantly more.

Even when installed outdoors near to therapy areas and hospital ward blocks this “quiet-as-a-whisper”

operation has a positive effect. Convalescence and quality of life will no longer be affected by disturbing

background noise. Complicated and expensive building measures are avoided.

The standard version contains:

Optimised air circuit

Use of EC fans

For further sound optimisation,

the following options can be used:

Sound shell/sound insulation for the compressor

Anti-vibration mats

With a level of 35 dB(A)*, the MC Chiller is "quiet like

a smooth rainfall" at a distance of just 50 m.

* Partial load operation, type MC649-50** Type MC649-50, at a distance of 10 m

Typical noise level comparison:

Sound pressure level at full load: 57.0 dB(A)** andSound pressure level at partial load: 48.5 dB(A)** (cooling capacity 11 kW – noise-optimised)

RIEDEL Controller Board and RIEDEL displays

The RIEDEL Controller Board (RCB) consists of a RIEDEL-specific regulating and control unit and the RD4 and RD3C

operating displays. The separation of the controller and the display unit offers several advantages: The control

panel can be installed taking up a minimum of space, and if required, can also be replaced by other operating

units. The core of this system is the STAR-Module. The RIEDEL RCB contains all important control elements and

has the following features:

The following operating displays are possible:

Standard RD4: Monochrome graphical LCD with real-time clock

and datalogger, incl. USB connection

Remote control RD3C: The display allows for remote control

and and remote diagnosis of networked coolers, equipped with

a 4.3" TFT colour graphics touch screen. The RD3C display can

also be accessed from around the world using a browser or a

smartphone.

Lifecycle Management.

Designed for maximum performance and minimum operating costs

Safety

The performance and reliability of a cold water unit can only be determined viewing all components during

operation. We considered all possible eventualities and stresses when selecting all components. They bear up

to the qualitative as well as the economic demands made of a modern chiller.

Lifecycle Management

RIEDEL Lifecycle Management perfects this approach. Regular maintenance of the system ensures the retention

of the value of your investment and early detection of any potential malfunctions due to remote diagnosis. This

support is guaranteed for the entire usage period of your system.
