The cooling system and operation of chillers
Delivering precision cooling as standard, chillers – also called recoolers or liquid coolers – ensure a constant temperature in the case of high thermal loads. The central inverter precisely controls the electronic expansion valve as well as the speed of the DC motors for the fan and compressor. Thanks to this precision cooling, connected items of equipment such as machine tools also operate with a similarly high level of precision, and work does not become less accurate. Rittal chillers are available in various designs.
Chiller variants from Rittal
TopTherm chillers
Our TopTherm chillers cool the cooling water centrally and cost-effectively, supplying systems such as air/water heat exchangers. TopTherm chillers have a nano-coated condenser as standard. These chillers are available as standalone solutions and as roof-mounted or wall-mounted systems.
Blue e chillers
Blue e chillers cool cooling water centrally and cost-effectively to control the temperature. Microchannel technology reduces the volume of refrigerant required, while safety functions achieve excellent safety. Touch displays and communication interfaces make for extremely user-friendly operation. Blue e chillers are available as floor-standing enclosures.
Blue e+ chillers
Blue e+ chillers, too, supply air/water heat exchangers with cooling water. Their touch displays and smart communication interfaces ensure intuitive operation. That’s not all, though. Thanks to state-of-the-art technology, including speed-controlled components and inverter technology, Blue e+ chillers can deliver energy savings of up to 70 percent. In addition to all this, international approvals and their multi-voltage capability mean these chillers can be used worldwide.
Chiller cooling – areas of application
Chillers with liquid cooling are used in various areas of application, including machine cooling and process cooling. Chillers can be used to cool enclosure systems and machinery. The fact that water has an energy density up to a thousand times higher than air makes it possible to dissipate a high heat loss in a small space. This operating principle makes chillers exceptionally efficient. They maintain a constant temperature level in all kinds of industries, such as mechanical engineering, the plastics and textile industries, the IT sector and other industries, too.
Benefits of chiller-based water cooling
Using a chiller for liquid cooling offers numerous benefits. Also known as a water chiller or refrigeration unit, a chiller is an efficient solution for high thermal loads, such as the ones that occur in industrial production. In addition to needs-based climate control, the benefits you can enjoy with a Rittal chiller include:
- Simple operation, thanks to touch displays and smart communication interfaces
- Integrated safety functions
- Flexibility during assembly and installation, thanks to standalone, wall-mounted and roof-mounted variants, for instance
- A compact and space-saving design
- Suitability for global use, thanks to compliance with international technical standards and compatibility with common mains frequencies and mains voltages
- Sustainable and eco-friendly cooling – especially with the Blue e+ chiller
- Straightforward ordering, thanks to a chiller configurator and order lists
- Rapid availability as a result of standardised series solutions for chillers
- Global availability of spare parts and quick re-ordering
- Easy monitoring of ongoing operations, thanks to remote monitoring
- Enhanced monitoring options using a flow sensor or fill level / filter mat monitoring
Chiller configurator
To make it easier for you to select the right chiller, we have developed a chiller configurator so you can determine exactly what you need. Adapt the cooling output, volumetric flows and refrigerant temperatures to your specific requirements in just four steps:
- Enter your heat loss in the chiller configurator.
- A selection of designs is then suggested based on the heat loss you have indicated.
- Having selected your design, you are next offered appropriate accessories.
- Once the configuration is complete, an order list with the necessary components is generated for you.
The chiller configuration function provides you with an automated, error-free calculation basis and an associated compilation of products and accessories. What’s more, ready-made options and the order list make for a straightforward ordering process. You can transfer the relevant details directly to the Rittal Online Shop to see prices and availability. Production documents such as characteristic curves, drawings and parts lists are also available. Benefit from a wide selection of off-the-shelf chiller outputs ranging from 1 kW to 50 kW.

FAQs about the chiller-based cooling system
A chiller is a cooling system based on liquid cooling. The cooled liquid is fed into an air/water heat exchanger. Solutions such as industrial chillers are ideal for dissipating high thermal loads, such as the ones that occur during industrial production processes. When enclosures have a high packing density and generate a correspondingly large amount of heat, chillers provide an efficient and environmentally friendly way of maintaining a constant temperature level.
Chiller-based cooling uses cold liquid that is routed into a pipework system. The temperature of the cooling water is controlled centrally and cost-effectively and is distributed via the air/water heat exchanger.
A water chiller, also simply called a chiller, is a unit that uses liquid cooling to control the temperature. Water is cooled via a cooling circuit and fed into the system at appropriate locations.
