Rittal Launches New Blue e Chillers in 11 to 25 kW output class

Rittal has significantly improved its range of cooling technology for machines and enclosures with its new Blue e chillers in 11 to 25 kW output class.

Using 40 per cent less refrigerant, the devices will make an important contribution to sustainable environmental protection. Meanwhile users benefit from the chillers’ precise temperature control, simplified operation and installation, as well as new safety functions.


Pre-configured option packages, which are quickly available from stock, can meet almost any need, from precision control systems with higher pressure requirements to robust outdoor applications in cold climates.
The re-cooling of liquids by chillers is one of the basic requirements for smooth operation in many industrial processes. For example, enclosures and machine tools must have strict temperature control for the precise machining of metal.


Sustainable and Environmentally Friendly


The latest generation of chillers need to be easy to operate and install, as well as offer maximum user safety. Customers also need fast order turnaround such that customised solutions must be available off-the-shelf, and there is a increased focus on sustainability and environmental performance.


With the development of its new Blue e chiller range and combined with the existing Blue e+ chillers (1.5 to 6kW), Rittal can offer a mature solution package that meets all these needs.


The adoption of a 100 per cent aluminium heat exchanger with micro-channel technology results in stand-out benefits for the user: it improves exchanger efficiency and it reduces the amount of refrigerant needed by 40 per cent compared to other chillers. In addition, the use of aluminium means that the possibility of galvanic corrosion is completely eradicated.

Regulated Performance


The fan and compressor are regulated via a digital controller which means the temperature of the cooling medium can be precisely regulated. As standard, the hysteresis is ± 2 K; however, a precision control (hot gas bypass) of ± 0.25 K is also possible as an option. This prevents temperature fluctuations that cause inaccuracies on the machined workpiece, and also ensures consistent quality.

Ease of Use


The multi-lingual and industrial-grade touch display, plus the intelligent communication interfaces, make both operation and analysis easy.
The parameterisation of the devices, as well as the read-out of the data and messages are performed quickly and shown in plain text. Error messages are prioritised and displayed in three escalation levels.

Rapid Commissioning


Blue e chillers are wired ready for connection and can be up and running quickly, via plug-and-play. Lifting eyebolts make transport easy, as does the base/plinth, which is suitable for transport by forklift truck. Uniform water connections, an adjustable overflow valve (bypass valve) and ideal accessibility to all the components make it easier for fitters and service staff to work on the units.

Designed with Safety in Mind


Integrated overflow valves ensure a constant circulation of cooling water when the consumer is closed, and the pump is running. This protects the coolant pump from overload.
The valve is pre-set for the pump being used 50Hz operation but it can be set for 60Hz. A filling level monitoring system ensures maximum reliability and improved availability. Besides this, optional flow monitors emit an alarm if the flow rate is too low and can detect hydraulic errors such as blockages in the system at an early stage.

Option Packages


Rittal also offers pre-configured option packages that are available quickly from stock and which offer a suitable solution for almost any demand.
For example, performance-enhanced pumps (4 and 6 bar) are available for increased performance. If necessary, a precision control system (hot gas bypass) can be used to improve control accuracy. In addition, the Blue e chillers can be prepared for cold zones of down to minus 20°C, as well as for laser applications, and they can also be fitted with a water-cooled condenser or with pre-heating and customised with special paint.

Greater Systems Security for Solar Energy

Rittal’s infrastructure solutions are playing a vital part in the development of renewable energy as solar energy generation expands into more extreme environments.

Decentralised energy generation, where power is generated both at home and in local communities, is growing in size and importance across the globe as fossil fuel resources dwindle.

Reliable infrastructure such as enclosures, power distribution and climate control systems help support the security of the energy generated by solar technology.

But as the focus for solar generation shifts to Asia and North and South America, there is a growing requirement for robust enclosure systems and reliable cooling techniques that can also be installed outdoors in marine environments (contamination from salt), in the desert (sand/dust) or in harsh industrial settings (smog) are needed to ensure safe operation.

At the recent Intersolar Europe 2015, Rittal showcased innovations from inverters, low-voltage switchgear to energy storage systems.

Among the key products in the range on display were Rittal’s TS 8 double-walled outdoor enclosures with liquid-based, high-performance cooling for central inverters, the new, energy-efficient Blue e+ series of cooling units for enclosure climate control, and DC busbars systems which are increasingly being deployed in converter buses, DC power backup and photovoltaics systems, as well as in energy storage technology.

Furthermore, the company’s “YourHome4Energy” is a modular system designed to meet all the infrastructure requirements of energy storage.

All this technological know-how is backed up by Rittal’s technical teams who can provide expert advice on design and planning systems infrastructure for extreme environments.

Rittal’s TS 8 Enclosure System

In 1999, accompanied by the slogan “infinite possibilities”, Rittal launched its TS 8 enclosure system. Today, with over ten million enclosures manufactured so far, the TS 8 bayed enclosure has become established as the standard for many industries worldwide. 
Key success factors of Rittal’s TS 8 include its high level of flexibility and efficiency, high quality and safety standards, as well as its availability worldwide. The TS 8 enclosure is used in 92 percent of the world’s 1,005 branches of industry and has thus conquered nearly every industrial market within 15 years.

Industries include mechanical engineering, panel building and switchgear production, the automotive industry, energy, as well as information technology and telecommunications. The food and processing industries are also increasingly the stage for a robust and successful enclosure system. 
As a platform for the “Rittal – The System.” modular system, custom-fit solutions can be created for power distribution, industrial automation, facility management, and data centres, thanks to the optimum technical interaction of components from mechanics, climate control and power. Faced by a variety of applications, customers no longer have to rely on different enclosure types, but can always benefit from the advantages of a uniform and universal system platform and a single range of accessories.

Rittal EC fan-and-filter units with speed control

Rittal fan-and-filter units with EC (electronically commutated) motors should be the preferred choice for energy efficiency in enclosure climate control, as their operating ratio is significantly higher than standard AC fan-and-filter units.

Using fan-and-filter units always makes sense if the difference between the outdoor temperature and the internal enclosure temperature is large enough to dissipate the thermal output of the installed components. However, the fans mostly operate without regulation. In other words, they run constantly and always at full speed. In this situation, the savings potential offered by seasonal temperature fluctuations or temperature reductions in the building (e.g. on night shifts or through reduced waste heat in the enclosure) remains unused.

Further optimisation potential exists with an advanced solution using Rittal fan-and-filter units with temperature-dependent speed control. With a new sensor for controlling the speed of the Rittal EC fan-and-filter units, inherently up to 30% more efficient than comparable AC fan-and-filter units, power consumption can be drastically reduced yet again. The sensor measures the temperature within the enclosure and controls the fan speed as needed, right up to independent shutdown at below 20°C.

Replacing AC systems without speed control by EC systems with system control saves money, as shown in the following example: At a manufacturing plant with 50 fan-and-filter units (700 m³/h), run at full load for two shifts per day and five days a week, needing only 20% of the fan speed at night and weekends with reduced enclosure temperatures (20°C), EC technology and intelligent controls, can more than halve the energy costs.

Rittal’s Ri4Power provides the solution for Biomass generation plant room

The development of a power station plant room not only provided logistical and technical issues but also harsh environmental considerations for Nova Controls during their installation of water treatment PLC for a Yorkshire biomass site. The performance of Rittal’s Ri4power modular switch gear busbar system helped to deliver the solution that the site demands.

Location of the existing site structure meant that the panel had to be craned in position, therefore rigidity and strength of the framework was a priority. Ri4Power’s welded frame and tested lifting procedures assisted with the installation of the panel within the new power station plant room.

Safety was a key concern to the end customer therefore Rittal’s internal RiLine60 busbar system was shielded and the panel designed in line with IEC61641 Internal Arc Protection. Form 4 type 6 compartments segregated the control devices, busbar and outgoing terminals, which assisted the cabling on site and offered a higher level of safety.

The panel was located in a plant room where there is a possibility of high levels of moisture and the potential for an acidic atmosphere. To reduce any corrosion or damage to the panel a tropicalized paint finish was used.

Being of a modular design Rittal’s Ri4Power allowed Nova Controls to make last minute changes to the design layout.

In addition to Ri4Power system, Nova also utilised Rittal’s RPE Engineering software to generate design verification documentation that included heat calculations in line with the latest IEC61439 switchgear and Controlgear standards.

Peter Hubbert from Nova Controls commented “Working with Rittal Ri4Power gave us a proven high quality engineered product, incorporating all the solutions required to meet the demanding Form 4 specifications of our client and  the power generation market. This highly flexible product allowed us to design and configure individual compartments with a range of versatile multifunction components, affording us a speedy assembly and a vital cost effective solution in this competitive arena.”

Exposure to high temperatures

Now may be the time to investigate available solutions to the problem of overheating panels. Rittal have a large range of cooling products that will address the problem.
Rittal’s TopTherm fan-and-filter units are an energy efficient means of cooling enclosures but require a clean and cool environment to operate effectively. Air-to-air heat exchangers have separate internal and external air paths, preventing dirt and dust from entering the panel, but still require a cool ambient air to deliver the required cooling.
Cooling units also have separate air circuits but are capable of cooling the air inside an enclosure to a temperature lower than that of the ambient as well as maintaining a clean internal environment. In the case of thermoelectric coolers, the Peltier effect is used to deliver modest amounts of cooling, typically to small panels, offering a lightweight and compact solution. Units from the Rittal TopTherm Blue e range incorporate a refriger-ant circuit and so have larger nominal cooling capacities, up to 4 kW.
Air-to-water heat exchangers can maintain the air inside a panel at a temperature lower than that of the surrounding air and have an additional benefit of allowing heat to be dissipated remotely. Water is the cooling medium used to transport thermal energy to an alternative location, where it may be discharged without increasing the temperature in an already warm environment. To complete the chilled water system a Rittal chiller can be used to return the water to its’ original condition before recirculating to the heat exchanger.

Safe and simple locks

Rittal’s new TS 8 isolator door cover, when deployed in tandem with the actuation mechanisms, adjacent door locking and interconnecting rods, fulfils all requirements of the UL 508 A standard. (A requirement for the North American market.)

Featuring a raft of technical updates and design features, Rittal’s TS 8 isolator door cover range, prevents operators from opening the enclosure and touching live electrical components. The isolator door cover is mounted on the side of the enclosure to which an actuator lever or isolator switch, as the master switch, can be integrated. As a result, the door can only be opened when the isolator switch has been activated and the electricity supply to all components in the enclosure has been disconnected.

A complete row of bayed enclosures can be made safe using a single isolator door cover. The door of the neighbouring enclosure is then operated via the adjacent door latch.
Easy to assemble, the 125-mm-wide isolator door cover can be mounted on either the left or right of the enclosure by a single person. The revised locking mechanism consists of a small number of compact parts, is easy to assemble and can be deployed for all approved actuator levers. Standard side panels can be fitted on the side opening of the isolator door cover with automatic potential equalisation.

Efficient cooling from Rittal

Germany manufacturer SHW Werkzeugmaschinen GmbH, from the Swabian, manufacture moving column machine tools. Machinery from the company includes a 200-ton moving column milling machine, the PowerForce 8, which is used to mill wind turbine stators with an internal diameter of 6.5 m. At the heart of the mill is a new, variable, universal milling head of orthogonal design with a drive power of 90 kW and a torque of up to 1,725 Nm.

SHW relies on the new “Blue e” generation of cooling devices from Rittal to exploit every possible efficiency potential in enclosure climate control. Consuming 45 per cent less energy than the previous generation, the four wall-mounted devices installed on the machine provide cooling of the input and feedback modules for the axle drive, mains filters, chokes, disconnectors, contactors, relays and have a cooling output amounting to 16 kW. The refrigeration factor of 2.47 (the COP, coefficient of performance) results from the ideal interaction of all the components responsible for the cooling output, as well as from the design of the condensers, evaporators, cooling fins, pipe bends and all the other refrigeration components. Using Rittal cooling technology, SHW have been able to connect the devices via a master-slave arrangement.

Another key factor in the increased efficiency is the ideally designed control electronics, which benefit from the new Eco-Mode control system. If continuous operation of the internal fan is not required, shut down is automatic, thus cutting energy costs.

Previously SHW had problems with cooling devices from another manufacturer that malfunctioned under extreme conditions, due to the influence of carbon dust. Since changing to ex-proof cooling units from Rittal, they have been running without problems.
