New Rittal Electronic Motor Controller for RiLine Compact Busbar

A new electronic motor controller is now available for Rittal’s RiLine Compact busbar system.

All it takes is a matter of seconds for the controller to simply clip the controller onto the busbar.  Its easy wiring means installation costs are lower than those for traditional electro-mechanical devices.

The controllers use hybrid electronic technology, enabling both direct and reversing functions in one device. There is integrated motor protection against overload and short circuit, as well as fault alarms.

The electronic controller is only 22.5 mm wide so it offers substantial space savings over standard contactors and overloads. This in turn allows for higher busbar installation density, which can reduce the size of both enclosures and busbar systems.

The devices are available in the following three power classes:

Article number Name
9635.400 Motor controller 0,6A
9635.410 Motor controller 2,4A
9635.420 Motor controller 9A

Award nomination for the new Blue e+ Cooling Unit

The Energy Awards 2018 taking place 5 December at London Hilton, Park Lane will bring together an audience of over 500 industry heavyweights to recognise and celebrate the very best achievements in the industry.

Blue e+

Rittal are excited to announce that we have been nominated as a finalist for the – Energy efficient product of the year HVAC&R award for the Blue e+ 1.6kW Cooling Unit.

Cooling for all Edge Scenarios – From Single Racks to Entire Data Centres

  • A world-first: a hybrid system with 35 kW cooling output
  • Other highlights: refrigerant-based solutions with 20 kW and 35 kW outputs and a new generation of water-based IT cooling systems for environments with high air humidity
  • High degree of redundancy ensures the high uptime required for edge solutions

Rittal has added 20 and 35 kW output classes to its portfolio of refrigerant-based IT cooling solutions, meaning it can now offer a cooling solution from 3 kW right through to 55 kW.

The portfolio also includes a world first: a 35 kW hybrid version that will utilise indirect free cooling where conditions are suitable, making it highly energy-efficient.

Compact cooling systems are also available in high-redundancy configurations. These meet the need of today’s IT infrastructure for high uptime – which is of particular importance for state-of-the-art edge computing solutions to ensure the uninterrupted flow of data.

Hybrid solution with natural cooling when conditions are suitable

The innovative liquid cooling package (LCP) DX/FC Hybrid includes both a refrigerant circuit (DX = direct expansion) and a separate water circuit (CW = cold water). This means that the solution can deliver the required cooling output very efficiently, in line with external temperatures.   

It’s a particularly cost-effective solution for locations with low to moderate ambient temperatures as it automatically switches to indirect free cooling when outside temperatures are low, using its external hybrid condenser with integrated free cooler. This use of indirect free cooling is key to helping lower operating costs.

Efficient, space-saving refrigerant-based solutions

The new LCP DX solutions for suite cooling have outputs of 20 kW and 35 kW and suit small to mid-sized environments. Both devices are inverter-controlled and ideal for cooling IT hardware.  They can precisely control the server inlet air temperature with a maximum deviation of approximately 2 kelvin. The cooling output is continuously adjusted in line with heat loss in the rack, minimising energy consumption for cooling, and cutting IT operating costs.

Space-saving rack cooling with the typical “back-to-front” air routing used in IT can be delivered through the roof-mounted cooling unit, even for smaller output categories (up to 3 kW).

The LCU DX IT cooling unit is compactly designed and offers cooling outputs of 3 and 6.5 kW, with or without redundancy.  In order to save space, the internal unit is installed between the 19-inch rack and the side panel.  This solution, designed for maximum uptime, has two external units but only one internal unit.  Inside is a heat exchanger with two cooling circuits, two power supply units and two separate controllers.  It automatic switches over to its backup mode in the event of faults or when operating-hour thresholds are reached, increasing reliability in IT facilities that need to operate around the clock.

It reports any faults to the Rittal CMC III monitoring solution, and can also maximise energy efficiency by cooling individual racks, rather than the entire environment.

High-performance cooling with water

Rittal’s product suite includes water-based LCP CW rack and bayed suite cooling systems.  Here too, the company is adding new products in the shape of IT cooling units with high cooling outputs – up to 55 Kw – and a small footprint of only 0.36 m², enabling the best possible use of available space.  

Their high water inlet temperatures allow greater use of indirect free cooling, again, reduce operating costs. They can be deployed in conjunction with a heat pump, as their LCP CW glycol coolants can generate high water return temperatures.

Use in environments with high air humidity

The special features of these units include improved condensate management through an innovative spray eliminator employed in some LCP Inline CW models.

As a result, they are ideal for areas with high air humidity or low water inlet temperatures. Furthermore, a new plug-and-play mount means that the fan unit can be replaced without the need for tools.

Rittal’s Edge Computing, Open Compute & Open19 CPD Seminars

Rittal Ltd has developed two new accredited seminars as part of its highly-respected Continuing Professional Development (CPD) series.

Challenging  “The Edge” – IoT

The first seminar Challenging  “The Edge” – IoT looks at the rise of Edge data centres. 

It considers how the growth of cloud storage, alongside the need for higher speed and low latency, has fulled Edge Computing to support new technology such as 5G, as well as the rise in video content, and machine-to-machine learning (IoT). 

In contrast to existing data centres, which are generally sited where energy costs are lower and space is inexpensive, Edge data centres will be smaller and situated nearer users, in a mesh network.

Rittal’s pre-fabricated modular mini data centre is a complete pre-fabricated solution on a mini scale, which can be placed close to data sources.

Rittal CPD Seminars 2018

Open Compute Project & Open19 Project

The second seminar entitled Open Compute Project & Open19 Project explores the Open Compute Project (OCP), which was launched in April 2011 by Facebook in order to share their hard earned know-how to build low-cost, highly efficient data centres particularly those used by hyper-scale cloud platforms.  

The main thrust is to radically alter the way power is distributed to the server by switching to locally derived DC power, lowering power requirements and increasing airflow around the components, thereby reducing cooling costs.  Rittal’s Open Compute Project racks are a standard design, which accommodate different DC supply voltages. 

A core philosophy is that any participants who want to have a server, or other hardware, recognised as OCP-compliant must open source it.

Alongside this is LinkedIn’s Open19 project, aimed at smaller data centre operators who are smaller in size, but which house the majority of the world’s IT infrastructure. Open19 focuses on edge computing alongside the core data centre hardware, and unlike OCP, uses uses a licensing framework that lets companies protect their IP while still being actively involved.

The seminar explores Open19 hardware, which is built around the standard 19“ rack such as Rittal’s TS IT.  IT also explores how Open19 operates with a similar ethos to OCP in that it rearranges server hardware to enhance airflow through the components.
