UK launch of Rittal’s Innovative Blue e+ Cooling System

A new generation of cooling units is being launched in the UK by Rittal, the leading global enclosure and climate control specialists.

The Blue e+ is a major advance for the sector and represents a quantum leap forward in terms of efficiency and cost effective operation. 

As well as being far more energy efficient than existing cooling solutions, Blue e+ systems use state of the art technologies, packaged in a unique manner, to also deliver greater flexibility, safety and ease of handling.

Key to the efficacy of the Blue e+ is Rittal’s innovative patented hybrid system.  “The hybrid system increases energy efficiency significantly,” says Steffen Wagner, Rittal’s Head of Climate Control Product Management.

“It uses a clever combination of a compressor cooling device and a heat pipe to take maximum advantage of passive cooling. The compressor only kicks in when passive cooling becomes insufficient to meet demand,”he adds.

Blue e+ units are six times more efficient than a conventional cooling unit at a part-load of 15 per cent in heat-pipe mode. At a part-load of 65 per cent, in hybrid mode, with both the compressor cooling device and heat pipe in operation, Blue e+ is four times more efficient than a conventional unit.

The energy efficiency of the compressor cooling is also very high. DC motors power both the fans and the compressor, while inverter technology adjusts the compressor and fan speeds so the cooling output matches demand at any one time.

“Initial tests have shown that thanks to the high energy efficiency of new cooling units, energy savings of up to 75 per cent are possible,” says Mr Wagner.

Multi-voltage input for the grids 
All Blue e+ units have multi-voltage capability and so are suitable for all standard power networks worldwide.  Input voltages range from 110 V (single phase) to 480 V (three-phase) at grid frequencies of 50 or 60 Hz.

Superior process reliability 
Demand based cooling eliminates both thermal stress and any temperature fluctuations within the enclosure. This, in turn, increases the service life of the cooling units and enclosure components and also means higher process reliability.

The Blue e+ range has cooling capacities that extend to up to 6,000 watts (the maximum available from the preceding Blue e unit is 4,000 Watts) and it can be used in ambient temperatures ranging from -30°C to +60°C.

Easy handling for faster service 
Standardised communication interfaces ensure easy integration into a production plant’s control systems.  The 4.3″ TFT touchscreen display presents users with key information at a glance, while system messages are plain text and multi-lingual. Moreover, a variety of protocols permit real time data transfer via the Ethernet interface.

What’s more, all Blue e+ units are identical across all markets which means that spare parts are easier to get hold of.

A World of Knowledge with Rittal CPD Seminars

This November, Rittal will be running its next series of
accredited seminars designed to support industry professionals
in their Continuing Professional Development (CPD).

The success of the company’s CPD programme, which launched
last year, has prompted it to be expanded to cover two new topics
about enclosures. Topics explored within the programme now include:  the relocation
of data centres; their energy efficiency; the application of IEC 61439;
enclosure equipment protection; and energy efficient cooling.

The seminars have all been reviewed and assessed by the Chartered
Institute of Building Engineers (CIBSE), to ensure the technical content
is of a high standard.

Rittal CPD Presentation

All attendees receive a certificate as evidence of their participation.

The seminars are free of charge and include short informative
presentations and a workshop:

New for this year – Energy Efficient Cooling
What it covers:  an overview of the importance of the adequate
provision of appropriate cooling when specifying enclosures.
Thermal performance, more than any other element, will form the
base line for the design of any enclosure. The seminars cover the
need for enclosure cooling; the cost of ignoring overheating;
tell-tale signs that an existing enclosure is too hot; methods to establish
the enclosure internal temperature; cooling solutions for particular
environments; impact of incorrect installation and ser service and
maintenance.
Aimed at:  mechanical engineers, facilities managers, estates
managers, electrical engineers and IT managers.

New for this year – Enclosures Equipment Protection
What it covers: the considerations needed to ensure the correct
and safe specification of industrial enclosures.  Providing the right
environment for the equipment being installed will deliver the best
solution, safety and reliability and the seminar covers an array of
topics including what is an enclosure; equipment protection; IP
and IK ratings and the effects of modification; security; noise levels;
maintenance etc.
Aimed at:  mechanical engineers, facilities managers, estates
managers, electrical engineers and IT managers.

The remainder of the seminars will reflect last year’s successful series
and include:

•    Building a Data Centre in the Perfect Storm
•    An Introduction to the Application of IEC 61439
•    Date Centre Energy Efficiency
