Rittal - W
orld's most energy-efficient compact cooling unit
In 2016, Rittal introduced the most energy-efficient cooling unit for control cabinets ever: the RittalBlue e+. Now Rittal introduces you to the newest member of the family: the compact Blue e+ S cooling unit with a smaller capacity.
Compact variant
Blue e+ S cooling units are available in three power classes: 300, 500 and 1000 W. A 750 W variant will follow later. Previously, there were cooling units of this size in our range, but they cooled in a traditional way. With the Blue e+ S, we have developed a series that is much more energy-efficient, thanks to speed-controlled cooling and heat pipe technology.
75% energy savings
Chillers with proven Blue e+ technology are the world's most energy-efficient cooling units. This is due to the speed-controlled compressor and fans as well as patented heat pipe technology: a passive way to dissipate heat without additional energy consumption. On average, the Blue e+ S cooling units thus achieve energy savings of 75%. Not insignificant at a time when energy prices continue to rise and CO2 reduction is socially desirable. The investment in the Blue e+ S therefore pays for itself quickly.

Plug & Play
A second difference from traditional cooling units is the fact that the Blue e+ S cooling units are multi-applicable thanks to the unique multi-voltage support. The cooling unit itself recognises the voltage and converts it to the voltage it needs internally. This is a big difference from the traditional variant where you have to choose between a 115 or 230 Volt version. With the Blue e+ S, we bring those options down to one. In addition, the Blue e+ S cooling units have the option of connecting an I.o.T. module. This allows you to create a network of several cooling units and then monitor them remotely. The cabinet temperature, cooling capacity, energy consumption and any warnings can thus be viewed at any time.
Brand new design
Blue e+ S cooling units have a very modern appearance thanks to the vertical louvers (slats). For operation of the system, there is a 'home button' and two 'up & down' buttons. The full-colour touch display of 'big brother' Blue e+ has deliberately not been implemented from a functional point of view. Adjusting settings is also possible via the handy Rittal Scan & Service app available for the Blue e+ S cooling units for both Android and Apple.

Rittal - HUMMEL Cable glandsRead moreIf you want to protect your components properly against external influences, a strong enclosure alone is not enough. There are always cables running to and from your equipment, which is why you need a cable gland in addition to the enclosure for a complete solution for protecting your equipment. This ensures that the end of the cable running to your enclosure is securely attached. After all, your installation is only as good as its weakest link.

Sekisui AlveoRead moreFoam producer Sekisui Alveo has a large factory in Roermond. To support production and maintenance, warehouses and distribution points with thousands of different items are spread across the various halls. Think spare parts, personal protection equipment and consumables. The company cooperates intensively with itsme for management, such as recently with the step-by-step introduction of vendor managed inventory (VMI) for the grab stock of mechanical items.

IECRead moreTo control the expansion of a silo park, engineering & construction company IEC called on Breemes. Being involved in the engineering from the beginning, the electrical service provider was able to make smart proposals for both the low-voltage part and the PLC control. ‘We have always been able to find each other well and when changes occurred, we were quickly on the same page with Breemes.’

Heliox - Charged for DeliveryRead moreHeliox, a developer and manufacturer of charging systems for electric buses and trucks, was already working with itsme when production still took place in the Netherlands. Today, production has shifted to Slovakia, Portugal, and Moldova, and is also happening in the US. itsme remains the “irreplaceable” partner for the supply of electrical components and cable harnesses.
-
BLOK System SupplyRead moreBlok System Supply and itsme have maintained an intensive relationship for many years. Early last year, this was further deepened with electronic data exchange via the Smart Connected Supplier Network. ‘It saves an enormous amount of time and reduces errors. We always have real-time information automatically.’ However, time for personal contact is not saved. ‘That is precisely what makes itsme a very nice party to work with.’
