Rittal Expands Blue e+ Cooling Range to Meet Market Demand

Rittal

January 24, 2018

Rittal is now expanding its range of cooling units with the addition of a device with an output class of 1.6 kW. Besides being 75 percent more energy-efficient than previous cooling solutions on average, the units also excel in terms of connectivity, safety and handling. The new FTTA approval also makes the UL certification process much easier.

To date, the Blue e+ cooling unit series from Rittal has offered an output range of 2 to 6 kW. But from the first quarter of 2018, the company will launch compact units in a lower output class – at 1.6 kW. “This development marks a new breakthrough for our Blue e+ cooling unit range, to meet market requirements for enhanced and more efficient compact cooling units for enclosure climate control,” says Tim Rourke, President, Rittal Systems Ltd.

In addition to the CULUS listing, Rittal cooling units and fan-and-filter units also have a UL listing in the new “FTTA” (Environmental-rated Accessories for Enclosures) category. With FTTA approval, the type rating/IP protection class of the climate-controlled enclosure is certified by UL.

With its Blue e+ cooling unit range, Rittal relies on an innovative, patented hybrid technology. This combines a compressor cooling unit and heat pipe, which provides passive cooling. The control strategy for hybrid operation is a factor that has significant influence on the huge efficiency gains. Moreover, the compression cooling system of the new Blue e+ is range highly energy efficient. Frequency converters precisely adjust the speed of the DC motors for the fans and compressors to achieve the exact cooling output required. They vary the speed of the system’s fans and compressors by voltage control, so allowing the cooling output to be tailored precisely to the requirements at all times. This cuts energy consumption significantly over conventional solutions. “It has been proven that our cooling units make energy savings up to 75% possible, making them the most sustainable and innovative cooling units in the market,” added Tim Rourke.

All these units in the new range can be operated flexibly in all standard grids worldwide thanks to their multi-voltage capability. Permissible input voltage ranges from 110 V (single-phase) to 480 V (three-phase) in conjunction with a mains frequency of 50 Hz or 60 Hz.

Precise, variable-output cooling minimises thermal stress on components. Constant temperature fluctuations, such as in the conventional two-point control systems are now a thing of the past. This not only increases the service life of the cooling units and enclosure components, it also means higher process reliability.

The new graphical touchscreen control panel displays all key information at a glance. System messages appear as plain text and are multi-lingual. Standardised communication interfaces ensure easy integration in a production plant’s control systems. With the new IoT interface, Rittal also enables Blue e+ units to link to customer-owned monitoring, energy management and/or superordinate systems via OPC-UA, Profinet, SNMP, Modbus TCP and CANopen, enabling predictive maintenance, data analytics and more.

ADVANCED Motion Controls Takes Servo Drives to New Heights (and Depths) with FlexPro Extended Environment Product Line

Advanced Motion Controls is proud to announce the addition of six new CANopen servo drives with Extended Environment capabilities to their FlexPro line. These new drives join AMC’s existing EtherCAT Extended Environment FlexPro drives, making the FlexPro line the go-to solution for motion control applications in harsh environments.

Many motion control applications take place in conditions that are less than ideal, such as extreme temperatures, high and low pressures, shocks and vibrations, and contamination. Electronics, including servo drives, can malfunction or sustain permanent damage in these conditions.
