In addition to the CULUS listing, Rittal cooling units and fan-and- filter units also have a UL listing in the new “FTTA” (Environmental- ർ Rittal expands Blue e+ cooling unit generation rated Accessories for Enclosures) category. “With FTTA approval, the type rating/IP protection class of the climate-controlled enclosure is certified by UL. This means that one of our user group most frequently asked questions has an authoritative response,” says the climate control specialist. 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. “Thanks to the high energy efficiency of new …‘‘Ž‹‰ —‹–•ǡ •ƒ˜‹‰• ‘ˆ —’ –‘ ͷ͵τ ƒ”‡ possible – as a number of test results show”, Steffen Wagner pointed out.
