Energy-Efficient Cooling for Industrial Enclosures
Rittal Blue e+ technology combines passive heat-pipe cooling with speed-regulated compressor refrigeration to adapt cooling performance to the actual thermal load. When ambient conditions permit, heat-pipe operation transfers heat from the enclosure without relying solely on the compressor, helping reduce electrical consumption and mechanical wear.
When greater cooling capacity is required, the active refrigerant circuit supplements the heat-pipe system to provide up to 2.0 kW of cooling output at L35 L35. The separate internal and external airflow circuits help prevent ambient contamination from reaching installed equipment, while the e+ controller provides intelligent temperature regulation and convenient system monitoring.
