Rittal Blue e+ Wall-Mounted Enclosure Cooling Unit 1.6-5.5 kW

Product Overview

Blue e+ is Rittal’s most energy-efficient enclosure cooling generation. The wall-mounted units in the 1.6-5.5 kW output categories use speed-regulated components and heat pipe technology for an average of 75% energy savings. Reference variant SK 3187930 delivers 2.6 kW at L35/L35 (DIN EN 14511, 50/60 Hz) with an EER of 2.63 and a seasonal efficiency (SEER) of 6.2, in a 450 x 1,600 x 294 mm, 55.2 kg housing cooled by R-513A (1.07 kg, GWP 631).

A unique multi-voltage capability – 110-240 V 1~ and 380-480 V 3~, 50/60 Hz – makes one unit suitable for worldwide deployments. The internal circuit is rated IP 55 (NEMA 12/3R), the operating range spans -20 to +60 degC, and the e+ touch controller plus optional IoT interface (model 3124.300) and Rittal Scan & Service app provide intelligent monitoring.
