Rittal SK 3386.540 TopTherm Blue e Roof-Mounted Cooling Unit, 3000 W (3386540)

Rittal 3386540 is a SK TopTherm Blue e roof-mounted enclosure cooling unit with a 3000 W (10,236 BTU/h) refrigeration capacity, supplied for 400-460 V, 3-phase, 50/60 Hz mains. The carbon-steel housing measures 796 x 470 x 580 mm and uses R-513A refrigerant with an e-Comfort controller factory-set to +35 °C. A hydrophobic RiNano-coated condenser and integral condensate evaporation ensure reliable service in demanding industrial environments. Typical use is to remove heat loads from control cabinets housing frequency converters, PLC systems, and other heat-generating switchgear.
