Vertiv™ Liebert® MC Microchannel Outdoor Condenser
High-efficiency outdoor air-cooled condenser with microchannel coil, 28–220kW, reducing refrigerant charge by over 50%.

Solution overview
Higher efficiency and lower refrigerant charge than conventional fin-and-tube condensers
The Liebert® MC Microchannel is an outdoor air-cooled condenser that provides higher efficiency while using less refrigerant. Its aluminum microchannel coil with variable speed fans delivers 30–50% higher full-load efficiency and up to 85% annual energy savings over alternative condensers.
Constructed with an aluminium cabinet, galvanized steel frame and microchannel coil, the Liebert MC is a low-profile, direct-drive, propeller fan-type unit that is quiet and corrosion resistant, with factory-completed wiring requiring only two electrical connections on site.
