LIEBERT® MC™ MICROCHANNEL COIL CONDENSER

As IT budgets constrict, data center
managers require new, higher levels of
energy e iciency to provide the
innovations and technologies that today’s
critical business needs demand.

The Liebert® MC Condenser from Vertiv™
is an air-cooled condenser designed to
deliver energy e iciency. With an
exclusive microchannel coil design, this
condenser o ers a highly e icient, system
matched heat rejection solution that
reduces energy costs and operational
expenses.

EFFICIENT, QUIET AIR COOLED CONDENSER

Liebert MC Condenser Energy Savings – Reduced
Operating Expenses

Liebert MC condenser operates with higher e iciency than fin and tube
condensers, with an annual savings of up to 85%. The savings are even greater
when the flooded receiver system winter operation option is applied.

Standard Ambient Systems

30 Ton Liebert DS @ 100% Load

The Liebert MC Condenser:

 Improves unit and system e iciency at

full and partial loads

 Increases condenser full load energy

e iciency by 30-50%

 Reduces refrigerant volumes and

decreases refrigerant charge levels in
matched condensers – by more than
50% on condensers without flooded
receiver systems and more than 20%
on condensers equipped with flooded
receiver systems

 Is compatible with Copeland® Digital

Scroll™ Technology compressors

Lowest Total Cost of Ownership:

 Electrically Commutated (EC) Fans

reduce annual condenser energy
requirements 50-95% over traditional
condensers

 Liebert MC condenser reduces annual

energy requirements of Computer
Room Air Conditioning (CRAC)
systems by 5-10% (15-25% for flooded
receiver systems)

 Reduced refrigerant requirements

- lower installation cost

 Microchannel coil provides enhanced

energy e iciency and 20-50% lighter
installed weight
