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
