Scalable Solution for Critical Environments
APC NetworkAIR™ FM-DX 5
Glycol-Cooled Configuration
Glycol-cooled systems are completely charged
and factory tested in a sealed system for reliabil-
ity. In mid to low ambient climates, an
economizer coil can be used to increase effi-
ciency and extend compressor life. Economizer
operation greatly reduces the energy consump-
tion of the system. Water regulating valves
control head pressure.
• System is used with a fluid cooler.
• Factory tested as a sealed system.
• Eliminates the need for field refrigerant piping.
• No requirement for water treatment.
• Economizer option for high efficiency.
• Low maintenance.
Water-Cooled Configuration
Water-cooled systems are completely charged
and factory tested as a sealed system for reliabil-
ity. Cooling towers are used as a source of heat
rejection and can be used to serve multiple
indoor units. Towers utilizing outdoor air require
water treatment.
• System used with a cooling tower or other source
of water.
• Factory sealed and tested system.
• Eliminates the need for field refrigerant piping
• Economizer option for high efficiency
Air-Cooled Configuration
Air-cooled systems are not pre-charged from the
factory, requiring field refrigerant piping. Each
installation requires an engineered piping solu-
tion. APC strongly recommends installation by a
highly qualified refrigeration contractor, to
avoid improper elevation and long piping runs.
• System used with a remote air cooled condenser
• Requires field refrigerant piping
• Low maintenance
