InRoom Cooling Unit Configurations
Fluid Cooled (Glycol)
InRoom Fluid Cooled (Glycol) systems are
completely charged and factory tested in a sealed
system for reliability. In mid to low ambient
climates, an economizer coil can be used to
increase efficiency and extend compressor life.
Economizer operation greatly reduces the energy
consumption 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 provides high
efficiency.
• Low maintenance.
The InRoom Fluid Cooled (Glycol)
System with Economizer is configured
with both the glycol factory sealed system
and an Economizer coil. During cold
ambient conditions, the compressorized
system will shut down and utilize the cold
outdoor air to cool the glycol system,
rerouting it from the heat exchanger to the
Economizer coil for efficient operation.
