SpacePak averages 250 CFM per ton cooling versus 400 CFM for conventional systems. SpacePak’s 6-row coil provides a greater
temperature drop of the air passing through the coil, typically 24˚ to 28˚F. Specially designed blower pressurizes the duct system 5 to 6
times higher than conventional duct systems. Air exiting into the room is traveling at high velocity, approximately 2000 Ft./Sec. creating
floor to ceiling circulation of the air in the room. The air under pressure in the duct system expands as it is released into the room.
More moisture is taken out of the air because it is in contact with the coil longer, driving it to a lower dew point temperature.
Drier air increases the body’s ability to cool itself by perspiration evaporating off the skin. The SpacePak system, by lowering the RH,
can run at higher temperature settings. By setting the temperature to 72˚ instead of 70˚, customers can save 15% on their annual
cooling energy cost – without sacrificing comfort.
