ICSC-1
ICS Series 5-15 Ton
Indoor Ducted Air-Cooled Water Chillers
The SpacePak ICS series of air-cooled water chillers provide
compact, efficient and reliable cooling in applications
where placement of the air-cooled chiller outdoors is
impractical or undesirable. Locating the chiller indoors and
ducting the condenser air greatly minimizes the noise heard
outside to the benefit of the building’s occupants and
neighbors. SpacePak ICS series units are typically installed
near an outside wall or converted window opening for
access to outside air for the intergal air-cooled condenser.
They are ideal for larger homes wanting multiple zones.

Short Water Piping Loop Considerations
In systems with relatively short water piping loops, the volume of the water in the system can be insufficient causing
swings in water temperature and short cycling. In these cases a chilled water storage tank should be installed in the
return water piping before the chiller. This will increase the volume of the water in the system thereby reducing the
fluctuations in return water temperature and reduce compressor cycling. The use of three way valves at the evaporator
coil (in lieu of 2-way valves) and hot gas bypass is also recommended. Typically allow a minimum of 5 GPM per ton of
chilled water storage.
