Cooling Interface Units (CIUs)

Cooling Interface Units (CIUs) In Luxury Apartments

A Cooling Interface Unit (CIU) is a discreet and highly efficient module that delivers comfort cooling from a central chilled water source directly to each apartment or dwelling. Ideal for premium residential developments, CIUs provide silent, effective cooling via fan coil units or underfloor systems—without the need for unsightly external plant or individual condensers.

Here is an example of a typical CIU in use within high-end developments:
