SAS Coolceil Radiant Chilled Ceilings have emerged as an alternative to traditional air conditioning systems, incorporating a single piece copper element into the rear of a standard ceiling tile.
Coolceil Radiant Chilled Ceilings are as durable as, and visually indistinguishable from standard metal suspended ceilings. Using water as the heat transfer medium, absorbs and removes heat from an occupied space as it flows through the system.
Coolceil Radiant Chilled Ceilings provide between 45 and 65 W/m² (net) of cooling capacity. They radiate cooling downwards and provide quiet, draft free comfort cooling to occupants.
Coolceil Radiant Chilled Ceilings can be used in conjunction with Chilled Beams to meet additional cooling requirements (e.g. solar gain around glazed elevations).
System Features
•Energy efficient - low operating temperatures and pressure drop
•Silent operation
•No moving parts resulting in low maintenance requirements
•Accommodates future layout requirements including demountable partitioning
•Single piece continuous copper element
•Can be installed with voids less than 100mm

An optimal working environment raises the productivity of people. Chilled ceilings by Armstrong help in the attainment of this objective:
Chilled ceilings - a new air-conditioning concept
Most conventional chilled ceilings operate via the forced air principle. Warm air is re-circulated and replaced by recycled and cooled air. This exchange results in a draught of cool air. An additional problem with this system is what is known as the "sick building syndrome". Non-maintained air ducts of an air-conditioning system can blow bacterial pathogens into a room thereby contaminating the air. This can lead to the rapid spread of diseases.
Chilled ceilings based on radiant cooling technology allow for an entirely new way of air treatment - a method that solves both problems. The ceiling panels of radiant cooling systems contain chilled water which flows through tubing mounted on the rear of the ceiling panels. The ceiling panels function as heat exchangers between the room air and chilled water. The ceiling absorbs heat generated by the heat sources in a room and exchanges it with the circulating chilled water.
Operating principle of a chilled ceiling
From a technical viewpoint, a radiant cooling ceiling is simply a large heat exchanger that is suspended from a room's ceiling. It exchanges energy via the room's radiation and convection.
