About Us

Casaire Limited is a wholly owned subsidiary company of Constant Air Systems Limited (CAS). CAS was established in 1965 as a design and contracting company in the field of mechanical heating, ventilation and air conditioning systems.

From an early stage, CAS engineers became aware of the inefficiency of conventional heating systems when serving large open high buildings and began an investigation into anew initiative for heating these type of buildings in the form of an induced air system.
