Packaged Roof Top Units
A roof top unit is a complete packaged unit; it incorporates all the controls and hardware in single unit. They are commonly used on large open plan spaces such as warehouses and supermarkets. They are individually tailored to the application; the airflow rate can be altered on installation to satisfy the sensible / latent cooling design load exactly.
Commonly mounted on rooftops, they can be installed in many configurations including at ground level.
One main benefit is that they can incorporate heat recovery and free cooling modules which can reduce annual running costs dramatically.
