Advanced Roof Top Unit (RTU) Controls

Challenge

Most RTUs operate inefficiently, they lack advanced controls, use constant supply speed supply fan and non-integrated economizer controls.

Objective

Improve operational efficiency of RTUs through use of advanced RTU controls leading to energy and carbon emission reductions between 30% and 50%.

Advanced RTU Controls (ARC)

Install variable-frequency drives on supply fans and retrofit the RTU with an advanced controller having the following control strategies: integrated economizers, variable or multiple speed fan, variable capacity control and demand controller ventilation.
