Transformative Wave’s CATALYST is North America’s Leading Efficiency Solution for Constant Volume HVAC Systems.


The CATALYST is more than a variable frequency drive (VFD). It is a comprehensive HVAC energy efficiency upgrade that converts RTUs into dynamic part load systems, matching the energy use to the true needs of the occupied space. When applied, it is proven to radically lower energy use and improve the overall performance of Rooftop HVAC Units (RTUs). The CATALYST uses unique logic and sequences to assure proper ventilation, maximize the use of outside air for free cooling beyond standard economizer logic, and reduce fan energy use by an average of 69%. Transformative Wave has five years of success in the field and multiple independent third-party trials have demonstrated the product’s effectiveness. The CATALYST is shipped as an easy-to-install pre-wired kit that includes everything required for a complete installation.

Dillett Mechanical Service is proud to partner with Focus on Energy to provide incentives to our customers for making their buildings more energy efficient.
