RTU Replacement in Denver, Lakewood CO, and Surrounding Communities

Are you dealing with old or new rooftop units (RTUs) that are energy hogs? Are you trying to save energy but don’t have the funding to replace each and every unit? Transformative Wave’s CATALYST is the only solution you need for RTU replacement in Denver. Reduce HVAC energy usage by 25 – 50%!

RTU Replacement in Denver: CATALYST or Bust

The CATALYST is more than a controller and more than a variable frequency drive (VFD). It is a complete HVAC energy efficiency upgrade that includes numerous components, adds 5-6 new sensors and has been developed as an easy-to-install pre-wired kit. When applied, it radically lowers the energy use and improves the overall performance of constant volume HVAC systems. The CATALYST assures proper ventilation, maximizes the use of outside air for free cooling beyond standard economizer logic, and reduces fan energy use by an average of 69%. Transformative Wave has a four year history of success in the field and a great deal of M&V data to support the product’s effectiveness.

The U.S. Department of Energy (DOE) recently commissioned a study with the Pacific Northwest National Laboratory in which the CATALYST was the only RTU retrofit solution conducted in field tests. The study covered CATALYST upgrades on 66 existing rooftop units across the nation in four climate zones and varying building types. Read the full report.

While Transformative Wave’s full CATALYST retrofit solution offers users additional energy savings and advanced features with the eIQ Platform such as fault detection, remote diagnostics, and real-time efficiency and performance verification, some operators are only interested in a supply fan upgrade product. The CATALYST Lite is a response to this significant market sector seeking a simple VFD solution. As part of the CATALYST solution product line, the CATALYST Lite maintains Transformative Wave’s commitment to basic system protections and proper ventilation unlike simple VFDs or low-tech drive products out in the market.
