Rooftop (RTU) HVAC System
OVERSIZED, ISOLATED, INVISIBLE, UNMANAGED, DYSFUNCTIONAL, NEGLETED, UNACCOUNTABLE, INEFFICIENT, UNINTELIGENT, FORGOTTEN, AND CLUNKY. What can be done to bring efficiency and accountability to RTUs?
The Catalyst – A complete Retrofit Solution
No matter the stage of your energy efficiency strategy, the CATALYST can meet you where you’re at:
Optimized your RTU system to give you access ANYWHERE. With our solutions, you have real-time energy consumption monitoring and assurance that the CATALYST’s high-tech monitoring system will give you around the clock access to your HVAC assets such as:
Web-Based Access – Access the system anytime, anywhere from any authorized computer with internet connection
Demand Reduction – Use preset parameters or monitor an automated signal from the local utility to limit consumption
Real-Time Energy Consumption Monitoring – Capture and report the actual energy savings of the installed devices
Building Management Controls – Easily integrate with most BMS or use as its own open protocol BMS capable of controlling lighting, HVAC and key card access day-to-day operational pains are eliminated
Fault Detection and Diagnostics – Actively monitor performance of equipment including abnormalities which trigger alarms and notifications
Preventative Maintenance Cost Avoidance – By monitoring the performance and system operating temperatures, insight to equipment conditions can enable maintenances work to be schedule as needed.
Our system can upgrade your old RTUs by adding modern features such as economizers, variable frequency drives, and building automation solution. With this system build owners can see large savings compared to the energy costs for their building. By combining VFD with Demand Control Ventilation (DCV) and both Advanced and Predictive Economization, the CATALYST significantly reduces HVAC energy consumption while also providing powerful tools that empower facility and energy managers.
The CATALYST system:
Industry Evaluated – The Department of Energy (DOE) validated the CATALYST energy saving strategy
Strong utility Support – Utilities across the country offer prescriptive incentives for CATALYST
Easy Integration – Pre-wired kit can be installed into existing HVAC system or total retrofit
Improved Efficiency – Demand Control Ventilation and Advance Economization improve efficiency
Go beyond Automation – Enhanced insight into the equipment provides detailed fault detection and diagnostics

The CATALYST will transform your HVAC system into a Smart Energy Saving Machines.
Intelligent Solution for RTUs
Extends the equipment life
Retrofitting existing RTUs with advanced packaged controllers improves functionality and offer potential savings of up to 50 percent with a typical payback of one to four years. For RTUs serving large spaces with intermittent occupancy like auditoriums, cafeterias, parking garages, and conference rooms, DCV can offer big savings. The system detects occupancy by measuring the level of carbon dioxide present in the return airstream. High levels of carbon dioxide indicate the presence of people; low levels indicate their absence. This strategy decreases the amount of ventilation produced by the HVAC system during low-occupancy periods, and can result in energy savings.
Economizer save energy by drawing in outside air to cool the building instead of using mechanically refrigerated air. In many applications, a fully functioning economizer can cut a building’s total energy consumption by up to 20 percent.
