Introduction to the Catalyst EEC


We want to thank you for the opportunity to introduce the CATALYST: Efficiency Enhancing Controller. This patent-pending retrofit technology adds dynamic control to constant volume HVAC systems and produces dramatically more efficient operation. It represents a new, unprecedented frontier of energy savings opportunities. It is the result of classic ingenuity combined with the capabilities of some of the world’s leading manufacturing firms.

Exclusive distribution rights for the CATALYST are held by Transformative Wave Technologies (TWT), a wholly owned subsidiary of the Performance Mechanical Group. TWT developed the technology in-house, has proven the savings potential in the field, and brought the technology to the marketplace. In 2009, Yaskawa America was selected as the manufacturer for the CATALYST controller.

The CATALYST technology is built on proven hardware that has been utilized in the industrial and commercial sectors for decades. At the same time it makes use of the latest technological advances in HVAC system control. The CATALYST controller has a small footprint which enables it to be easily installed inside the HVAC equipment cabinet. It integrates readily with existing thermostats or building management systems. The technology combines several well-practiced efficiency measures with our proprietary Opti-Run fan control logic to create a highly intelligent system. This custom microprocessor-embedded program effectively manages the system’s operation without compromising comfort or indoor air quality.

The CATALYST has a short return on investment (ROI), especially when combined with utility funding. Virtually any existing HVAC unit can be retrofitted with the CATALYST to achieve dramatic energy savings. Options for improving the efficiency of older existing HVAC equipment have historically been limited or economically unfeasible. The CATALYST will make a major contribution toward the energy conservation goals of utilities, business operators, and public entities.
