The efficacy of enVerid’s HLR® (HVAC Load Reduction) solution is based first and foremost on the company’s patented sorbent materials. enVerid’s game-changing approach to indoor air quality management is achieved using a combination of unique sorbent materials. These sorbents, highly selective in their ability to remove unwanted indoor air contaminants, represent breakthroughs in materials and chemical science discovered by national laboratories and university research groups, and further developed by enVerid’s engineers and scientists. The patented sorbent technologies applied for the first time to indoor air treatment include:
Each HLR module has a set of cartridges that house the patented sorbents. These cartridges facilitate the compact, modular design that lends itself to scalability for different air flow rates and building sizes. The HLR module repeatedly reuses the sorbents through a cyclical process known as Temperature/Concentration Swing Adsorption (TCSA).
In the adsorption phase of the TCSA cycle, indoor air flows through the sorbents. Contaminants are captured and retained by the sorbents while cleaned air flows back into the building. Sensors in the HLR module determine when sorbent elements are saturated, and the system automatically switches to regeneration mode.
In the regeneration phase, the HLR module is sealed off from the building circulation by means of its automated dampers. Sorbents are then flushed with heated air to purge them of adsorbed contaminants. Once the sensors determine that the sorbents have returned to their clean state, the unit reverts once again to air-scrubbing adsorption mode.
The system simultaneously regenerates all sorbents. This automated process enables a virtual maintenance-free system with a single set of cartridges lasting an entire year.
