The automated regeneration process is one of four integrated capabilities that enable a proven, systematic solution for effectively and efficiently cleaning indoor air.
The essence of the HLR® (HVAC Load Reduction) solution is being able to selectively capture the unwanted contaminants prevalent in indoor air (adsorption mode) and periodically regenerate the sorbents for repeated cyclical use (regeneration mode). The relatively low-heat regeneration phase is a technological breakthrough as it allows the process to be automated and completed in situ. Sophisticated algorithms manage the timing, duration and temperature of the regeneration cycle.
Sensors within each HLR® module continuously monitor the sorbents for saturation. When deemed necessary, the system switches from adsorption mode to regeneration mode, during which the HLR® module is sealed off from the building circulation by means of its automated dampers. The sorbents are flushed with slightly heated air (40-60⁰C/104-140⁰F) to purge them of captured contaminants. Once the HLR® module determines the sorbents have returned to their clean state, the unit can revert to air-scrubbing adsorption mode. The process is done automatically one to three times a day and takes several minutes to complete.
