enVerid Systems
HLR modules remove carbon dioxide and VOCs from indoor air, enabling significantly less outside air to be brought into a building to be conditioned. Can be retrofit onto existing air distribution systems. System automatically self-cleans the cartridges that absorb air contaminants, regenerating them for reuse. Cartridges require replacement after a year. System is designed to meet ASHRAE 62.1 guidelines under the IAQ Procedure.
