HLR 15R Outdoor Module

How HLR Works

The diagram below illustrates the HVAC operation using ventilation only and ventilation and scrubbing.

HLR 15R Outdoor Module has Four Integrated Capabilities

Indoor Air Scrubbing (Adsorption Mode)

A fraction of the return air stream is directed through the HLR 15R Module to remove indoor-generated contaminants using a blend of sorbents that capture carbon dioxide (CO₂) along with a wide range of volatile organic compounds (VOCs), aldehydes, ozone, acids and particulate matter (PM2.5) resulting in cleaned air that flows back into circulation.

Outside Air Intake Reduction

Outside air reduction leads to lower cooling and heating energy consumption2 and reduces the intake of outdoor-generated pollutants. By following ASHRAE Standard 62.1 IAQP, HLR Technology enables significant outside air reduction relative to the typically prescribed amounts, while maintaining indoor air quality.

Automatic Self-Cleaning (Regeneration Mode)

The sorbents are designed to release captured contaminants upon heating. The HLR 15R Module is equipped with a built-in heater and performs a periodic regeneration process to clean the sorbents and expel contaminants outside the building. Regeneration is managed for optimal performance and minimal energy use.

Monitoring and Reporting

HLR software communicates continuously with the onboard sensors to record, report and optimize all aspects of the HLR 15R Module’s operation. The system provides secure, real-time reporting of IAQ and operating parameters to the enVerid Cloud™.

1 The mass balance analysis is performed per contaminant and per zone to ensure all contaminants are properly below their established limits. These “per zone” outside air CFMs are summed to yield the total ventilation required for the building. enVerid’s IAQP calculator makes it easy.

2 When economizer operation is favorable, outside air is increased and the HLR module is in standby.
