Improved Air Quality, Lower HVAC Costs

The HLR 15R is enVerid’s award-winning air cleaning product that removes CO2 and contaminants of concern from indoor air so that it can be safely recirculated. This solution reduces first costs and operating costs for new and existing HVAC systems, lowers a building’s carbon footprint, and improves indoor air quality while also generating LEED® and WELL building credits. Indoor air quality is improved by removing indoor-generated contaminants and reducing the intake of outdoor pollutants. The HLR 15R solution is compliant under ASHRAE 62.1 and IMC 403.2. The HLR 15R module is designed for outdoor use, typically on a rooftop. The HLR 200M module is a model designed for indoor installations.

How the HLR 15R Works

Indoor Air Scrubbing – One or more HLR 15R modules can be installed on the return air side of an air handling unit (AHU). Air is drawn into the 15R by internal fans, which blow the air through sorbent cartridges that capture and remove carbon dioxide (CO2) and contaminants of concern from the air stream. Without producing any byproducts, the HLR 15R then blows clean air back into the return. 

Automatic Self-Cleaning – The sorbents are designed to release captured contaminants upon heating. The 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. 

Outside Air Intake Reduction – By cleaning recirculated air, outside air ventilation rates can be safely reduced by up to 85%, and new HVAC equipment can be downsized, using the ASHRAE Standard 62.1 IAQ Procedure. 

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 performing these calculations easy.

Broad Applicability

The 15R is ideally suited to integrate with custom and semi-custom airside systems, including systems with dedicated outside air systems (DOAS) and energy recovery ventilation (ERV) components, in office buildings, schools, and other commercial buildings. 

Proven, Award-Winning Technology

Hundreds of HLR modules have been specified and installed around the world by leading consulting engineers and HVAC contractors. Air cleaning efficiency has been validated by ASHRAE 145.2 testing, and energy savings have been field validated by multiple utilities who have provided incentives for installing HLR modules as well as by the U.S. Department of Energy. Unlike many other air cleaning technologies, independent lab tests show that HLR modules do not produce any byproducts. In 2019, HLR technology received the AHR Expo Product of the Year Award, the most prestigious award for an HVAC product.
