Improved Air Quality, Lower HVAC Costs

The HLR 200R is enVerid’s award-winning air cleaning product that uses Sorbent Ventilation Technology® to remove CO2 and contaminants from indoor air so that it can be safely recirculated. This solution reduces first costs for new construction and lowers operating costs for all 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 200R solution is compliant under ASHRAE 62.1 and IMC 403.2. The HLR 200R module is designed for outdoor use, typically on a rooftop. The HLR 200M module is a model designed for indoor installations.

How the HLR 200R Works

Indoor Air Cleaning – One or more HLR 200R modules can be installed on the return air side of an air handling unit (AHU). Air is drawn into the 200R by internal fans, which blow the air through sorbent filters that capture and remove carbon dioxide (CO2) and other contaminants from the air stream. Without producing any byproducts, the HLR 200R then blows clean air back into the return. 

Automatic Self-Cleaning – The sorbents are designed to release captured contaminants upon heating. The 200R module is equipped with a built-in heater and performs a periodic regeneration process to self-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 HLR 200R 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, universities, and other commercial buildings. 

Proven, Award-Winning Technology

Over 1,000 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, enVerid Sorbent Ventilation Technology received the AHR Expo Product of the Year Award, the most prestigious award for an HVAC product.
