enVerid’s HVAC Load Reduction® (HLR®) products use our Sorbent Ventilation Technology® to improve indoor air quality and reduce HVAC costs in all commercial building types covered by ASHRAE Standard 62.1, the Standard for Ventilation and Indoor Air Quality. All commercial buildings excluding certain health care facilities are covered by ASHRAE 62.1.

Sorbent Ventilation Technology improves indoor air quality by removing contaminants generated by building materials, furniture, and cleaning supplies from indoor air, and by reducing the intake of outside air polluted by exhaust from highways and airports, smoke from industrial parks and wildfires, pollen, and ozone.

enVerid’s HLR 200M and HLR 200R products are also uniquely capable of removing human-generated CO2 from indoor air. Research has linked high levels of CO2 to lower test scores and cognitive function.

Reduced Capital Expenditure on HVAC

By combining enVerid’s Sorbent Ventilation Technology with ASHRAE’s Indoor Air Quality Procedure (IAQP), each HLR module delivers first cost savings of up to $25,000 by downsizing HVAC equipment by up to 20-tons of cooling load and 200 MBH of heating load. Payback periods based on HVAC energy savings for target applications range from zero to five years depending on climate zone, operating hours, energy costs, building-specific installation costs, and utility incentives.

Load Reduction and Energy Savings

By cleaning the air in buildings, indoor air can be safely recirculated. This allows outside air requirements to be reduced by up to 85% using ASHRAE’s Indoor Air Quality Procedure (IAQP). Deploying HLR modules with ASHRAE’s IAQP can also deliver annual HVAC energy savings of up to 40%. The reduction of required outside air reduces the load on the HVAC system which enables the downsizing of new HVAC systems and saves energy, reduces carbon emissions, and extends equipment life.

How HLR Modules Work

Products

enVerid offers three HLR products, all of which reduce first costs and operating costs for new and existing HVAC systems, lower a building’s energy and carbon intensity, and deliver premium indoor air quality. Superior indoor air quality is achieved by using our patented sorbent filters to remove indoor-generated contaminants and by reducing the intake of outdoor pollutants.

enVerid HLR 100C module

HLR 100C

The HLR 100C uses enVerid’s Sorbent Ventilation Technology® to remove VOCs and other contaminants from indoor air so that it can be safely recirculated. HLR 100C modules are integrated with packaged rooftop HVAC equipment by installing them inside standard roof curbs. By cleaning recirculated air, the HLR 100C enables packaged RTU systems to be replaced with smaller tonnage systems which cost less and consume less energy.

The HLR 100C complies with ASHRAE Standard 62.1 and is easily integrated with most standard RTU curbs. Learn more about the HLR 100C module here.

enVerid HLR 100M

HLR 100M

The HLR 100M is a small indoor HLR module designed to easily integrate with a wide range of central or zone-based HVAC systems while delivering significant cost savings. Named HVAC Product of the Year in 2021 by the readers of Consulting-Specifying Engineer magazine, the HLR 100M removes all the contaminants of concern from indoor air so that it can be safely recirculated. The HLR 100M is ideally suited for lower-density existing building retrofit and new construction projects. Learn more about the HLR 100M module here.

enVerid HLR 200M, AHR Expo Product of the Year 2019

HLR 200M

The HLR 200M is enVerid’s award-winning air cleaning product that removes CO2, VOCs and other contaminants from indoor air so that it can be safely recirculated. The HLR 200M is ideally suited for higher-density existing building retrofit and new construction projects, as well as those seeking LEED or WELL certification.

The HLR 200M integrates with custom and semi-custom airside systems, including systems with DOAS and ERV components, in high rise office buildings, schools, universities, and other commercial buildings. Learn more about the HLR 200M module here.

enVerid HLR 200R Module

HLR 200R

The HLR 200R is the rooftop version of the HLR 200M air cleaning product that removes CO2, VOCs, and other contaminants from indoor air so that it can be safely recirculated. The HLR 200R is ideally suited for higher-density existing building retrofit and new construction projects and projects seeking LEED or WELL certification.

The HLR 200R integrates with custom and semi-custom rooftop systems, including systems with DOAS and ERV components, in low rise office buildings, schools, colleges, and other commercial buildings. Learn more about the HLR 200R module here.
