Light Commercial Buildings Can Save on HVAC and Energy Costs

enVerid Systems is excited to announce the launch of the HLR 100C, a new sorbent filtration module that fits inside standard roof curbs and works with any rooftop unit (RTU). The HLR 100C is the latest addition to our family of HVAC Load Reduction^® (HLR^®) air cleaning systems that use Sorbent Ventilation Technology^® (SVT^®) to capture pollutants from indoor air so that outside air ventilation requirements can be reduced without compromising indoor air quality. By reducing outside air requirements, buildings can save on HVAC equipment and operating costs by using smaller, more energy efficient systems.  

Designed for the packaged RTU market, the HLR 100C offers fast payback periods for a wide array of commercial buildings including schools, offices, restaurants and retail stores. The HLR 100C comes in three different sizes that can pair with any commercially available RTU. Due to the compact size of the module, local curb manufacturers can easily integrate the module into standard RTU curbs. This simple integration drastically reduces installation costs, making low-tonnage RTUs with SVT more cost effective than traditional RTUs. 

How SVT Works 

SVT is a patented technology that uses sorbents, which are materials that chemically bind with gaseous pollutants in the air, to remove ozone and a wide range of volatile organic compounds (VOCs) including formaldehyde from indoor air. By doing so, SVT makes it safe to recirculate more indoor air. Use of SVT is fully compliant with ASHRAE Standard 62.1 – Ventilation and Acceptable Indoor Air Quality and the International Mechanical Code (IMC). SVT can also be used to earn additional LEED and WELL credits.  

How the HLR 100C Works 

The HLR 100C works in a side-stream configuration with the curb’s return section: its integral fan diverts a portion of the building’s return air through the SVT filtration section and then returns the cleaned air for conditioning by the RTU. The SVT filters are designed to last two years and can be easily replaced through access doors on the curb once they reach their saturation point. 

The HLR 100C was designed specifically to minimize integration costs: in-field installation can be as easy as plugging the module into the RTU’s courtesy outlet. Each module takes a standard 120V power supply and requires very little power: between 190 and 350 W depending on size. Additionally, the module can be turned on and off automatically, in sync with the RTU, by utilizing the pressure sensor or controlled directly through the dry contact – both provided in the electronics box. Finally, the system includes a speed controller, so balancing the unit is as easy as turning a knob.  

Benefits of the HLR 100C 

The HLR 100C offers several benefits for building owners, operators, and occupants including: 

• Lower system costs: By using the HLR 100C, you can replace your RTU with a smaller tonnage system that costs less upfront and, in new construction, reduce the footprint, ductwork and power required to support the RTU.  

• Decreased energy consumption: By recirculating more indoor air and reducing the amount of outside air needed for ventilation, you can save up to 40% in annual HVAC energy consumption and lower your utility bills. You can also reduce your peak demand charges by using less electricity during peak hours. 

• Improved indoor air quality: By removing VOCs from indoor air, you can improve the health and comfort of your building occupants. You can also achieve higher standards of indoor air quality such as LEED and WELL certification. 

• Reduced carbon emissions: By using less energy and relying less on fossil fuels, you can reduce your building’s carbon footprint and contribute to global decarbonization efforts. 

The HLR 100C is available exclusively through enVerid reps and is compatible with most RTUs on the market. Reference designs are now available for Trane Precedent RTUs and others will follow soon.
