    Family of HVAC Load Reduction (HLR®) modules.

The newest addition to enVerid's family of HVAC Load Reduction (HLR) modules is the HLR 100Z which extends the reach of the company’s products to the individual building zone.

Similar in size and sound to Variable Refrigerant Flow (VRF) terminal units, the HLR 100Z easily fits inside most plenums and mechanical spaces serving one or more zones.

The HLR 100Z works with most commercial building HVAC systems and is ideally suited for those served by VRF, active chilled beams, water source heat pumps, and other de-coupled heating and cooling systems.

The HLR 100Z may be used to reduce outside airflow, heating and cooling load, electrical load, refrigerant charge, system weight, and cost – resulting in savings on equipment and energy use and lower carbon emissions.

When applied with ASHRAE's IAQ Procedure, the HLR 100Z can make building electrification goals easier and more cost-effective to achieve.

Each HLR 100Z can offset 3-15 tonnes of peak cooling load and reduce HVAC energy use by up to 40 per cent.

This in turn can reduce HVAC system electrical requirements by up to 40 amps, refrigerant charge by up to 10 pounds, and system cost by up to 30 per cent.

The HLR 100Z can also be used to earn up to nine LEED points in the Indoor Environmental Quality, Energy & Atmosphere, and Innovation credit areas using the US Green Building Council's LEED BD+C Minimum Indoor Air Quality Performance: IAQP Compliance Path pilot credit.

CEO of enVerid Systems, Christian Weeks, said the market has moved to smaller, decentralized HVAC system designs.

He said enVerid has responded with new products to simplify and expand the applications that can be served with the company’s innovative Sorbent Ventilation Technology that is at the core of all HLR modules.

“In 2023 we launched the HLR 100C to expand from the applied market into the packaged rooftop market,” Weeks said.

“With the addition of the HLR 100Z for smaller zones, we now have a cost-effective solution to implement Sorbent Ventilation Technology and ASHRAE's IAQ Procedure across the entire commercial HVAC market including the rapidly growing segment of the market served by VRF, active chilled beams, water source heat pumps, and other decentralized heating and cooling systems."

enVerid’s Sorbent Ventilation Technology (SVT) filters harmful gaseous contaminants from indoor air, reducing the need for expensive, energy-intensive outside air ventilation to maintain indoor air quality.

Senior vice president of products & engineering at enVerid, Alex Goodwin, aid the initial market response to the HLR 100Z has been extremely positive owing to its compact size and flexible integration options.

"enVerid continues to innovate, engineering its HLR modules into smaller form factors to broaden the HVAC applications served with SVT," Goodwin said.

“With a focus on smaller-scale spaces, the new HLR 100Z delivers the benefits of SVT and the IAQ Procedure to decentralized HVAC systems such as VRVs that are increasingly in demand."

Recent updates to ASHRAE standards make design and implementation of all HLR modules easy for the engineer and cost-effective in today's pressing ventilation scenarios:

Over 1,000 HVAC systems with SVT have been installed into commercial, academic, and government buildings globally over the past 10 years in full compliance with ASHRAE Standard 62.1 and the International Mechanical Code. SVT can also be used to earn LEED and WELL points.
