Revolutionary compact design fits inside standard roof curbs from leading HVAC manufacturers

enVerid Systems, a leading provider of solutions to reduce the cost and carbon emissions of heating, ventilating, and air conditioning buildings, announced today the HLR 100C, the newest addition to enVerid’s family of HVAC Load Reduction® (HLR®) products. The HLR 100C is engineered to fit inside standard roof curbs from leading HVAC manufacturers, making it easy for packaged rooftop units (RTUs) to be designed or replaced with smaller tonnage systems that cost less and consume less energy. The HLR 100C is ideal for a wide range of building types that utilize packaged RTUs including schools, commercial offices, medical offices, outpatient clinics, public assembly spaces, retail stores, and restaurants. 

The HLR 100C expands the range of new and existing buildings that can benefit from enVerid’s award-winning Sorbent Ventilation Technology® (SVT®), which filters harmful contaminants from indoor air so that indoor air quality can be maintained with less outside air ventilation. Reducing outside air ventilation reduces equipment sizing requirements to save on first costs, lowers ventilation energy use to support energy efficiency and decarbonization goals, and makes buildings more resilient to polluted outside air. The HLR 100C can be applied on any commercial building where packaged rooftop units are being designed or replaced. 

Daikin will be the first company to employ an HLR 100C with installations underway of two HLR 100C modules inside roof curbs at its Design Center in Lynbrook, Long Island. 

The HLR 100C is available through enVerid’s manufacturer representatives for the plan and spec market and through manufacturer representatives and energy services companies for the owner direct service retrofit market. The HLR 100C is available in a variety of curb configurations compatible with most standard rooftop units. Reference designs are currently available for Daikin’s light commercial rooftop units and Rebel® commercial packaged rooftop systems, and Trane Precedent® rooftop units.
