Engineered Systems recently featured the HLR 100M HVAC Load Reduction Module, saying:
The HLR 100M is designed for simple indoor installation with a wide variety of HVAC systems. The new module does not require exhaust ductwork and has a small footprint and wide range of installation orientations, including stacking and hanging individually or in clusters. The HLR 100M is ideal for both new construction and retrofits, allowing buildings, such as offices, schools, and conditioned warehouses, to achieve IAQ goals and significantly reduce their annual HVAC energy costs.
