HVAC Load Reduction Module
HLR Outdoor version reduces the OA requirements, allowing downsizing of the other HVAC equipment. The HLR 15R Outdoor Module is an air scrubbing solution that contains regenerative sorbent cartridges, along with embedded web-accessible controls and sensors. Individual or multiple HLR modules can be used depending on the building size. The HLR modules can be retrofitted into an existing HVAC infrastructure or installed in new construction or renovation. The HLR 15R Module is designed for outdoor use, typically on a rooftop. The HLR 15M Module and the HLR 14M Module (not shown) are available for indoor installations.

The HLR 15R Outdoor Module supports IoT connectivity and is linked to the enVerid Cloud using a secure cellular connection. End-to-end encryption and system hardening provide additional layers of security. Facility managers and engineers have 24/7 access to a dashboard with IAQ measurements with a secure login to the enVerid Cloud, HLR module status and the energy savings.
ASHRAE Standard Compliance
The HLR 15R Indoor Module is compliant with ASHRAE 62.1 Indoor Air Quality Procedure (IAQP), the preferred approach to achieve energy efficiency and indoor air quality (IAQ). Introduced in 1981, IAQP is a performance-based design procedure that determines outdoor air intake rates based on an analysis of contaminant sources and air cleaning capacity to stay below recommended contaminant concentration limits.
The ASHRAE 62.1 Standard recognizes that “The IAQP may allow for a more cost-effective solution to providing good air quality.” Additionally, “The IAQP may also be used to achieve better air quality than VRP.”
The cleaning efficiency for HLR modules was tested by a third-party lab in accordance with ASHRAE Standard 145.2 – Laboratory Test Method for Assessing the Performance of Air-Cleaning Systems.
