ALPHARETTA, GA, July 23, 2021 — LG Air Conditioning Technologies USA has introduced two new split Dedicated Outdoor Air System (DOAS) units, enabling building owners and facility managers to efficiently condition outside air for improved indoor air quality and comfort, without sacrificing flexibility, reliability or ease of integration.

New to the award-winning LG DOAS lineup are 12-ton Split Rooftop DOAS and 1500-2000 CFM Indoor Split DOAS offerings, providing commercial owners and operators with the ability to implement complete end-to-end LG HVAC systems with ease. The new split DOAS models are configured for compatibility with LG's industry-leading Multi V Variable Refrigerant Flow (VRF) outdoor units and integrate seamlessly with LG VRF controls. The new units are optimal for new building and retrofit projects with outside air requirements, such as applications in education, office, retail and hospitality spaces, as well as multi-family housing.

The LG split DOAS units are flexible and economical, and address the needs of multiple applications. With built-in heat recovery units, both the Split Rooftop DOAS and Indoor Split DOAS are easier to install, requiring less labor, and are ideal for applications where roof limitations prevent the use of a packaged rooftop DOAS. The new DOAS feature longer pipe lengths that allow for remote connection to VRF Multi V units as a solution for onsite space restrictions, providing more design flexibility. LG's split DOAS includes a web user interface for remote accessibility along with the option for VRF and DOAS interlocked operation via LGAP. Such features enable seamless integration without the need for third-party platforms.
