The PAH Series is engineered for integration into new and existing indoor HVAC split systems and Air Handling Units (AHUs). Designed for coil-mounted installation, the system provides continuous Ultraviolet Germicidal Irradiation (UVGI), also referred to as Germicidal Ultraviolet (GUV), to evaporator coil surfaces to help limit microbial growth and biofilm accumulation while supporting heat-transfer efficiency and overall HVAC performance.

The PAH-N08 is configured for a single UV-C lamp, while the PAH-N12 accommodates dual UV-C lamps to provide increased irradiance where required. Model selection is based on airflow conditions and project objectives to ensure appropriate UV-C exposure for the intended application.

UV-C performance within air handling systems depends on airflow, dwell time, and irradiance. When enhanced airborne pathogen reduction is required, the system may be configured to provide calculated UV-C exposure within the moving air stream in addition to continuous coil irradiation. Air stream performance is determined by defined operating conditions while maintaining system aerodynamics and protecting Total External Static Pressure (TESP).

Construction: Grade 304 stainless steel and non-corrosive aluminum.

Compliance: Manufactured in the United States; supports Build America, Buy America (BABAA) requirements.
