Norlake 170300S Air Diffuser R449A

Product Description

The NORLAKE 170300S is an air diffuser engineered for use with R449A refrigerant in commercial refrigeration systems. Air diffusers distribute conditioned air evenly across the refrigerated space, maintaining consistent temperature zones and reducing hot spots that can compromise product storage. This unit measures 40.0 inches by 27.0 inches by 4.0 inches and weighs 7 pounds, making it a substantial component suited for walk-in coolers, walk-in freezers, and similar commercial cold storage applications. Installation is typically performed by a licensed refrigeration technician or commercial HVAC-R service professional.

This diffuser is designed for systems charged with R449A, a low-global-warming-potential HFC blend commonly used as a retrofit or new-installation refrigerant in medium- and low-temperature commercial refrigeration equipment. Its profile of 4.0 inches keeps the unit low-profile relative to its coverage area, allowing for installation in spaces where ceiling or wall clearance is a consideration. It is well-suited for food service, grocery, and cold storage environments where precise airflow management is required to meet health and safety temperature standards.

Installation Notes

Installation should be performed by a licensed refrigeration or HVAC-R technician familiar with commercial cold storage systems. Shut down and de-energize the refrigeration unit and allow the system to reach a safe working temperature before beginning any service work. Verify that the mounting surface and airflow direction align with the existing evaporator and return air path before securing the diffuser. Follow all applicable local mechanical codes and manufacturer guidelines during installation.
