Variable Frequency Drive Solution Protects and Cools VFDs

WEATHERFLO HD features high-performance, shielded impellers, delivering integrated cooling. Robust construction can withstand 100 to 500 HP drive operation, suiting a broad range of outdoor application requirements. Plus, the flexible back panel design facilitates horizontal or vertical panel installation from the rear for increased safety and ease-of-setup.

WEATHERFLO HD is designed and tested for superior protection and long-lasting performance. Back panel loading is simplified through the use of two assembly options: the populated back panel is mounted from the rear of the enclosure, or the frame can be lowered onto the populated back panel. These innovative methods facilitate easier and safer installation with fewer personnel.

Heavy-duty aluminum construction withstands harsh elements, and stainless steel mesh screens come standard on the top and base to protect against debris ingress as well as animal and human interaction. Featuring a recessed louver design, WEATHERFLO HD is flush on the front side, minimizing potential interference. White polyester painted finish offers low solar absorption and optional accessory impeller packages provide 840 actual CFM of exhaust airflow per impeller. The WEATHERFLO HD solution has been strength tested to a two-times safety factor to ensure the ability to safely support VFDs up to 500 HP and is UL Type 3R compliant.

"The Hoffman WEATHERFLO family of enclosures features a forced-air ventilation system for cooling drives or other high-heat producing equipment in outdoor applications," said Garrett Potvin, Hoffman product manager. "With the addition of the higher drive HD models, WEATHERFLO now offers the most complete pre-assembled solution for meeting the demands of heavy-duty VFDs in extreme outdoor conditions across the globe." Potvin adds, "Featuring integrated cooling, WEATHERFLO HD provides a complete solution, saving you time and protecting your VFD investment."

WEATHERFLO HD solutions are available in one- or two-door configurations. Selectable bases, covers and tops are designed to meet specific needs. Solid or vented base styles are available, as well as standard or heavy duty rear covers. Customers can also select from pagoda or solid top styles. Enclosures ship as separate components, simply assemble onsite and can be ganged together for large applications.
