Variable Speed Drive Hot Aisle Containment Fan Wall Unit Modular Ahu for Ai Infrastructure Racks

Product Description

Product Description

The Fan Wall Unit is a modular precision cooling solution for data centers, consisting of multiple EC fans arranged in parallel. It replaces traditional CRAH units and is specifically designed for AI high-density computing clusters and hyperscale data halls.

Key Advantages:

--Energy Efficiency – EC fan efficiency up to 98%, PUE as low as 1.2
--Built-in Redundancy – Single fan failure triggers automatic compensation – zero downtime
--Precision Air Distribution – Scroll-less design + CFD airflow simulation eliminates hot spots
--Scalable – Configure fan quantity on demand, supports N+N redundancy
--Plug & Play Installation – No raised floor required – wall mount or floor stand directly

Product Feature

The Fan Wall Unit (Air Wall) is designed for next-generation data halls. It utilizes a large surface area chilled water coil and a multi-fan array to move massive volumes of air through the cold aisle with minimal pressure drop:
