Computer room air handlers (CRAH) units are specialized cooling systems designed for data centers and other mission-critical environments where maintaining optimal temperatures is essential for equipment performance and reliability. CRAH units use chilled water from an external source to cool the air, unlike traditional air conditioning units. This enables them to provide more energy-efficient and precise temperature control.
Commonly used in data centers, server rooms, and other high-density electronic environments to ensure proper heat dissipation, CRAH units prevent the overheating of sensitive equipment and enhance overall system performance.
FläktGroup® SEMCO® CRAH Units
Koch Applied Solutions partners with FläktGroup® SEMCO® to offer CRAH systems that keep sensitive equipment running by cooling heat generating servers in data center applications. SEMCO systems are energy efficient, designed for medium to large-sized data centers, and easy to expand if more room is needed.
SEMCO CRAH units are critical to the data center servers so they are designed to reliably keep servers running 24/7.
