Critical and Technical Environments
HVAC Solutions for Data Centers and Mission-Critical Environments
Solutions for precision climate control, operational continuity, energy efficiency, and thermal management in data centers, IT rooms, edge data centers, NOCs, and server rooms.
ASHRAE maintains a technical series specifically for data centers and has published ANSI/ASHRAE Standard 90.4-2025—Energy Standard for Data Centers—as well as materials on thermal guidelines, edge computing, and the expansion of liquid cooling in data centers.
Data centers require precision climate control, high availability, and energy efficiency. We provide comprehensive solutions for mission-critical environments, integrating cooling generation, heat rejection, precision units, hydraulics, filtration, air distribution, ductwork, insulation, and technical accessories.
