Technology keeps evolving. Your existing CRAC and CRAH units can too. Upgrades such as next-generation microprocessors and direct-drive, variable-speed EC fans save energy, while reducing maintenance costs and environmental impact. Data Aire also maintains high stock levels of components and parts. So whether you need a compressor, a control module, or virtually any other key piece of hardware, you can expect responsive service, regardless of the age or vendor of your system.
