Data center solutions powering the digital economy

Overview

The brochure covers air-cooled chillers, precision air units, liquid-cooling connectors and CDU components, pump stations, solid-state transformers, heat-recovery modules and fan walls. Each section lists the relevant components (Turbocor compressors, VFDs, micro-channel and plate heat exchangers, balancing valves, couplings, sensors) with headline performance figures.

On the cooling side: Turbocor oil-free compressors are quoted with up to 38 °C maximum chilled-water output for air-cooled chillers; all-aluminium micro-channel heat exchangers are claimed to give up to 30% better performance with lower refrigerant charge and glycol compatibility for dry/free cooling; gasketed plate heat exchangers reach an approach temperature as low as 1 °C.

On the electrical side, iC7 ULH air-cooled pump drives are quoted at 3-5% THDi or less, with ultra-low supraharmonics and no common-mode voltage. An Advanced Active Filter with SiC switches is quoted at 98.2% efficiency. The solid-state transformer converts MV AC directly to LV DC with a single 11 MW converter.

For liquid cooling, OCP-inspired UQD/UQDB couplings are used in-rack and FD83 couplings out-of-rack on CDU loops. The figures are the manufacturer's own promotional values and their test conditions are not detailed in the brochure.

Using it in design

• In the cooling-plant builder keep a component list per subsystem (chiller, CDU, pump skid, heat recovery) with fields for maximum chilled-water temperature, HX approach temperature and VFD THDi.
• When liquid cooling is selected, require the in-rack and out-of-rack quick-disconnect types to be specified.
• Model low-harmonic drives as reduced harmonic sources in the power-quality calculation.
