Cooling Systems: Air, Liquid, Hybrid
Air‑assisted chilled‑water loops. Standard (S) and CHEMFLO® pumps deliver stable primary/secondary flows to chillers, CRAH/CRAC coils, and adiabatic or dry coolers. VFD‑based speed control and sensor feedback (implemented in the plant controls) help maintain the design ΔT while reducing throttling losses and pump energy.
Direct Liquid Cooling (DLC) & Rear‑Door Heat Exchangers (RDHx). For racks beyond conventional thermal densities, CHEMFLO® hydraulics combine with CDUs and plate heat exchangers to provide precise secondary‑loop flow at controlled temperatures. Low vibration, broad hydraulic coverage, and 316SS construction with seal options support service on deionized water and water–glycol commonly used in DLC and RDHx.
Immersion and liquid‑only architectures. Where alternative or dielectric fluids are specified, wet‑ends can be configured with seal/elastomer selections appropriate to the working fluid and temperature window. Integration with skid‑level filtration and heat‑recovery loops is handled by the system integrator; VFD operation enables close set‑point tracking as IT loads fluctuate. (Compatibility verified case‑by‑case.)
Redundancy by design. N+1 and 2N arrangements are achieved at system level using matched duty/standby sets, lead/lag logic, and isolation valves in the controls package/skid – aligning with Tier‑style uptime expectations.
