FAQs

Common questions about liquid cooling, RDHx, and CDU systems.

Is liquid cooling safe for my data center?

Apex Thermal systems use industry-standard materials, leak detection, and isolation designs. The secondary loop architecture keeps facility water separate from IT coolant.

Can RDHx be retrofitted to existing racks?

Yes. The ATR-60 and ATR-100 are designed to replace standard rear doors on most 42U–52U cabinets with minimal modification.

What water quality is required?

CDUs accept standard facility chilled water on the primary side and circulate conditioned inhibited water or dielectric fluid on the secondary side.

What maintenance is required?

RDHx doors have no moving parts and require periodic visual inspection. CDUs include redundant pumps and filters with hot-swap service procedures.
