Two-phase immersion liquid cooling cabinet
A self-contained phase-change cabinet for AI and supercomputing racks. Boiling does the heat transfer; gravity returns the fluid; no facility piping is required.
Built around the heat load, not around a rack size.
Built for high-heat workloads such as AI high-density computing and supercomputing, this all-in-one system uses phase-change boiling heat transfer. Cooling efficiency sits well above air cooling and conventional liquid cooling, which is what makes ultra-high-power operation stable.
The integrated design removes the need for complex infrastructure work, so deployment and maintenance stay simple. Overall power draw is exceptionally low: a data center running RH-ALIM-8 can reach a PUE of 1.02–1.05. A dielectric, flame-retardant coolant plus multiple protection mechanisms keep the cabinet silent, precise and safe in rooms of almost any size.
What the design buys you.
Phase-change boiling heat transfer
Latent heat of vaporisation outperforms single-phase convection — built for ultra-high-power computing.
Gravity-driven self-circulation
Cuts pump energy and lowers the total cooling power requirement.
Integrated design
Condensation, fluid replenishment and monitoring in one cabinet. Fast, simple deployment.
Uniform heat dissipation
Minimal chip-to-chip temperature variance, which prevents thermal throttling.
Dielectric, flame-retardant coolant
Non-flammable and insulating. No short circuit, no fire hazard.
Intelligent adaptive control
Multi-sensor feedback tunes cooling in real time.
Comprehensive protection
Low-fluid, leak and over-pressure safeguards for 24/7 operation.
