Tongai Technology · QuadBox
80kW of liquid-cooled compute, anywhere.
A self-contained, IP67-rated compute node delivering four times the density of an air-cooled rack. Deploy on-premise or consume as a cloud GPU-as-a-Service — same node, same efficiency, two commercial models.
Thermal Alpha™ Technology
Direct liquid cooling, engineered for net-positive infrastructure.
Thermal Alpha™ removes heat at the chip with a closed-loop dielectric fluid, eliminating the fans, raised floors, and CRAC units that dominate air-cooled TCO. The recovered heat — 98% of input energy — is redirected to district heating, desalination, or greenhouse agriculture, turning a cost centre into a circular revenue stream.
- Closed-loop dielectric fluid — no evaporation, no water draw
- Chip-level heat removal — no hot-aisle containment needed
- Plug-and-play into any Tongai data centre stand
- Heat reuse partnerships with municipal and agricultural offtakers
Two ways to deploy
Premise-based. Or cloud. Same node.
QuadBox is one product with two commercial models — own it on your site, or consume it as a metered cloud service from a Tongai campus.
QuadBox On-Premise
Own and operate QuadBox nodes inside your facility or a Tongai data centre. Full capital control, on-site heat reuse, and zero dependency on a third-party cloud.
- CapEx ownership with 25-year asset life
- Direct liquid cooling — no raised-floor CRAC retrofit
- Recovered heat for district heating, desalination, or greenhouses
- Managed-service SLA option via Tongai Technology
QuadBox GPU-as-a-Service
Consume QuadBox capacity on-demand from a Tongai-operated campus. Per-hour GPU billing, no capital outlay, and the same liquid-cooled efficiency as the on-premise node.
- Per-hour H100 / A100 billing
- Burst from 1 GPU to full 80kW node
- Tongai Connect OPGW backhaul included
- Carbon-attributable compute — PUE < 1.05
