Reducing PUE from 1.8 (typical air-cooled) to < 1.1 (liquid-cooled, optimised) reduces annual cooling energy by 70%+. Over 10-year facility lifespan, energy savings compound to £5–15 million for 10 MW facilities.
Surplus thermal energy recovered from computing, storage, or industrial processes is redirected to facility heating, domestic hot water, or district heating networks. Waste heat recovery reduces auxiliary heating demand by 15–55%.
GPU clusters experiencing ±10°C temperature swings degrade performance and shorten hardware lifespan. Liquid cooling delivering ±1–2°C stability improves compute throughput by 5–10% and extends hardware life by 2–3 years.
Thermal systems cannot be designed in isolation. NOVTRIQ integrates all disciplines from initial planning, ensuring thermal design informs power architecture, infrastructure footprint, and capex efficiency.
Liquid collets mounted directly on GPU dies, eliminating thermal interface materials and intermediate cooling stages. Heat transfer coefficient of 10,000–20,000 W/m²·K versus 100–500 W/m²·K for air cooling. Junction temperature reduced to 45–55°C with ±1°C precision through PID controllers and chiller management.
Passive or active heat exchanger installed in server rack rear door, capturing hot exhaust air and exchanging heat with facility coolant loop. Captures 40–60% of total thermal load with minimal pressure drop. Ideal for retrofit projects where full liquid cooling infrastructure is not feasible.
Server components submerged in dielectric cooling fluid (perfluorocarbon or synthetic hydrocarbons). Heat transfer coefficient of 1,000–5,000 W/m²·K. Fluid circulates through facility chiller and returns to immersion tank. Non-conductive, non-flammable options available.
Components submerged in dielectric fluid with boiling point 45–60°C. Heat boils fluid; vapour rises to condenser coil, releasing latent heat; condensed liquid returns via gravity. Highest heat transfer coefficient among liquid cooling technologies: 10,000–50,000 W/m²·K. Enables 5–6x compute density increase.
Modern infrastructure generates substantial surplus thermal energy. NOVTRIQ designs waste heat recovery systems that transform this liability into a resource, supporting decarbonisation targets and reducing operational costs.
Recovered heat preheats supply air for building HVAC or supplies radiant heating panels. Typical savings: 20–40% heating energy reduction in temperate climates (UK, northern EU).
Heat exchangers supply 40–50°C water for occupant facilities. Combined with facility heating, DHW applications capture 30–50% of recovered thermal energy.
Surplus heat exported to adjacent buildings or district heating schemes. Regulated in UK via District Heating Policy Framework; EU-wide support through EPBD 2021/1952.
Recovered heat integrated with industrial processes (steam generation, preheating input materials). Sector-specific; typical savings 15–30% process energy.
Facility heating reduction: 20–55%. Carbon footprint reduction: 15–30% facility-level. Heat rejection to environment reduced by 50–80%. Payback period: 3–5 years through energy savings; improved to 2–3 years with carbon credit monetisation.
Power Usage Effectiveness (PUE) = Total Facility Power / IT Equipment Power. NOVTRIQ targets PUE < 1.1 for liquid-cooled deployments, reflecting industry-leading energy efficiency.
| Cooling Technology | Typical PUE Range |
|---|---|
| Air-cooled baseline | 1.6–2.0 |
| Optimised air cooling | 1.3–1.5 |
| Liquid cooling (RDHx retrofit) | 1.2–1.4 |
| Single-phase immersion | 1.15–1.25 |
| Two-phase immersion | 1.0–1.15 |
| Two-phase + waste heat recovery | < 1.0 |
Designs comply with UK Building Regulations Part L, EU EPBD 2021/1952 NZEB standards, and ASHRAE 90.1 energy performance targets.
Whether you need direct-to-chip cooling for GPU clusters, immersion cooling for edge deployments, or waste heat recovery for industrial facilities—NOVTRIQ delivers thermal engineering mastery across all sectors and both UK and EU jurisdictions.
