Tank Colocation Rack Unit means installing your hardware (servers, switches, routers) in Rack Units inside immersion tanks filled with dielectric fluid. Unlike traditional Colocation where servers are air-cooled, immersion completely eliminates dust, vibrations, and thermal stress. Each Rack Unit houses your equipment approved for immersion. You maintain ownership of the hardware, while KaralGreen manages the physical infrastructure (tank, fluid, monitoring, maintenance). Energy consumption is measured and billed based on actual usage, ensuring maximum transparency. You achieve superior energy efficiency (PUE 1.03) and total hardware protection without investing in an entire dedicated tank.

The best Colocation Rack Unit offers in Italy combine energy efficiency, hardware protection, and local technical support. KaralGreen is the first Italian operator specializing in immersion Colocation in data centers in Italy. We offer Rack Units in single-phase immersion tanks with a PUE of 1.03 (vs 1.5-2.0 for traditional Colocation), real-time temperature and fluid monitoring, and configurable redundant connectivity. Your hardware is protected from dust, vibrations, and overheating. Management and maintenance are handled by our team, with transparent energy billing based on actual consumption. Total scalability: increase or reduce occupied space without constraints. Direct technical support in Italian, not from foreign call centers.

Liquid cooling in Colocation offers operational and economic advantages impossible with air cooling. Zero dust means no component degradation, zero vibrations mean superior hardware longevity, and zero thermal stress means constant 100% performance. Energy efficiency is drastically higher: PUE 1.03 vs 1.5-2.0 for air Colocation, with savings of up to 60% on consumption. No expensive HVAC systems to maintain, no limits on compute density. The dielectric fluid dissipates heat uniformly, eliminating hotspots and throttling. Real-time temperature and fluid monitoring ensures preventive interventions. Immediate scalability without thermal constraints: add Rack Units without worrying about cooling capacity.

KaralGreen is the first Italian operator specializing in Tank Immersion Colocation Rack Units with full technical support. Our team manages installation, 24/7 monitoring, routine and extraordinary maintenance, and replacement of failed components. Direct technical support in Italian from specialized personnel who know the immersion infrastructure in detail. Unlike international providers with multilingual call centers, we guarantee rapid and competent assistance on all operational aspects: from dielectric fluid monitoring to thermal management, from connectivity to hardware troubleshooting. Tank interventions are performed exclusively by our personnel certified to operate safely with dielectric fluids.

KaralGreen operates data centers with immersion technology in Italy, offering Colocation Rack Units, dedicated servers, and dedicated tanks. Our infrastructure uses single-phase immersion in dielectric fluid, with a PUE of 1.03 and real-time monitoring. With servers physically located in Italy, you get minimal latency, guaranteed GDPR compliance, Italian billing, and local technical support. Immersion eliminates the limits of traditional Colocation: no thermal constraints on compute density, no hidden HVAC costs, and total hardware protection. Ideal for companies seeking superior energy efficiency while keeping their hardware on Italian territory with full control and immediate scalability.

For Italian companies, Tank Colocation Rack Units offer strategic advantages: PUE 1.03 energy efficiency with savings of up to 60% on consumption, no initial investment in proprietary infrastructure, and immediate scalability without thermal constraints. Hardware is protected from dust, vibrations, and thermal stress, ensuring superior longevity. Operational management is entrusted to KaralGreen: maintenance, 24/7 monitoring, and component replacement. Data centers in Italy mean reduced latency, native GDPR compliance, and direct technical support in Italian. Transparent energy billing based on actual usage: you only pay for the energy actually consumed. Ideal for SMEs, system integrators, and providers who want to eliminate their own data center costs while maintaining control over their hardware.
