High-performance VPS,
dedicated servers
and colocation in Italy
on an IT platform fully immersed in a dielectric fluid.
KaralGreen is an Italian provider of cloud services, VPS, dedicated servers, and colocation, delivered on proprietary IT infrastructure installed in a dedicated area within a data center in Italy.
Our solutions and services are designed according to a simple and innovative principle: the cooling of all IT infrastructure components (compute servers, storage, or networking equipment) occurs directly and uniformly through total liquid immersion.
Real Efficiency Lower Costs Concrete Advantages
KaralGreen: a provider primarily serving SMEs, ISPs, and regional operators.
We collaborate with companies that require efficiency and reduced costs.
Economic savings are a direct consequence of using immersion cooling technology. Simple, clear, controlled, and predictable cost model.
Consistent performance
Real energy efficiency
Immediate and professional technical support
The concrete advantages of KaralGreen infrastructure.
Fewer breakdowns, less maintenance
The absence of fans, dust, and vibrations drastically reduces hardware failure points.
Support for extreme loads without throttling
CPU, storage, and networking operate at full load 24/7 without performance degradation.
Longer lifespan of electronic components
The elimination of thermal stress allows components to work better and longer.
Silent and clean operation
Zero dust on hardware. Components operate at full capacity in total silence.
Scalability and flexibility
Ideal for new installations, hardware expansions, or retrofitting existing infrastructure.

High-performance VPS
KaralGreen VPS are designed for real performance, not for overselling. VPS are located in physical nodes designed for high compute density.
Thanks to the immersion infrastructure, performance remains stable even under prolonged load, allowing us to offer more resources at the same cost compared to similar services operating with traditional cooling technology.
High-performance CPUs, with configurable number of cores, threads, and clock frequency upon request, without thermal limits
Dedicated RAM, high-performance frequency and transfer speeds
Ultra-fast storage, both HDD and NVMe SSD
High-bandwidth connectivity (up to 100Gbps)
Dedicated servers
Rent an entire KaralGreen server, co-located within our immersion tanks. Physical servers hosted on immersion infrastructure, ideal for intensive workloads and 24/7 operational continuity.
Maximum compute density without thermal limits
Latest generation CPUs with configurable number of cores, threads, and clock frequency upon request
High-performance RAM, memory capacity, frequency, and transfer speeds
Ultra-fast storage, both HDD and NVMe SSD
Protection from dust, vibrations, and overheating
Complete monitoring of your server in the tank: temperature, fluid, efficiency
High bandwidth: up to a maximum of 100Gbps per server
Shared tank colocation
If you desire greater autonomy, control, flexibility, scalability, and immediate access to immersion technology without investing in an entire tank, rent your dedicated space and immerse your IT equipment in one of our immersion tanks, designed to eliminate the limits of traditional colocation.
Rental of Rack Units (U) in single-phase immersion tanks
Each Rack Unit can contain one or more servers (nodes) and/or a number of network devices (switches/routers) approved for immersion
Redundant and configurable connectivity based on requirements
Real-time monitoring of temperature, fluid, and operating parameters
Reduction of carbon footprint
Maximum hardware protection: no dust, no vibrations, no overheating
Total scalability: ability to increase or reduce occupied space
Reduced cooling costs
Dedicated tank colocation
The perfect service if you wish to rent a reserved immersion tank, custom-designed to host your high-density IT infrastructure. Reserve an entire immersion tank exclusively within our premises and immerse your IT equipment. Ideal for companies requiring maximum autonomy, operational continuity, consistent performance, maximum flexibility, and independence in the management and design of their IT infrastructure.
Custom design for compute density, power, and cooling
Redundant, configurable, and customizable connectivity based on requirements
Advanced monitoring of temperature, fluid, operating parameters, and consumption
Dedicated environmental and operational efficiency reporting
TIER III certification to ensure continuity and security
Reduction of carbon footprint thanks to the drastic decrease in energy consumption
Maximum hardware protection: no dust, no vibrations, no overheating
Scalability: ability to increase or reduce the number of tanks based on requirements
All-in immersion solutions
for companies, ISPs, and operators
We replicate our complete immersion solution at your premises. Design and supply of tanks and cooling systems, transport, installation, startup, support, maintenance, and training. Perfect for significantly reducing the annual energy costs of your data center or private server room. It will allow you to achieve better performance for your IT infrastructure by operating in the tank at low temperatures (between 30°C and 40°C), as well as a longer lifespan for your hardware due to reduced thermal stress.
