Our services

Three trades, one point of contact

The same network links your offices, your servers and our tanks. You talk directly to the team that runs it.

01 — Connectivity

Fibre and static IPs

Fibre connections for businesses, buildings and property managers, with static public IP addresses from our own prefixes.

  • Professional connections on any technology, anywhere in Belgium
  • Static IPs assigned by Allegria Solutions
  • BNIX access through the route servers

02 — Hosting

Cloud and hosting in Belgium

Virtual machines, website hosting and backups on infrastructure run by a Belgian company.

  • Data hosted in Belgium
  • Directly connected to the Allegria Solutions network
  • Private AI: locally hosted LLMs
  • A direct technical contact

03 — Immersion

Immersion computing and heat reuse

Servers, GPUs and blockchain servers submerged in a dielectric fluid: their heat goes into space heating and hot water instead of being vented outside.

  • Colocation in our tanks in Brussels and Anderlecht
  • Your local data centre, delivered end to end
  • Redundancy through the decentralised network
  • Heat connection coordinated with your teams

From network to heat

Every kilowatt works twice

A server turns all the electricity it uses into heat. In an Allegria Solutions tank, that heat is recovered instead of being thrown away.

  1. Connect

    Allegria Solutions fibre links the site to our network and to BNIX.

  2. Compute

    Machines run submerged in a dielectric fluid, with no fans and in silence.

  3. Recover

    A heat exchanger moves heat from the fluid into the building's water circuit.

  4. Heat

    Radiators and the hot water cylinder use that heat all year round.

A 10 kW tank heating a Brussels home

Our first tank hosts an AI server and servers, including blockchain servers. All of its heat is recovered for the space heating and hot water of the house it sits in.

A second 10 kW tank is ready in Anderlecht, with its heat also fully reused. There is still room in both tanks and in our rack at the data centre.

Private AI

Your AI, without your data leaving the data centre

Allegria Solutions hosts AI servers running large language models (LLMs) locally, today in our Brussels tank and, over time, in several tanks across the network. You use them from home or from your offices, over our network.

  • LLMs hosted in Belgium, on our own AI servers
  • Access from home or your offices, over the Allegria Solutions network
  • No data sent to any external AI service
