Watch as we install a 336U high-density ICEraQ® immersion cooling system at Zelendata Centar, making it Serbia’s first green data center and a powerful AI computing solution—in only three days.
The Zelendata Centar Features:
- Two ICEraQ Quad Systems Totaling 200 kW
- 336U of High-Density Compute with Supermicro Servers
- 90% Reduction in Cooling Power & 40% Less Total Energy Consumption
- Wind as Its Primary Power Source
- Zero Water Waste
- Zero Installation Waste
And, this is just the beginning. They have plans for a total of eight ICEraQ Quad systems totaling 800 kW — that’s equivalent to over 64 standard, air-cooled racks!

Some Very Green Facts About the New Zelendata Centar
• 336U of high-density compute, built to support Artificial Intelligence processing demands
• 90% reduction in cooling system electrical consumption
• 40% reduction in total energy consumption
• Main source of electrical power: MK Fintel Winds’ Košava Wind Farm in Izbiste
• Zero water waste with a closed-loop hybrid dry cooling tower
• All internal fans were removed from the Supermicro servers as part of our conversion to immersion process before being immersed in
our ElectroSafe® coolant
• Zero installation waste – recyclable materials only
• Only “spare and repair” parts remain at the site
• The data center was designed and built to achieve the lowest possible carbon footprint
The Installation
You’ll notice there are no raised floors. We worked straight on polished concrete.
Even the Coolant Distribution Units (CDU) are being placed straight on the concrete floor.
The installation of two ICEraQ™ Quads begins by placing secondary containment decks on the concrete floor. Notice, we hand lift the racks and carry them in place.
The actual installation crew included three technicians. The rest of the people are running power, water and prepping the network backbone.
The installation is very straight-forward and clean – typical for GRC.
You will see we begin connecting some hoses and manifolds from the racks to the CDU’s and start filling the ICEraQ’s with coolant. Each ICEraQ takes about 20 minutes to completely fill.
Maintenance training takes place both during the installation process and after it’s completed.
By the way, it was really cold in there – about 12oF/-11.1oC
As you’d imagine, there were quite a few observers on hand to watch this green data center come to life. Even with a lot of activity in the work area, we’re already installing and filling the four racks of the second ICEraQ Quad.
By now we’ve connected all the racks to a control computer, started monitoring CDU functions, checked performance, and made final adjustments to each rack. We’ll run the system for a couple of days to make sure everything is completely sealed and in perfect working order.
The final image shows the two ICEraQ Quads with an interface to monitor and control all system functions from a single location. The setup also includes a hoist to facilitate lifting the Supermicro servers in and out of the racks.
Zelendata Centar will soon expand their HPC capacity by adding six more ICEraQ quads, further strengthening their position as the most environmentally-responsible colocation data center in Serbia.
Rapid Deployment
Only three days were required to completely prep, install, and test two ICEraQ Quads — turning four walls and a bare concrete floor into an up and ready-to-run 200 kW capable data center.
Conversely, a typical comparable air-cooled data center would take closer to 12 months.
