How Geoclima Chillers Can Save Energy and Money for Data Centers

Data centers are essential for storing and processing large amounts of data, but they also consume a lot of energy to keep their servers and equipment cool. Overheating can cause serious problems such as data loss, reduced performance, and increased costs.

That’s why data centers need reliable and efficient cooling systems that can provide constant and stable cooling 365 days per year. And that’s where Geoclima chillers come in.

Geoclima is a leading manufacturer of high-efficiency and customizable chillers that use green refrigerants and advanced technologies to reduce energy consumption and environmental impact.

Geoclima chillers are designed to meet the specific needs of data centers, which require:

  • compact size
  • low noise level
  • maximum customisation
  • and low maintenance.


We at Geoclima introduced the first HFO-1234ze chiller back in 2011. HFO-1234ze is the greenest refrigerant in the world with GWP levels lower than 1 (according to a 2015 IPCC study) and classified as A2L according to the ASHRAE 34 regulation.


One of Geoclima’s innovative products is our Circlemiser chiller, which features special cylindrical condensers that increase the heat exchange surface by 45%, resulting in higher efficiency and lower power consumption. Circlemiser records an increase in EER up to +9.5% (with one compressor units) and up to +15% (with multi-compressor units), with the highest achievable value of EER 4.35 (kW/kW).


Power failures can cause serious problems for data centers. That’s why FastStart system is the ideal solution for quick unit restart after power failure. And what’s more, FastStart system drives the unit straight back to the previous operational state, without any manual intervention or configuration. This way, the unit can resume its normal operation in a matter of seconds, minimizing downtime and maximizing efficiency.

Case studies

Geoclima chillers have been successfully installed in many data centers around the world, such as the Dart mega data centre in the UK, which achieved 50% energy savings thanks to Geoclima’s solution.
