How the “Vactis Method” works to create a personalised and tailor-made solution for your company.

For Vactis, each new project is a way of putting ourselves to the test; this is why we have outlined and tested a modus operandi that allows us to be true partners for those who decide to turn to us. We create tailor-made, efficient solutions for every need.


Our approach to a new project is divided into 4 main phases:


  1. The energy diagnosis, focused on reducing costs and improving performance. This first aspect is fundamental in order to identify the margins of improvement achievable with our interventions.


  1. The data analysis and solution study is the central moment of the whole project; in this phase we analyse the data collected during the diagnosis, in order to study a solution based on the needs of our partner, taking into account all the relevant variables. In this phase we calculate the PUE (Power Usage Effectiveness) and check the electricity consumption in its current state, before our intervention.


  1. We propose the solution based on free cooling technology, taking into account how our partner’s needs may change over time, always guaranteeing a reduction in costs and an improvement in energy efficiency.


4. We proceed with the realisation of the customised, tailor-made project. Thanks to the valuable work of our highly qualified team, we produce and customise solutions that, in accordance with the partner’s technical specifications, require low maintenance and improve performance in terms of both costs and energy efficiency.

The results obtained thanks to our working method.

We are putting under the magnifying glass one of our works, carried out at the Open Fiber PoP in L’Aquila. It was the installation of the free cooling technology system inside the PoP.


In this case too, we meticulously followed the 4 main steps and before proceeding, we carried out a climatic analysis of the external temperature data of the city of L’Aquila, ranging from + 5°C to 25°C.

Next, we checked the number of hours in which it was possible to use free cooling, i.e. the hours in which the external temperature is between +5° and +25°C.


And finally, we calculated the power that can be subtracted, using the hours of operation resulting from the previous analyses, with the installation of the free cooling system.


Our systems resulted in a saving of 46,817 kWhel, which in economic terms is equivalent to € 8,427 less per year.


A difference of more than € 8,000 per year, therefore, which, considering an investment of about € 22,266.20 allows a simple return in about 2.6 years and a PRA of 3 years.


In addition to this, there are also savings in subsequent years compared to what the company would have had to continue paying under the previous system.


The numbers explain more than any words how direct free cooling is now the most economically and environmentally advantageous system for cooling TLC rooms and data centres.
