We use green enery - 97% of the total electricity consumption that our facilities use comes from our Hanwah solar panels and for ventilation we use natural air circulation by keeping each pod (28mining rigs in a room) on a different pressure level. For maintenance we have a 3-shifts system of surveillance in order to lower our response time in case of a problem or emergency. All maintenance of the equipement is done by a third party (authorized services such as http://www.tehnikom.info/).

Hope this answers your question and if you have any more feel free to ask. Cheers!
