    Crypto Facility Mining | Design and Procurement

    Posted by Project Manager on 29th Nov 2021

    We have a mid size Crypto Mining Facility and wanted to up grade our ventilation due to excess heat and miner failures . Our procurement team contacted many ventilation distributors and found that they were not knowledgeable in Crypto Mining. We were given a referral to Factory Fans Direct and talked with Mike Miller VP Engineering and was impressed by their knowledge and experience in the Crypto mining industry. Mike and his team reviewed our specs on Static Pressure, Temperature and air flow and recommended a minor re-design and the required ventilation for our project. Our facility is now operating efficiently with no major issues. Factory Fans Direct was their for us throughout the entire process and continue to follow up. Highly Recommend. 5 Stars plus..
