Gratte Brothers is a third-generation family business , established in 1946 that has been offering combined M & E solutions for over 35 years ; its first data centre project dates back to 1995 . During the last six years the company has consistently delivered 30 megawatts of IT power to the mission critical construction market every year .

Resilient

“ We offer specialist knowledge when it comes to resilient engineering services ” assures Gratte ’ s Engineering Director , Remi Suzan . “ We ’ ve worked with DC supply chains for decades , and have good relationships with our manufacturers and specialist subcontractors . Our contract engineers , site managers , and in-house commissioning teams don ’ t just understand how they work , but ‘ why ’ they need to work that way , and they bring that deep knowledge to every project .”

Modular

Gratte Brothers has worked with Ark for over a decade ; an integral part of its partner ecosystem developing modular DC solutions with low energy consumption at their core . “ Together with Ark ’ s other partner contractors , we worked on developing a modular energy centre that could be associated with the prefabricated data centres that could then be deployed either as a single unit or as multiple units , depending on what Ark needed at the time ,” confirms Suzan . “ The energy centres containing the UPSs and LV panels were all provided with a cooling system designed on external fresh air . It was calculated that for 98 % of the year it could operate without mechanical cooling which was only required in exceptional circumstances at high-peak summer periods .”

Sustainable

“ Ark are way ahead of the game when it comes to sustainability ,” reckons Suzan . “ Their approach is more than just a green message on their website ; they really mean it . Now that we can use adiabatic fresh air cooling systems for IT equipment with heat recovery in all of our air solutions , allied with the use of photovoltaic panels and LED lighting , energy efficiency has greatly improved .”
