This was a very large data centre cooling project in which we have supplied 24 large V-blocks for over five years. It was subject to both performance and noise testing by a third party to ensure it met the site duty requirements and noise restrictions. All of our units were supplied with EC fans and bespoke temperature control panels enabling easy integration with their BMS systems on site. They offer massive power savings compared to the previous heat exchangers on site and cope with ease in the summer months. Large V-bank dry air coolers for a rooftop site in London. The first unit required witnessed performance and noise tests to be carried out before delivery.
