Precision window actuators from SE Controls are being used as part of an energy efficient natural ventilation system at the Sheffield University’s Nuclear Advanced Manufacturing Research Centre (NAMRC) in Rotherham, to help maintain a comfortable environment for researchers and staff.
To provide the high degree of control required, SE Controls, supplied, installed and commissioned a range of chain actuators, which are linked to the NAMRC building management system and are used to control the operation of the high and low level vents.
Twenty TGCO 24 15 actuators with a 350mm stroke length were installed on the building’s high level exhaust vents, while the need to protect against finger entrapment on the low level louvres prompted the selection of eighteen SE Controls’ TGCO 24 20 ‘Easi-Drive’ compact actuators each with 160mm stroke length.
SE Controls’ Project Manager, Darren Wainwright, explained, “It is absolutely vital that the natural ventilation strategy and system perform as designed to allow the right amount of fresh air to enter the building while ensuring that heat energy is not lost unnecessarily during the process. By using precision actuators to provide incremental operation of the system’s vents and louvres, it helps ensure that required performance is within the specified design parameters.”
