Specification & Installation of Air Handling System to Holland Submarine gallery, RNSM

The National Museum of the Royal Navy has identified the need to improve the current air handling system in the environmentally-controlled gallery exhibiting the Holland I submarine. The original system has declined in efficiency and is now potentially detrimental to the preservation of the historic submarine, which is heavily dependent on maintaining the correct environmental conditions. Conservation of ferrous marine metals demands that a low relative humidity be maintained at a constant level, without fluctuations that can be very damaging to the historic fabric. Contractors are invited to specify and install a system to satisfy the target conditions required. Further details of this project are outlined in the brief attached below.
