HVAC plant renewal, Holland Submarine building, RNSM

The purpose of this ITT is to commission the supply and installation of 2no. desiccant dehumidifiers and 2no. heat pumps to replace failing units servicing the Holland Submarine gallery at the Royal Navy Submarine Museum in Gosport, Hampshire. The existing units must be disposed of and the new units must fit into existing plant room, maintaining a max.35% relative humidity within the gallery space. The preservation of the Holland submarine relies on this low humidity and is currently at risk due to failing plant.
