Mechanical Adaptation Works & Associated Works for Spirit Store

National Museums' Liverpool, Spirit store, situated in the basement of World Museum, William Brown Street, is used for the storage of specimens preserved in ethanol. The room has recently been downgraded from an ATEX rated room (see DSEAR Technical Note v5) and the monitoring system upgraded with new ethanol sensors and a control system which currently provides monitoring only, via the Museums site wide Eltek system. The spirit store has a supply grille which is part of the general ventilation system and a failed close controlled Denco air conditioning unit (in the adjacent library) to control temperature and humidity. The Denco unit, its refrigerant heat pump system and associated ductwork will be stripped out. In its place, will be installed an extract run, standby fans on the roof and a new set of controls to link into the ethanol sensors. The existing ATEX rated lighting will be removed and replaced with standard LED fittings. Fire stopping, fire door repairs and associated works including decoration will be effectuated as specified in the tender documents.
