We keep our winter temperature in 90% of our 2 buildings at between 15 C and 17C all the time. We need humidifiers in the winter but from mid May to September nothing. You may find you need humidification rather the dehumidification. We are in a new built general unit. We try to keep the temperature as low as possible. We have 3 humidifiers for 2 large units, and can keep the RH to between 45% and 55% for more than 90% of the time. We have used dehumidifiers about twice in the wet autumn or wet spring. We normally need some humidification. We use a Hanwell radio telemetry monitoring system which records every 15mins so you get a very accurate picture of what is going on night and day. If you can keep the temperatures very low i.e. 15 C or 16 C (National Trust - Conservation heating style ) you can achieve a much better control The key in my view is to get the right type of Continuous monitoring, Hanwell radio telemetry system or Tiny tag (George Monger uses Tiny tag they are cheaper) or some other system - Preservation equipment Ltd or Conservation by Design sells this type of equipment I am able to download in a CSV format & send you some of our data for you to look at if you like - they can be opened in an excel spreadsheet Mary J Mary Macqueen ACR Museums & Heritage Officer: Conservation & Collections Wakefield Council Sport & Culture WMDC Central Museum Store Milner Way OSSETT WF5 9JE [log in to unmask]<mailto:[log in to unmask]> phone01924 262717 mobile 07870859480 For further Information please visit: www.experiencewakefield.co.uk<http://www.experiencewakefield.co.uk/> www.wakefield.gov.uk<http://www.wakefield.gov.uk/> ________________________________ The WMDC Disclaimer can be found at: http://www.wakefield.gov.uk/SiteInformation/E-MailDisclaimer/default.htm This message has been scanned for malware by SurfControl plc. www.surfcontrol.com The SHCG list is provided for members of Social History Curators Group to discuss subjects relevant to social history in museums.
