Marsh System has proudly been involved with the British Library from its early construction days. Initially we were tasked with the developement of the Trend control

strategy for the operation of the installed complex wet system. This was designed and fully developed on site and is still operational, largely unmodified today. Although our client has changed several times over the years, we have always been retained at the Library to maintain the installed BMS and environmental controls. In addition to the maintenance of the BMS, we also provide as part of our service agreement full technical support, Help Desk assistance and certified off-site calibration of critical sensors, together with our ongoing recommendations for system enhancements and upgrades.
