Fujifilm has installed a Condair JetSpray humidification system at its Imaging and Innovation Centre in Bedford to maintain optimum atmospheric conditions for paper storage and printing.
The JetSpray has been installed to control the RH (relative humidity) in Fujifilm’s demonstration area, which incorporates the latest Jet Press 720s.
The humidifier consists of a control panel feeding compressed air and water to rows of self-cleaning spray nozzles mounted in the area to be humidified. The compressed air atomises the water as it is released from the nozzle, creating a very fine aerosol that rapidly evaporates. The nozzle design ensures that water can only be introduced when compressed air is flowing, guaranteeing drip-free humidification. The system has a fully modulating output and offers very close humidity control at ±2%RH. It can run on mains, demineralised or softened water.
‘Humidity control is important for paper handling consistency when running lighter weight stock on the Jet Press 720S in both the feeder and jetting area,’ explained Steve Freeman, Jet Press solutions manager at Fujifilm. ‘We aim to maintain an RH of between 40% and 60%. Below this could potentially cause an increase in paper handling issues on light weight paper.
‘Once the humidifier was up and running correctly, it has performed well,’ he added. ‘It now easily and quickly gets the room up to the required RH and maintains this after start-up.’
