We at CyanX Ltd have been involved with press room humidification for many years and can advise in an unbiased way, which option would be most appropriate. To do this it is beneficial that we conduct a quick site visit to establish accurately the parameters of where it will be installed and exactly what the system is required to do. Identifying all the variables is essential to correctly specify the equipment to give the required performance, and we know it is all too easy to under specify to reduce selling price.

| High Pressure Systems |
We can offer this type of humidification for larger press rooms with a reasonably high roof space (8 metres and above). The system requires no compressed air to vaporise the water, depending instead on a considerably high water pressure (80-100 bar) forcing the water through microbore nozzles to create the aerosol water vapour. The pressure is generated from a high pressure pump which is activated from a controller taking a signal from one or more hygrostats set to required RH level.

| Low Pressure Systems |
This is more appropriate for small to medium press room requirements. It is more versatile in that less space is required to enable the water vapour to dissipate. The water is fed up to the small reservoir in the vaporisation head (normally at mains pressure of 3 bar) and from here the compressed air in the unique nozzle arrangement creates a vortex and vaporises the water at the point when air and water meet. The result is an extremely fine aerosol and dissipation is remarkably quick. This lends itself to applications where “spot” humidification can be applied to troublesome areas rather that humidifying the whole press room e.g. feeder / delivery of the press or troublesome folding equipment in the finishing area. |
