Helping to achieve top-quality digital printing at VGL is humidification equipment from Humidity Solutions.

Humidity Solutions has designed, supplied, installed and commissioned a humidity-control solution for digital-print specialist VGL. The two electrode boiler humidifiers maintain the precise and stable humidity control required for a new HP 5600 digital printer at VGL’s facility in Reading.

Russell Fry of VGL explains, ‘We recently upgraded to the HP 5600, which is considerably faster than the previous printer we were using. However, to maintain the required throughput reliably, we needed to ensure the relative humidity was stable.

‘We spoke to a number of humidity specialists, and it was clear that Humidity Solutions had the best understanding of what our business required, as well as the technical requirements for the printer.’

The humidifiers are fitted with direct air ventilation units to distribute water vapour directly into the space. They are positioned at high level to ensure efficient distribution without wetting machinery.

The units are sized to allow for 12 air changes an hour and achieve a minimum 50% RH and maximum of 70% (non condensing) at 20 to 25°C.
