Humidity Solutions has designed, supplied, installed and commissioned a humidity control solution for digital print specialist VGL. The two ELMC10 electrode boiler humidifiers are maintaining the precise and stable humidity control required for a new HP 5600 digital printer at VGL's facility in Reading.

Established since 1976, VGL is a family-run company with a strong track record for investing in the latest print technologies to ensure it is offering its customers the best print quality and service. 'We recently upgraded to the HP 5600, which is considerably faster than the previous printer we were using,' VGL's Russell Fry explained. '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,' he added.

The two ELMC10 humidifiers are fitted with direct air ventilation units to distribute water vapour directly into the space, and are positioned at high level to ensure efficient distribution with no wetting of machinery. The units have been sized to allow for 12 air changes per hour and achieve a minimum of 50% RH and maximum of 70% RH (non-condensing) at 20-25°C.

In maintaining a stable humidity, the units are ensuring the printed products are of high quality while also eliminating static electricity.
