EFFICIENT UV CURING: ENERGY COSTS… PRODUCTIVITY PAYS!

UV curing systems manufacturer GEW are launching a range of new UV systems designed to reduce running costs and extend production capabilities of both analogue and digital printing and coating machinery.

Focussing on the needs of web and sheet-fed media converters alike, GEW’s multisubstrate curing platforms enable the widest range of heat-sensitive materials to be processed without risking job scrappage due to heat damage. In addition, profitability is increased as significantly less electrical power is required to run the UV whilst energy is efficiently converted to UV, ensuring production output is maximised.

A priority for GEW has been to reduce its customers’ total cost of operation to a minimum by providing equipment that is inexpensive to maintain, as well as to run. Energy use is the main variable in the equation of cost reduction, however potential savings are easily negated by excessively priced consumable parts and time-consuming replacement procedures. GEW offers the lowest cost OEM consumable parts on the market and its quick-change lamps are replaced safely in under two minutes, with no specialist tools required.

A 40” sheet-fed press in the UK was recently upgraded with the latest energy-efficient UV systems in the interdeck and end of press positions, and now processes 9,500 sheets per hour with only 120 W/cm of UV power, using standard inks.

For low migration inks and specialised coatings, GEW has also released an economical inert atmosphere curing solution that uses around 35% less nitrogen gas than conventional solutions. One of these new systems was installed on a 2.3 metre wide converting line in Belgium last year, whilst an inline printing press in the USA was also equipped with a straight-through web path solution, enabling silicone release coatings to be produced without the chill rollers that are usually needed.

Longevity is also a key attribute of the new product line-up, which is designed to be old. A primary aim of GEW is to provide its customers with a future-proof investment that is easily maintained and fully supported throughout its life. As testimony to this, many of the first GEW systems ever sold are still working, and in 2011 the company’s 10,000th UV system produced was delivered to its first OEM customer.
