Andritz has received an order from Winstone Pulp International Ltd. (WPI) to perform a comprehensive twin wire press retrofit at their Karioi pulp mill in New Zealand.

The Andritz approach is tailor-made to minimize the effort and time involved. Their current Andritz twin wire press with a working width of 2m has been in operation since the mill opened in 1978. To improve the machine's performance, reliability, and safety, Andritz will replace the machine's carbon steel frame with a stainless-steel frame and modernize further machine components. The retrofit will leave the machine foundations and connections basically untouched. All installed rolls and bearings will be reused, as well as the dewatering boards replaced by Andritz in 2019.

Winstone Pulp International Ltd., New Zealand is a privately owned subsidiary of the Oregon Group. The company comprises two operational sites, Karioi Pulp mill and Tangiwai Sawmill. The WPI wood processing operations produce a range of timber and pulp products derived from renewable plantations of Radiata pine for both New Zealand and international markets. The Karioi pulp mill produces 220,000 admt of high-yield BCTMP (Bleached Chemical Thermomechanical Pulp).
