COMPACT PRESS™ wash press: Maximized efficiency, compact design
The exceptional performance of the ANDRITZ COMPACT PRESS makes it an excellent choice for individual washing plants as well as entire fiberlines. Over its history, nearly 170 COMPACT PRESS washers have been sold to customers around the world, and since 2019, it has been an integral part of the ANDRITZ washing portfolio.
The COMPACT PRESS has a small footprint and a compact design, making it the perfect retrofit washer for all sizes and capacities of pulp mills, even those with very limited space in the fiberline. It is also suitable for full fiberlines, where it provides superior wash press performance to meet the most demanding customer requirements. The presses are available in nine different sizes, starting from a capacity of 400 t/d up to 6,000 t/d, and are designed to suit all pulping processes, including kraft, semi-chemical, and mechanical pulp. The latest development at ANDRITZ has seen the introduction of a dewatering press based on the same technology for the dewatering of mechanical pulp.
Proven advantages
The presses have a number of proven advantages that set them apart from other wash presses, including a highly efficient process with high discharge consistency, tough, durable components, and easy maintenance.
The COMPACT PRESS has been developed to maximize dilution-extraction, displacement and final pressing during the wash cycle. Feeding the COMPACT PRESS at higher consistencies and making greater use of the drum surface provides superior washing capability within a small footprint, making it the best wash press on the market.
Unique concept
The COMPACT PRESS is built around the UniWash™ process concept. This concept has three main features: UniFeed™ pulp distribution system; high pulp consistency in the wash zone; and low wash liquor velocity. The COMPACT PRESS is built to last, so it requires little maintenance - and when it does need to be serviced, it has several easy-maintenance features that make the task easy.
