One of the projects handled by Recard is an important installation at the Pratolungo Paper Mill in Pescia, in the province of Pistoia. The plant is part of the Industrie Celtex group that makes tissue and non-woven products for professional cleaning and hygiene. Celtex manages the entire production chain, its 4 plants covering the whole process from paper production right through to transformation. "The Pratolungo plant produces about 60 tonnes of paper for hygienic use every day, using both cellulose and recycled paper as a raw material. Its main output is paper of 15-18-20 grammes per square metre."
"Our work covered all the design and subsequent building of the whole system, including the installation of centrifugal pumps for conveying service liquids for the paste preparation area of the mill." A total of 16 open-impeller and closed-impeller pumps based on Robuschi technology, including 9 RACN models and 6 RCN - RCNS models of varying sizes of the PROMIX range, and 1 RNS pump of the PROCHEM range.
Recard designed the entire paper mill system. "In particular we simplified the plant engineering aspect, making it highly technological with solutions that guarantee savings both on installation and energy consumption." This technical innovation was further enhanced by the efficiency of Robuschi pumps. "We call this technology Easy Crescent", says Michelini. "It's a new way of conceiving the installation of a system for small and medium level production, from 50 to 80 tonnes of paper per day. It's much faster, easier and less expensive to build, with the added advantage that the tissue machine is also easier to run." Apart from the Pescia site, Recard has also installed the Easy Crescent concept in two other Italian plants and two abroad as well. The first was launched in Italy in 2002, and also used Robuschi pumps.
By applying this solution in the Pratolungo project, Recard was able to eliminate a vacuum pump that consumed about 200 kilowatts. "We managed to guarantee the same production volume, improving the life cycle of the machine and keeping the same quantity and characteristics of the paper but with a series of benefits: a reduction of the initial cost of the building work needed for installation, energy savings, and greater ease of use (in turn meaning lower operating costs and less maintenance). The system has been up and running for at least 4 years. It's efficient and the customer is fully satisfied."
