POZZI’s advanced system for recovering heat from waste effluents

Pozzi-pic-2Textile wet processing is one of the main sources of pollution in many developing countries. The typical processes are high energy and water consuming with enormous discharge of hot polluted wastewater.

Textile businesses can take a lead role by taking steps that help save money, improve productivity, protect the environment and secure the nation’s energy requirement. At a time when “going green” and “sustainability” are the key words of cleaner production as an integrated approach to contemporary textile manufacturing requirements, POZZI LEOPOLDO of Italy, producing textile machinery since 1885, has been among the first machine manufacturers to work towards sustainability, designing and patenting energy-saving products certified by independent national boards.

To allow the shift to a safe and sustainable low-carbon and low-input economy, the wide variety of POZZI LEOPOLDO products ranges from dyeing machines to chemical dispensing systems and from fixing and conditioning machinery to heat recovery units. POZZI’s RCR is the first rotating heat exchanger ever built to successfully recover heat from heavily polluted water effluents.

Pozzi-pic-1A rotating shaft with stainless steel disks (the heat exchanging surfaces) creates the necessary turbulence to keep the pollutants of hot discharged effluent water from sticking to the exchanger surface. The resulting unit is a self-cleaning and maintenance-free accessory, making RCR a great tool of sustainable technology and a fantastic way to recover energy, as well as money, with a guaranteed high efficiency, contrary to what happens with all other types of heat exchanger, such as shell-and-tube or plate exchangers, which are day after day strongly affected by the fouling effect.

For doubling the efficiency of a standard shell-and-tube exchanger, RCR can be easily applied to both continuous and discontinuous processes, always guaranteeing pay-back of your investment in a very short time.

RCR was patented and certified by various independent energy organizations in Italy (ENEA), France (Centre Textile de Mulhouse) and England (British Standard Best Practices) for its exceptional energy-saving performance and for its working reliability.

A computer-generated algorithm quickly calculates your potential energy recovery and your payback time, translating into useful numbers the efficiency of POZZI RCR and the significant amount of saved money that could possibly be converted into other investments to improve your factory working.
