POZZI: a long history of expertise and professional service towards innovative and sustainable technologies.

POZZI LEOPOLDO has been manufacturing textile machinery since 1885. Well aware of nowadays’ challenges, with a vision of progress that integrates immediate and longer-term objectives, POZZI has been among the first machine builders to work towards sustainability, designing and constructing energy-saving products. The solutions range from dyeing machines to chemical dispensing systems, from fixing and conditioning machinery to heat recovery units, with RCR being the first rotating energy optimizer ever built to successfully recover heat from heavily polluted water effluents, especially designed for the textile industry, but practically used anywhere there is a discharge of dirty hot water and the will to recover otherwise wasted heat. By patenting the RCR Pozzi has reached far beyond the textile field, so much so that in 2016 the European Union funded R&D of the newer RHeX model of rotating heat exchanger under Grant Agreement n. 727930 of the Horizon 2020 "LowUP" project. Its major benefits are: fouling-proof, pressure resistant up to 5 bar thanks to new design and robotized welding procedure, added pumping action for smooth treatment of viscous effluents, modular assembling of rotor disks (easy substitution in case of damage), overall maintenance-free, increased efficiency even with fluids at lower enthalpy. Fields of applications: textile, food and beverage, tanneries, industrial laundries, tank cleaning, sewage treatment, semi-residential facilities like hospitals, hotels, large buildings and wherever large quantities of very dirty effluents are discharged.

The natural evolution of the RCR design: how to turn an acclaimed winner into an even better performer

The RHeX enhanced rotating heat recovery unit is a recent development of the original RCR design; its main purpose as an exchanger is to be able to treat a very polluted stream of effluents minimising the effects of fouling and clogging, which standard heat exchangers are normally subject to. The exchanger is basically made to treat two streams of counter current fluids: • A primary fluid, flowing outside the rotor of the exchanger inside the trough. This fluid will be subject to a very low-pressure loss. In fact, gravity will be the sole force used to push it through the exchanger even in case it is highly polluted with mechanical impurities. • A secondary fluid, flowing inside the rotor, counter current to the primary one, will always be clean and free from mechanical impurities, The patented technology that lies behind the RHeX design is based on the idea that the whole exchanging surface is constantly kept in rotation inducing a centrifugal action that helps keeping the exchanger clean. In addition to its anti–fouling action, the shape of the rotating disks, which are the actual exchanging surface of the machine, allows for a positive pushing action exerted on the primary fluid towards the outlet port of the exchanger, reducing the pressure loss on this circuit. Furthermore, in the new RHeX design each disk composing the rotor is no longer welded to the next one but simply mounted on a central shaft with interposition of a gasket, allowing substitution in case of damage. It is overall a self-standing, robust and compact ancillary unit improving the efficiency of the machine or system to which it is connected.
