Rizzi Energy was founded in 1938 to design and manufacture energy saving systems through heat recovery and fuel economizers for preheating feed water of steam generators. From thirties until now, Rizzi saw thermal power stations birth and fast growing, supertanker ships reach 500.000 tons, chemical, petrochemical and oil refineries beeing built everywhere.

Those "revolutions" helped us to set up company facilities fully provided with advanced engineering tools, a very efficient network of computers working with proprietary software for research and calculation in a whole surface of 30.000 m2 of 6.000 m2 covered area. The state of the art energy saving technology with competitive quotations. R&W proudly represents Rizzi Energy products and systems in Brazil.
Systems for hydrocarbon and petrochemical industry

In order to work and produce in a correct and competitive way every chemical and petrochemical complex, every oil refinery requires a large variety of plants and systems for heat transfer, as well as specialized energy saving systems. The improvement and revamping of existing plants, in addiction to process optimization, is also a vital need. Rizzi offers skillfull and up-to-dated design and engineering services for all equipments and plants indicated in the TABLE BELLOW.

Rizzi can also manage a complete system for energy saving or heat transfer, starting from feasibility studies up to detailed engineering, calculations, development of drawings, quality assurance service, assembling control and handling of deliveries.

Systems for Thermal Power Stations
Big power plants require big results from energy saving plants, results that only an experience consolidated in time, through thousands of realized plants, can guarantee.

The experience reached in more than 60 years of activity in energy saving enable us to design and manufacture with up-to-dated and highly reliable features all the equipments quoted in our production range of the TABLE. Rizzi is also able to carry out a whole specific system of energy saving or heat transfer starting from feasibility studies up to the handling of deliveries, including also detailed engineering, calculations, development of drawings, fabrication, quality assurance and supervision of erection.
Systems for Marine Industry
In order to navigate in conditions of perfect efficiency, security and to gain maximal profits, each type of ship requires also a variety of plants and systems for the heat transfer as well as specific systems for energy saving. Moreover, the improvement and revamping of existing plants in addition to process optimization are of vital need.

As a result of our vast experience and efficiency we are able to offer engineering and design services of high quality and up-to-dated technology for all types of equipments indicated in the TABLE. Rizzi is able to manage a complete specific system of energy saving or heat transfer beginning from feseability studies up to the supervision of the assembling and the handling of deliveries, including also the detailed design, engineering, development of drawings and quality assurance.
Systems for Solar Energy
Rizzi provides Solutions for:
• Solar thermal panel for hot water production
• Solar thermal panel for hot air production
• Sea water desalting systems
The experience of Rizzi Energy in the field of solar energy goes back to the early '70s. In that period we realized the first solar steam generator in collaboration with Prof. Francia, the most known Italian researcher in the solar sector. Thanks to several experimental tests our company developped special surfaces giving high efficiency absorbtion rates of solar radiation. Today our technology is leader in high efficiency absorbing surfaces.
