We make power, we produce heat, we work for the future. A leading company which is recognisable for its investment into research and development and its capacity to transfer knowhow.

The company was established in 1958 principally in the manufacture of industrial steam boilers. Since then, the company has further utilised its knowledge and skills into the design and production of domestic and commercial hot water boilers. Energy saving and environmental protection are fundamental to the basis of the boiler design and research. C CALDAE presently holds a leading position in the heating industry as a result of its ongoing research activity and development of highly reliable and advanced technology boilers.

Expertise and updated knowledge are key elements to successfully participate in today s market

Training Expertise and updated knowledge are key elements to successfully participate in today s market. These are the skills that the C Caldaie Training Center is designed to promote to its customers. The training program includes the opportunity to demonstrate the functioning of domestic boilers, heat meters, large condensing boilers, solar systems and industrial steam boilers. By request, subject specific seminars can be accommodated, such as industrial plant design and installation according to the PED norms, centralised boiler plant with satellite metering stations, installation of three star boilers or condensing boilers in cascade arrangement, application of hydrogen fuel systems for cogeneration on domestic applications. During the training, visits are made to the production department, highlighting technical details that are not always apparent in the boilers. These can be discovered together with the QC material approvals and tests that every boiler undertakes during the production process.

C CALDAE has a wide product range to suit most heating applications

Production C CALDAE produces boilers for the Domestic Market from 2335 kw, Commercial Boilers from 22 3,5 kw, and ndustrial Boilers for Pressurised Hot Water Systems. Within the above markets, C CALDAE has acquired an international reputation for products of the highest quality.

The favourite solution for building energy classification

MULTOMOUS SYSTEM SOL solar collector Puffer Monolite condensing boiler C Caldaie Metering stations This system combines the highest energy efficiency of the building With the full independence of each apartment: Low consumption, with no maintenance, can be integrated with renewable and environmentally friendly energy sources; this is the favourite solution for building energy classification.

We manufacture innovative customised designs to meet our customer s requirements

Boiler Houses Complete and compact packages for customised boiler plant requirements. We specialise in the production of Packaged Boilerhouses designed in cooperation with our customers in order to guarantee safety, reliability and quality of the supply. The systems are designed to the latest standards of plant requirements and to a required efficiency performance. t is an ideal solution where it is impossible or impractical to find the space for a new boilerhouse or an existing boilerhouse that cannot be upgraded. Our product range comprises light compact designs for commercial heating systems and for larger industrial applications.

Energy saving and environmental protection are fundamental to the basis of the boiler design and research.

RESEARCH AND DEVELOPMENT We are involved in state of the art boilers, owing to 5 years of technological progress. Our resources for research and development are focused on two main features: ndustrial systems, where research integrates components with boilers to achieve higher efficiency, together with easytouse operation and low emissions. The development of new electronic control systems allows us to save on personnel and boiler remote control. Commercial heating systems, where the matching of boiler and heat metering units allow a considerable efficiency increase of the building; moreover, the integration with solar panels and renewable energies helps to cut on heating costs and offers a better environmental impact. We take care of pollution and environmental respect, as a matter of fact our new developing technologies allow a considerable reduction of carbon dioxide and other pollutant emissions such as carbon monoxide and NOx. Our research on fuel cells and steam reformer presents Sidera 3 at a further evolution on heating plants integrating the production of electricity. The innovation of our project consists in the use of hydrogen as fuel, presently obtained by reformed natural gas.

FN THE 3 STARS EFFCENCY SYSTEM patented by C Caldaie Fine is a system that increases the boiler efficiency up to the 3 stars level according to the European norm 192 issued on August 19, 25: energy saving reduces environmental impact. Fine is an aluminium extrusion, with internal fins, inserted on the back side of the boilers smoke tubes in order to guarantee the complete contact between surfaces. While flue gas transmits thermal energy along the finned surfaces, its own temperature is reduced before it reaches the smoke chamber and therefore it exits at the chimney at a very low temperature.

Solid fuel boilers Commercial Range SP PELLET FRED BOLER The Series SP are automated wood pellet fired boilers, complying to norms EN1289 and EN335 second. They are constructed from a body boiler in steel, with a pressure jet burner, a control system and a system of feeding to stoker. three pass design to ensure good solid fuel combustion the cleaning of the boiler is facilitated from the two fast opening and closing front doors large volume for the accumulation of ashes. complete combustion assisted by the grate design ensuring no unburnt carbon in ash. pellet burner is specially designed for the application on the biomass boilers with a high performance centrifugal fan producing a horizontal flame like traditional burners. The pellet fuel is fed through an auger which can be operated on / off, high / low and is complete with electronic control system. The combustion air is supplied by a variable speed fan which adapts to the demand for power and requirement of combustion air to suit the supply of fuel from the stoker.

Owing to the low water temperature in the boiler and the particular shape of the flue gas passages inner surfaces, the flue gases exiting from the outlet of the boiler pass into a flue gas condenser installed downstream of the boiler, where the temperature of the gases drop below dew point. The droplets of condensate are then conveyed into the specially inclined flue ways, in order to drain. The stainless steel AS 316 Ti horizontal gas passes are characterized by tapered projecting parts obtained from a pressed plate heat exchanger.

The very low thermal capacity, for a reduced use of refractory cement, allows reliability against superheating risks even, at worst, during oil circulation stopping. OPX REC is generously sized with low heat release criteria, manufactured incorporating the latest technology and providing excellent performance. Before being expelled to the chimney, the flue gases pass through a builtin recuperator where the flue gas temperature is further reduced by preheating the combustion air, thus achieving a global efficiency over 91%. The hot air is then carried to the industrial type burner which is always supplied with the OPX REC heater. Oil side pressure drop Working T max.
