The Company Coel Srl (Electro Mechanic Company) was established in 1950 for manufacturing electrical kilns for thermal treatments and artistic ceramics. In that period the company took part, with determinant contribution, to the industry development for tiles and table-ware by making a kiln with a range that would have qualitative results higher than the standard in existence.

In 1967, thanks to the cooperation of a group of technicians specialized in tunnel kilns, Coel expanded its activity in the sanitary ware and brick field by changing its name, at the same time, from Coel to Coel Tunnel. The name of Coel Tunnel became synonymous with guarantee of quality and seriousness. From 1980, following and anticipating the technical innovation requirements (with particular attention to the energy saving and flexibility), kilns with prefabricated structure were built to allow a fast installation.

Coel Tunnel now has a traditional range of tunnel kilns with prefabricated modules, suitable for average and big productions of sanitary ware. Such kilns have low thermal mass, with combustion systems provided with total pre-combustion burners. This system allows the free entrance of combustion gas into the kiln with controlled temperature, since the excess of air for smoke dilution is independent from the combustion air. For each consumption there is an optimal (stoichiometric) combustion air/gas ratio, and the excess of air for dilution is regulated according to the quantity requested, without disturbing the same combustion.

In the last years, Coel Tunnel has started the production of shuttle kilns with cars of big capacity, suitable for firing sanitary ware, table ware, porcelain, bricks, refractories etc., obtaining excellent results regarding the firing times and energy consumption. These fully automatic kilns with a large possibility of changing the firing cycle represent, in the intermittent kiln field, the best you can find in the ceramic firing technology Such kilns can use natural gas, L.P.G. and diesel oil fuels and are also electrically operated for a power of Kw. 2.500 and over. Coel Tunnel's installations in Italy and abroad demonstrate who Coel Tunnel is, and their commitment to success.
