The company COEL (electro mechanic company) was established in 1950 for manufacturing electrical kilns for thermical treatments and artistic ceramic.
In that period the company takes part, with determinant contribution, to the industry development for tiles and table-ware by making a kiln range having qualitative results higher than the standard in existence.
In 1967, thanks to the cooperation of a group of technicians specialized in tunnel kilns, it expands its activity in the sanitary ware and brick field by changing its name, in the same time, from COEL to COELTUNNEL.

The possibility to transmit its experience from a sector to another allows optimal results and to build tunnel kilns able to reach notably advanced performances. The name of COELTUNNEL became shortly synonymous of 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.

COELTUNNEL has now a traditional range of tunnel kilns with prefabricated modules, suitable for average and big productions of sanitary ware.
Such kilns have low thermical mass, with combustion system 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 therefore 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, COELTUNNEL has started the production of shuttle kilns with cars of big capacity, suitable for firing sanitary ware, table ware, porcelain, briks, refractories etc., obtaining excellent results regarding the firing times and energy consumption.
