Caldo Environmental Engineering

Caldo has been a UK supplier of hot gas filtration equipment since 1992 and has made more than 60 successful installations on many different processes, all over the world.

Hot Gas Filtration Equipment:

Caldo hot gas filters use low density alumino-silicate ceramic filter elements in modular, purpose-built vessels. Often the filter is supplied complete with solids discharge system, vessel trace heating and insulation, and with an integrated control panel. Multiple filter vessels are used in parallel to achieve higher capacities.

Caldo ceramic filters have been used to filter gases on many processes:

• Incineration of various materials
• Burnout furnaces in lost wax foundries
• Plasma melting of catalyst for precious metal recovery
• Demilitarisation of munitions and chemical weapons
• Production of nano materials
• Gasification of waste wood and other materials
• Pyrolysis of waste plastics and other materials
• Manufacture of high performance ceramic fibres
• Sulphuric acid recovery

In all these various duties Caldo understood the requirements of the process and helped to establish how the ceramic filter would be best employed.
