Electrical heating technologies

This technical information series presents ten electric heating technology options to replace, supplement or optimise process heat currently being supplied by fossil fuels.
They detail the:
- technical features e.g. capacity, output, space and electrical loading requirements
- relevant process applications e.g. sterilisation, heating
- indicative capital, operations and maintenance costs
- greenhouse gas emission reductions compared to fossil fuel equivalents
- manufacturers, suppliers and installers
- case studies of the technology in use - mainly international examples
