A 9kW carbon infra-red
heating system from Heraeus
Noblelight is helping to
ensure consistent chocolate
quality while reducing
production line down-times
at OP Chocolate’s Dowlais,
South Wales, factory. The
system is used to pre-heat
chocolate moulds prior to
filling and replaces a longestablished
ceramic infra-red
system.

One third the size of the
old system, the new carbon
medium wave system
features three 3kW emitters
and can be either manually
or automatically controlled.

With manual control the
emitter outputs can be
adjusted by the operator to
achieve a mould temperature
of 30°C as measured by a
pyrometer. With automatic
control, the emitters are
regulated automatically
according to the pyrometer
setting.
