Process Temperature Maintenance
When is process temperature maintenance trace heating required?
Many products need to maintain a specified temperature in
order to remain in a liquid state for processing. This
temperature is usually far above the temperature of the
surrounding air.
When pipework is subjected to low ambient temperatures or
under no flow conditions, heat loss can cause the contents
viscosity to increase. This may lead to the material solidifying
or setting within the pipework, either slowing down the
process or causing problems to pumping equipment.
Industrial applications for trace heating include…
Food Processing Factories
Chemical Industries
Oil Refineries Power Stations
Electric trace heating tapes are vital in ensuring that process
temperatures of pipes and vessels are maintained to allow
for smooth and efficient running of process plant equipment.
To minimise the effects of heat loss, trace heating is used in
conjunction with thermal insulation to supply a heat source to
replace this heat loos and therefore maintain the pipe
temperature. Typically a pipe sensing trace heating
thermostat is used to sense the pipe temperature and
energise the heating system when required.
By utilising the correct type of temperature maintenance
heating cable, thermal insulation and temperature control,
process pipework will operate efficiently for many years.
Why install trace heating for process temperature maintenance?
ESH temperature maintenance heating cable…
Generally constant wattage heating tape systems lend
themselves better to process temperature maintenance heat
trace applications. However, low to medium temperature
applications that do not require such precise temperature
maintenance parameters can be maintained with self
regulating heating tape systems.
Engineers and installers using process trace heating will
always have their own preferences as to the type of cable to
use. This is why at ESH we offer a comprehensive range of
both constant wattage and self limiting heating tapes to allow
the end user to utilise the system that best suits their
application and personal preference.
