Inditherm offers a full range of solutions for heating multiple chemical
dosing lines in water and waste water treatment works. These use Inditherm's low
voltage CPT encased in waterproof, removable jackets that can encase several
chemical dosing lines within the same jacket. Not only does this save energy
but makes maintenance and modifications to the line system very easy.
Some chemicals start to crystallise at low temperatures and it is necessary
to apply heat to keep them liquid. For example, 50% Caustic solution starts to
thicken at around 16 °C and starts crystallising at around 8 °C. Traditionally,
electrical trace heating has been used to keep chemicals liquid. The individual
lines are then lagged to prevent heat loss. However, there are several
limitations to this solution:
- Each line needs to be individually traced and clad.
- Installation time is significant.
- Power consumption is high (typically 10-25 W/m/line).
- Voltage (110V or 230V) requires special safety
considerations.
- It is not possible to examine or maintain the lines
without removing the cladding and insulation.
- It is often necessary to put in underground channels
to protect the lines.
- Different parts of the lines cannot easily be individually temperature
controlled.
Laying the dosing lines inside Inditherm heated jackets solves these
problems:
- Multiple lines can be laid inside a single jacket,
saving space.
- Installation time is cut dramatically (typically by a
factor of 3 or more), due to jackets being manufactured off site and holding
multiple lines. This also reduces the health & safety exposure for
contractors.
- Power consumption is reduced significantly, and
depending upon the number of lines in each jacket and the average ambient
temperature, can be reduced to between 24W/m/tray and 50W/m/tray.
- Low voltage (24Vac) is very safe, particularly in wet
environments.
- Jackets can be fitted into standard cable trays,
which do not need to be laid below ground, again saving overall project time
and cost.
- Each pad has an individual temperature control, so
will switch on automatically when needed, even if other parts of the line are
switched off because they are in a warmer area.
- The innovative design includes a cover secured by a continuous Velcro
strip. This allows them to be easily opened, enabling rapid access for routine
maintenance and quick replacement.
In addition, in the event that additional dosing lines need to be added
later, this can be done easily, provided there is space within the jacket.
Heating or insulation can also be provided for catchpots and point of
application boxes within the dosing line system.
Power is provided from one or more control panels that can be mounted around
the treatment plant close to the heating system.
