ELECTRICAL SURFACE HEATING PROJECT SPECIALISTS FOR A WIDE RANGE OF APPLICATIONS AND INDUSTRIES
ELECTRICAL TRACE HEATING
The term "trace heating" describes the application of heat to the surfaces of pipelines,
tanks, vessels and similar items, whether continuously or intermittently, to raise and/or
regulate temperature around and inside those items.
The term "surface heating" is also
Electrical trace heating will:
protect your operations from frost damage
raise the temperature of your product storage and flows where required
maintain temperature of products within pipelines, tanks, vessels etc during manufacture
generally ensure that all vital product flows are kept moving and/or stored at the required temperature
In principle at least, there are very few factories or large buildings in the UK, or indeed worldwide,
which could not benefit from some form of electrical trace heating.
Your products may be sited in flame proof areas, in locations below freezing point, or high ambient
temperature locations. It makes no difference to our designers as the products available in the field
of surface heating can cope with all these situations.
There are many types of trace heating tapes and cables available on the market ranging from self
regulating heater tapes whose outputs vary dependent on the temperature of the product being heated,
parallel circuitry heater tapes which are fixed wattage regardless of the length and basically comprise
a new circuit every one metre, heating cables constructed from copper, cupro nickel or stainless steel
which cope with high temperature work in dangerous environments and corrosive environments etc series
parallel circuitry heater tapes constructed from glass, fibre glass, mica etc.
Our designers at Peter Evans 'Bolton' Limited understand the different properties of all these options.
Armed with all this knowledge and experience, we can offer our clients carefully selected products
and specifications to suit their requirements.
RUNNING COSTS AND MAINTENANCE
Electrical trace heating is basically a maintenance free concept as, with thermostat controls or the
use of self regulating heater tapes, no electrical energy is wasted and the electrical trace heating
only operates when the process calls for heat. Combined with efficient and carefully considered
thermal insulation, the running cost of electrical trace heating is very viable as many installations
do not require much of an electrical loading above a mere 30 watts per metre. For example, in the
case of frost protection for sprinkler installations, the average loading is approximately 10 watts
In addition, when installations require modifications either extending, reducing or new tee off's
installed, electrical trace heating is sufficiently flexible to allow the circuits to be extended or
reduced without adversely affecting the capability of the installation.
It is a common misaprehension that, where steam is generated on site, pipe-work and tanks etc can be
surface heated by this method at no cost. In reality, due to the high maintenance cost of steam,
this is not the case. The comparatively small running cost of controlled electrical surface heating
with the obvious advantages of control, cleanliness and freedom from maintenance is a considerably
superior method of surface heating than steam, with its inherent problems of escapes etc.
