DESCRIPTION
1.
Circulation heaters for liquid service are designed for operation
only while completely full with liquids. Never allow the heating
elements to be exposed while energized or failure will result.
CAUTION
CAUTION
Use the heater only in liquids
and at pressures for which it was designed
(unless specifically designed for non-liquid
applications). Normally copper sheath is
recommended in water, steel or alloy sheath
in oil, and the appropriate alloy sheath for
heating chemical solutions. Check factory for
recommendations.
2. Circulation heaters for gas service are designed to operate
under the design pressure and design temperature specified
in the pressure vessel ratings. High limit sensing devices
(thermocouples/RTD) provide means of control for the
maximum allowable temperature to operate the heater
below design conditions. Never operate the heaters beyond
limit temperatures specified in the heaters drawings. Never
operate the heater without a high temperature limits.
3. Circulation heaters are welded pressure vessels with inlet and
outlet connections to allow fluid/gas flow and heat transfer to
a customer flud.
4. Where gasket is required, user must ensure that gasket
surface is clean and dry before installing heater.
5. The terminals must be protected at all times from moisture
or vapour. In explosive atmospheres, explosion resistant
terminal housings must be used. In outdoor locations,
moisture resistant housings are required. It is recommended
to use a drip loop to prevent moisture from entering the
terminal box via the wire or cable.
6. Protect terminals of heating elements from drippings,
condensation, fumes, spray or any other substance which
could result in element contamination.
7. When melting solids by direct immersion, a surface vent
should be provided to allow gases to escape. Operate the
heater on ½ voltage until melted material completely
covers the heating elements. Heaters used for this purpose
may require special design features. Check factory for
recommendations.
