GENERAL
A Type K thermocouple is located inside the heating element
sheath to provide overtemperature protection. Accurate process control
can be achieved by means of the Type J thermocouple installed in the
heater outlet. (Process and Hi-limit Controllers ordered separately.)
WARNING: This heater is not intended for use in haz-
ardous atmospheres where flammable vapors, gases,
liquids or other combustible atmospheres are pre-
sent as defined in the National Electrical Code.
Failure to comply can result in explosion or fire.
WARNING: Users should install adequate back-up con-
trols and safety devices with their electric heating
equipment. When heating in closed vessels where the
consequences of failure may be severe, controls and
back-up controls must be used to prevent buildup of
temperature and/or pressure. Although the safety of the
installation is the responsibility of the user, Chromalox
will be glad to make equipment recommendations.
The GCHIS-C is a gas circulation heater, designed especially for
low flow rates and/or high temperature applications.
The INCOLOY® sheathed cartridge style heating element is cen-
tered in a 304 stainless steel pipe body. High temperature insulation
and jacket envelope the pipe body to reduce heat loss. Its screwplug
type mounting provides easy removal when necessary.
INSTALLATION
mounting lugs to support the heater chamber. Refer to figure for
location of these mounting lugs.
6. Mount heaters to permit unrestrained expansion of chamber due
to temperature. This can be accomplished by using slotted mount-
ing assembly on either of the lugs.
7. Provide adequate space at terminal end to permit withdrawal of
the heater from chamber should servicing be required.
8. DANGER: Hazard of Fire. Provide a minimum of 6” spacing
from chamber and related piping to nearest combustible material.
Do not operate heater near combustible fluids or in combustible
vapor or gas laden atmosphere.
WARNING: Hazard of Electric Shock. Disconnect all power
before installing heater.
1. Before installing, check your GCHIS-C circulation heater for any
damage that may have occurred during shipment.
2. Check to insure that the line voltage is the same as that stamped on
the nameplate.
3. Vertical mounting (axis of chamber vertical as in figure above)
is preferred.
4. To avoid excess temperatures at electrical wiring, mount heater
with terminal enclosure at bottom, and use lower nozzle as inlet
to the circulating steam, air or gas.
9. If two or more heaters are required to provide the needed heating
5. The GCHIS-C series of circulation heaters is provided with
capacity, arrange them for series gas or vapor flow.
