APPLICATIONS
Pure Water:
Heating of dem iner al ized or
de-ionized water that is highly
ag gres sive to mild steel.
Mildly Corrosive Solutions:
Heat mildly corrosive solutions
(pH5 to pH9) using stainless
elements and a passivated
stainless pipe body.
Highly Corrosive Solutions
and Oils: Low watt density
IN COLOY sheath elements coupled
with a passivated Stainless Steel
pipe body provides long service life
when heating highly corrosive
solutions and sulfur laden oils.
Steam Superheating: Increase the
enthalpy and quality of steam.
Smaller units can be used to make
up line losses in steam gen er at ing
and distribution systems.
High Temperature Gas:
INCOLOY el e ments and a Stainless
Steel vessel enhance safe operation
to nearly 1400°F outlet gas
tem per a ture in air, gas or steam
superheating ap pli ca tions.
FEATURES
Terminal Enclosures: Standard
stock heater terminal enclosure E1
General Purpose. Moisture
Resistant/Explosion Resistant E2,
Explosion Resistant E3 or Moisture
Resistant E4 Enclosures are
available as assembly stock.
Elements: Sturdy 0.475" Dia.
Stainless Steel or INCOLOY sheath
elements provide superior strength
and rigidity. OMEGALUX elements
utilize high quality resistance wire
for coil construction. The coil
is sur round ed with high purity
mag ne sium oxide which is
com pact ed to a dense solid to
ensure high thermal con duc tiv i ty
and dielectric strength.
Corrosion Resistance: NWHMTSS,
NWHIS and NWHOIS pipe bodies
and all Stainless Steel heating
elements are pas si vat ed to provide
additional resistance to corrosion.
Flanges: Type 304 Stain less Steel
flanges are standard on 3" and
larger circulation heaters. Flange
dimensions conform to ANSI B16.5
standards. Series NWHMTSS
heaters utilize a Stainless Steel
screw plug.
Vessels: Pipe body and nozzles
are type 304 ASTM A312 ERW
Stainless Steel pipe. The end
disks are type 304 ASTM A240
Stainless Steel plate. Provided with
thermal insulation and painted
sheet metal jacket.
Baffle Assemblies: Internal baffle
as sem blies are pro vid ed for model
GCHISB-18 heaters to increase the
velocity of the air, gas or steam as it
passes through the vessel. In creas ing the velocity of the gas helps
reduce the tem per a ture of the
element sheaths and the vessel walls
in critical applications.
Wiring: Wiring terminals are
spaced to provide proper arcing
and creepage clearances per
the NEC. Termination insulators
provide electrical isolation between
the terminals and the grounded
metal sheath to enhance per son nel
safety and equipment service life.
Heavy duty jumper straps and other
terminal parts assure tight
connections and an extra margin
of current carrying capacity.
G-33
Controls: All stock and assembly
stock heaters, Series MTSS, 03 and
06, come equipped with mechanical
AR thermostats. These thermostats
are suitable for most applications.
Explosion-resistant and liquid- tight
ther mo stats are provided on E2/E3
and E4 units, respectively. Individual
product pages list other types of
thermostats and controls available
for each heater. For heaters listed
without controls, refer to the Overview
on Mechanical and Electrical Control
Options in this section.
Precision Temperature Control and
Control Panels: For larger kW heaters
and precise control of gas
temperatures in high tem per a ture
applications, OMEGALUX
recommends the use of thermocouple
sensors, electronic PID temperature
controls and SCR power panels for
circulation heater applications. The
use of electronic and SCR controls
will minimize overshoot and reduce
the pos si bil i ty of heater damage from
overtemperature operation. Integral
or remote mounted control panels
with electronic controls and solid state
(SCR) or contactor power controllers
can be provided using virtually any
combination of control devices.
Consult the Controls section for details.
