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 sonnel 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.
