Cast X 500 Circulation Heaters from Watlow

Flow Factor can supply Watlow Cast-X 500 Circulation Heaters

Watlow, a designer and manufacturer of electric heaters, controllers and temperature sensors, announces the introduction of the CAST-X 500 circulation heater. This small, lightweight circulation heater is ideal for demanding gas and liquid applications, is intrinsically safe and will not burn the fluids being heated.

The CAST-X 500 heater is suited for applications where fluid cleanliness is critical because the gas or liquid being heated never comes in contact with the heater. This is a performance requirement in the semiconductor, analytical and foodservice equipment industries. The heater's applications include the heating of solvent, DI water, air, CO2, nitrogen, diesel fuel and printing ink, as well as packaging sterilization, analytical instrumentation, steam generation and pasteurization in foodservice applications.

The CAST-X 500 circulation heater is constructed of a helical coiled tube cast into an aluminum body with a replaceable cartridge heater installed in the center. The cartridge heater can be replaced with a higher or lower wattage unit as required for the application. The aluminum body serves as the heat transfer media between the cartridge heater and the coiled tube where fluid is being heated.

The unique construction of the heater allows it to be used where thermally sensitive materials are being heated, such as paints, resins and flammable materials. The aluminum mass acts as a "thermal flywheel" and ensures accurate temperature control of the fluid to prevent degradation.

The robust cast-in aluminum construction assures longer heater life and accurate temperature control, and the stainless steel fluid path assures compatibility with many different materials. The heater's non-welded construction provides high pressure operation up to 3000 PSI, operates up to 177°C (350°F), minimizes potential leakage and self drains when mounted vertically. Its compact size reduces space needs in customers' equipment and assures quick response due to its low mass, making it a better overall thermal solution than oversized heat exchangers.

The CAST-X 500 is the newest and smallest heater in Watlow's CAST-X product line. The CAST-X 1000 offers a maximum working fluid pressure of up to 1500 PSI and process temperature up to 121°C (250° F). The CAST-X 2000 features a maximum working fluid pressure of 5000 PSI and a process temperature of 93°C (200°F) to 260°C (500°F). Watlow is currently taking orders and shipping the CAST-X 1000 and 2000 in only one day.

Industrial Circulation / Tankless Heaters

Flow Factor provides in pipe heaters for heating liquids and gases.
Inline pipe heaters are also known as circulation heaters, tankless heaters, in-line heaters or instantaneous heaters.

Industrial circulation heaters are packaged units consisting of a screwplug or flanged immersion heater mounted in a thermally insulated heating chamber for efficient heating of a flowing medium by in-line (tankless) or side-arm operation. Thermocouple sensors can be provided to connect to most any controller. Select from many terminal enclosures, sheath and vessel materials, flanged connections, and controls. Many models in stock.

Circulation heaters provide a ready-made means to install electric heating with a minimal amount of time and labor. This is accomplished by combining heating elements, vessel, insulation, terminal enclosure, mounting brackets and inlet and outlet connections into a complete assembly.

Made from NPT screw plug or ANSI flange heater assemblies mated with a pressure vessel (tank), circulation heaters are designed to heat forced-circulation air, gases or liquids. Ideal for either in-line or side-arm operations, these assemblies direct fluids past FIREBAR® or WATROD™ heating elements, to deliver fast response and even heat distribution.

Applications include: Water Heating, Freeze Protection, Heat Transfer Oil Heating, Fuel Oil Heating, Stea, Air, and Gas Heating and others.

• Watt densities up to 120 W/in2 (18.6 W/cm2)

• Wattages to three megawatts

• UL® and CSA component recognition up to 600VAC (FIREBAR to 480VAC)

• Ratings to ANSI Class 600 pressure class

• Incoloy® sheath temperatures up to 1600°F (870°C)

• Passivated 316 stainless steel sheath temperatures up to 1200°F (650°C)

• Steel sheath temperatures to 750°F (400°C) • Copper sheath temperatures to 350°F (175°C) • Up to 3000psi design pressure

Clean Water Heaters are ideal for heating municipal water for industrial washing and rinsing processes. Other applications include indirect heating of viscous liquids and temperature maintenance of storage tanks.

Light and Medium Weight Oil Heaters are ideal for temperature maintenance and for improving flow characteristics of oils. Heavy or Fuel Oil Heaters will reduce the viscosity, thereby improving flow and process efficiency.

Industrial circulation heaters provide a cost effective means for heating air and common industrial gases such as Argon, Helium and Nitrogen. They can also be used to increase the enthalpy and quality of steam.

Mild corrosive heaters allow the heating of solutions using stainless elements and a passivated stainless pipe body. Highly corrosive solutions and oils can be heated with the low watt density INCOLOY® sheath elements coupled with a passivated Stainless Steel pipe body, providing long service life.

Typical Applications

Water: • Deionized • Demineralized • Clean • Potable • Process • Industrial water rinse tanks •

Lubricating oils at API specified watt densities • Heat transfer oil • Paraffin • Caustic cleaners •

Hydraulic oil, crude, asphalt

Nitrogen, hydrogen and other air/gas systems • Superheating steam

Wattages and Voltages

Watlow routinely supplies circulation heaters from 120 to 600VAC (WATROD to 600VAC) as well as wattages from 500 watts to three megawatts. If required, Watlow will configure circulation heaters with voltages and wattages outside these parameters.

Weatherproof Protective Steel Jacket (Shroud)

To protect circulation heaters from weather or wash-down conditions, fully welded (weatherproof) or partially welded (standard) outer protective steel jackets are available. Standard steel, or made-to-order 304 or 316 stainless steel can be supplied. Jacket diameter is dependent upon thermal insulation thickness.

Options

Stand-off Terminal Enclosures

Stand-off terminal enclosures help protect terminal enclosures against excessive temperatures.

ASME Pressure Vessel Code Welding

Flange or screw plug assemblies can be provided with an ASME Section VIII or Section I, Div. I pressure vessel stamp upon request.

Branch Circuits

Branch circuits are designed for 48 amperes per circuit maximum. Contact a Watlow representative for circuit requirements other than those listed in the stock charts.

Certified Assemblies

CSA, ATEX or IEC Ex certified moisture and/or explosion resistant terminal enclosures protect wiring in hazardous gas environments. These terminal enclosures, covered under CSA file number 61707, ATEX certificate # KEMA 07ATEX0172X or IEC Ex certificate # IEC Ex CSA 09.0010 are available on WATROD flange heaters.
