Caloritech™ CX Series Electric Screwplug Immersion Heater, 1"NPT , 0.75 kW, 120V

Description: Product SummaryCaloritech CX Series Screwplug Immersion Heaters are used primarily for water heating in tanks or vessels and have brass screwplugs with NPT-style threads and copper sheath element(s). Heaters are available with factory-installed thermostats to control the liquid temperatures. These heaters are designed to be fully immersed in liquid at all times. Application - Screwplug heaters are primarily used to heat liquids in tanks or vessels. To do so safely and reliably requires that the heating elements remain fully immersed in the liquid. Liquids such as water, oils, trichloroethylene, etc. can be heated through natural convection currents created by the immersed elements. Although electricity costs are generally higher than gas or oil, it can be demonstrated that a Caloritech immersion heater is often your best choice. The electric heater provides close to 100% efficiency, is safer and easier to control, and is usually cheaper to install. Terminal Block Simplifies Wiring - All thermostat-equipped screwplug heaters with moisture or explosion-proof housings feature a convenient terminal block mounted to a slide-out trolley. This unique Caloritech feature simplifies installation and reduces maintenance. Installation - Listed heaters have standard 1in. to 2 1/2in. NPT tapered plugs. Any other size or type of plug is available on special order. The heater is installed through a threaded half coupling located in the vessel wall well below the minimum liquid level but spaced sufficiently above the bottom to allow for sludge build-up which should never be allowed to cover any part of the elements. Horizontal installation is preferred even though heater replacement will require draining of the tank. Vertical installation is sometimes possible but it is best that you contact the factory for advice prior to purchase. Operation - For an immersion heater to transfer heat it must establish a balance between convection currents and the temperature difference between itself and the liquid. Viscous liquids which retard convection currents are the most difficult to heat. Care must be exercised to ensure that the required rate of heat transfer from the heating elements is achieved without overheating the element and the liquid resulting in coking. This is generally achieved through the selection of heater watt density. Heaters immersed in liquids, such as water with high calcium and magnesium content, phosphates or eluate solutions, have a tendency to precipitate their solids. These heaters require scheduled maintenance to remove scale build-up which may thermally insulate the elements and reduce their service life. Features + Benefits0.75 kW, Immersion Length: 5.5 Inches / 140 mmVoltage - Custom built heaters are available in any special voltage rating up to 600V.Wattage - Heaters listed are standard wattage. Any reasonable wattage is available to replace your present heater with a similar Caloritech™ unit.Length - Heaters are available with immersed lengths up to 135" (3430 mm). Internal vessel support must be used when the immersed length exceeds 49" (1245 mm).Plug Sizes and Ratings - Thermon Heating Systems can install elements in virtually any size or rating of plug, special or standard.Moisture Resistant Terminal Housings - Moisture resistant terminal housings suitable for outdoor applications are available for all heater sizes. Explosion-Proof Terminal Housings - If the heater is to be operated in a hazardous environment an explosion‑proof housing must be used. See Figure 5 on page B20. Specify Class, Div. (or Zone), Group, and Temp. Code for the hazardous location.For Models With a Built-in Thermostat -Standard built‑in thermostat is a one-pole device limited to 240V 25 amp. Whenever the heater voltage exceeds 240V or the heater current exceeds 25 amps or for three phase supply, the thermostat is intended for pilot duty only and is not factory wired to the elements. See Section F of the Caloritech™ catalog for the selection of the contactor and control transformer you may require in these instances.Heaters With Built-in Thermostats - All screwplug heaters listed are available with built‑in thermostats. Heaters with thermostats have a “T” added to their catalog no prefix. The standard thermostat range is 50°F to 250°F (10°C to 120°C). Ratings are normally 25 amps at 240V single pole single throw. 600V thermostats and double pole thermostats are available on special order.Special Thermostat Ranges - Thermostats with the following temperature ranges are also available upon request: 0°F to 100°F (-18°C to 40°C)150°F to 550°F (70°C to 280°C)300°F to 700°F (150°C to 370°C)Selection: Proper selection of the screwplug heater is required to maximize service life. Once the wattage requirement is established decide on heater voltage and phase. Remember that unrealistic heat-up time requirements will increase equipment and operating costs. The tables list, under “watt density”, the required heat transfer rate from the various heaters. Refer to Section D of the Caloritech™ catalog for guidance on the acceptable watt density for your application. If a heater is not listed with the density you require we can fabricate it to suit. Of equal importance is the selection of the materials of construction which will resist corrosion and not wear away or contaminate the liquid. Refer to the corrosion guide in Section D for a list of the standard materials for various solutions. Also, see page B26 for a discussion on watt density. The heaters are not guaranteed against corrosion since Thermon Heating Systems has no control over the liquid type, concentration, or temperature of the solution. Consult your factory representative or your chemical supplier for recommendations on materials for your solution. Recommendations are not implied guarantees.Warning - Fire Hazard: The heaters listed in the catalog may occasionally malfunction in normal use and if operated in the presence of explosive or combustible materials may cause fires. Do not operate in the presence of explosive or combustible materials. Observe fire prevention precautions and consult the local sales office or contact Thermon Heating Systems for proper installation.
