Caloritech CX Series 750 W 120 V 1Ø Screw plug Heater with Brass Plug, Copper Element and Thermostat - 1-in NPT

Caloritech CX Series screw plug immersion heaters are used primarily for water heating in tanks or vessels and have brass screw plugs 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. 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; Ensure that the required rate of heat transfer from the elements is achieved without overheating by selecting the heater watt density

• 3 kW, 10.8 Inches, 275 mm
• Application: Screw plug 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
• 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
• Installation : Standard 1 to 2.5-in NPT tapered plugs
• Heaters immersed in liquids have a tendency to precipitate their solids over the elements on heating; Regular maintenance to remove scale build-up tp extend element's service life
• Proper selection of the screw plug heater is required to maximize service life; Once the wattage requirement is established decide on heater voltage and phase; unrealistic heat-up time requirements will increase equipment and operating costs
• 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
