Caloritech™ 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 elements. 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. It is used primarily to heat water in tanks through natural convection currents. Typical heaters have standard 1" - 2-1/2" npt tapered plugs. Other sizes or plugs are available on special order. All thermostat equipped screwplug heaters with moisture or explosion-proof housings feature a convenient terminal block mounted to a slide out trolley. 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. Installation - listed heaters have standard 1in. To 2-1/2 in. 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
