Product Details
Caloritech™ CX series screwplug immersion heaters are specifically designed for water heating in tanks or vessels, featuring brass screwplugs with NPT-style threads and copper sheath elements. The heaters come with the option of factory-installed thermostats to regulate liquid temperatures and must remain fully submerged in liquid at all times. Typical dimensions include standard 1" to 2-1/2" NPT tapered plugs, with other sizes available upon special request. For models equipped with thermostats, moisture or explosion-proof housings incorporate a convenient terminal block on a slide-out trolley. These electric heaters provide nearly 100% efficiency, safety, ease of control, and typically require less installation cost compared to gas or oil alternatives. Installation involves the use of a threaded half coupling mounted in the vessel wall well below the minimum liquid level, with sufficient spacing above the bottom to prevent sludge build-up. While horizontal installation is preferred, vertical installation may be feasible with factory consultation. Operational efficiency depends on maintaining a balance between convection currents and temperature differentials, particularly in viscous liquids that impede heat transfer.
