Product Details
Caloritech™ CX series screwplug immersion heaters are primarily used for water heating in tanks or vessels and feature brass screwplugs with NPT-style threads and copper sheath elements. The heaters come with optional factory-installed thermostats to control liquid temperatures and are designed to be fully immersed in liquid at all times. Typical models have standard 1" to 2-1/2" NPT tapered plugs, but other sizes or plug types are available upon special request. All thermostat-equipped screwplug heaters with moisture or explosion-proof housings include a convenient terminal block mounted on a slide-out trolley. The installation process requires the heater to be fitted through a threaded half coupling in the vessel wall, positioned well below the minimum liquid level but above the bottom to prevent sludge build-up, and horizontal installation is preferred. The heaters operate by establishing a balance between convection currents and the temperature difference between the heater and the liquid, making them effective even for viscous liquids, which can be challenging to heat.
