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. These heaters can be equipped with factory-installed thermostats to manage liquid temperatures and are intended to be fully immersed at all times. Commonly, they have standard 1" - 2-1/2" NPT tapered plugs, with additional sizes available upon special order. Heaters featuring thermostats and moisture or explosion-proof housings incorporate a terminal block mounted on a slide-out trolley for ease of use. The installation process utilizes standard 1 in. to 2-1/2 in. NPT tapered plugs, with alternative sizes available on request. The heater is installed through a threaded half coupling positioned in the vessel wall below the minimum liquid level, ensuring sufficient space above the bottom to prevent sludge build-up. While horizontal installation is preferred for efficiency, vertical installation may be possible; consultation with the factory prior to purchase is recommended. In operation, immersion heaters create a balance between convection currents and temperature differentials to facilitate heat transfer, and it is essential to avoid overheating by maintaining the appropriate heat transfer rate from the elements.
