Screwplug Heaters – CX
Application
Type CXC heaters are used primarily for water heating and have brass
screwplugs and copper sheaths.
Type CXF are used primarily for oil heating and have steel screwplugs.
Low watt density heaters are used in heavier, non-circulated oils. Higher
watt density heaters are suitable for light oils or in forced oil circulation
loops. Incoloy® elements are silver brazed into a steel screwplug.
Type CXI heaters are used primarily for heating mildly corrosive
solutions and use higher density Incoloy® elements welded into a
stainless steel screwplug.
Built-in Thermostats
Standard built-in thermostat is a one pole device limited to 240V
25 amp. Whenever the heater voltage exceeds 240V or the heater
current exceeds 25 amps or for three phase supply, the thermostat is
intended for pilot duty only and is not factory wired to the elements. See
SectionF of the Caloritech™ catalog for selection of the contactor and
control transformer you may require in these instances.
