Protec Fluoropolymer (PTFE) Heaters -
Protec PTFE heaters are ideal for the heating of pure or corrosive liquids within tanks. PTFE is usually selected for the superior corrosion resistance and compared to metals. Unlike most of the other Protec heaters that use large single tube, the PTFE heaters use a smaller diameter continuous element. The use of the smaller diameter offers greater flexibility in the design of the heater in that the element can be formed in many different shapes to best suit your application. These heaters are available in units up to 27 kW.
Safety against over heating
PTFE heater are protected against over heating by using Protector I - PTI or Protector II - PTII resetable thermal fuses. The Protector System is used as a safety device in the event that the heater is exposed to air instead of liquid. The sensor within the PTFE covering will trigger the heater controller to turn the heater off in the event of excessive temperatures.
Note: Most heaters are supplied with thermal overload protection - please advise desired solution temperature for correct sizing of protection fuse.
The shapes are selected to take the minimum amount of room within tank for the heater and allow for the maximum amount of space left in the tank for your process.
Tube heater can be constructed in nearly any custom shape for special applications.
