Product Description Guide: Quartz Immersion Heaters with Metal Elements:
National Plastic Heater's quartz immersion heaters are suitable for most acidic chemistries or solutions. They are composed of metal tubular elements which are encased within a heavy wall quartz outer sheath. Quartz chemical over the side heaters are suitable for all acid solutions except those containing hydrofluoric or fluorides. Their standard watt density is around 40 W/sq. in. for mild acids. Low watt density quartz over the side immersion heaters of 20 watts/sq. in. is recommended for heat sensitive or heavy acid solutions such as for nickel plating, electro-polishing or phosphoric acid. NOT recommended for alkaline or caustic solutions. They are available in single tube or three tube heater units which include a preset over temperature control.
Teflon immersion heaters have a .030 wall of Teflon covering a metal element. This heater has a positive metal ground and superior anti corrosive characteristics that make it ideal for immersion into solutions like HCL, HF, Nitric or Chromic Acid.
Quartz immersion heaters and Teflon immersion heaters over the side construction enable easy installation and replacement. Liquid tight terminal covers prevents entry of liquids. Thermostats or high limit thermal fuses are available as options and prevent heater damage due to loss of liquid or low liquid. Titanium immersion heaters are available that are highly corrosive resistant and can withstand harsh chemicals and environments.
