Designed for heating plating solutions with exceptional chemical resistance to aggressive acids.

immersion heaters are the perfect solution for heating harsh chemicals or DI water to constant temperatures in ultrapure tanks, including PVDF, PFA, and quartz tanks. PFA/PTFE wetted surfaces are ideal for use in high-purity applications where chemical compatibility is of utmost importance. This element to provide high-efficiency heating with superior temperature control and maximum power output in a compact footprint. The heaters are available in various sizes that easily fit new and existing systems common to semiconductor, solar, MEMs, and other technological industries.

• Excellent chemical resistance to aggressive acids
• Spiral element design with low watt density
• Fluoropolymer (PTFE) sleeved 304 stainless elements
• Exceptional durability and corrosion resistance
• Built-in thermal protector and grounded element
• Available in single-phase configurations from 500 to 9000 watts and 120 to 600 volts

How Does the PTFE Immersion Heater Work?

PTFE immersion heaters work through a combination of resistive heating and the insulating properties of PTFE. Here's a breakdown of how they operate:
1. Heating Element: PTFE immersion heaters consist of a heating element typically made from a resistive material such as nickel-chromium (Nichrome) wire. This heating element is enclosed within a sheath made of PTFE, which is a highly non-reactive and insulating material known for its excellent chemical resistance.
2. Electricity Supply: When the PTFE immersion heater is connected to an electrical power source, electricity flows through the heating element. The resistive heating element offers resistance to the flow of electricity, causing it to generate heat as a byproduct.
3. Heat Transfer: As electricity passes through the resistive heating element, it heats up. The heat generated is then transferred to the PTFE sheath surrounding the heating element. PTFE has a high melting point and is an excellent insulator, which helps to contain the heat and prevent it from dissipating into the surrounding environment.
4. Immersion in Fluid: PTFE immersion heaters are designed to be submerged directly into the fluid that requires heating, such as water, oils, or chemicals. As the PTFE sheath heats up, it transfers the heat to the surrounding fluid through conduction.
5. Uniform Heating: The design of PTFE immersion heaters allows for uniform heating of the fluid, ensuring that the entire volume is heated evenly. This is important for applications where consistent temperature control is required.
