High-Temperature Resistant PTFE Wet Process Tank With 3KW Heater For Wet Etching

 

Core Advantages

• Ultra-high Corrosion Resistance: Compatible with all kinds of aggressive etching and cleaning chemicals, low maintenance cost and long service life.

• Zero Contamination: High-purity PTFE material will not precipitate impurities, guaranteeing high cleanliness requirements for semiconductor and precision electronics processing.

• Uniform & Stable Heating: Full-area heating design eliminates local temperature difference, improving etching uniformity and product yield.

• Safe & Intelligent Operation: Multiple safety protection mechanisms prevent dry burning, overheating and leakage, supporting 24-hour continuous industrial operation.

• Fully Customizable: Customizable tank size, heating power, voltage (220V/380V), installation method and accessory configuration according to customer’s production process requirements.

Key Material & Structural Features

1. Full PTFE Anti-corrosion Body
The tank body is made of high-purity PTFE (Teflon) with outstanding chemical inertness. It resists almost all corrosive liquids including hydrofluoric acid, nitric acid, sulfuric acid and mixed etching solutions, with a working temperature range from -20℃ to 260℃. The integrated seamless welding structure avoids liquid leakage, peeling and contamination, ensuring ultra-clean process environment. Optional double-layer structure (inner PTFE + outer PP/SS frame) enhances overall stability and durability.

2. Integrated PTFE Heating System
Equipped with dedicated PTFE immersion or frame-type heaters, the heating element is fully covered by PTFE layer, achieving direct contact heating with chemical liquid without chemical reaction or pollution. The heater features fast heating speed, even temperature distribution and long service life, perfectly solving the corrosion problem of traditional metal heaters in etching fluid.

3. Intelligent Constant Temperature Control System
Matched with high-precision digital temperature controller and high-sensitivity temperature sensor, the system supports precise temperature adjustment within 0–100℃. It realizes automatic constant temperature, over-temperature alarm and power-off protection functions, effectively preventing solution overheating and ensuring consistent etching quality in mass production.

Key Features & Advantages

Superior Chemical Resistance: PTFE resists most acids, alkalis, and strong corrosive media.
