A SUS304 flange heater is a critical heating component used in ultrasonic filter cleaning machines (超声波过滤器清洗机). It heats the cleaning solution to the optimal temperature, improving the effectiveness of ultrasonic cavitation and helping remove grease, oil, carbon deposits, and other contaminants from industrial filters.

What Is a SUS304 Flange Heater?
A SUS304 flange heater is an electric immersion heater made from SUS304 stainless steel, a material known for its excellent corrosion resistance, high-temperature durability, and hygienic properties. The heating elements are mounted on a stainless steel flange, allowing the heater to be securely installed in the cleaning tank.
Key Features
- Manufactured from corrosion-resistant SUS304 stainless steel
- Uniform and efficient heat transfer
- Easy flange-mounted installation
- Long service life in water-based cleaning solutions
- Suitable for industrial ultrasonic cleaning systems

How Does the SUS304 Flange Heater Work?
The working principle is simple yet highly efficient:
Step 1: Electrical Heating
When electrical power is supplied, the resistance wire inside the heating element converts electrical energy into heat.
Step 2: Heat Transfer
The generated heat is conducted through the SUS304 stainless steel sheath into the cleaning liquid, gradually increasing the solution temperature.
Step 3: Temperature Control
A digital thermostat or temperature controller continuously monitors the liquid temperature. Once the preset temperature (typically 40–80°C) is reached, the controller cycles the heater on and off to maintain a stable temperature.
Step 4: Enhanced Ultrasonic Cleaning
As the cleaning solution reaches the optimal temperature, the ultrasonic transducers generate millions of microscopic cavitation bubbles. The heated liquid improves cavitation efficiency, allowing bubbles to collapse more powerfully and remove contaminants from filter surfaces and internal pores.

Why Is Heating Important in an Ultrasonic Filter Cleaning Machine?
Heating significantly improves cleaning performance because it:
- Reduces the viscosity of oils and grease
- Accelerates the action of cleaning chemicals
- Improves ultrasonic cavitation efficiency
- Shortens cleaning cycles
- Produces cleaner filters with less energy consumption
- For most industrial filter cleaning applications, a solution temperature between 50°C and 70°C provides excellent cleaning results.
