Made in Japan

Manufacturer: Tokyo Keiso

Model: CLFC300

The CLFC300 series is flow controller which integrates all functions of an ultrasonic flowmeter, a control valve, and a circuit for flow computation and valve control. Its control function can quickly follow the target flow rate.
Thus, the CLFC300 is ideal for liquid control which is essential in semiconductor manufacturing for the constant supply of chemicals and flow control of DIW and slurry.

Features

• Improved flow measurement

Flow measurement is stabilized by faster calculation and improved bubble resistance.

• Excellent controllability

A quick step response is achieved by state-of-the-art signal processing technology. The CLFC300 tracks variations in the flow and returns it to the set point within 1.5 seconds.

• Two valves for wider applications

A needle valve is available for chemical liquids and DIW, and a pinch tube valve for slurry liquids. The STA-PURE style pcs tube is added to the lineup of pinch tubes. This tube has excellent durability and does not need to be replaced regularly.

• Lightweight and compact

An ultrasonic flowmeter, a control valve, and a circuit are all contained in a single case. In addition, the layout was revised to make the controller more compact: it is now 20% smaller and 35% lighter.

• Easy installation

No complicated piping or wiring is required: simply connect the fittings and multi-core cables to complete the installation.

• Eco-friendly

Power consumption is reduced by 35%. All parts are complied with the RoHS requirements.

• Corrosion-resistant

The CLFC uses highly-corrosion-resistant PFA and PTFE for wetted parts and ultra-durable PVDF for the case.
It is ideal for the semiconductor industry and other industries that use corrosive chemicals.

• EMC-compliant

The controller conforms to EN 61326-1: 2006.

Applications

• Constant feed of chemical liquids and DIW

The CLFC300 ensures accurate and stable feed control of chemical liquids and DIW, which was conventionally conducted by metering pumps and static head tanks.

• Control of concentration

When CLFC300 are installed both in chemical liquids and pure water lines, they help directly dilute chemicals with pure water while controlling the concentration accurately and stably.

• Constant feed of slurry

The CLFC300 on various slurry lines of CMP devices ensures stable and constant feed of slurry and saves valuable liquids.
