Wafer Cleaning, Rinsing, and Drying Applications

At Southeast Thermal Systems, we proudly distribute CAS’ high-performance fluid heating products, designed for both inline and recirculating tank installations. These heaters are essential for post-chamber wet bench and wafer drying processes, offering safe and efficient heating for flammable media without the risk of explosion or flashing.

Our range of inline heaters from CAS ensures precise and safe heating for silicon wafer wet bench processors, supporting etch removal and photoresist evaporation. All CAS heaters incorporate a critical ‘no contact’ design, where the heated media remains isolated within flow tubes, preventing contamination and direct contact with the heating element.

Specialty Circulation Heaters

solvent heater

Several models are compatible with heating solvents. With the “no contact design” it is just a matter of selecting your purity level, and wattage. Heaters can be configured to safely handle flammable, low-flashpoint solvents and acids.

Cast-X High Temp Circulation Heaters

High Temp Gas Vaporization & Heating

Semi engineers and scientists are constantly developing new vaporizing and catalytic applications, which often involve very high temps. The CAST-X High Temp line of heaters supports these innovations with operating temps to 600°C.

CAST-X Circulation Heaters

DI Water Heating

For water in the higher mega-ohm range, our CAST-X 316 stainless steel tube heaters work well: the tubes can be electropolished and passivated to enhance compatibility. For lower resistivity water, the tube material can be switched to Hastelloy or another alloy. PUR-X Heaters are also appropriate for DI Water, as they have a PFA tube.

Cast-X High Temp Circulation Heaters

Gas for Wafer Drying Applications

CAST-X 500 and 2000 Models equipped with EP and Passivated ID tubes are popular choices for heating N2 for wafter drying. If a non-metal tube is required, our PUR-X 1000 is an excellent choice.

PUR X CIRCULATION HEATERS

Warming of Carrier Gases

The PUR-Therm Heater was specifically designed for heating chamber carrier gases. The flow-tube meets Semi F-70 purity standards, and has orbitally-welded VCR fittings, for easy inline integration.

Circulation heater with Stainless Steel Tubes

CAST-X Heaters: Our CAST-X line of circulation heaters is available in 6 base sizes, with power ranges from .5 to 60 kW. Standard flow-tubes are 316 seamless SST, with EP options available. CAST-X circulation heaters are well-suited for heating DI water and other solvent removal products

Universal Solvent Heater

Universal Solvent Heater

Our Universal Solvent Heater is specifically designed to heat low-flashpoint photoresist solvents. Liquids are isolated in the main flow-tube, never touching the heating element. Multiple sensors and a secondary cooling tube provide outstanding operating temperature control. The terminal enclosure is rated NEMA 7 explosion-proof, and the heater body is Teflon®-coated for corrosion resistance.
