This pedestal heater design is ideal for heating large 450mm wafers inside of vacuum process chambers. The part is manufactured using our proprietary low pressure permanent mold casting process with electrical heater elements "Cast-in." An electron beam welding process joins an aluminum 6061 shaft to the cast aluminum 356 body to provide an electrical feed-through for electrical connections. The final assembly is precision machined into a wafer pedestal heater. Following a full inspection and cleaning, the part is complete and ready to install. Our base design and manufacturing processes can be modified to meet specific requirements, including customized machining, coatings and assembly.

• Size limitUp to 52" x 22"
• High Temp Limit700 Degrees F

At CAS one of our specialties is producing the highest quality commercial grills available. Our grills meet the needs for today's high volume cooking applications. Our low porosity, high temperature uniformity grills recover quicker when raw, cold or frozen items are placed on them. This allows for more efficient cooking, and greater productivity, increasing total output per KW. High temperature uniformity also ensures proper cooking regardless of item location, lowering the risk of under cooked product leaving the grill. CAS manufactures your grill to your precise specifications and offers engineering support ensuring your grill meets all your customers needs.

CAS’s family of heaters are ideal solutions for demanding applications. These heaters consist of a helical coiled tube and tubular element cast into an aluminum body. The aluminum body serves as the heat transfer media between the tubular element and the coiled fluid or gas transfer tube. The unique construction of the heater allows it to be used where thermally sensitive materials such as paints and resins or flammable materials such as fuels and solvents are being heated. The aluminum mass acts as a “thermal flywheel” and ensures accurate temperature control of the fluid. Many of our circulation heaters are available with optional explosion-proof enclosures for use in flammable environments. The CAST-X line of circulation heaters are well suited to applications where fluid cleanliness is critical because the material being heated never comes in contact with the heating elements. This is a performance requirement in the food service equipment, semiconductor and analytical industries. These heaters also come with a heavy wall seamless stainless steel passageway that assures performance in high-pressure applications where viscous or mildly corrosive materials need to be heated.

Allows Safe Heating of Volatile Silicon Wafer Cleaning Solvents The Universal Solvent circulation heater from CAS consists of a cylindrical-shaped cast part with helical coiled tubes and formed tubular heating elements cast-in. Three Type J thermocouples sense the solvent inlet, solvent outlet and casting core temperatures. The Universal Solvent circulation heater operates at near 100 percent efficiency while reducing the risk of solvent contamination. The Universal Solvent circulation heater provides a safe and efficient means of heating low flash point solvents. Both the heating elements and the solvent tube are cast into the aluminum. The heating elements provide heat to the aluminum mass and the mass transfers this heat to the tube carrying the solvent. The casting can also be surrounded by insulation to minimize heat loss and keep equipment cabinet temperatures low. A secondary chilled water tube is also cast-in. This tube quickly cools the casting for routine maintenance or lowers the solvent below the flash point. Safety features of CAS’s Universal Solvent circulation heater include a NEMA 7 rated (explosion proof) enclosure box covering the electrical connections and a snap-action over temperature protection switch to provide safe shut down. The casting body is Teflon® coated to protect the aluminum in case of accidental contact with solvents. The Universal Solvent circulation heater is appropriate for numerous applications and may be customized to meet specific customer needs.

The need for maintaining an ultra pure environment has lead to the development of pure aluminum cast-in heated parts. CAS now has the capability to cast complex heated shapes in 99.7 percent pure aluminum that limits process contamination and offers increased operating temperatures up to 450°C (842°F). Pure aluminum cast-in heated parts provide higher maximum operating temperatures over the more typical aluminum casting alloys. This equates to a 25 percent increase in process temperatures, resulting in an additional 90-130°C operating range. Thermal conductivity is also improved more than A356 alloy. Designed and engineered to customer specifications, CAS’s low-pressure casting technique and CNC machining ensure consistent quality heated parts. Many types of tubing can be cast-in to produce a circulation heater or add cooling capability for heatcool applications. With a modern and innovative aluminum foundry on site, and over 75 years of experience in manufacturing heaters, CAS has refined the technique to allow pure aluminum alloys to be cast with the same precision as more typical aluminum alloys. CAS’s custom designs are backed by strong engineering support, expert heater knowledge, metallurgical expertise in foundry practice and precision machining using CADCAMCAE and CNC manufacturing techniques. Pure aluminum cast-in heated parts are produced at CAS’s ISO 9001 registered facility in Batavia, Illinois.
