PUR-Therm Gas Delivery Heaters are designed to heat carrier and process gases much more efficiently than silicone gas line heaters while maintaining Ultra High Purity specifications. PUR-Therm Heaters are easily incorporated into gas cabinets using industry-standard process controls (PID, PLC, etc.) and UHP VCR fittings.
Our standard 200 and 300 mm platens are available with or without a hard anodized finish (MIL-A-8525, Type III, Class 1). These platens are also equipped with three lift pin holes, 3.2 mm thru. Our standard cleaning process for these units includes a deep ultrasonic wash followed by a thorough IPA wipedown.
The development schedule for our 200 and 300 mm replacement platens included a full array of engineering tests – from FEA thermal simulations, to Sensarray temperature uniformity tests (see here) and accelerated life cycle testing – all of which helped these products achieve the thermal performance and real-world field reliability CAS is known for.
To verify dimension and deflection compliance, all CAS products are inspected using state-of-the-industry coordinate measuring machines (CMM), accurate to within a fraction of a micrometer. To verify electric component compliance, each heating element array undergoes a series of ohms resistance and high potency tests.
The full-service lab includes digital x-ray and ultrasound equipment, key tools for evaluating the quality of castings and verifying the location of heating elements. These powerful instruments are employed in the prototype test phase of almost every CAS product, and as part of standard test protocols for many production-level components.
