Key parameters
High-purity cast-aluminum circulation heater with a field-replaceable PFA (Teflon) flow tube — 1.5 kW to 4.5 kW, 120–415 V, media isolated from heating elements, Teflon-coated body, NEMA 7 explosion-proof enclosure, max working temperature 392 °F (200 °C) and max pressure 70 psi (4.82 bar).
Key advantages
- Replaceable PFA flow tube — high-purity or SEMI F57 high-purity option; no service call required to swap the tube.
- Isolated media path — fluid never contacts heating elements; safe for many caustic solvents and process gases.
- 1.5…4.5 kW — single- or three-phase tables; max 30 A per circuit.
- NEMA 7 enclosure — explosion-proof housing; three J or K thermocouples (process, high-limit, tube protection).
- Teflon-coated aluminum body — cleanliness focus for wet-bench and semiconductor duty.
Typical applications
- Semiconductor wafer cleaning (wet bench); photo-resist removal solvents.
- DI water heating for wafer rinsing; air/N₂ heating for wafer drying.
- Heating of acids, IPA, Piranha, NMP, and similar chemistries.
- Single-pass or recirculating high-purity loops.
Selection guide
- Circuit / power (AA) — OEM codes 10…22 covering ~1.5…4.5 kW at 120–415 V (delta/wye/single-phase).
- Tube material (BB) — 00 standard PFA or 01 high-purity PFA (SEMI F57); 0.375 in OD × 0.031 in wall; length 190 in (4826 mm).
- Sensors (CC) — JJ (Type J) or KK (Type K); qty 3 standard.
- Mounting — optional metric M8×1.5 (D=M).
- Accessories — PFA straight unions 274-131-1-3 (SEMI F57); insulation jacket 307-0-18-1.
- Limits — max pressure 70 psi (4.82 bar); max working temp 392 °F (200 °C).
Common mistakes
- Ordering standard PFA when the process requires SEMI F57 high-purity tubing.
- Expecting CAST-X stainless-tube pressure ratings — PUR-X PFA path is 70 psi max.
- Skipping tube-temperature protection TC needs when specifying controls.
- Assuming field tube replacement without stocking the matching PFA fittings.
When to RFQ / what to tell us
- AA voltage/circuit/watts; BB standard vs high-purity PFA; CC J vs K.
- Metric mounting; fittings and jacket need.
- Chemistry, flow, target temp, single-pass vs recirculating.
- Quantity and ship-to country.

FAQ
Q: Why PFA instead of stainless? A: PUR-X isolates media in a replaceable PFA tube for high-purity / caustic solvent duty where stainless CAST-X tubes are not preferred.
Q: Can I replace the tube in the field? A: Yes — OEM states the flow tube is field-replaceable without a service call. Order matching PFA fittings with the heater.
Q: What should I send for a quote? A: Voltage/watts, tube purity, TC type, fittings/jacket, chemistry/temp, quantity, ship-to. Compatible with systems using CAS PUR-X 1000 if you need a drop-in check — we do not claim authorized-dealer status.
