CAS CAST-X 1000 Circulation Heater

Compact cast-aluminum circulation heater for liquids and gases — 700 W to 3 kW total, 120–480 V, media isolated in a seamless 316L stainless flow tube rated to 2100 psi (144 bar), with NEMA 1 or NEMA 4 enclosure options and optional built-in thermostat.

Key advantages

Isolated flow path — media stays in seamless 316L SS tubing; no contact with heating elements (Inconel / passivated / electropolished upgrades).
700 W…3 kW — voltage range 120–480 V; max line current 15 A; single-circuit OEM codes.
High pressure — max 2100 psi (144 bar) on 0.313 in (5/16 in / 7.9 mm) OD × 0.020 in wall tube; overall process length 137 in (3480 mm).
Self-draining, non-welded cast body — compact footprint for OEM equipment; insulating jackets and compression fittings available.
Sensors / limits — J/K thermocouples, RTD, snap-action high-limit, enclosure-mounted thermostat options per OEM PN tables.

Typical applications

Engine and compressor pre-heating.
Solvent heating for wet-bench processes; hydrogen peroxide and IPA vaporization.
Commercial foodservice machines; compressor condensate evaporation.
Steam generation; air, CO₂, and nitrogen heating.

Selection guide

Power / voltage — OEM codes cover 750 W…3 kW at common line voltages (120 / 208 / 230 / 240 / 480 V examples on product page).
Enclosure — no enclosure; NEMA 1 (general-purpose); NEMA 4 (moisture-resistant).
Working temperature (housing @ 12 o’clock) — no enclosure 662 °F (350 °C); NEMA 1 608 °F (320 °C) / with thermostat 250 °F (121 °C); NEMA 4 482 °F (250 °C) / with thermostat 250 °F (121 °C).
Sensors — none, J/K single or dual, RTD, or 30–250 °F thermostat (NEMA 1/4 codes).
Tube options — passivation (P), electropolish Ra 10 µin (EP), or both (EP-P); Inconel/Monel/Hastelloy as custom.
Accessories — compression fittings 274-55-6-4; insulation jackets 307-0-2-1 (400 °F) or 307-0-20-1 (986 °F).

Common mistakes

Ordering a thermostat enclosure when process temperature must exceed 250 °F (121 °C).
Skipping passivation/EP when the duty is high-purity or sterile.
Assuming NEMA 7 / ATEX availability on CAST-X 1000 — OEM lists NEMA 1/4 (and no enclosure) for this model.
Leaving voltage/circuit code blank — CAST-X power is set by the AAAA voltage/wattage matrix.

When to RFQ / what to tell us

Line voltage, target watts, and preferred single-phase circuit code (AAAA).
Enclosure + sensor code (BB); high-limit switch need (C).
Tube finish (P / EP / EP-P) or alloy upgrade; metric mounting (M) if required.
Accessories (fittings, jackets); quantity; ship-to country.

FAQ

Q: What media can CAST-X 1000 heat? A: Liquids and gases. Media stay inside the seamless tube and never touch the cast-in elements, per CAS.

Q: NEMA 1 vs NEMA 4? A: NEMA 1 is general-purpose/dust-proof; NEMA 4 is moisture-resistant. Working-temperature limits differ — state ambient and process temp on the RFQ.

Q: What should I send for a quote? A: Voltage/watts, enclosure/sensor code, tube finish, accessories, quantity, ship-to. Compatible with systems using CAS CAST-X 1000 if you need a drop-in check — we do not claim authorized-dealer status.
