CAS CAST-X 2000 Circulation Heater

Versatile cast-aluminum circulation heater for liquids and gases — 1 kW to 6 kW total, 120–575 V, media isolated in a 1/2 in 316L stainless flow tube rated to 5100 psi (351 bar), with NEMA 1, NEMA 4, or NEMA 7 enclosures in standard or standoff mounts.

Key advantages

Isolated 316L flow path — media never contacts heating elements; Inconel / passivated / electropolished upgrades.
1…6 kW — single-phase or three-phase delta/wye circuit tables; max 25 A per circuit.
High pressure — 0.50 in OD × 0.065 in wall; process tube length 150 in (3810 mm); max 5100 psi (351 bar).
Enclosure flexibility — NEMA 1 / 4 / 7; standard or standoff housing for higher working temperatures.
Control options — J/K TCs, RTDs, snap-action high-limits, enclosure thermostats; compatible with PID/PLC multi-loop controls.

Typical applications

DI water heating; cryogenic gas and LNG vaporization.
Two-part urethane and foam systems.
Anodizing and plating pre-wash heating; dye heating.
Air heating for coating drying applications.

Selection guide

Circuit / power — standard-mount codes 300A…300U and standoff 30SA…30SU cover 1…6 kW across common voltages.
Enclosure + sensor (BB) — NEMA 1 (S…), NEMA 4 (W…), NEMA 7 (E…) with thermostat / J / K / dual / RTD options.
Working temperature (housing @ 12 o’clock) — NEMA 1 482 °F (250 °C), with standoff 662 °F (350 °C); with thermostat 250 °F (121 °C); NEMA 4 350 °F (175 °C), with standoff 662 °F (350 °C); NEMA 7 482 °F (250 °C).
High-limit (C) — none; manual reset 260 °F; auto reset 500 °F (not with standoff designs).
Tube options — P / EP / EP-P; metric M8×1.25 mounting (D=M).
Accessories — fittings 274-55-6-5; jackets 307-0-11-1 (400 °F) or 307-0-21-1 (986 °F).

Common mistakes

Ordering a standard mount when standoff is required for the higher NEMA 1/4 temperature ratings.
Selecting a high-limit switch with a standoff design — OEM notes high-limits are not available with standoff.
Confusing CAST-X 2000 with CAST-X 2000 HT (higher temp / different tube duty) — state HT need explicitly.
Ignoring max 25 A per circuit when choosing single-phase high-watt codes.

When to RFQ / what to tell us

Standard vs standoff; AAAA circuit/voltage/watts code.
Enclosure + sensor (BB); high-limit (C) if allowed.
Tube finish (P/EP); metric mounting; jackets/fittings.
Media, target outlet temp, pressure, quantity, ship-to.

FAQ

Q: Standard vs standoff enclosure? A: Standoff raises allowable housing temperature on NEMA 1/4 (to 662 °F / 350 °C per OEM). High-limit switches are not available with standoff.

Q: What pressure rating? A: Max 5100 psi (351 bar) on the standard 1/2 in × 0.065 in 316L tube, per CAS.

Q: What should I send for a quote? A: Circuit/voltage/watts, standard vs standoff, enclosure/sensors, tube finish, accessories, quantity, ship-to. Compatible with systems using CAS CAST-X 2000 if you need a drop-in check — we do not claim authorized-dealer status.
