AccuTherm offers high quality circulation heaters, suitable for heating liquids and gases. A wide selection of tubular elements in stock provide quick delivery of our catalog heaters.
HEATER FEATURES:
| 1. | Incoloy® 840 sheath standard on all items except suction oil heaters-allows for the widest coverage of applications and temperatures, plus gives a margin of safety for unknown corrosives or contaminants. |
| 2. | High purity MgO powder compacted to provide maximum heat conductivity and optimum dielectric strength. |
| 3. | Type ‘A’ 80/20 resistance wire sized to provide lowest wire watt density for maximum life. |
| 4. | Fusion welded junction between pin/resistance wire to provide a 360″ circumferential joint, giving superior strength and life. |
| 5. | Recompacted bends to restore MgO density in bend areas. |
| 6. | Moisture sealed to prevent the entrance of contaminants during storage and service. Silicone end seals on heaters for oil, air and corrosive applications. Epoxy seals for water applications. |
| 7. | NEMA 1 wiring enclosure, NEMA 4 moisture tight enclosure on high capacity and suction heater units. |
| 8. | Element spacer supports on multi-element heaters whose length exceeds 18″. |
| 9. | Thermowell for sensing bulb of thermostat. |
| 10. | UL & CSA Recognition on elements. |
VESSEL FEATURES:
| a. | Galvanized pipe on most water heaters, carbon steel pipe on others. |
| b. | 1″ fiberglass insulation on all pipe bodies except where noted. |
| c. | Painted steel shroud encasing insulation. |
| d. | Heavy duty mounting lugs on larger units (2″ plugs and UP). |
| e. | NPT inlet/outlet on sizes up to 8″ flange, flanged inlet/outlet on larger sizes. |
| f. | Top or side mounted bulb and capillary thermostats standard on sizes through 8″ flange. Solid state controls on high capacity air and gas heaters. |
| g. | All welded construction hydrostatically pressure tested for leaks. ASME section VIII, Division 1, code stamp “U” vessel available upon request. |
| h. | Sediment drains standard on all liquid applications. |
Screw Plug Circulation Heaters feature Incoloy® 840 sheath for the widest coverage of applications and temperatures, NEMA 4 moisture tight enclosure, sediment drain, and NPT inlet/outlet.
Flanged Circulation Heaters feature Incoloy® 840 sheath for the widest coverage of applications and temperatures, NEMA 4 moisture tight enclosure, sediment drain, and 150 lb flanged inlet/outlet.
High Capacity Flanged Circulation Heaters feature Incoloy® 840 sheathed elements, carbon steel pipe body with 2″ high temperature insulation, and digital LED solid state control (0-1000 deg F) with thermocouple in outlet.
Suction Oil Circulation Heaters feature Incoloy® 840 sheath for the widest coverage of applications and temperatures, NEMA 4 moisture tight enclosure, and sediment drain. They are suited for large storage tanks of viscous fluids.
