Heater Features

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.

High purity MgO powder compacted to provide maximum heat conductivity and optimum dielectric strength.

Type ‘A’ 80/20 resistance wire sized to provide lowest wire watt density for maximum life.

Fusion welded junction between pin/resistance wire to provide a 360″ circumferential joint, giving superior strength and life.

Recompacted bends to restore MgO density in bend areas.

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.

NEMA 1 wiring enclosure, NEMA 4 moisture tight enclosure on high capacity and suction heater units.

Element spacer supports on multi-element heaters whose length exceeds 18″.

Thermowell for sensing bulb of thermostat.

UL & CSA Recognition on elements.

Vessel Features

Galvanized pipe on most water heaters, carbon steel pipe on others.

1″ fiberglass insulation on all pipe bodies except where noted.

Painted steel shroud encasing insulation.

Heavy duty mounting lugs on larger units (2″ plugs and UP).

NPT inlet/outlet on sizes up to 8″ flange, flanged inlet/outlet on larger sizes.

Top or side mounted bulb and capillary thermostats standard on sizes through 8″ flange. Solid state controls on high capacity air and gas heaters.

All welded construction hydrostatically pressure tested for leaks. ASME section VIII, Division 1, code stamp “U” vessel available upon request.

Sediment drains standard on all liquid applications.
