FR Option, Flex Riser for Electric Heaters

Product Features and Benefits:

APPLICATIONS: Provides simplified and versatile installation for L-shaped electric bottom heaters in various tank depths. The flex riser system saves dollars by reducing shipping costs since a parcel carrier can ship most heaters.

RUGGED CONSTRUCTION:

• STAINLESS STEEL HEATERS: braided 304 stainless steel sheath over a fluoropolymer (PTFE) inner tube.

• TITANIUM HEATERS: Fluoropolymer (FEP) tube with integral 316 stainless steel reinforcement.

• FLUOROPOLYMER (PTFE) HEATERS: continuous extension of tubing with inline junction box.

LONG LASTING PERFORMANCE: Liquid tight fluoropolymer tube is chemically inert and is protected by either a stainless steel outer braid (stainless steel heaters) or reinforced core (titanium heaters).

SAFETY FEATURES: Thermal protection standard on all flex riser heaters:

• Metal heaters: resettable P2 bi-metal switch.

• Fluoropolymer heaters: P3 J-type thermocouple.

CERTIFICATIONS: UL and CE.

SIZES:

• METAL HEATERS: 48-inch (1220mm) long, ž-inch (19mm) diameter, tubing for 500 to 18,000 watt heaters.

• FLUOROPOLYMER HEATERS: 48-inch (1220mm) long, 7/16-inch (11mm) diameter, fluoropolymer (PTFE) tubing with inline junction box. Connected to a 36-inch (915mm) long, ˝-inch (13mm) diameter, PVC conduit for 500 watt to 6000 watt heaters. 3-inch (75mm) minimum bend radius.

VOLTAGES: 120, 240 or 480 volts for various heater styles. 208, 380, 415, 600 and other voltages available. Single phase only for fluoropolymer heaters.

OPTIONS AVAILABLE (consult factory):

• Medium and high temperature resettable P2 bi-metal thermal protectors for metal heaters only.

• Special configurations and lengths.
