Base Equipment and Options (A - B)

KEYDESCRIPTION
AFRAir Filter/Trap/Regulator.  High volume air filter, moisture trap and pressure regulator to assure supply compressed air is clean, dry and at the proper pressure before entering the furnace.  Option available on most furnaces.  IR Furnace Optional Equipment
AR1Gas Reservoir (Belt Tensioner).  Pressurized gas system with tank, check valve and separate regulator to maintain constant pressure on belt even during short term failure or disconnect of the supply gas.  Standard on all furnaces.  IR Furnace Stardard Equipment
AR10Air Reservoir, System Purge.  Adds 30-56 L (8-15 gal) reservoir for supplying process gas in adequate quantity to assure purging the furnace chamber of volatile or toxic gas in the event of a plant power failure.  System includes pressure switch and alarm integrated with the OI.  Standard on some applications, option available on most furnaces.  IR Furnace Optional Equipment
BEEntrance Baffle with Eductor. The Entrance Baffle/Exhaust Eductor is a 38.1 cm (15 inch) long section that serves to isolate the furnace atmosphere from the facility atmosphere.  The entrance baffle is housed inside an aluminum shell lined with ceramic fiber insulation and includes a metal air rake to introduce a gas curtain above the belt.  This gas curtain purges the baffle and a series of four equally spaced hanging baffle gates prevents ambient air from entering the furnace chamber.   A venturi-assisted exhaust stack (eductor) draws gases from the entrance of furnace zone 1, across a drip tray and out of the furnace to prevent exhaust condensation from falling into the entrance baffle.  Proper operation of this system keeps the furnace interior clean. Standard on most furnace models.  IR Furnace Stardard Equipment
BNVBelt, Ni-Chrome V.  The high temperature belt is a balanced spiral weave of 18 gauge wire wound with 16 gauge cross wire of Nichrome V, 80%Ni/20%Cr alloy (<1% Fe).  Because of the balanced construction, it is 50% stronger than conventional weave and any belt tendency toward side travel is greatly reduced.  Standard on HT high temperature furnaces (>550 C), option available for most furnaces.  IR Furnace Stardard Equipment   IR Furnace Optional Equipment
BSSBelt, Stainless Steel.  The standard furnace conveyor belt is a balanced spiral weave of 18 gauge wire wound with 16 gauge cross wire made of type 316 stainless steel.  Because of the balanced construction, it is 50% stronger than conventional weave and any belt tendency toward side travel is greatly reduced.  Standard on low temperature (<550 C) furnaces.   IR Furnace Stardard Equipment
BXExit Baffle with Eductor.  The Exit Baffle/Exhaust Eductor is a 38.1 cm (15 inch) long section that serves to isolate the heating chamber from the ambient atmosphere at the furnace exit. The exit baffle is housed inside a metal shell lined with ceramic fiber insulation and is fully insulated so that it will lose heat gradually. The baffle includes a metal air rake to introduce a gas curtain above the belt to purge the baffle and a series of four (4) equally spaced hanging baffle gates to effectively isolate the high temperature furnace section from the ambient atmosphere at the furnace exit. A venturi-assisted exhaust stack draws furnace gases from the last zone, across a drip tray and out of the furnace to prevent exhaust condensation from falling into the exit baffle.  Proper operation of this system keeps the furnace interior clean.  Standard on most furnace models.  IR Furnace Stardard Equipment
BXOExit Baffle.  The Exit baffle is a 38.1 cm (15 inch) long section that serves to isolate the closed atmosphere cooling section from the ambient atmosphere at the furnace exit.  The exit baffle is housed inside an aluminum shell lined with ceramic fiber insulation. The baffle includes a metal air rake to introduce a gas curtain above the belt to purge the baffle and a series of four equally spaced hanging baffle gates to effectively isolate the controlled atmosphere cooling section from the ambient atmosphere at the furnace exit.  Standard on some furnace configurations.   IR Furnace Stardard Equipment
