AFR

Air 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. 

AR1

Gas 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.

AR10

Air 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.  

BE

Entrance 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. 

BNV

Belt, 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 high temperature furnaces (>550 C).  Option available for most furnaces.

BSS

Belt, 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.

BX

Exit 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.

BXO

Exit 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.

CACT

Closed Atmosphere Cooling Tunnel.  The CACT is a 76.2 cm (30 inch) long, high efficiency heat exchanger that reduces the temperature of the product. Inside the CACT, process gas flows through air rakes arranged two above the belt to cool the product to a safe temperature. To expedite heat removal, fans outside the chamber force ambient room air over the heat sink finned surfaces on the outside of the tunnel. Multiple tunnels may be joined end-to-end to obtain required cooling.  Standard on many furnace configurations, option available on most furnaces.

CAWC

Closed Atmosphere Water Cooled Tunnel. The CAWC is a 76.2 cm (30 inch) long, high efficiency heat exchanger that reduces the temperature of the product, but without externally mounted heat sink cooling fans. Instead, water flowing through chambers above and below the tunnel removes heat from the tunnel walls without adding to the heat load in the clean room. Includes OI integrated outlet water temperature sensors and alarms. Requires water supply and drain. Multiple tunnels may be joined to obtain required cooling. Upgrade from CACT.  Standard on many furnace configurations, option available on most furnaces.

CB-1

Circuit Breaker. Three phase circuit breaker. Required for UL approval.  Option available on most furnaces.

CDA-L

CDA Lockout. Manual lockout for CDA supply line, 1724 kPa, 250 psi.  Option available on most furnaces.

CDA-S

CDA Auto Shutdown. Automatically shuts off CDA supply after actual furnace Power OFF to reduce compressor load and gas consumption. Includes timed delay to assure clearing of all process gas and emissions from furnace chamber. Note: furnace control delays actual Power OFF until furnace cools to 100 C.  Option available on most furnaces.
