KEY DESCRIPTION
CMB30 Forced Air Cooling Module. Supplies fan-driven ambient air for rapid convection cooling of product on the belt. This
76.2 cm (30 inch) long, forced air cooling module uses two top-mounted cross-flow 13.3 m
3
/min (471 cfm) fans to
force ambient air into a plenum assembly located above the belt, resulting in a downward laminar flow over the entire
surface area of the belt directly under the cooling module. Controlled atmosphere processes should be reviewed to
assure that the product is below its oxidation temperature before reaching the air cooling. Fan speed is controlled via
the control console.
Multiple modules may be joined to obtain required cooling. Standard on some furnace
configurations, option available on most furnaces.
CMB45 Forced Air Cooling Module. Supplies fan-driven ambient air for rapid convection cooling of product on the belt. This
1.143 m (45 inch) long, forced air cooling module shall use three top-mounted cross-flow 13.3 m
3
/min (471 cfm) fans
to force ambient air into a plenum assembly located above the belt, resulting in a downward laminar flow over the
entire surface area of the belt directly under the cooling module. Controlled atmosphere processes should be
reviewed to assure that the product is below its oxidation temperature before reaching the air cooling. Fan speed is
controlled via the control console.
Multiple modules may be joined to obtain required cooling. Standard on some
furnace configurations, option available on most furnaces.
CWWC Cold Wall Water Cooling Module. High efficiency, 50.8 cm (20 inch) long, water-cooled module that improves heat
transfer from cooling tunnel, more rapidly reducing the temperature of the product. Includes OI integrated inlet and
outlet water temperature sensors and alarms. Requires water supply and drain. Multiple modules may be joined to
obtain required cooling. Upgrade from CACT.
Standard on some furnace configurations, option available on most
furnaces.
DOCM Furnace Owner’s Manual. Installation, startup operating, and troubleshooting instructions for a specific furnace.
Includes specific customer drawings, schematics and engineering calculations. Standard on all furnaces.
DOCR Furnace Reference Manual. Continuous Belt IR Furnace Reference Manual including information on IR furnace
nomenclature, thermal processing; furnace control and software; maintenance, troubleshooting and calibration; and
process engineering.
Standard on all furnaces.
EME Entrance Emergency Machine Off, Vertical Mount. Two (2) SEMI approved 40 mm diameter emergency shutoff
buttons are located on either side of the entrance on the vertical face of the furnace approximately 1.27 m (50 inches)
above grade.
Standard on all furnaces.
EMX Exit Emergency Machine Off, Vertical Mount. Two (2) SEMI approved 40 mm diameter emergency shutoff buttons
are located on either side of the exit on the vertical face of the furnace approximately 1.27 m (50 inches) above grade.
Standard on all furnaces.
ENG English Units of Measure or US customary units . Furnace control software shall depict belt speed in inches per
minute (in/min), gas flow in standard cubic feet per hour (scfh). Temperature units shall be degrees Celcius (°C).
Standard on all furnaces unless SI is selected at time of order.
ETM Elapsed Time Meter. Adds a mechanical meter to keep track of the cumulative time the furnace is ON. Standard on
all furnaces.
FM Independent Zone Flow Control. Process Gas is controlled by variable rate flowmeters enclosed behind a clear
panel. Panel access can be restricted by one of three methods: Keyed lock, mechanical latch or fastened by screws
(lock and latch shall both be provided). Atmosphere shall be controlled by manually adjustment of the flowmeters.
Standard on all furnaces.
IE Intermediate Exhaust Eductor. An exhaust stack with eductor that is located between selected chambers to
increase control of process gas flow, to promote isolation of specific furnace chambers and to evacuate volatile
emissions off-gassed from product.
Standard on some furnaces.
LOAD Load Station. The load station is an area 381 mm long (15 inch) at the entrance of the furnace which provides open
access to accommodate loading of product on the continuous belt for processing by the furnace. Standard on all
furnaces.
LTR Left to Right: Belt moves from left to right as viewed from the operator console. This is the default furnace
configuration. Standard on all furnaces if RTL is not specified with original order.
OI Operator Interface. Operator Interface also known as MMI (man machine interface), and HMI (human machine
interface). OI refers to the furnace graphical display software that the operator uses to communicate with the furnace
PLC and to observe data collected by the Furnace PLC.
Furnace graphical interface software that allow the user to view and modify furnace operating parameters and
communicate with the PLC.
Standard on most furnaces.
OIT Operator Interface Terminal. Furnace computer with OI , OIT refers to the furnace computer that the operator uses
to communicate changes to the furnace PLC and to observe data collected by the Furnace PLC.
Furnace computer and monitor are wired to stay “ON”, regardless of control panel ON/OFF pushbuttons, as long as
power is supplied to furnace. This arrangement allows reliable startup and shutdown of the furnace computer, allows
use of the furnace computer without powering up the furnace, and extends furnace computer life and reliability.
Standard on most furnaces.
OSXP XP Operating System. Microsoft WindowsXP™ operating system on the OIT .
