New WINCON 5.0
Besides Windows 7 compatibility, many new features are included in WINCON 5.0 including dual
process capabilities, maintenance manager, and OPC functions. Dual process capabilities increases the
functionality of Pyramax dual lane dual speed systems, allowing speed and rail set point changes on one
lane while the other lane continues to process product maximizing throughput. Equipment maintenance reminders are provided through the maintenance manager function, providing customers a default maintenance plan or allowing them to use their own. The OPC function is an alternative to GEM

subsequent profiles, to overlay and compare different profiles and numerous other improvements.

Features of WINCON:
One step recipe editing simplifies changing of data, and automatic recipe scheduling permits two or
more recipes to be executed at a given time or after a designated event.
Profiling of product temperatures can be automatically sampled at specified times or belt distances.
Collection of data can be triggered by selected events to determine when system variables (temperature, pressure, belt speed, etc.) are to be sampled.
For security purposes operators can be assigned particular access levels for specified user privileges;
Enhanced diagnostics. troubleshooting messages, and remote monitoring capability help to expedite
problem solving.
On-line documentation permits easy viewing of operational and diagnostic data.
Pusher furnaces from BTU are engineered for better heat efficiency and system durability. Alumina
bricking, sophisticated safety controls, and advanced operational software make BTU’s pusher
furnaces ideal for high-performance applications, such as advanced electronics, nuclear fuel pellet
sintering, capacitor manufacturing, metallizing, and calcining. Sophisticated CAD/CAE design capability gives BTU an advantage in responding to a wide range of customer requirements. The design
of BTU’s pusher furnaces optimizes customer productivity while offering maximum flexibility.
Pusher Furnace
Pusher furnaces come in hearth sizes of 6”, 8”, 12”,
and custom widths. Other customization includes
heating and cooling zone configuration, thermal
profiling, and atmosphere control system.
