All standard models (except LA-306 series and “P” models) include a RAID1 computer with LCD  screen, full size keyboard interface
and both Ethernet and wireless-N high-speed network connections to facilitate view
and control of the furnace by managers and process engineers from any location.
Four (4) local USB ports are provided, convenient for connecting a furnace profiler and jump drive storage devices.

The new “P” series replaces the computer control system with high quality discrete digital controllers
for cost-effective precision control on repetitive production applications.
These furnaces are a good solution in applications where process recipes are changed infrequently and auxiliaries are at a minimum.
