Like New 2015 TP Solar TF-618 Thick Film Processing Infrared Furnace

Newly manufactured in 2015 for a special project, this furnace features the TP Solar split casing design which allows the top of the heating chamber to be raised above the chamber bottom by wired remote while the furnace is down for maintenance.

This 1000C 18-inch belt furnace was designed for low oxygen processing with a 3-port sampling system and built-in Illinois Instruments EC-913 analyzer system for sampling furnace chamber gas. One extra port is provided for use of a auxiliary analyzer.  

Connect up to 3 process gases simultaneously. The PLC control system is designed for computer switching between combinations of CDA, Nitrogen and Forming Gas* (FG<4.5% Hydrogen). Furnace chamber has 2" clearance height above the 18" wide belt. Heating chamber is 4-zone, 60 inches long. The furnace has 90 inches of water cooling followed by fan cooling section.  The furnace chamber has 4 quartz ports in the top of each zone for a IR temperature measureing devices.
