Start with the tube and heated length
A tube furnace chamber must fit the process tube, deliver the required heated zone and integrate with the enclosure, insulation, terminals and control system. Split construction may support installation around an existing tube, while other configurations are qualified around the furnace architecture.
TubeMaterial, outside diameter, wall and operating orientation.
ZoneTotal heated length, number of zones and temperature profile objective.
OpeningsSplit line, ports, thermocouple route and end insulation.
ElectricalSupply, resistance or power target, terminals and controller interface.
Replacement measurement checklist
- Process-tube outside diameter and required clearance
- Overall chamber and heated-zone lengths
- Outside dimensions and enclosure interface
- Split orientation, hinge or fastening arrangement
- Element and terminal photographs
- Available drawings and electrical data
