Temperature-Controlled Process EquipmentPrecision ovens & thermal equipment

For a quotation, provide wet-load mass, moisture or solvent type, container depth and batch endpoint; ask the supplier to state gauge units and pump configuration. Check sample and tray contact with heated surfaces. Heat transfer changes at low pressure, so the sample core can still be warming after the controller reaches setpoint.

Low oxygen and low moisture are separate endpoints: an acceptable chamber oxygen reading does not prove acceptable electrode moisture, so include post-drying transfer and packaging in trials. Define the oxygen sampling location, analyser delay and calibration method. Test with a real load and after door opening; supply-gas purity cannot substitute for chamber oxygen measurements.

Compare oxygen-reduction curves at the same load and sampling location, including hold, cooling and recovery after door opening, rather than comparing only minimum oxygen readings. Define the oxygen sampling location, analyser delay and calibration method. Test with a real load and after door opening; supply-gas purity cannot substitute for chamber oxygen measurements.

For a 600°C process, request usable-workspace, loaded temperature-spread and over-temperature protection records at the target temperature, and confirm conditions for unloading after cooling. Place sensors for the thermal load of parts, fixtures and trays; record ramp overshoot, stable hold and cooling. Use an empty-chamber curve only as a baseline.
