PTC Top Loading Test Oven The PTC ovens offer high performance in a configuration well-suited for heating long and narrow loads such as tubing and extrusions. The forced-air convected ovens feature horizontal airflow with adjustable louvers to assure uniform airflow even with varying load conditions. Applications include burn-in and qualification testing of downhole electronic logging equipment for the petroleum industry. A space-conscious footprint is combined with removable end caps to allow placement of several ovens of the same model number end-to-end. The marinite end caps may also be machined to insert instruments or tooling. Digital, three-mode PID control allows precise temperature control while a separate high limit control with manual reset provides over-temperature protection. Designed with silicone door seals and positive-latching clamps to hold the door securely in place, the PTC ovens come equipped with a dolly for easy moving. Also available in non-magnectic, non-metallic version and frontloading door option.
