u PTC Non-Magnetic Oven

For burn-in and qualifi cation testing of
down-hole electronic logging equipment

 e PTC ovens off er high performance in a con guration well suited for
burn-in and quali cation testing of down-hole logging equipment.  e
forced-air convected ovens feature vertical down air ow with adjustable
louvers to assure uniform air ow even with varying load conditions.

A space-conscious footprint is combined with removable end caps to
allow placement of several ovens end-to-end.  e marinite end caps may
also be machined to insert instruments or tooling. A digital, three-mode
PID control allows precise temperature control while a separate high limit
control with manual reset provides over-temperature protection.

 is design features non-magnetic/non-conductive workspace
construction. Silicone door seals and positive-latching clamps to hold the
door securely in place.

Small Footprint – e PTC ovens are

designed with fans and controls located
below the work chamber to minimize oor
space, which is at a premium in the eld
oces where the ovens are most commonly
used.

Performance – Louvers for uniform airow.

Reliability/Repeatability – Consistent,

repeatable performance in a small package.
Rugged designs for long term reliability,
units are low maintenance.
