Chapter 5 – Frequently Asked Questions
Why does my chamber heat or cool slower than the published specifications?
Performance is significantly affected by the characteristics of your test sample. Factors include
size, weight, material, shape, and power dissipation if energized. The test sample should be
placed in the chamber in a manner that allows for air circulation. Multiple test samples should be
distributed throughout the chamber to ensure even airflow and minimize temperature gradients.
If necessary, an additional shelf should be used to evenly distribute the load. You can determine
if the chamber is operating properly by following the procedure in “How to verify the chamber
performance”.
How can I modify the chamber to cool faster or colder?
Unfortunately, there is nothing you can do to improve upon the designed-in performance.
Modifying the chamber will permanently damage the chamber and void the warranty.
Why is there water coming out of the tube in the back of the chamber?
Under what conditions do I need to be concerned about condensation?
Any time the ambient air is subjected to temperatures below the dew point, moisture will
condense out of the air. For example, if the room temperature is 23°C (74°F) and the room
humidity is
≥
45%RH, moisture will condense if the chamber is held at 10°C (51°F). If the room
temperature is 23°C (74°F) and the room
humidity is ≥59%RH, moisture will condense if the
chamber is held at 15°C (58°F). The condensate drain is provided to remove condensate from the
chamber.
Under most controlled laboratory or office conditions, there will be no condensation.
My test specification requires convection heat only. Can I turn the circulator motors off?
NO! This will damage the thermoelectric devices and void the warranty. You need a “gravity
convection oven” for that kind of test.
