- Performance is based upon an empty chamber operating
at 24C (75F) ambient air and may vary slightly at other ambient temperatures. Voltages
below those listed may affect performance. All performance data is for 240
or 480V / 60Hz operation.
- LN2 is available as an option on all systems. When LN2 is
provided, the heater Kw is automatically upgraded to the maximum for that chamber size.
Consult factory for current draw of any LN2 equipped chambers.
- Airflow circulation is based on blower wheel
performance curves. Actual circulation rate will vary depending on the cooling
option selected.
- Temperature uniformity Standard deviation from the mean, measured at –25C and
100C. 9 Point: Uniformity measured in accordance with ASTM E145
section 4 at temperatures of –25C and 100C.
- Test chamber performance may be affected by the addition of
certain optional accessories.
- 17% Performance reduction will be observed on 50Hz Model
- It is Tenney ’s policy to constantly improve quality,
features and performance. Tenney reserves the right to change specifications without
notice.
