  • Single Stage Refrigeration Temperature Range: -35°C to 200°C
  • Performance is based upon an empty chamber operating at 24°C (75°F) 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.
  • Liquid Nitrogen is available as an option on all systems. When Liquid Nitrogen is provided, the heater KW is automatically upgraded to the maximum for that chamber size. Consult factory for current draw of any Liquid Nitrogen 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 –25°C and 100°C. 9 Point: Uniformity measured in accordance with ASTM E145 section 4 at temperatures of –25°C and 100°C.
  • Test chamber performance may be affected by the addition of certain optional accessories.
  • Chamber operation utilizing 50Hz power utility will derate performance approximately 17%
