*Note:
Transition times are measured after a 2 hour soak at the respective start temperature with an empty chamber,
at the control sensor as indicated on the temperature controller, at a 23°C ambient. Measured with the temperature
controller set beyond the end temperatures. Does not include the effect of proportional band when approaching the
temperature set point.
To calculate rate of change for a particular condition, take the difference between the Start
Temp and End Temp and divide by the Transition Time.
Cool Down Example (empty):
From +85°C to -40°C = 125°C / 28 min = 4.46°C/min.
Heat Up Example (empty):
From -40°C to +85°C = 125°C / 17 min = 7.35°C/min.
Input Power Requirements
230 V ±10%, 60 Hz, 3 PH

NOTE:
Performance is typical and based on operation at 23°C (73°F) ambient and nominal input voltage. This
product is designed for use in a normal conditioned laboratory. Operation at higher ambient temperatures may result
in decreased cooling performance. Additional ports and shelves will also affect performance. Operation above 30°C
(85°F) or below 16°C (60°F) ambient is not recommended.
