*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 -30°C = 115°C / 19 min = 6.0°C/min.
Heat Up Example (empty):
From -30°C to +85°C = 115°C / 15 min = 7.5°C/min.
Input Power Requirements
230 V ±10%, 60 Hz, 3 PH
Max Current Draw 31 A; Recommended Service 40 A
208 V -5/+10%, 60 Hz, 3 PH
Max Current Draw 16 A; Recommended Service 35 A
Input may be configured for nominal 208 V or 230 V in the field by changing jumpers.
Call for other voltages or 50 Hz operation.

67 dBA in cooling mode (A-weighted, measured 36" from the front surface, 63" from
the floor, in a free-standing environment)
Heat of Rejection
30,200 BTUH (maximum rated chamber load at maximum cooling rate from high
temperature soak)
Weight
1,410 pounds
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.
