* NOTE:
Ramp rates are measured at the control sensor after a 2 hour soak at the respective start temperature with
an empty chamber. Measured with setpoint set beyond the start and end temperatures. Ramp rates do not include the
effect of proportional band when approaching setpoint.
Input Power Requirements
230 V ±10%, 60 Hz, 3 PH
Max Current Draw 39 A; Recommended Service 50 A
208 V -5/+10%, 60 Hz, 3 PH

Door latch adds 3" to width on right side, may be removed for move-in.
Min. Installed Clearance
12" from the left and right side, 24" from the rear
Access Ports
4" Port on left and right side (two total), Supplied with foam plugs
Weight
1,200 pounds
Heat of Rejection
27,500 BTUH
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.
