25 minutes (5°C/minute)
*Note:
Transition times are measured after a 2-hour soak at the respective start temperature with an empty chamber,
as indicated on the temperature controller, 23°C ambient. Measured with setpoint beyond the end temperatures with
an instantaneous step change in Set Point without a controlled ramp-rate. Does not include the effect of proportional
band when approaching setpoint. Performance is reduced by 17% with 50Hz input power.
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
Max Current Draw 35 A; Recommended Service 45 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.
Workspace Dimensions
40" W x 32" H x 36.5" D (27 cubic feet)
Outside Dimensions
49" W x 79.5" H x 67" D (nominal)
Door latch adds 3" to width on right side.
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
Sound Level
68 dBA in cooling mode (A-weighted, measured 36" from the front surface, 63" from
the floor, in a free-standing environment)
Heat of Rejection
27,500 BTUH
Weight
1600 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.
