*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 start and end
temperatures. Does not include the effect of proportional band when approaching setpoint.
Input Power 120 V nominal (110 to 126 VAC), 60 Hz, 1 PH
Max Current Draw 18 A, Recommended Minimum Service 20 A (dedicated line)
Workspace Dimensions 18" W x 16.5" H x 13.5" D (2.3 cubic feet)
Outside Dimensions 26" W x 63" H x 36.5" D (nominal). Vent tube adds 3" to height.
Min. Installed Clearance
6" from the left and right side, 12" from the rear
Access Ports 4" Port on left and right side (two total), Supplied with foam plugs
Sound Level 58 dBA (A-weighted, measured 36" from the front)
Weight 750 pounds
NOTE: Performance is typical and based on operation at 23°C (73°F) ambient and nominal input voltage. 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.
Due to continuous product development, specifications are subject to change without notice.
