0°C 1.5 min 3.5 min 13 min 20 min 23 min Ultimate
-40°C 6 min 11 min 17 min 24 min 30 min Ultimate
-55°C 8 min 13 min 19 min 26 min 32 min Ultimate

Rate Of Change

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: From +50°C to -40°C = 90°C / 27 min = 3.33°C/min.
Heat Up Example: From -40°C to +50°C = 90°C / 11 min = 8.18°C/min.

*Note: Transition times are measured after a 2 hour soak at the respective start temperature with an empty chamber.

Limit Controller Independent high and low temperature limits. Triggers an audible alarm and shuts down the chamber. Relay contacts provide a safety power interlock for test sample.
Chart Recorder   (Optional) Honeywell DR4300 Series. One pen, 10" circular chart. Mounts in lower front door.

Input Power Requirements

  Phase Current Draw Minimum Service
230 V ±10%, 60 Hz 1 PH 25 A 30 A
3 PH 19 A 25 A
 
208 V -5/+10%, 60 Hz 1 PH 28 A 35 A
3 PH 21 A 30 A

Input may be configured for single or three phase in the field by changing jumpers. Three phase load is semi-balanced. Call for 50 Hz operation. Cooling performance is reduced 17% at 50 Hz.

Customer power source must be hard-wired to the chamber by a qualified electrician. Power cord and plug is not included.


Physical Characteristics

Inside Dimensions

24" W x 21" H x 24" D (7 cubic feet)

Outside Dimensions* 33" W x 67.75" H x 54.25" D (nominal)
* Door latch adds 3" to width on right side (may be removed to permit move-in through a 36" doorway). Circulator motor and housing adds 6" to height.
Minimum Installed Clearance 18" from the left and right side
24" from the rear
Window Viewing Area 13.5" W x 11.5" H
Access Ports 4" Port on left and right side (two total)
Supplied with foam plugs
Weight Chamber Weight: 850 pounds
Shipping Weight: 1,000 pounds
Sound Level 62 dBA in cooling mode (A-weighted, measured 36" from the front or side surface, 63" from the floor, in a free-standing environment)

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.
