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 (empty): From +85°C to 0°C = 85°C / 7.5 min = 11.3°C/min. Cool Down Example (with 80 lb. load): From +85°C to 0°C = 85°C / 16 min = 5.3°C/min. Heat Up Example (empty): From 0°C to +85°C = 85°C / 13 min = 6.5°C/min. Heat Up Example (with 80 lb. load): From 0°C to +85°C = 85°C / 23 min = 3.7°C/min. *Note: Transition times are measured after a 2 hour soak at the respective start temperature at 208 V input.

Live Load Capacity

4,000 Watts	2,800 Watts	2,300 Watts	1,800 Watts	1,250 Watts

Refrigeration and Heating System
Refrigerant	R-404A (Dupont HP-62)
Compressors	3.5 HP Copeland scroll compressor. More about Scroll Compressors >>
Condenser	Air Cooled
Heater Power	4,000 Watts @ 208 V input

Instrumentation
Temperature Controller	256 step, 40 profile, ramp and soak programmable memory. RS-232/485 interface. More details >>
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
230 V ą10%, 60 Hz, 3 Phase	Max Current Draw 31 A; Recommended Service 40 A
208 V -5/+10%, 60 Hz, 3 Phase	Max Current Draw 26 A; Recommended Service 35 A
	Input may be configured for 230 V or 208 V in the field by changing jumpers. Three phase load is balanced. Call for other voltages or 50 Hz operation. 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	40" W x 34" H x 26" D (20 cubic feet)
Outside Dimensions	49" W x 80" H x 52.5" D (nominal) Door latch adds 3" to width on right side. 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	16" W x 13" H
Access Ports	4" Port on left and right side (two total) Supplied with foam plugs
Weight	Chamber Weight: 1,600 pounds Shipping Weight: 2,000 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.
