Cool Down Transition Time*
Start Temp	End Temp
Start Temp	+23°C	0°C	-40°C	-55°C	-65°C	-73°C
+23°C	-----	4 min	18 min	25 min	33 min	Ultimate
+50°C	5 min	11 min	27 min	36 min	45 min	Ultimate
+85°C	13 min	20 min	37 min	47 min	55 min	Ultimate
+150°C	32 min	39 min	58 min	65 min	76 min	Ultimate

Heat Up Transition Time*
Start Temp	End Temp
Start Temp	+23°C	+50°C	+85°C	+125°C	+150°C	+175°C
+23°C	-----	1.5 min	7 min	14 min	20 min	25 min
0°C	1.5 min	3.5 min	13 min	20 min	23 min	31 min
-40°C	6 min	11 min	17 min	24 min	30 min	35 min
-55°C	8 min	13 min	19 min	26 min	32 min	37 min
-65°C	10 min	14 min	21 min	28 min	34 min	39 min

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, 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. Performance is reduced by 17% with 50 Hz input power.

Live Load Capacity

Refrigeration and Heating System
High Stage Refrigerant	R-404A (Dupont HP-62)
Low Stage Refrigerant	R-508B (Dupont SUVA-95)
Compressors	1.5 HP x 1.5 HP Tecumseh hermetic compressors in a cascade configuration.
Condenser	Air Cooled
Heat of Rejection	14,800 BTUH (maximum rated chamber load at maximum cooling rate from high temperature soak)
Heater Power	2,000 Watts
Air Flow	450 cfm

Instrumentation
Temperature Controller	Watlow F4T Touch Screen Controller with RS-232, Ethernet interface, 4.3" color graphic touch screen. OR... Watlow F4 Controller with RS-232 interface, LED readout of temperature, LCD display of other parameters.
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
230 V ±10%, 60 Hz	3 PH	19 A	25 A

208 V -5/+10%, 60 Hz	1 PH	28 A	35 A
208 V -5/+10%, 60 Hz	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. Performance is reduced by 17% with 50 Hz input power.

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

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.
