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 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.

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
| 230 V ±10%, 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. |

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