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 +85C to -10C = 95C / 14 min = 6.8C/min.
Cool Down Example (with 25 lb. load): From +85C to -10C = 95C / 22 min = 4.3C/min.
Heat Up Example: From -35C to +85C = 120C / 16 min = 7.5C/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.

Refrigeration and Heating System

Refrigerant R-404A (Dupont HP62)
Compressors 1.5 HP Tecumseh hermetic
Condenser Air Cooled
Heat of Rejection 15,200 BTUH (maximum rated chamber load at maximum cooling rate from high temperature soak)
Heater Power 2,000 Watts


Temperature Controller

Watlow F4 Controller with RS-232 interface, LED readout of temperature, LCD display of other parameters (standard).
Watlow F4T Touch Screen Controller with RS-232, Ethernet interface, 4.3" color graphic touch screen (optional).

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, 1 PH Max Current Draw 22 A; Recommended Service 30 A
208 V -5/+10%, 60 Hz, 1 PH Max Current Draw 22 A; Recommended Service 30 A

Input may be configured for 230 V or 208 V in the field by changing jumpers. Single phase input only. 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.

Outside Dimensions* 33" W x 68.75" 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 13.375" W x 9 " H
Access Ports 4" Port on left and right side (two total)
Supplied with foam plugs
Weight Chamber Weight: 785 pounds
Shipping Weight: 910 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 23C (73F) 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 30C (85F) or below 16C (60F) ambient is not recommended.
