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 -10°C = 95°C / 14
min = 6.8°C/min.
Cool Down Example (with 25 lb. load): From +85°C to -10°C
= 95°C / 22 min = 4.3°C/min.
Heat Up Example: From -35°C to +85°C = 120°C / 16 min = 7.5°C/min.
*Note:
Transition times are measured after a 2 hour soak at the respective
start temperature.

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.
