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.

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.
