Cooling rates are approximate and represent the average rate achieved over the stated
temperature range with an empty chamber. Actual cooling rate achieved may vary depending on
the temperature range, the type of cooling, the pressure of the gas, and other factors.
Additionally, all cooling rates stated are for the condition when the controller is not cycling the gas
flow. The controller will slow the rate of cooling as the temperature nears set-point, so as to not
overshoot the set-point.
