Factors to consider when choosing your system n Do you need to immerse samples within a tank? Consider the working area required. The table on p. 2.4 shows the dimensions of the top opening and the min/max liquid depths n Cooling power required at a given temperature For example, if your operating temperature is 0°C, and you need 500 W cooling power, you will need the R4 (or R5) refrigeration unit with any of the controllers. Alternatively to calculate the power required use the following formula: W= n Cool-down time required to reach that temperature W = average cooling power V = total...
