1.6.2 Ambient Laboratory Temperature
Distek recommends that the laboratory temperature control system be kept on at all times.
Maximum Conditions:
To achieve the full range of controlled operation (20 to 65°C) within specified tolerances, the
Model 2500 Series Dissolution System is designed to be installed and operated in laboratories
where the maximum operating temperature does not exceed 25°C. The maximum allowable
ambient operation temperature is 30°C.
Operating environments above 25°C limit the range for satisfactory operation of the system to
between 20°C and 65°C.
Minimum Conditions:
To assure controlled operation within specified tolerances, the Model 2500 Series is designed to
be operated in laboratories where minimum operating temperatures do not drop below 20°C.
Variability or Short Term Fluctuations:
To assure controlled operation within specified tolerances, the system used to control the
temperature of the laboratory where the Model 2500 Series Dissolution System is installed must
be able to maintain the ambient air temperature within ±2.5°C of set point (worst case).
Thermal Loading:
Each unit contributes an average thermal load of about 0.6 kW when operating. The lab’s cooling
systems must have sufficient excess cooling capacity to handle the aggregate thermal load for all
systems installed. The heating system must also be able to respond to the increased loading from
the units by appropriately throttling back.
For laboratories where temperature control is critical, installation of several dissolution units
may require that the system be re-balanced. Thermostats may need to be relocated to
maintain temperature uniformity inside the laboratory.
