Chapter 1: Introduction
Operation Manual: Evolution Series
Minimum Conditions:
To assure controlled operation within specified tolerances, the Evolution
System is designed to be operated in laboratories where minimum operating
temperatures do not drop below 15°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 Evolution System is
installed must be able to maintain the ambient air temperature within ±2.5°C
of set point (worst case).
Thermal Loading:
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 in the
lab.
1. 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.
2. The heating system must also be able to respond to the increased loading
from the units by appropriately throttling back.
Ambient Laboratory Humidity
Distek recommends that the laboratory humidity control
system fans be kept on at all times if possible. This
should result in better set point control and reduce the
short term excursion range.
Maximum:
The Evolution System may add to the humidity of the laboratory during
operation. The bathless design (6100 only) reduces humidity compared to
other models, but any vessels filled and left uncovered can raise humidity
levels. Water vapor and/or hydrogen chloride vapor, from dissolution media,
can cause serious effects when condensed on electrical components and
contacts. The lab’s environmental controls should maintain the humidity
level below the dew point, to minimize the risk of condensation.
