Water Filter
Many closed loop water chillers come with an inline water filter. If this is the case, no
additional filter is needed. However, if the water source is not filtered, then the water
must be filtered with a conventional inline particulate filter. The filter must be on the
inlet side of the cooling manifold. The filter protects against a build-up of debris in the
manifold and cooling pipes, and most importantly, avoids potential jamming of the flow
turbine blades. Small particles can get between the housing and blade tips and stop the
turbine. If this happens, the laser
will fault. It may become necessary to remove the
outlet hose connected to the flow turbine and gently rotate the turbine blades with a
paperclip to resolve a stuck turbine. The turbine will not jam if the water is within
specification and is filtered.
Setting the Flow Rate
The 1625 measures the flow rate and will fault if the value is too low (not enough
cooling) or too high (exceeding rated water pressure). The water flow rate can be
monitored by connecting to the RS232 and running a special software package
available from Iradion. Alternatively, the water flow rate can be set with an external flow
meter. The use of a flow bypass valve can help control the flow rate from aggressive
chillers.
