W01, Heat Exchanger Module, partially redundant with 2 pumps

Availability of option
This option is available for the following S120 Cabinet Modules:
● Heat Exchanger Modules
Description
The Heat Exchanger Module is equipped with a pump and a plate-type heat exchanger as
standard.
With option W01 two redundant pumps with two dirt traps and two non-return valves are
installed in the system.
The pumps, which operate alternating, pump the hot coolant of the internal deionized water
circuit into the plate-type heat exchanger and there is cooled by the raw water of the plant-
side cooling circuit.
System reliability is increased as a result of the alternating operation of the redundant
pumps. The time in hours can be parameterized.
In addition, the dirt traps can be cleaned independently and during operation, as shutoff
valves are installed before and after the individual pumps.
Note
Increased cabinet width and cabinet weight
With option W01, the cabinet width increases to 1000 mm.
With option W01, the cabinet weight increases by approximately 110 kg.
9.50 W10, insulation of the pipes in the raw water circuit and heat
exchanger
Availability of option
This option is available for the following S120 Cabinet Modules:
● Heat Exchanger Modules
Description
With this option, the pipes in the raw water circuit and the pipes of the heat exchanger are
insulated. This means that if the raw water on the plant side is too cold, condensation does
not occur on the pipes and liquid does not collect in the Heat Exchanger Module.
