14.2 - Description
14.2.1 - Fixed-speed pump
This pump is factory-fitted as standard to guarantee nominal flow
in the water loop. It is a fixed-speed pump with available system
pressure. See the pump flow/pressure curves in chapters 8 and
9.
The system's nominal flow rate must be adjusted with a manual
control valve provided by the customer (see chapters 10 and 11
on controlling the nominal water flow rate).
The maximum permitted concentration of the glycol additives
(ethylene glycol or propylene glycol) is 35%.
The maximum pump suction pressure is limited to 400 kPa (4
bar) due to the valve installed the pipe that carries the water to
the unit.
The use of any other glycol type additives must be approved by
the manufacturer.
Use of hydraulic module in an open loop is
forbidden.
14.2.2 - Variable-speed pump
This pump is factory-fitted. It is a variable-speed pump with
available system pressure. See the pump flow/pressure curve.
The system flow rate is automatically adjusted via the frequency
converter built into the pump, based on the heat rejection load
on the drycooler.
The maximum permitted concentration of the glycol additives is
35%.
The maximum pump suction pressure is limited to 400k Pa (4
bar) due to the valve installed the pipe that carries the water to
the unit.
The use of any other glycol type additives must be approved by
the manufacturer.
Use of hydraulic module in an open loop is
forbidden.
