3.8. Higher pressure pump
The standard Vario-Line units are designed with a 3 bar pump, which is designed to the nominal
flow rate of the respective unit. Optionally, the units can also be supplied with higher pressure
pumps within the minimum or maximum flow rate limits. The pump characteristic of the pump(s)
used in your unit is enclosed with the unit.
3.9. Speed-controlled pump
On request the Vario-Line units can also be supplied with a speed-controlled pump. The delivery
head and the delivery rate are adjusted automatically to the system characteristic of the overall
system. This means that the pump output can be adjusted to a minimum and the power
consumption reduced.
3.10. Additional evaporator pump
The evaporator is optimised for the nominal flow rate of cold water. The nominal flow rate is listed
in
Table 3: Technical specifications . If the operating flow rate of the cold water is more than 50 %
lower an evaporator pump must be installed. The evaporator pump circulates the cold water
internally and keeps the stored water at flow temperature. A second pump supplies the process
circuit with cold water.
3.11. Second load pump
The standard Vario-Line units are designed with a 3 bar pump, which is designed to the nominal
flow rate of the respective unit. If a second load with the same liquid and same liquid temperature
but different liquid quantity or different flow pressure is to be supplied, the unit can also be
optionally supplied with a second load pump.
3.12. Second temperature level
If several loads with the same liquid but with different temperature levels are to be supplied, a
second setpoint can be specified for the secondary circuit. In this case an additional temperature
sensor records the temperature in the secondary circuit. A control valve adds a partial flow rate of
the primary circuit until the required setpoint is reached in the secondary circuit.
3.13. Second medium
If several loads with different liquids are to be supplied, an optional second tank, which is filled with
a different medium to the primary circuit, can be provided. Both circuits are separated from each
other hydraulically by an additional plate heat exchanger. Similar to the above-named option, a
control valve adds a partial flow rate of the primary circuit until the required setpoint is reached in
the secondary circuit.
