8.1.2
Water pressure
For a reliable operation a water flow rate of
• 7 l/min to 8 l/min (at 10 kW)
• 14 l/min to 16 l/min (at 20 kW)
is required. Normally, 2 bar primary pressure at the entrance of the absorber are sufficient in case of an un-
pressurized outflow.
NOTICE
Damage/Destruction of the device due to overpressure
X
The maximum permissible water inlet pressure must not exceed 4 bar.
8.1.3
Humidity
• The device must not be operated in a condensing atmosphere. The humidity has to be considered in
order to prevent condensates within and outside the device.
• The temperature of the cooling water must not be lower than the dew point (see Tab. 8.1 on page 29).
NOTICE
Damage/Destruction of the device due to condensing water
Condensation water inside of the objective will lead to damage.
X
Mind the dew-point in Tab. 8.1 on page 29.
Do only cool the device during the measuring operation. We recommend starting the cooling approx. 2 min-
utes before the measurement and terminating it approx. 1 minute after the measurement.
