Tab. 10-1 Temperature classes
For the compression of ideal gases, the maximum expected temperature can be
calculated using the formula for adiabatic status change:
The isentropic exponent κ can be found in the corresponding tables for common
gases.
Since the compression takes place as part of the heat exchange with the environ-
ment, the actual temperature will always be below the calculated temperature.
Consider the full range of operating conditions. A drop in the primary pressure p
A
leads, for example, to an increase in the maximum expected temperature T
B
The gas booster should not be insulated. If it is insulated, the equipment manu-
facturer must determine the temperature class of the equipment accordingly.
10.3 Operation and maintenance
Static electricity on the product can lead to explosions. This may result in severe
or fatal injuries.
Never use high-power mechanisms for charge generation on or near the product.
In order to ensure adequate safety during regular operation and in the event of
foreseeable errors, the function of the gas booster and compliance with the
thresholds specified in these instructions must be monitored accordingly.
In doing so, the maintenance activities must be carried out at intervals that are
appropriate for the application.
For safe operation, the devices may no longer be used after the leakage thresh-
olds have been exceeded.
