Monitoring dryer operation
Notes on specifi c operating situations
Parallel operation of several plants
The standard confi guration comprises one compressor and one dryer. Please contact the
manufacturer if you plan a plant differing from this confi guration.
Part-load dryer operation
The dryer provides optimum performance at high loads. This is the case if the operating
parameters match or slightly fall below the specifi ed values.
Dryer performance can degrade if the dryer often operates at part-load. Dryer performance
increases as soon as the load is raised.
Part-load operation can occur
◊ due to too low fl ow rates (< 30 % of rated value),
◊ by operating the plant with predried air (i.e. the relative humidity of supply compressed air
is below 30% RH),
◊ due to an operating pressure that is higher than the rated pressure,
◊ due to a compressed air temperature that is much lower than the rated temperature,
◊ if several of the above conditions apply.
