OCCASIONAL DEFECT
Coalescent elements saturated by particles and oil preventing the flow
If, for any reason, the evaporation temperature drops too much below
0.0°C, a layer of ice may build up within the heat exchanger, clogging
High pressure loss in the
dryer
Lack of preventive maintenance on the pre-filter. The heat exchanger
may be clogged by contaminants that will settle in its internal cavity.
NOTES:
When there is a pressure drop in the air system, observe the following details:
- If the operation pressure indicated in the display of the Electronic Interface of the compressor is high and at the factory too low, the problem is significant load loss in the air system.
- If the pressure in the compressor is low and in the air system too, it is possible that the consumption increased due to recent installation of equipment. In this case, the required air demand
is higher than the production.
- Before any actions, trying to find the causes in the compressor, close the discharge valve slowly until the pressure rises close to the maximum operating pressure and check the motor current.
- If the compressor is aspiring air at full load and the current is close to the rated current, it is likely the problem is not the compressor.
PROBABLE CAUSE
Filtering element clogged.
of compressed air.
Heat exchanger clogged by formation of ice.
the passage of compressed air.
Heat exchanger clogged by contaminants.
Check the indicator of restriction of the coalescent filters.
If they show restriction, replace them.
With the dryer on and compressed air passing through it,
check if the electronic controller is indicating temperatures
below - 1°C. If so, turn off the equipment and contact a SCHULZ
Keep the air dryer off for 30 minutes with compressed air
(Attention: during this period, the dryer will allow the passage
of humidity to the air system). If at the end of this period, the
load loss persists, the air dryer may be clogged by contami-
nants. In this case, contact a SCHULZ AUTHORIZED DEALER.
