CAUTION
The performance of the dryer (dew point, power consumption, pressure drops, etc.) depends mainly on the flow rate and pressure of the
compressed gas to be dried and on the condenser cooling fluid temperature (ambient temperature).
These data, which are usually defined at the time of the offer, constitute the basic point of reference in relation to dryer performance.
