Start-up device
A start-up device basically consists of a pressure holding device, which is located
at the rear of the dryer. The pressure holding device ensures that pressure can
build up in the dryer and adsorption take place.
It is always required when an empty compressed air reservoir or an empty
compressed air system must be filled downstream of the dryer (e.g. following
weekend shutdowns and when the pressure in the compressed air system can
frequently drop below the stated operating pressure).
Outside installation
As standard, the dryer is not suitable for outside installation, as its function and
service life is influenced by the following factors:
Environmental humidity due to rain (or other deposit)
Corrosion caused by environmental humidity or a salt-containing environment
Freezing of valves, cocks, flaps, and other components at low temperatures
Therefore, a planned outside installation must always be discussed in advance
with the manufacturer to allow specific technical design measures to be provided
for the installation location.
Auxiliary heater
For installation sites with temperatures under +1 ºC, the wet side of the dryer
must be equipped with an auxiliary heater to prevent valves, cocks, flaps, and
other components from freezing up.
Bypass line
The bypass line is a "detour line", which allows the compressed air system to
continue operating even whilst maintenance of the dryer is in progress. However,
during this time the air is not dried but flows through the bypass line past the
dryer and through to the actual loads.
