Transporting Dryer To Its Location Of Installation - Parker Zander WVM Series Operating Manual

Transporting dryer to its location of installation

Requirements regarding the location of installation
The general conditions at the site of installation greatly affect the operation of the
dryer and the service life of the desiccant. In order to ensure long-lasting
operation with minimum maintenance, the location of installation must meet the
following requirements:
Weather protection

The location for installation must be weatherproof and inside a building.
Protect the dryer against moisture. Read the notes on page 22 when the
dryer is to be installed outside (option). When installed outside, the dryer
must be insulated.
Ambient air

The ambient air must be as free from dust as possible since heavily dust-
laden installation locations reduce the drying agent's service life. In case of
doubt we recommend to supply the dryer with regeneration gas by way of
supply ducts or pipes. For this purpose, a special heating pipe or a heating
pipe adapter can be used for retrofitting.
Ambient temperature

The ambient temperature must not be below +1° C. Implement an additional
heating if necessary (see page 22). In this context please also heed the
information regarding insulation on the following page.

If possible, the ambient temperature should not exceed 30° C and the relative
humidity not exceed 60% in order to ensure sufficiently effective regeneration
and a suitable pressure dew point. A higher ambient temperature or relative
humidity must be specially considered when designing the dryer and
recorded in the offer document if this proves to be unfeasible. If the required
cooling water is available, you should implement the optional loop cooler.

Please also heed the appropriate notes in section Technical data!
Ventilation

Provide sufficient ventilation as moisture is released to the ambient air during
regeneration.
Note:
Guide the regeneration gas from the vacuum pump out of the
installation room using exhaust ducts or pipes. Please follow the
notes on page 31 regarding the installation of the supply line.
Criteria for insulation
The dryer must be insulated if one or all of the following criteria are met:

When the room temperature at the installation location drops below 10° C for
more than 1 hour per day.

When the room temperature at the installation location drops below 15° C for
more than 3 hours per day.
