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 main-
tenance, 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 18 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 retrofi tting
Ambient temperature:
◊ The ambient temperature must not be below +1° C. Implement an additional heating if nec-
essary (see page 18). 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 suffi ciently 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 suffi cient ventilation as moisture is released to the ambient air during regeneration.
Note:
Guide the regenera¬tion gas from the vacuum pump out of the installation
room using exhaust ducts or pipes. Please follow the notes on page 26 re-
garding 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.
◊ In case of draught at the installation location as can be expected with ventilation systems,
passages or similar. This applies regardless of the room temperature. Measure the draught
fl ow rate in the vicinity of the dryer when you are in doubt. Insulate the dryer if the fl ow rate
exceeds 0.3 m/s in the immediate vicinity of the dryer.
◊ When a pressure dew point exceeding –40° C is to be supplied.
The dryer can fi rst be delivered without insulation. Retrofi t an insulation if the desired pres-
sure dew point cannot be attained due to the above criteria
