               WVM 40 -1450

Transport by crane

  Transport the adsorption dryer in an upright 

position to its location of installation.

Transport by crane

Transport by forklift

  When using a forklift, ensure that the dryer is always in an upright position.

  Secure the dryer with screws to a pallet to ensure that it cannot tilt or fall from the forklift.

Installation and anchoring of the dryer 

  Secure dryer by means of suitable securing devices to the fl oor.

  On oscillating fl oors: The dryer must be positioned on suitable oscillation absorbers. 

Storage

If the dryer is not to be installed immediately after delivery, it must be stored at a suitable 

location that fulfi ls the following requirements:

◊ 

The dryer must not be stored outdoors.

◊ 

The storage room has to be dry.

◊ 

The storage room must be free of dust; otherwise, cover dryer with a tarpaulin.

◊ 

The ambient temperature in the storage room may not be below +1 ºC

To storage the dryer, proceed as follows: 

  Decommission dryer as described on page 36.

  Ensure that the inlet valve and the outlet valve installed on the site are closed and release 

all pressure from the dryer. 

  Make sure that existing steam valves (with optional steam heat exchanger) or cooling 

water valves (with optional loop regeneration) are closed.

  Disconnect dryer from compressed air system.

  Disconnect the plant from the electric mains supply and any external and supply lines.

  Cover the following inlet and outlet openings with fi lm or similar material to protect them 

against contamination by dust and dirt:

— 

inlet and outlet openings for compressed air 

— 

inlet for the regeneration gas at the heater

— 

regeneration gas outlet at the vacuum pump

— 

cooling water intake and exit (with optional loop regeneration)

— 

hot steam intake (with optional steam heat exchanger)

  Cover the dryer with a tarpaulin, if possible..

The dryer is not suitably prepared for prolonged storage.
