Requirements to the installation area
It is very important that enough space around the plate type heat exchanger is kept free for servicing of the unit (renewal of plates, tightening of the plate package).
As a rule the free space around the unit should be 1, 5 to 2 x the width of the unit.
Transport, lifting and storage
Usually the heat exchanger will be supplied horizontally on a pallet. The back side of the head will then be tightened to the pallet. This allows you to transport the unit by means of a fork lift truck.
Rising of the unit:
• Remove all tightening elements from the pallet;
• Place straps around one bolt on each side as shown on the picture. Never use steel cables or chains!
• Lift the heat exchanger from the pallet;
• Lower the heat exchanger slowly to vertical and on it’s feet and place it in it’s end position on the floor.
• Remove the straps and tighten the heat exchanger to the floor.
ALWAYS: Use the lifting eyes (if fitted)
Lift the top side of the head
Attach the straps to the bolts close to the head
Should it be necessary to store the heat exchanger for a longer period (1 month or more), certain precautions should be taken in order to prevent unnecessary damage to the equipment.
Preferably the heat exchanger should be stored inside in a room with a temperature around 15 to 20 ºC and a humidity of max. 70%. If this is not possible, place the heat exchanger in a wooden box which is provided with a lining on the inside against penetration of moisture.
There should absolutely not be any ozone producing equipment in the room, like electric motors or arc-welding equipment, since ozone destroys many rubber materials. Also do not store organic solvents or acids in the room and avoid heat or ultraviolet radiation.
NEVER: Lift using the connections Lift the follower
Lift using an intermediate plate
Lift with a strap attached close to the follower
Installing the pipe connections
We advise you of the following:
• Heavy pipe work needs to be supported. This will prevent heavy forces on the heat exchanger.
• Always install flexible connections on the follower to prevent vibrations on the heat exchanger. These flexible connections also prevent expansion of the pipe work, caused by temperature influence, onto the heat exchanger.
• These flexible connections need to be fitted in a longitudinal direction to the plate package.
• The pipe work needs to be thoroughly cleaned and flushed before connecting up to the heat exchanger.
• Always install vents on both sides of the heat exchanger.
Note: For proper venting the vents should be fitted on the highest point in the direction of the flow of the medium (preferably on an air vessel).
To enable the heat exchanger to be opened when necessary shut off valves should be provided in all connections!
Threaded pipe connections:
If a plate type heat exchanger is provided with threaded pipe connections, make sure that these connections do not rotate when fitting to the pipe work. It could damage the gasket on the start plate. You need to make “counterhold” on the connection!
If the connection is rubber lined, the liner will act as the flange gasket. Bolt the connecting flange directly to the endplate using the drilled and tapped holes provided. Tighten the bolts evenly – do not over-tighten as this could strip the threads cut into the frame plate.
If loose backing flanges are fitted to the heat exchanger a suitable gasket is required to seal the flange.
Unless otherwise stated, the liquid circuits should be connected to flow in reverse directions through the exchanger (counter-current). Refer to the contract drawing or quotation details if the connections are not marked.
