Plate type heat exchangers
Plate type heat exchangers are typically made of aluminium. Their service life is virtually unlimited. Maintenance is
limited to cleaning operations.

• Clean the condensate drain pan, check the siphon and fill up as necessary.
• Any accumulation of fibres or dust on the exchanger may be removed with a hair broom or vacuum cleaner.
Discharge
• Any oil or greasy deposits must be removed. Make sure the bypass damper (if any) is operating properly.
If a bypass damper is fitted, maintain as suggested in above Dampers section.
