8.1.1 Basic information about cleaning heat exchangers
Fins require cleaning to ensure that the heat exchanger continues to operate at full
capacity.
• Use a brush (not wire brush) or an industrial vacuum cleaner for this purpose.
• Do not use hard or sharp cleaning tools!
• Use compressed air stream against airflow direction or water spray at low pressure
to clean copper or aluminum fins.
• Use steam-jet appliances to clean steel galvanized heat exchangers or heat
exchangers with reinforced fins.
Injuries caused by sharp edges!
Observe precaution when cleaning due to risk of cuts on thin and sharp edges.
• Wear chemical resistant gloves.
ATTENTION
Risk of damage to the unit!
• During commissioning, avoid one-sided pressure loads outside the design
parameters – otherwise the fins might be damaged.
In this case, DencoHappel neither accepts warranty claims nor assumes liability.
