Condensate – the arch-enemy of ventilation
Condensation is a natural physical phenomenon that occurs when warm air cools down to the dew point temperature. Condensate can form in the ventilation system, especially in areas where there is a large temperature difference, such as in bathrooms or kitchens.
Causes of Condensate Formation in Ventilation Systems
Different Air Temperatures: The air temperature in the room can be significantly higher than the air temperature in the ventilation system. If the temperature difference is too large, moisture from the air can condense.
Air Humidity: Humidity is also an important factor that contributes to condensate formation. The more humid the air, the more likely it is that condensate will form.
Insufficient Ventilation Insulation: Proper insulation of the ventilation system helps reduce the temperature difference between the room air and the air in the ventilation system. If the insulation is inadequate, condensation can occur.
Preventing Condensate Formation in Ventilation Systems
Reduce Air Temperature Differences: If possible, reduce the temperature difference between the room and the ventilation system.
Lower Humidity: If the air in the room is too humid, use a dehumidifier to reduce the moisture.
Insulate the Ventilation System: Ensure the ventilation system is insulated to prevent external cooling.
Prevent Cold Air from Entering the Ventilation System: You can prevent cold air from entering the system from the outside by using our PZKD Anti-Odor Damper. (It is important to consider the fan’s performance and the damper's sealing to ensure everything works properly).
Condensate Collectors
HACO offers a wide range of condensate collectors suitable for various applications. HACO condensate collectors are made of high-quality materials and can be installed in both flat and round pipes. All HACO condensate collectors have a drain to direct the condensate away from the ventilation system.
Where and How to Install a Condensate Collector?
The collector should be placed in the lowest point where temperature changes occur or, ideally, in the lowest part of the ventilation system above the fan. Typically, this is just above the ceiling in an unheated attic.
The condensate collector can be installed both vertically and horizontally. However, it is crucial to maintain at least a minimal slope leading to the drainage part of the collector.
Joints must be sealed with silicone or aluminum tape.

Condensation in the ventilation system can cause several problems, such as blockages, mold and bacteria growth, or unpleasant odors. We recommend installing a condensate collector with drainage in every ventilation system where condensation might occur.
