Additional equipment for recoVAIR heat recovery units: dry siphon with connection. 0020180806

Functional condensate drainage in ventilation systems

A key element in maintaining the efficiency of heat recovery ventilation units is the effective and safe removal of condensate generated in the heat exchanger. The solution dedicated to the recoVAIR series is a dry siphon integrated with the connection, which eliminates the risk of backflow of gases or odors from the sewage system into the unit, even in situations where the water in the siphon has completely evaporated. Unlike traditional wet solutions, this model maintains gas tightness without the need to continuously maintain a liquid level, which is particularly important during winter periods or during prolonged interruptions in the operation of the installation.

Application and compatibility with Vaillant units

The device was designed as a direct accessory for selected Vaillant heat recovery unit models. Thanks to a precisely fitted mounting adapter, installation is quick and does not require additional transition elements. The siphon is dedicated for use with the following units:

• recoVAIR VAR 260
• recoVAIR VAR 360

With this solution, the installer receives a ready-made kit that guarantees compatibility with the original heat exchanger housing design. For the end user, this means no risk of incorrect installation and potential leaks resulting from the use of universal, non-fitting accessories.

Construction and operational benefits

The main advantage of this type of siphon is its resistance to drying out. In standard systems, if the unit does not operate for an extended period (e.g., during holidays), the water in a conventional siphon may evaporate, opening the path for unwanted odors or negative pressure into the ventilation ducts. The dry siphon solves this problem mechanically – its construction blocks airflow regardless of the presence of water.

It is worth highlighting several key operational aspects of this solution:

• Ensures system tightness even with a complete absence of water in the siphon chamber, guaranteeing gas safety.
• The included adapter facilitates quick connection to the condensate outlet in the unit, resulting in easy installation.
• Protects the building interior from the penetration of odors from the sewage system or condensate drainage thanks to effective backflow protection.
• Materials used in production are resistant to corrosion and the effects of condensate with varying pH levels, ensuring the device's longevity.

It is important to remember that proper condensate drainage is not only a matter of hygiene but also protection of the unit itself against flooding and damage to electronic components or the thermal insulation of the heat exchanger. Choosing a dedicated accessory from the manufacturer minimizes the risk of installation errors and ensures full functionality of the ventilation system throughout the year of operation.
