Sondersiphon pressure side with stench trap  item No. 100500

The pressure side AquaKlima-Sondersiphon serves as drainage of HVAC units in wet areas in accordance with the terms of the air-conditioning techology.

The accruing condensation accumulates in a base tub then will run through a drain connection in the over pressure siphon (drain trap).Prior to commissioning, the siphon (drain trap) should be filled with water and be checked and cleaned through the sealing cap at regular intervals.

These over pressure siphon are also equipped with a consisting sealing ball, which

will be lifted up in the situation of an increasing water column. This enables the condensation to drain freely. The main advantage is that the ball can consistently close the pressure side siphon. As a result, the evaporation of the condensation will be prevented and the siphon will be functional for a longer period. Under dry conditions, the venting of air will be limited due to the sealing of the tube by the ball and therefore in non operating conditions, the ball forms a consistent seal.

Each air or ventilation device which produces over pressure must be equipped with a Sondersiphon to ensure trouble-free operation.

To each drainage outlet a Sondersiphon should be installed separately so it can slow down freely (hygiene).

The Sondersiphon is produced from non-organic polypropylene and is resistant to frost and heat, not frost proof. This you can achieve with the help of our Siphon-trace heating.

Technical information:

The standard delivery version is designed for 2,200 Pascal max. In case of marginal over pressure, the extension pipe or the bend can be shortened or the siphon can be placed in a sloping position (See adjoining measurement table). A safety factor of 1.5 has been taken into account in our measurement table, to adjust pressure fluctuations within the system.

The immersion tube can be lengthened in case of higher over pressure. They are available from stock.
