Water degassing

Water degassing

The piping network of a greenhouse heating system is never completely diffusion tight. Regardless of the amount of pressure on the pipe, oxygen molecules will penetrate. To keep this as low as possible and thus extend the life of the heating hoses, degassing is important. This is how we prevent oxidation in the heating system. 

The colder the water in the heating pipes, the more oxygen will be absorbed. Around 0°C a maximum amount of oxygen is found in the water, while around 104°C your water will be completely oxygen free. By means of a degasser, we lower the pressure in the system, which lowers the boiling point of the water and removes the oxygen from the water. 

Continuous degasser

Water that has been degassed goes back into the heating system. This oxygen-deficient water mixes with oxygen-rich water, which reduces the oxygen content in the entire heating system. 

By means of the continuous degasser, we ensure that the moment of oxygen degassing and the starting of the vacuum pump is very short, so that we actually degas continuously. This offers the advantage of degasifying the boiler water in a considerably shorter time. 

Extending the lifespan of the heating system

Through this continuous degassing of tap water, we extend the life of the heating system in the greenhouse considerably. Due to the lower oxygen values in the water, we prevent oxidation in the heating system.
