Automatic Air Vents
Automatic Air Vents
(OP)
The closed loop piping network, such as that of chilled water system usually has an Air Separator in the Pump Room. Furthermore, Automatic Air Vents are provided at the highest points (Pipe Risers) to expel air before it even reaches the Air Separator. Sometimes the horizontal piping must be offset upwards to avoid other services and installations. Are Automatic Air Vents essential at these small (one foot high) offsets, or can the water push the air towards the Air Seperator (like it does in open to atmosphere systems such as domestic water supply)?

I've seen air binding in a 6" riser and a 500-ton system had to be shut down to get it out. Vents are inexpensive.

I have been using them for 10 years now and works well as long as there is no debris inside. I made similar comments to that of Compositepro, when I was suggested the first time. You can try and there is no harm
Only thing I don't know is that the traps are expensive than a good automatic air vent valve, atleast not in India.

Plus a manual vent would be a lot smaller and easier to install than the steam trap. Still not sold on the whole idea that using a steam trap in place of an air vent is a good idea.
