Cold trap on NH3
Hi, do ice traps work on ammonia systems for removing water? Water ends up in the coldest part of the system so if you made a colder part would the water migrate there? Cheers.

I suggest installing an H.A. Phillips Anhydrator System Cleaner. It basically traps contaminants such as water. You can get information on how it works on their website

Re: Cold trap on NH3
We are cheapskates, we have a spare ammonia portable vessel.
Fill if up 50 %, let it vent naturally back into system.
Do that a number of times, drain water off, check amount.
Keep doing that until no water left.
Get client to keep filling, over a few weeks or so should get less & less. MJust need a suitable spare ammonia vessel.

What works well is an oil trap under a Low Pressure Receiver. Vent it off as RANGER1 suggests.
I had a system years ago that split a oil cooler for a Vilter piston machine. We found a lot of the water eventually ended up in the Intercooler.

Re: Cold trap on NH3
Thanks all. I have experience with the above methods and I’m a cheapskate too hence wanting to try the cold trap. I’ll see if the client is keen for me to give it a go and I will report back.
