Re: Helo friends
It rather depends on the gas return speed that you require.
Download Coolpack calculation program to help with your calcluations.

Or Danven from Danfoss. It's free.
It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.
