Yes, it is a closed system. That was one thing that I relly looked for. I have a closed system on my Volvo 140 and it is absolutley worth ever dime. There was a drain plug in the exchanger (V 20) to get rid of the raw water. I removed this plug and installed a peacock valve off of an airplane engine. Works great.
