Sanitising a CFC without a pump?

[aamcle]

After another PID Auto-Tune issue I'm thinking of trying a batch without recirculation.

I cool my wort with a 30ft CFC it is easy to sanitise using the pump I just recirculate through it for 10 minutes or so.

I've tried draining the kettle under gravity through the pump (without the pump running) into the CFC and I can go straight to pitching temperature.

If I'm not going to recirculate the pump seems an over complication so I'd like to drain the kettle under gravity through the CFC without a pump in the system.

What I don't know how to do is sanitise the CFC without recirculating through it.

If I were to boil up a couple of gallons of water and just let that drain through would that be sufficient?
I know I can't use StarSan to sanitise the CFC as it chews on the copper pipe but is there something else I could use that would do the job?

Many thanks . aamcle

Could you run a gallon or two of hot wort through the CFC without running chiller water, return the runnings to the hot kettle, then proceed to chill as usual?

Heat sanitize it first, then chill.

I fill mine with StarSan by attaching tubing and filling a funnel until it is flowing freely and plug both ends. I let it sit while I'm brewing then flush out by blowing through tubing on the inlet.

Boil it in a big pot for 15 minutes the night before. Then just spot sanitize the connections.

Drain the wort through without the cooling water until it comes out at about 200F. Return that drained wort back into the kettle. Run the coolant water and then run the wort through into your fermenter.

I wouldn't rely on chemical sanitizing on a CFC or plate chiller. Heat is the only way to be sure.
