Thread: Prawn Trawler Refrig Regas

Link to the article would be good.......... As far as your yacht goes, all depends on charge qty and future leaks developing doesn't it, are the systems DC hermetic or open drive from Aux engine, is there a chance the refrigerant could leak and accumulate in the bilge? If no leaks down the track should be no problem.

I remember seeing a 4 CYL Perkins destroy itself from ingesting R12 years ago............shudder to think what would have happened if it was a propane based refrigerant

You asleep out there Ean?

Our eutectic system in the yacht was R 12 but we had a propane stove and oven.
I imagine you have too so Hychill in the reefer should not be any more of a problem.
Put a gas detector in the bilge or if still concerned contact Hychill direct. I found them very helpful.
I put it in the Rangie and its all good, and I will put it in the RedDot in the disco as soon as these adaptors for these bloody R-134a fittings arrive.

I know there are 3 or 4 different gases being trialled. R22 is being phased out so the price reflects that. It is used because you can achieve very cold temps with it.
My understanding is a lot of things need to be changed when changing from R22. Expansion valves need replacing and believe even a certain type of oil is needed with the new gases.

What was used in your yacht? Think you need to find that out before you go much further.

I will speak with our fleet engineer and see what they are trialling in the fleet.

Cheers Ean

Thanks to all sorry no good with links My yacht comprises two separate systems 1/ a engine or electric driven open Bock compressor.The other a semi sealed unit which I would be happy enough using Hychill but not so sure about the Bock .The gas alarm has 2 sensors but evacuating the bilge would be a bit nerve racking in the event of a leak As the system is new any suitable gas would be OK .The fridge is separate again

Thanks Noel

Try the new drop in replacement for R22 called SP22. I sell a lot of it and it works very well. You can top up existing R22 systems, retrofit systems to a full charge of SP22 (80% of R22 charge) as it runs on POE and mineral oils and it is about 1/3rd of the price of R22. Best of all, it don't go bang like a hydrocarbon

Sounds good but with all the licence hassles I guess

Yes, you will need an arctick licence to purchase
