Marc Posted March 19, 2023 Share Posted March 19, 2023 I currently use a 500 liter propane-fired Bain Marie copper alembic for the production of our absinthe (Pacifique Absinthe). We are in the process of upgrading to a larger stainless steel electrically powered Bain Marie still. Currently we are using Clearco silicone oil (PSF-100cSt ) with no issues. My concern is gelling (the copper has a chemical way of preventing gelling). Any recommendations for other heat transfer oils? Steam heating is not an option.

Thatch Posted March 19, 2023 Share Posted March 19, 2023 MobilTherm 43. We have also used G35 heat transfer oil from Lotos. https://lotosoil.pl/upload/oil/import/12624_olej grzewczy G35_ENG.doc.pdf Link to comment Share on other sites More sharing options...

Windy City Posted March 21, 2023 Share Posted March 21, 2023 I see that you said steam is not an option but what about self contained steam? I really like it much more than the oil option. It is clean, very responsive and low maintenance. Check out this thread about converting a direct fired (electric) bain marie to self contained steam Link to comment Share on other sites More sharing options...
Kindred Spirits Posted March 21, 2023 Share Posted March 21, 2023 The one thing to watch out for when converting an oil jacket to low pressure steam, is to make sure that the jacket is rated for pressure. Some oil jacketed stills have no pressure rating so if you were to pressurize them you could end up damaging the equipment or getting someone hurt.

ViolentBlue Posted March 21, 2023 Share Posted March 21, 2023 if you can get 100% bio, Biodiesel (no petro aded) this is fairly inexpensive and is better than standard vegetable oil. Link to comment Share on other sites More sharing options...
Workpress Posted April 21, 2023 Share Posted April 21, 2023 I use old deep fryer oil in my oil jacketed still and it works well, and it is free cheers Workpress Link to comment Share on other sites More sharing options...
