A fan will also generate heat in in enclosed insulated fridge and it also keeps the area even in temperature. I run a 2 glass door drinks fridge for fermenting and with one 16watt fan running continuously it requires cooling in winter. The less efficient the fan the more heat it will produce.
You could Get a second dip tube installed in the top plate for taking samples from about 1/2 way up, you will near always pull yeast and trub of the bottom within a few inches during fermentation, I'm not certain but it may have an effect on gravity readings, as you said once cold crashed it...
Check there is no delay/anti cycle timers set, not familiar with this controller but others have default 3 min delays. Indicator symbol may flash when its timing out.
I was quoted over $500 for a sheet of perforated stainless for the same type of project (newcastle area) I ended up
Getting a stainless fab shop to laser cut 2600 perforations at 2 x10 mm the smallest they could do, it is 600mm dia and was under $300. Materials and cutting
Not the best option but If it's being drunk within a couple of days you could go with a hand bike pump. As long as it has not lost to much carbonation already.
I was just going to degas the head space lift the lid tip the dry hops in then seal it up. Worked out you can push co2 through the dip tube to give it all a bit of a stir up and raise back up to desired pressure. If degassed fairly slowly foaming should not be an issue.
Any else find the spunding valves keg king sell a bit of a pain to set. Tried my first pressure ferment on the weekend seem to keep having to adjust the valve to maintain the same pressure.Ended up just removing it and using a blow off tube. May look at a solonoid and pressure control option...
Yes I find to get best results is to get max temp diff,as the plate chillers are so efficient u can utilise the whole exchanger and have a high flow of product if your inlet temp is low enough.
I have a plan to convert a heat pump hws into a chilled water tank for this purpose.
Just need to...
Pre chill the go, you can even submerged the whole pre plate chiller in the slurry while recirculating. The commercial lancer font chillers are designed that way.
Hi moad
Regarding the ice water for recirculating I found best to run tap water through a spare immersion chiller in a large tub of ice slurry and then to the wort chiller then to waste. You will be surprised how much ice u go through. I chill down 60 lts of water in a drum in the fridge day...
