Automatic Vapor Phase Oven

oh I see you put wires in a tube, I thought it was fluid heat exchanger

We are using 500ml Galden at the moment. This isn´t a huge cost factor considering how many cycles you can do with that amount. (and the price of the oven)

The issue is you basically have an unusable amount for technical needs which just stays there as ballast.

The nice thing using immersion heaters especially when they are covered only a few millimeters with medium is, that you can get the galden to locally boil before all the medium is heated above boiling. The convection currents which would transport colder medium to the heater surface can´t develop very well in a relatively thin layer of medium.

It's a wrong type of heater for such effect. Asks for heater used in steam cookers.

you need to decrease the watt density of immersion heaters when used with galden because the thermal conductivity is poor compared to water
