Expensive heatbands 

SSR, PID, Thermocouple (come often as bundle)

PID/temperature controller : We recommend the Inkbird ITC 100VH since it is keeping the target temperature around +/- 1 degree Celsius and does no overshooting. The REXC – 100 has also auto-tuning but it still overshoots the target by 10 – 20 degree.

VFD (Variable Frequency Drive, enables to run 3 phase motors on single phase)

Motor

we recommend a 3 phase motor with at least 800 watt, as well a 1:30 – 1:50 reducer. Here is a one which works well.
