I do not understand what you mean by equipment? I use 2 plastic lunch boxes for my developer tank and etchant tank, then sit them in a bucket of hot water to speed up the etching time. IF the equipment you mean is for this, then it is easy to get.

What I suggest is using pentel-pen or masking tape for the trace you want to retain for your circuit. Then Ferric chloride will remove the exposed copper.

Quite useful and impressive info. I have learned a lot from your article and I will keep on reading your sharing.
