This is what I have done to the rack system bought from Louis.
1) Upon delivery the new rack system was put onto wheels.
2) The heat cable was rerouted to have most heat inside the tub area
3) Switches were added to enable to switch levels off if not in use. The white switch is where the controller probe is.
4) A controller was added and the best place was in the base of the system, holes was drilled and covered for ventilation.
5) A circuit breaker was installed to provide extra protection to the electrical components.
A 3 pole contactor is use to take the load of the controller. The ratio that I used is 4/3/3.
Meaning L1 of the contactor is feeding the first 4 levels of the rack, L2 the next 3 levels and L3 the last 3 levels.
6) The next step was to find an idea to lock and secure each tub. I have played around with various ideas and decided on this one
Making “doors” one for each tub.
7) Hasp & Staples are use for locking and just for extra touch a card holder was added.
8) Finely “The occupant”
Thanks for looking
