Hi Everyone,
I am about to complete a panel that controls 2) 12kW 480VAC Tank Heaters. Thanks to everyone that helped me on my previous thread about designing of the panels. I have designed the panels to use Crydom SSR's for the control.
I have never done a tank heating application so I am looking for some opinions on how to best control the temp. I was planning on using a simple ON/OFF control scheme. I need to maintain the tank at about 85-90 Deg. F The tanks is a 30k Gallon steel tank and is not insulated. It is in a semi cold environment. Winter lows around 20 F.
My Question is: Is it better to have a narrow band of ON/OFF Temps and maybe be able to use one heater at a time to maintain the temp or is it better to have a wide band of ON/OFF Temps and use both heaters to heat the tank?
Just looking for ideas as I start the PLC program from someone that may have done this kind of thing before.
Thanks for the help!!
