Re: Condensing pressure control
I will get information about M&M.
Actually, I'd like to find simple PLC from the shelf. Usually, it is much cheaper than custom made PLC. It should have two set points of the condensing pressure. One for operation and one for defrosting. Additionally, sequence of the fans and pumps should be chosen. I ask one company in our region but their cheapest PLC is $30,000. We know how to ave energy but we need tools(not expensive) to implement that knowledge.
