One of them was a 4" jacketed column with some structured packing inside and I had my hand on it… was a loud bang and the column bounced in my hand. It didn’t leak but the ferrule was turned into a saddle - curved in two directions. When I cut it in half, the outer jacket was at normal size but the inner core column with the packing was a quarter inch thick.
The 6" ones are either loud as hell or completely silent when they deform and you just can’t get the sock out no matter how hard you pull on it.
If you want a system that actually works without failure and to get the training on how & why it works then yeah, you kinda gotta buy from the inventor of the tech. There is definitely more to it than just exchanging heat that is required to make it functional.
It is not like we are up-charging an arm and a leg for the equipment or charging licensing fees to our customers to utilize the tech, even though I spent countless hours trying everything I could think of to get it to actually work as required and built my own c1d1 to test everything in.
We are PSI certified for propane use on all parts of the system.
The columns we supply are designed for making big transitions in temperature in a very short period of time, as well as the expected operational pressures of propane.
For instance, we can go from +50c to -50c in roughly 5 minutes or -50c to +50c in about 2 minutes on the R600 Behemoth.
This thermal shock is very hard on an improperly designed column.
