Looking for a 3500w element

I'm already using the 5500w camco ultra low watt density element in my brewery, but now I am making a smaller system for a friend and I'm trying to source a ~3500w element with similar watt density per square inch.

I've been looking at these:

Is the watts per square inch comparable to the 5500w elements most people are using?

 

FWIW....lots of folks use high watt density elements, myself included......camco makes a 3500 watt high density.....I guess lower the better

 

Try this one:

I strongly disagree. I've scorched my beer really badly using hwd 4500w elements. Undrinkable, even for dark beers. Tasted like burn porridge.

 

hmmm...thanks for the feedback, I have only been using the 2000w 120v without issue.

Haven't had any burnt porridge in a while, but lets assume not too tasty
