Shift SupervisorWe swapped out our old clunker for this Plate Air Preheater six months ago, and the improvement in thermal efficiency is no joke. The burner flame is way more stable now, and I'm not constantly chasing draft readings. Even the night crew noticed the difference in how fast the boiler ramps up. Solid piece of kit for a mid-sized plant like ours.
Raj_K
Senior Process EngineerInstalled this on a retrofit project for a cement kiln waste heat recovery loop. The compact design saved us about 18 inches of ductwork real estate, which was huge given the tight space constraints. Only took off one star because the gasket kit wasn't included in the initial shipment, but the unit itself handles the particulate-laden gas stream better than I expected. Would spec again.

Maintenance Tech IIII'm the guy who has to clean the thing, so I was dreading another finicky design. But this one? The lane spacing is generous enough that I can actually get the soot blower lance in there without playing Tetris. We've been running heavy fuel oil for two weeks straight and the pressure drop is still within spec. My back thanks you.

Facilities ManagerWe're a food processing plant, so we run 24/7 during harvest season. Downtime is a four-letter word. This preheater has been online for nine months with zero unplanned outages. The only hiccup was a slight vibration issue on startup that a field service tech sorted in an afternoon. For the price point and the fuel savings we're seeing, it's a win.
