Very professional team, easy to talk to. We had some specific size requirements and they nailed it. The TP304 stainless tube with aluminum fins works like a charm for heat dissipation. Thumbs up!
As an engineer in Siberia, I tested these fin tubes in extreme cold (-30°C). The ASTM A213 T11 steel performed well with no thermal cracks, and cooling efficiency met expectations (88%). That said, the Russian-language documentation had translation errors in technical terms, causing minor confusion during installation.
No corrosion issues so far, though we're running below dew point carefully. Installation was straightforward—tube sheets lined up, ends clean, rolling into the header went smooth.
