Application Examples

Smooth Tube Exchanger

Used in highly contaminated environments (e.g. animal farms). Built without fins and with thicker tubes (≥0.5 mm) for reliability.

Tinned Copper Exchanger

Made with copper tubes and fins, tinned for marine use. Ideal for coastal, offshore, and naval platforms. Frames in galvanized steel or brass.

Channel Cooling Exchanger

Equipped with a condensation collection tray—differentiates from heating-only models.

Channel Heating Exchanger

Used for naval post-heating. Features copper tubes, stainless steel (304/316) frame, and protective guards on bends and headers.

E-Coated Exchanger

Designed for aggressive atmospheres like curing rooms (e.g. cheese, meat) where ammonia is present. C5-class protection.
