COMPACT BLOCK

WELDED HEAT EXCHANGER-Handling Heat, Pressure, and Corrosion — All in One Block
What is Compat bloc HEX?

COMPAT BLOC HEX features a fully welded block-type structure composed of laser-welded corrugated plates enclosed within a rigid steel shell. The plate pack forms a series of alternating channels for two media to flow in cross-flow or counterflow configurations, ensuring high thermal efficiency.

Our plate pack blocks has an open channel across the entire width of the plates ensuring the free flow of the working medium at the inlet (without stagnant zones) and efficient heat exchanger flushing. In other manufacturers' designs, the edges of the plate pack are blocked at the inlet or part of the plate is cut, which reduces the heat exchange area.
