PLATE & BLOCK

HEAT EXCHANGER-Fully Welded. Compact. Reliable & Efficient.

What is a Plate Block Heat Exchanger?
A Plate Block Heat Exchanger is a fully welded plate-type exchanger. It consists of corrugated metal plates welded together to form a compact block, with no gaskets, and enclosed in a pressure-retaining shell.

Advantage:
- No gaskets – suitable for high temperature and pressure ( up to 400Co , and up to 40 bar)
- Handles corrosive media
- Compact with high thermal efficiency
- Low maintenance and leak risk
- Well-suited for phase-change duties (NH3)
Available Material:
-304 / 316L stainelss
-SMO
-C276/C22
-TI ( Grade 1, Grade 2)
