Summary

Product identification

The product is a Tubular Heat Exchanger of type ‘THEXA’, designed for medium pressure applications.

Introduction

This heat exchanger is intended for fluid-to-fluid heat transfer (cooling or heating). It is constructed from EN.1.4404 (AISI 316L) stainless steel with a sanitary surface finish.

Inner surface roughness: ≤ 0.8 µm
Outer surface roughness: ≤ 1.6 µm

All fluid media used must be compatible with EN.1.4404 (AISI 316L) Stainless Steel.

Operating limits

The THEXA heat exchangers described are designed for a maximum product side pressure of 40 BAR[g].

The shell side maximum pressure and temperature limits vary with heat exchanger size and are based on maximum allowed steam pressure:

0.5 m² and 1 m²: 10 bar[g] / 185°C
2 m²: 8 bar[g] / 176°C
3 m²: 6 bar[g] / 165°C
4 m² and 6 m²: 3 bar[g] / 144°C
8 m²: 2.3 bar[g] / 136°C

For pressure and temperature limits with fluids other than steam, consult the "Heat exchangers – pressure and temperature relations" document.

Group specifications
