Steam-to-Water Heat Exchange Unit (Industrial Grade)

High-Pressure Hybrid Solution

This industrial unit features a hybrid thermal design to overcome the heat limits of standard plate gaskets. By integrating a Shell-and-Tube Heat Exchanger as the primary stage, high-temperature steam is pre-cooled before entering the Plate Heat Exchanger. This configuration combines the extreme durability of tube exchangers with the high efficiency and compact footprint of plate technology, ensuring maximum system safety and longevity.

Water-to-Water Heat Exchange Unit (Standard Type)

High-Efficiency Liquid-to-Liquid Thermal Solution

Designed for optimal liquid-to-liquid heat transfer, this unit leverages the core advantages of Plate Heat Exchanger (PHE) technology: superior thermal efficiency, a compact structural footprint, and simplified maintenance. It provides a reliable and energy-efficient solution for municipal district heating, residential HVAC systems, and industrial cooling processes.

Precision Thermal Components for Industrial Applications

Hybrid steam-to-water heat exchanger combining shell-and-tube and plate technology.

Integrated Steam-to-Water Exchanger

Our flagship hybrid unit integrates a shell-and-tube stage above a plate exchanger. High-temperature steam first passes through the tube section to safely drop pressure and temperature, protecting the plate section. This combines tube durability with unmatched plate efficiency.

Precision Thermal Components for Industrial Applications
