HOKUTO MFG Thermo Compressor – Advanced Steam Energy Recovery System

Welcome to Nichiboku's industrial Blog

Introduction

Industrial facilities worldwide rely heavily on steam for heating, processing, and power generation. However, significant steam energy is often lost due to pressure drops, flash steam discharge, or inefficient system layouts. The HOKUTO MFG Thermo Compressor System provides an efficient, reliable solution to recover and reuse this wasted thermal energy. Designed with the precision of Japanese engineering, it supports energy savings, operational optimization, and cost reduction across multiple industries.

What Is a Thermo Compressor System?

A thermo compressor is an energy‑saving device that uses the ejector effect to draw in low‑pressure or flash steam and recompress it into usable medium‑pressure steam. By utilizing high‑pressure steam as the driving source, the system prevents heat loss and enables factories to recover steam energy that would otherwise be wasted.

Key Benefits

  • Reuses low‑pressure or flash steam

  • Converts wasted thermal energy into usable steam

  • Enhances total heat efficiency and system performance

How the Thermo Compressor System Works

The system functions through high‑speed steam dynamics:

Ejector-Based Compression Mechanism

  1. High‑pressure steam accelerates through a nozzle, converting pressure energy into kinetic energy.

  2. The resulting high‑velocity jet creates a negative‑pressure zone that draws in low‑pressure or flash steam.

  3. Both steam flows mix inside the diffuser.

  4. The mixed steam decelerates and is recompressed into medium‑pressure steam for reuse.

This simple, robust mechanism enables continuous operation without moving parts or electrical components.
