Ljungström®
Plate HX

Efficient. Leak-Free. Modular.

Robust, modular and all-welded with no leakage between flows, Ljungström® Plate HX efficiently preheats combustion air for fired heaters, furnaces, boilers, waste heat recovery, thermal oxidation systems, dryers, kilns and other high-temperature industrial processes.

Flue gas cooling and waste heat recovery

Capturing waste energy to lower the cost of carbon capture

Built for the Real Challenges of Heat Recovery

Where Reliability Matters Most.

Industrial heat recovery systems operate under demanding conditions, where reliability often matters more than theoretical performance. Ljungström® Plate HX is an all-welded plate heat exchanger designed for reliable performance in demanding industrial environments.

No Leakage

No Moving Parts

all-welded, open-flow design

3 Flow Options

cross-flow, counter-flow and multi-pass

Modular

ships fully assembled for easy installation

Operators must balance:

Space limitations

in existing facilities

Fouling

from dirty gas streams

Pressure drop

within tight system constraints

Maintenance windows

that are often limited

Cost efficiency

heat recovery that protects profit

These realities, not efficiency alone, drive equipment decisions.

Key Capabilities

A modular, all-welded heat exchanger built for long-term reliability, maintainability and lifecycle flexibility.

Leakage Control by Design

Fully welded construction with no leakage between air and gas flows.

Mechanical Simplicity

Simple, robust design with fewer failure points and reduced downtime.

Optimized Thermal Performance

High effectiveness and low pressure drop support performance within tight operating constraints.

Designed for Harsh Gas Conditions

Engineered to handle particulate-laden and fouling gas streams in demanding industrial service.

Maintenance-Friendly Operation

Online soot blowing and offline water washing help maintain performance over time.

Application-Specific Configuration

Plate geometry, spacing and flow arrangement are tailored to specific process requirements.

Flexible Installation Options

Cross-flow, counter-flow and multi-pass arrangements for a range of industrial applications.

Material Selection for Service Demands

Carbon steel, stainless steel, specialty alloys and porcelain enamel, depending on operating conditions.

How It Works

Design & Flow

  • Flat plate cores in a robust structural casing form alternating air and gas passages
  • Guiding vanes ensure even flow distribution
  • Cross-flow, counter-flow and multi-pass configurations

Materials & Customization

  • Plate thickness, spacing and geometry tailored to the application
  • Carbon steel, stainless steel and specialty alloys
  • Porcelain enamel available to meet service demands

Easy Installation & Low-Maintenance Operation

Ready to install, built to stay clean.

Ships Fully Assembled

Compact, modular construction for flexible layouts and easy field erection.

Optional Features

Removable modules for improved serviceability, plus air by-pass systems.

Reduced Fouling

The flat plate, open-flow design reduces fouling, with online soot blowing or offline water washing when extra cleaning is needed.
