ThermFlex High-Efficiency Pillow Plate Heat Exchanger®
Compact, Reliable, and High-Performance Heat Exchange Solution





The ThermFlex Pillow High-Efficiency Heat Exchanger® is a groundbreaking solution for efficient heat transfer, engineered to meet the demands of modern industries. With its high-pressure resistance, exceptional stability, outstanding heat transfer performance, and compact structure, it offers a space-saving design ideal for a wide range of applications, including inlet and outlet heat exchangers, condensers, and evaporators.
How it Works
The ThermFlex heat exchanger uses a unique pillow-shaped heat transfer element that maximizes efficiency on both sides of the heat exchange process. Its design enables:
- Precise heat conduction between the reactor’s inlet and outlet materials, raising the temperature of raw materials at the inlet while cooling the products at the outlet.
- Effective utilization of waste heat to save energy and reduce emissions, ensuring sustainable operation.
Key Benefits of ThermFlex Pillow High-Efficiency Heat Exchanger®
- Low Energy Consumption:
- Achieves minimal pressure drops on both sides, thanks to adjustable plate spacing and height.
- Shell pressure drop can be as low as 0.05 kPa under certain conditions.
- High Pressure and Versatility:
- Handles pressure differentials exceeding 100 bar.
- Supports negative pressure and vacuum conditions.
- Cost-Effective and Space-Saving:
- Compact structure reduces footprint and simplifies installation, transportation, and pipeline arrangement.
- Flexible form sizes and efficient heat transfer reduce the need for multiple units, lowering investment costs.
- Advanced Functionality:
- On-line cleaning capabilities for ease of maintenance.
- Permeable shell channels allow small amounts of catalyst powder to pass through.
- Single unit coverage up to 10,000 m².
- Sustainable Operation:
- Promotes energy conservation, emissions reduction, and reduced operational costs.
Applications and Working Conditions
Ideal for:
- Gas-to-gas and gas-liquid heat exchange.
- Partial or full condensation processes.
- Evaporation applications.
Typical Applications Include:
- Hydrogenation inlet and outlet heat exchangers.
- Carbonylation, methanol, and PX inlet and outlet exchangers.
- Catalytic cracking inlet and outlet exchangers.
- Phenol-acetone, cyclohexanone, and glycol overhead condensers.
