PLC Precise Pillow Plate Heat Exchangers
High heat recovery rate and long service life for industrial applications
Product Overview
Precision temperature control pillow plate heat exchanger designed for maximum heat recovery efficiency and extended operational lifespan. Available in multiple material options to suit various media characteristics:
- 304/316L stainless steel for conventional working conditions
- Hastelloy and titanium for acid and alkali resistant media
- Nickel-based alloys for high temperature and high pressure scenarios
Plate thickness is customized according to pressure levels (0.5-3mm) with fully automated welding process ensuring stable operation under extreme conditions from -196℃ to 350℃, strong corrosion, and high viscosity environments.
Product Introduction
As a core component of Jiangsu Ruiding's catalytic incineration systems, this plate heat exchanger handles exhaust gases containing propylene, propane, formaldehyde, acetaldehyde, acrolein, acetic acid, and acrylic acid on the cold side, while managing hot flue gas from catalytic reactions on the hot side.
With catalyst sensitivity to temperature variations, this preheater maintains temperature stability within ±2℃ of design specifications, ensuring optimal reaction efficiency.

Key Advantages
High Temperature Efficiency and Stability
Heat load capacity of 3930 kW handles large exhaust gas flows (63,935 Nm³/h cold side) with 382℃ inlet temperature differential. S30408 stainless steel construction provides high temperature resistance (505℃) and corrosion resistance against organic acids like acrylic acid.
Precise Temperature Control for Catalyst Protection
Cold side temperature increases from 123℃ to 280℃ while maintaining catalytic reaction temperature fluctuations within ±2℃, ensuring optimal catalyst activity and reaction efficiency.
Adaptability to Complex Media
Designed to handle corrosive components including acrylic acid and formaldehyde with anti-blocking plate design that reduces coking risks.
