Engineered for critical fluids & gases – combining safety and efficiency
About
SIGMADUAL Semi Welded Plate Heat Exchangers offer a unique hybrid design where a gasketed plate is precisely welded to a second plate, creating modules of 2 plates.
This makes them ideal for processes involving critical, corrosive, or hazardous fluids and gases where compatibility with gaskets raises an issue.
Applications & Benefits
Semi welded PHEs are perfectly suited for demanding environments such as:
- Ammonia refrigeration and cooling
- Oleum and Decene processing
- Geothermal applications
- Chemical production with aggressive or toxic media
- High-pressure steam and condensate recovery
- Thermal oil and refrigerant applications
Their half-welded construction ensures fluid separation from gaskets, minimizing leakage risk while still allowing routine gasket replacement and service.
Key Features
- Plates fully welded in the fluid path to avoid gasket contact
- Classic frame allows easy maintenance and inspection
- High pressure and temperature resistance
- Designed for aggressive, toxic, or hazardous fluids
- Compact footprint with high heat transfer efficiency
- Compliant with international industrial and safety standards
Sustainability in Action
SIGMADUAL exchangers provide:
- Enhanced process safety and leak prevention
- Optimized heat recovery to reduce energy waste
- Longevity and reliability in harsh conditions
- Alignment with environmental reporting and sustainability targets
- Support for circular thermal systems and reduced carbon footprint
