Product Overview
Compact Graham Heat Exchanger, Helifow 12X6C-12
Condition:
We believe this heat exchanger has likely never been used, but since we cannot verify this, we are selling it as used. The internals look quite clean, and it is in good cosmetic condition, with some scuffs and scratches that appear to be from storage without packaging.
The Graham Heliflow Heat Exchanger is a uniquely designed and highly efficient heat transfer solution. The Heliflow 12X6C-12 model is a specific variant of this innovative technology.
Design and Construction
The Heliflow Heat Exchanger features a spiral coil of multiple parallel tubes mounted within a casing. This design creates a spiral flow path that provides true counterflow, resulting in superior heat transfer efficiency. The coiled construction allows for compact sizing and the ability to handle high pressures and temperature extremes.
Key Features
- High Efficiency: The Heliflow design can achieve heat transfer rates up to 40% better than typical shell and tube designs.
- Compact Size: Its spiral design allows it to fit in locations where other heat exchangers might struggle.
- Easy Maintenance: The casing can be removed for cleaning without disturbing pipe connections.
- Versatility: Suitable for a wide range of applications and industries.
Applications
Graham Heliflow heat exchangers are typically in various applications, including:
- Liquid-to-liquid heat transfer
- Mechanical seal cooling
- Compressor inter/aftercooling
- Hot water heating
- Cryogenic cooling and vaporizing
- Supercritical fluid processing
- VOC emission reduction
Performance
The Heliflow design maximizes thermal efficiency through its 100% countercurrent flow pattern. It's engineered to balance thermal and hydraulic requirements for optimal heat transfer in each application.
Advantages
- Reduced fouling tendencies
- Ability to handle thermal expansion and shock
- No gasket compatibility issues
- Customizable coil spacing to optimize velocities
- Compliance with various industry standards (ASME, PED, etc.)
