SE
Maximize performance with the Alfa Laval SE brazed heat exchanger range–where ‘S’ stands for safety and ‘E’ for efficiency. Engineered with safety in mind, this premier range offers enhanced strength and minimal refrigerant charge. The advanced plate design boosts efficiency, delivering superior heat transfer using less natural refrigerant 290. Ideal for next-generation heat pumps and chillers, the SE range optimizes sustainability in heating and cooling, outperforming previous models.
For safety and efficiency
- Optimized for natural refrigerants to support the transition to more sustainable energy solutions
- Enhanced safety due to up to 40% lower hold-up volumes and additional mechanical safety margin
- Increased efficiency, thank to a highly asymmetric design and integrated distribution system
- Greater energy savings, especially in heating duties, due to condensing temperatures reduced by 1 to 2K
- Easy to install in new or retrofit existing chiller or heat pump installations since SE footprint
Minimize your carbon footprint and achieve higher thermal efficiency with the Alfa Laval SE range. Custom-built from standard modules, it is ideal for indoor and outdoor HVAC and refrigeration applications in residential and commercial settings.
Optimized plates with an innovative distribution system ensure a low refrigerant charge while meeting all safety requirements. Reduced hold-up volumes and Alfa Laval IceSafe technology enhance reliability and extend equipment lifespan.
The SE range uses fewer plates to achieve the same thermal efficiency as using more of our previous plates, due to an innovative design and distribution system. Stronger, responsibly sourced stainless steel plates reduce energy use and the SE’s carbon footprint to support the transition to net zero.

DynaStatic
Flexible refrigerant distribution
This breakthrough production method lets you fully tailor the placement, size and number of inlets to fit your specific application, ensuring the optimal refrigerant distribution system for your products. The result is higher efficiency with the flexibility to use low-GWP refrigerants.
PressureSecure
Unparalleled strength for demanding duties
Our innovative plate designs support the widest range of high-temperature and high-pressure applications. Units can run using thinner plates and fewer plates, which translates to less raw material, lower energy consumption, reduced refrigerant charge and a longer equipment lifecycle.
FlexFlow™
Superior thermal performance
Alfa Laval’s patented asymmetrical plate design is one of many unique innovations that gives you improved thermal efficiency thanks to optimized pressure drop and increased turbulence. In addition to cutting energy consumption, that means reducing refrigerant volumes and raw materials.
IceSafe
Controlled, non-destructive freezing
For applications that require it, we can supply plate heat exchangers designed to allow ice crystals to form under certain operating conditions, but displaced from sensitive areas. This ensures both reliable performance and a long product life.
REFuture
