A Packinox heat exchanger is ideal for demanding heat recovery duties in processes with high pressures and temperatures. Its outstanding thermal performance, superior hydraulic efficiency and low CAPEX allow you to optimize energy efficiency, increase profitability and improve sustainability. A Packinox enables higher yield and recovers more heat than a shell-and-tube solution, resulting in better ROI and a lower environmental impact. Packinox is also available as plate-and-frame configuration.

Reliable efficiency

  • Lower OPEX – The high heat recovery leads to substantial energy savings. Maintenance costs are also low thanks to minimal fouling.
  • Lower CAPEX – A single Packinox can replace several large shell-and-tubes and makes it possible to operate processes with smaller furnaces and cooling
  • Higher process yield thanks to a low pressure drop, optimal liquid/gas mixing, high operating flexibility and a fully customized design.
  • Reliable, proven technology – More than 350 units in operation worldwide.
  • Real-time monitoring and continuous optimization by Alfa Laval experts.

Packinox plate-and-frame heat exchanger

The plate-and-frame version of Alfa Laval Packinox has no pressure shell and no Spray Bar system. It is suitable for applications where the extra pressure and temperature resistance provided by the shell is not required, and where no separate liquid feed injection/flash evaporation takes place inside the heat exchanger. Applications include carbon capture and storage, energy storage, oil refining, petrochemicals and many more.

Unique HyperCut plate design improves thermal efficiency


Alfa Laval’s unique HyperCut heat transfer plates have many benefits:

  • 50% lower pressure drop over the distribution areas compared to the previous design. This makes it possible to either increase heat recovery, reduce the size of the heat exchanger or to lower the overall pressure in the process.
  • 30% higher mechanical strength and higher resistance to thermo-mechanical stress.
  • Improved flow and pressure distribution, which improves operability.

Ako to funguje


The recycle gas enters the heat exchanger at the bottom and passes the Spray Bars on its way into the plate pack. The liquid feed enters from the side and is sprayed into the gas by the Spray Bars. This ensures a perfect mix of liquid feed and recycle gas, which facilitates lifting and makes it possible to operate the unit on a high liquid-to-gas ratio for maximum yield.

The feed/gas mixture moves up through the plate pack while the reactor effluent travels in the opposite direction. The highly turbulent, counter-current flow ensures that most of the heat from the reactor effluent is recovered and heats the cold feed. The hot approach temperature can be as low as 25°C (45°F).

The outstanding heat recovery reduces the load on both the reactor heater and the cooling system compared to using other types of heat exchangers, thereby reducing both OPEX and CAPEX.
