Packinox plate-and-frame heat exchanger
An Alfa Laval Packinox plate-and-frame heat exchanger is the perfect choice for heat transfer duties in processes with large flows, high temperatures and high pressures. Its superior thermal performance lets you increase energy efficiency, grow profitability and minimize your environmental impact. A single Packinox heat exchanger outperforms systems consisting of multiple large shell-and-tubes, both in terms of heat recovery and investment costs.
Outstanding thermal efficiency
- Low operating cost – The exceptional heat recovery brings substantial energy savings.
- Low maintenance costs thanks to minimal fouling.
- Lower CAPEX – A single Packinox can replace several large shell-and-tube heat exchangers.
- Low pressure drop.
- Reliable, proven technology – More than 350 units in operation worldwide.
Improve efficiency in LDES applications with Packinox+
Packinox is also available in a plate-and-shell configuration.
Thanks to our new FlexFlow technology, a Packinox+ heat exchanger can be optimized for highly asymmetric flows and offers a range of flow configurations, including multi-stream arrangements, making it highly suitable for a broad spectrum of demanding process duties.

Packinox plate-and-shell heat exchanger
Alfa Laval Packinox is also available in a plate-and-shell configuration, which is suitable for applications with higher pressures and temperatures. The plate-and-shell model also features Alfa Laval´s patented Spray Bar system, which optimizes liquid injection in gas streams.
Imagine a more sustainable world. A world where it takes less to produce even more. A world where we efficiently meet our growing energy demands and simultaneously reduce CO2 emissions. Imagine a world where we can harness the power of natural resources, while preserving them at the same time. At Alfa Laval, we don’t just imagine this world. We’re building it – together with our customers and our partners.
How it works
The heart of an Alfa Laval Packinox plate-and-frame heat exchanger is a fully welded bundle of heat transfer plates. The hot and cold streams flow in alternate channels between the plates, and in opposite directions. The counter-current flow maximizes heat transfer and makes it possible to operate with crossing temperatures in a single unit.
The corrugation of the plates causes high turbulence in the media, thereby increasing heat transfer and minimizing fouling.
The overlapping welds on two of the sides of the plate bundle form solid walls. The other two walls are reinforced with side panels, held together by a large number of tie rods. This design allows an Alfa Laval Packinox plate-and-frame heat exchanger to be operated at high pressures and with a differential pressure of up to 70 bar.
A Packinox plate-and-frame heat exchanger can be configured to operate with more than two flows, meaning several media can be heated or cooled simultaneously. Each flow can have an individual number of channels and the channel gap can differ for the different media.
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.
