Alfa Laval FrontLine is the premium range of heat exchangers used in dairy, food, beverage and other hygienic applications requiring gentle product treatment, long operating time or superior cleanability. In comparison to the Alfa Laval BaseLine range, also used for hygienic applications, the FrontLine range meets the highest demands on hygienic control and it is the superior choice for heat sensitive media. FrontLine has a flexible design and it is possible to rebuild the connections.
Alfa Laval FrontLine allows a flexible design with plates tailor-made for demanding hygienic applications. The plate pattern and the pressing depth are designed for gentle, uniform heat transfer for sensitive dairy, food and beverage products. The glue-free gaskets are made with FDA-compliant materials which are easy to maintain and have a long service life.
The frame is available for multi-section applications and is easy to disassemble for inspection, cleaning, and service. The connection plate corners are interchangeable and the heat transfer plates can easily be added or removed. This makes the FrontLine quick and easy to modify in the event that process conditions change.
Plate types for different hygienic needs
FrontLine is available with 3 different types of plates, all of which are designed for sensitive, hygienic applications and uncompromising cleanliness.
- Clip plate – The Clip plate has a chevron plate pattern designed for hygienic conditions. The entry points, the distribution area, and the shape and depth of the pressed plate pattern allow for optimal performance.
- Clip plate Gemini double wall – The Clip plate Gemini double wall consist of two plates pressed together.This prevents cross contamination between fluids in case of leakage through the plates.
- Clip plate WideStream – The Clip plate WideStream has a wider plate pattern with fewer contact points which makes it ideal for products containing pulp or fibres.
FrontLine’s plate pattern and pressing depth are designed for gentle, uniform heat treatment of sensitive dairy, food and beverage products. Examples of applications are:
- Pasteurization of yoghurt, ice cream, and beer
- Pasteurization of fruit juice with fibres
- Heating and cooling of viscous products
Alfa Laval BaseLine is recommended for less demanding hygienic applications.
Automatic model for easy use in pasteurization with high throughput
Alfa Laval’s FrontLine Automatic is an extended version that has a motor and a PLC based control system for automatic opening and closing of the heat exchanger. This is suitable for larger units in dairy pasteurization with high throughput where there is requirement for frequent inspection and cleaning.

Multi-section hygienic gasketed plate heat exchanger
How it works
The heat transfer area of a gasketed plate-and-frame heat exchanger consists of a series of corrugated plates, assembled between the frame and pressure plates, which retain the design pressure. The sealing between the plates is made of gaskets. For the highest thermal performance and to enable a very close temperature approach, fluids normally run counter-currently through the heat exchanger.
FrontLine is available with different plate configurations which are designed for hygienic needs. The pressing depth and the shape of the corrugation are all carefully designed and selected to achieve optimal performance.
The chocolate pattern distribution area ensures that the fluids are evenly distributed across the entire plate to avoid stagnant zones that can result in fouling. High flow turbulence between plates results in higher heat transfer; however, the consequence is pressure drop. Our thermal design engineers will help you design and select the model and configuration that is suitable for your application needs while delivering maximum thermal performance and minimizing pressure drop.
